본 발명은 대장용종에서 대장암으로의 진행을 예측진단할 수 있는 바이오마커에 관한 것으로, 더욱 상세하게는 대장용종 환자보다 대장암환자에게서 발현양이 감소 또는 증가되는 단백질체 및 사이토카인 혈장 바이오마커와 이를 이용한 대장용종-대장암 진행예측 진단용 바이오키트에 관한 것이다.The present invention relates to a biomarker capable of predicting the progression from colon to polyp, and more particularly, to a biomarker capable of predicting the progression from colon to polyp, The present invention relates to a biocide for the diagnosis of colorectal cancer-colon cancer progression using the same.

대장암(Colorectal cancer, CRC)이란 대장에 생긴 암세포로 이루어진 악성종양으로, 전세계적으로 가장 흔한 암들 중 하나이면서 악성종양에 의한 주요 사망원인 4위에 해당하는 암이다. 대장암은 높은 열량의 섭취, 동물성 지방 섭취, 섬유소 섭취 부족, 비만 등이 원인이 되어 발생하는 것으로 알려져 있다. 초기 대장암의 경우에는 아무런 증상도 나타나지 않으나, 눈에 띄지 않는 장 출혈로 혈액이 손실되어 빈혈이 생길 수 있으며 간혹 식욕부진과 체중감소가 나타난다. 암이 진행된 경우에는 배가 아프거나 설사 또는 변비가 생기는 등 배변습관의 변화가 나타나기도 하고 항문에서 피가 나오는 직장출혈의 증세가 나타나기도 한다.
Colorectal cancer (CRC) is a malignant tumor consisting of cancerous cells in the large intestine. It is one of the most common cancers in the world and the fourth leading cause of death by malignant tumors. It is known that colon cancer is caused by high calorie intake, animal fat intake, lack of fiber intake, and obesity. Early colorectal cancer does not show any symptoms, but it can cause anemia due to inconspicuous intestinal bleeding, resulting in anorexia and weight loss. When the cancer progresses, there is a change in bowel habits such as a stomach ache, diarrhea or constipation, and rectal bleeding from the anus.

대장암은 대장점막이 비정상적으로 자라 사마귀모양의 혹으로 보이는 조직인 대장 안의 용종(Polyp)으로부터 생긴다. 용종을 제거하지 않으면 결국 악성으로 변할 수 있고, 결장과 직장의 벽을 뚫고 다른 곳으로 전이될 수 있다. 대부분은 비종양성용종이지만, 선종성용종(종양성용종)은 대장 점막세포의 유전자에 돌연변이를 유발하는 것과 연관되어 있고 이러한 돌연변이가 대장암과 직결된다. 용종의 크기가 클수록 악성 세포를 포함할 가능성이 커진다.
Colorectal cancer arises from polyps in the large intestine, a tissue that looks abnormally enlarged in the large intestine and appears as a wart-shaped lump. If the polyp is not removed, it can eventually turn into malignancy, which can penetrate the walls of the colon and rectum and be transferred to another location. Most of them are non-polyps, but adenomatous polyps (tumorous polyps) are associated with mutations in the genes of the colon mucosal cells, and these mutations are directly related to colon cancer. The larger the polyp, the more likely it is to include malignant cells.

대장내시경(colonoscopy)이 대장암의 초기발견을 위한 가장 민감한 접근법이긴 하나, 침습적 시술이고 많은 비용이 들며 위험하고 불편한 방법이기도 하다. 따라서 대장암의 집단선별 프로그램을 더욱 증진할 수 있는 새로운 바이오마커가 필요하다.Although colonoscopy is the most sensitive approach to the early detection of colorectal cancer, it is invasive, costly, and dangerous and inconvenient. Therefore, new biomarkers are needed to further promote the colonoscopy screening program.

지금까지 대장암이 혈액 단백질체의 변화와 관련이 있음을 증명하는 수많은 보고서가 있었음에도 불구하고, 잠재적으로 치료가능한 초기단계의 대장암에 대하여 고감도 또는 높은 특이성을 가진 혈액 바이오마커가 치료용으로서 유효성이 승인된 적은 없었다. 현재 직접적인 육안검사를 제외하고 대장암을 발견하기 위한 2가지 간접적 진단도구들이 있다: 하나는 DNA 테스팅처럼 대변을 기반으로 한 접근법인 반면에, 다른 하나는 혈액 내 태아성 암 항원(CEA)의 레벨을 검사하는 것을 포함한다. 그러나 이 방법들은 초기단계 대장암 환자들에 대한 민감도가 낮다는 단점이 있다. 다른 주요 단점은 전구물 병변(선종)을 무시한 채 오직 대장암환자들과 건강한 대조구들에게만 제한된 방법인 것이다.
Although there have been so many reports to date that colon cancer is associated with changes in the blood protein body, blood biomarkers with high sensitivity or high specificity for potentially treatable early stage colorectal cancer I have never been approved. Currently, there are two indirect diagnostic tools to detect colon cancer, except direct visual inspection: one is a fecal-based approach like DNA testing, and the other is the level of fetal carcinoma antigen (CEA) in the blood Lt; / RTI > However, these methods have the disadvantage that they are less sensitive to early stage colorectal cancer patients. Another major disadvantage is that it is limited only to colorectal cancer patients and healthy controls, neglecting bulb water lesions (adenoma).

대장암의 발병 및 성장의 가장 중요한 패러다임은 대장용종-대장암 변화이다. 따라서 침습이 발생하기 전에 주요 전암성 병변(용종)이 감지되거나 제거된다면 대장암은 효과적으로 통제될 수 있다. 따라서 대장용종 형성의 기저를 이루는 분자적 메커니즘을 설명하는 것이 매우 중요하다. 대장암에 관련된 특정 단백질, 특히 용종-종양에 관련된 단백질의 동정은 충분히 대장암의 진단 및 치료를 발전시킬 수 있다. 현재 의학적 프로토콜이 대장내시경 및 변잠혈시험(fecal occult blood) 같은 다양한 검사를 사용하여 초기의 대장암을 감지할 수 있으나, 대장용종으로부터 대장암으로의 진행을 예측하는 바이오마커가 개발된다면 더욱 편리하고 유익할 것이다.The most important paradigm for the onset and growth of colorectal cancer is colorectal - colon cancer. Thus, colon cancer can be effectively controlled if major pre-cancerous lesions (polyps) are detected or eliminated before invasion occurs. Therefore, it is very important to explain the molecular mechanism underlying colonic polyp formation. Identification of certain proteins involved in colorectal cancer, particularly those associated with polypectomy-tumors, can sufficiently develop the diagnosis and treatment of colorectal cancer. Although current medical protocols can detect early colorectal cancer using a variety of tests such as colonoscopy and fecal occult blood, it is more convenient if biomarkers are developed that predict progress from colon polyps to colorectal cancer It will be beneficial.

지금까지 대장암의 새로운 바이오마커를 찾아내기 위해 단백질체적 접근법을 시도하여 왔다. 2-D 전기영동은 암 바이오마커를 추출할 뿐 아니라 기술적인 제한에 상관없이 대장암 형성의 기저를 이루는 복잡한 생물학적 사건을 연구하는 가장 흔한 접근법들 중 하나이다. 대장암의 단백질 바이오마커를 찾기 위해 바이오유체(biofluid) 또는 대장조직을 이용하여 많은 연구가 선행되어 왔다. 또, 환자들의 용종과 암 뿐만 아니라 건강한 대장점막에서의 차별되는 단백질분석을 증명하는 몇몇 선행연구들도 있다. 그러나 지금까지 대장용종에서 대장암으로 변하는 동안 특이적으로 조절되는 단백질들은 대장암의 진단 바이오마커로서 동정된 바 없었다.
So far, attempts have been made to approach protein volume to find new biomarkers for colorectal cancer. 2-D electrophoresis is one of the most common approaches to study complex biological events that underlie colon cancer formation, regardless of technical limitations, as well as extracting cancer biomarkers. Much research has been done using biofluids or colon tissue to find protein biomarkers for colon cancer. In addition, there are several previous studies that demonstrate differential protein analysis in healthy colon and mucosa as well as in patients' polyps and cancer. Until now, however, proteins specifically regulated during conversion from colon to colon have not been identified as diagnostic biomarkers for colorectal cancer.

혈액 내 단백질 암 바이오마커의 발견이 복잡한 것은 검체 전반에 걸친 높은 다양성과 혈청 및 혈장 내에 존재하는 광역동적영역(broaed dynamic range)의 단백질들때문이다. 그럼에도 불구하고 혈액을 이용하는 대장암 바이오마커의 동정은 임상적인 관점에서 점막검체보다 용이하다. 혈장은 기본적인 검체일 뿐만 아니라 어떤 샘플에도 존재하는 가장 크고 깊은 인간 단백질체를 나타내기 때문에, 암의 혈장 바이오마커를 찾는 매우 다양하고 체계적인 조사가 진행중이다. 혈장 단백질체는 병의 진단 및 치료목적의 모니터링을 근본적으로 변혁시킬 수 있기 때문에 많은 관심을 받고있다.
The complexity of the discovery of protein cancer biomarkers in the blood is due to the high diversity across the specimens and the proteins in the serum and plasma that are in the broad dynamic range. Nevertheless, identification of colon cancer biomarkers using blood is easier than mucosal specimens from a clinical point of view. Plasma is not only a basic sample, but it also represents the largest and deepest human protein body present in any sample, so a very diverse and systematic investigation is underway to find plasma biomarkers for cancer. Plasma proteomics has attracted much attention because it can fundamentally change the diagnosis and treatment of diseases.

수많은 예비보고서들이 혈청/혈장의 신호들을 원인으로 시사했음에도 불구하고 지금까지 대장용종에서 대장암으로의 순차적인 진행을 증명했던 강력한 마커는 없었다. 게다가 대부분의 생화학 및 단백질체 연구들은 대장암 그 자체마커의 동정에 제한하고 있었다. 그러나 소수의 단백질체 연구들은 선종성용종증(adenomatous polyposis)에서 대장암으로의 진행을 알려주는 유용한 바이오마커들을 증명하였다. 와일드 등(Clin . Cancer Res.2010)은 대장암 검출의 대안으로서 22종의 혈청 마커 및 복합마커를 평가하였다. 혈청 마커조합의 높은 성과는 최종진단을 위한 대장내시경의 후속장치를 촉발시키면서 신규한 대장암 선별도구를 제공한 것이다. 게다가 실험한 22종의 마커들 중에서 15종은 대장용종에서 대장암으로 진행 중에 순차적으로 증가됨을 보였다. 레너한 등(J. Clin . Endocrinol . Metab.2010)은 순환되는 양이 많은 인슐린유사성장인자Ⅱ(IGF-Ⅱ)가 대장용종의 종양마커가 될 수 있고 94%의 고 민감도로서 증가하는 대장암의 위험과 관련이 있을 수 있음을 보여주었다. 로블릭 등(Cell . Mol . Life Sci.2004)은 인간 대장조직의 생성 및 성장 동안에 순차적인 단백질체의 변형을 증명하였고 46종의 증가(up-regulated)단백질 및 26종의 감소(down-regulated)단백질을 동정하였다. 또한 대장암 환자에게 HSP10의 과발현은 대장용종에서 대장암으로의 진행을 알려주는 지표로서 동정되었다. 최근에는 프로가스트린의 과발현과 혈액 내 고순환농도가 증식성 대장용종의 예측변수로서 인식되었다.
Despite numerous preliminary reports suggesting serum / plasma signals, there has been no strong marker that has so far proven sequential progression from colon polyps to colorectal cancer. In addition, most biochemical and proteomic studies have limited the identification of colon cancer markers. However, a small number of protein body studies have demonstrated useful biomarkers to signal the progression from adenomatous polyposis to colorectal cancer. Wild, etc. ( Clin . Cancer Res. 2010) evaluated 22 serum markers and complex markers as an alternative to colon cancer detection. The high performance of the serum marker combination provides a novel colon cancer screening tool that triggers a subsequent device for colonoscopy for final diagnosis. In addition, of the 22 markers tested, 15 showed progressive progression from colon polyps to colon cancer. Renner et al . ( J. Clin . Endocrinol . Metab . 2010) demonstrated that circulating amounts of insulin-like growth factor II (IGF-Ⅱ) can be tumor markers for colon polyps and increased sensitivity of 94% And that the risk of death could be related to the risk of death. Loblik et al . ( Cell . Mol . Life Sci. 2004) demonstrated sequential protein body modifications during the production and growth of human colon tissues and identified 46 up-regulated proteins and 26 down-regulated proteins. Also, overexpression of HSP10 in colon cancer patients was identified as an indicator of progression from colon polyps to colorectal cancer. Recently, overgrowth of progesterone and high circulating concentrations in blood have been recognized as predictive variables of proliferative colonic polyps.

최근의 단백질체 연구는 혈청 내 낮은 α-2-HS-glycoprotein(AHSG)의 농도가 증가하는 교모세포종(glioblastoma) 증식 및 간암과 연관성이 있음을 증명하였다. 더욱 중요한 것은 상기 단백질이 성장인자β를 변형시키는 데 반하여, 길항작용에 의해서 장 내 종양진행을 억제한다는 것이다. 그러나 정반대로, 선행 단백질체 연구에서는 여러 신경학적 진단을 받은 환자들로 구성된 대조군그룹과 비교하여 저등급 신경교종 환자들(low-grage gliomas)로부터 고농도 AHSG의 2가지 isoform을 발견하였다. 나아가 본 발명자들은 대장용종 환자에 비해 대장암 환자에게서 혈장 내 AHSG의 농도가 현저히 증가했음을 발견하였다.
Recent proteomic studies have demonstrated that glioblastoma proliferation and liver cancer are associated with increased serum α-2-HS-glycoprotein (AHSG) levels. More importantly, while the protein modifies growth factor beta, it inhibits intestinal tumor progression by antagonism. Conversely, a study of the protonated protein found two isoforms of high-grade AHSG from low-grade gliomas compared to the control group of patients with multiple neurological diagnoses. Furthermore, the present inventors found that the concentration of AHSG in plasma was significantly increased in patients with colorectal cancer compared with patients with colorectal polyps.

한편, 여러 라인의 증거들이 혈액 내 헤모글로빈 농도가 수많은 질병에서 중요한 임상적 역할을 한다고 증명해왔다. 예를 들어 헤모글로빈(Hb) 농도는 여러 암의 치료에서 방사선요법 또는 화학방사선요법의 결과에 대한 중요한 예측지수이다. 증가한 혈청단백질 헤모글로빈α소단위(HBA) 및 헤모글로빈β소단위(HBB)의 수준이 난소암 환자들에서 관찰되어왔다. 본 발명에서 서열번호 2의 헤모글로빈β소단위 증가(up-regulation)는 헵토글로빈(haptoglobin)이 혈장에서 에리스로사이트에서 해리된 자유Hb에 높은 친화력으로 결합하는 것을 고려할 때 혈장단백질 헵토글로빈α2 사슬(Hpα2)의 증가한 양에 밀접하게 관련되어 있으며 그 결과 산화활동을 저해한다고 할 수 있다. 3번의 개별적인 단백질체 연구를 통해 난소암 및 교모세포종의 순환하는 바이오마커로서 Hpα2를 동정하였다.
On the other hand, several lines of evidence have demonstrated that hemoglobin concentration in the blood plays an important clinical role in many diseases. For example, hemoglobin (Hb) concentrations are important predictors of the outcome of radiation or chemoradiotherapy in the treatment of multiple cancers. Increased levels of serum protein hemoglobin alpha subunit (HBA) and hemoglobin beta subunit (HBB) have been observed in patients with ovarian cancer. In the present invention, the up-regulation of hemoglobin in SEQ ID NO: 2 indicates that the plasma protein heptoglobin alpha 2 chain (SEQ ID NO: 2), when considering that haptoglobin binds with high affinity to free Hb dissociated from erythrocyte in plasma Hp < / RTI >< RTI ID = 0.0 > 2) < / RTI > Three separate protein studies have identified Hpα2 as a circulating biomarker of ovarian cancer and glioblastoma.

혈청의 LRG 증가는 난소암(ovarian cancer) 및 담도암(biliary tract cancer)환자들에서 이미 관찰되었으나, 본 발명자들은 대장암 환자들에서 처음으로 서열번호 1의 혈장단백질 leucine-rich α-2-glycoprotein(LRG)의 증가를 관찰했다. LRG는 세포생존 및 세포사멸의 요인으로 제시되었다. 이는 LRG가 대장암 세포의 생존인자이며, 세포가 화학방사선요법에 더욱 저항하게 만든다는 것을 암시하였다.
The increase in serum LRG was observed in patients with ovarian cancer and biliary tract cancer. However, the inventors of the present invention found that the plasma protein leucine-rich α-2-glycoprotein (SEQ ID NO: 1) (LRG). LRG was suggested as a factor of cell survival and apoptosis. This suggests that LRG is a survival factor for colon cancer cells and makes the cells more resistant to chemoradiotherapy.

암환자의 높은 혈액 내 면역글로불린 항체 및 순환면역 복합체 지수는 계속 보고되었고, 수많은 암에서 조절패턴을 다양하게 할 수 있는 종양마커로서 제시되었었다. 그러나 Ig 사슬을 바이오마커로서 제시하는 증거는 없었다. 본 발명에서 대장암의 강력한 바이오마커 및 대장용종으로부터의 진행을 밝히면서 서열번호 3인 Igα-2사슬C부분(IgA2C)의 혈장 내 수준이 증가하였다.
The high intravenous immunoglobulin antibody and circulating immune complex indices of cancer patients have been reported and presented as tumor markers that can vary the regulatory pattern in many cancers. However, there was no evidence to suggest Ig chains as biomarkers. In the present invention, plasma levels of the Ig alpha-2 chain C portion (IgA2C) of SEQ ID NO: 3 were increased while progressing from the strong biomarker and colon polyp of the colon cancer.

대장암 또는 용종증 환자의 높은 혈장단백질 키니노젠1(KNG1)의 수준이 증명되었었다. 이 결과는 대장암 환자의 KNG1이 대장용종 환자의 그것보다 더 높다는 점에서 대장용종으로부터 대장암으로의 진행에 가능한 역할을 제시할 수 있었다. 그러나 대조군 및 유방암 환자에 비교했을 때 유의하게 감소한 KNG1의 수준이 난소암 환자의 소변에서 발견되었다.
The level of high plasma protein Kininogen 1 (KNG1) in patients with colorectal cancer or polyposis has been demonstrated. These results suggest that KNG1 in patients with colorectal cancer is higher than that in patients with colon polyps, suggesting a possible role for progression from colon polyps to colorectal cancer. However, the levels of KNG1 significantly decreased in the urine of patients with ovarian cancer when compared to control and breast cancer patients.

최근에 C3 및 C9처럼 보체 캐스케이드(complement cascade)에 관련된 단백질들이 면역반응을 반영하면서 대장암 환자들의 혈장에서 증가하는 것으로 보고되었다. 본 발명자들은 대장암 환자들이 보체 캐스케이드의 대체경로에서 중요한 구성요소인 서열번호 4인 혈장 내 보체인자 B(complement factor B)의 수준이 증가하는 것을 발견하였다. C9 및 factor B의 종양형성 효과는 세포외기질 분해를 포함하고 그 결과 종양세포의 침습 및 이동이 발생하였다. 따라서 대부분의 보체 단백질이 발암을 촉진함을 고려해볼 때 대장암 환자의 혈장 내 C9 및 factor B의 수준의 증가는 대장암의 강력한 바이오마커임을 나타내는 것으로 사료되었다. 이제까지 암에서 factor B 감소에 대한 보고는 없었다.
Recently, complement cascade-related proteins such as C3 and C9 have been reported to increase in plasma of patients with colorectal cancer reflecting the immune response. The inventors have found that levels of complement factor B in plasma, which is an important component in the alternative pathway of the complement cascade, are increased in patients with colorectal cancer. The tumorigenic effects of C9 and factor B involved extracellular matrix degradation resulting in invasion and migration of tumor cells. Therefore, considering that most of the complement proteins promote carcinogenesis, it is considered that the increase of plasma levels of C9 and factor B in colorectal cancer patients is a strong biomarker of colorectal cancer. There has been no report of factor B reduction in cancer so far.

본 발명의 단백질체 연구는 대장용종 및 대장암 환자 사이에 차등조절되는 패턴을 보이는 4종의 아포리포 단백질(Apo A-I, Apo C-Ⅲ, Apo E 및 Apo M)을 동정하였다. 이들 중에 Apo E만이 대장용종 환자보다 대장암 환자의 혈장에서 더 높은 수준을 보였던 반면에, 다른 3종(Apo A-I, Apo C-Ⅲ, Apo-M)의 수준은 감소되었다. 최근에 Apo E는 종양세포의 증식 및 생존에서의 역할 때문에 난소암 및 유방암(breast cancer)의 잠재적인 마커로서 동정되어 왔었다. 또한 혈장 내 Apo A-I, A-Ⅳ의 수준의 감소도 난소암의 단백질 마커이다. 선행 연구에서는 환자의 매치된 인접 정상세포 및 용종조직보다 대장암 종양조직에서 Apo A-I, Apo C-Ⅰ, Apo-M의 단백질 수준이 낮음을 보고했었다. 본 발명은 처음으로 Apo C-Ⅲ가 대장용종 환자보다 대장암 환자에서 낮은 수준을 보임을 발견하였다. 이전의 연구는 췌장암 환자의 혈정 내 Apo C-Ⅱ 수준이 더 높았던 반면에 Apo C-Ⅲ은 더 낮음을 암시하였다. 종합해보면 각 아포리포 단백질의 혈액 내 수준의 변화는 적어도 대장암에서는 특정한 것으로 사료되었다.
The proteomic studies of the present invention identified four types of apolipoproteins (Apo AI, Apo C-III, Apo E and Apo M) showing a pattern of differential regulation among colon polyp and colon cancer patients. Among these, only Apo E showed higher levels in the plasma of patients with colorectal cancer than in patients with colorectal polyps, while the levels of the other three (Apo AI, Apo C-III and Apo-M) were reduced. Recently, Apo E has been identified as a potential marker for ovarian cancer and breast cancer due to its role in tumor cell proliferation and survival. A decrease in levels of Apo AI, A-IV in plasma is also a protein marker of ovarian cancer. Previous studies have reported lower levels of Apo AI, Apo C-I, and Apo-M in colon cancer tumor tissues than matched adjacent normal cells and polyp tissues. The present invention has for the first time found that Apo C-Ⅲ is found to be lower in colorectal cancer patients than in colonic polyposis patients. Previous studies have shown that Apo C-Ⅱ levels in pancreas cancer patients are higher than those in patients with pancreatic cancer, while Apo C-Ⅲ is lower in pancreatic cancer patients. Taken together, changes in blood levels of apolipoproteins are considered to be specific for at least colorectal cancer.

최근에 혈액 내 레티놀 결합단백질(BRP4)수준의 변화는 여러 암과 관련이 있는 것으로 나타났다. 유의하게 감소된 RBP4 수준이 난소암, 유방암 환자들 및 새로 종양형성을 진단받은 아이들에게서 발견되었다. 반면에 췌장암(pancreatic cancer) 환자의 혈청 내 RBP4의 수준이 유의하게 증가함을 발견하였다. 감소한 혈장 내 BRP4의 수준은 그 결과 포유류에서 발암작용에 반하는 보호효과가 있는 레티노이드(retinoid)의 감소로 이어질 수 있다.
Recently, changes in blood levels of retinol binding protein (BRP4) have been associated with multiple cancers. Significantly reduced levels of RBP4 were found in ovarian cancer, breast cancer patients and children diagnosed with new tumors. Whereas the level of RBP4 in serum of pancreatic cancer patients was significantly increased. Decreased plasma levels of BRP4 may result in a reduction in retinoids that have a protective effect against carcinogenic effects in mammals.

최근에는 대장암 세포이동에서 겔솔린(GSN)의 자극하는 역할로 인하여 먼 장기전이 대장암 환자의 혈장 내 겔솔린의 수준이 증가되었음이 증명되었다. 그러나 본 발명에서는 용종증 환자에 비교했을 때 대장암 환자의 GSN 감소를 발견하였다. 이러한 관찰은 다른 유형의 종양에서 관찰된 이전의 발견점들, 예를 들면 GSN의 감소는 종양억제자로서 가능한 역할을 암시하면서 유방암 및 골육종의 발달을 초래함이 증명된 것과 일치한 것으로 사료되었다. 결론적으로 GSN의 감소는 대장발암현상의 초기에서부터 거의 만성적으로 일어나고 대장용종에서 대장암으로의 변화와 관련이 있음을 알 수 있었다.
Recently, it has been proven that the long - term prolongation of the level of gel solin in the plasma of colorectal cancer patients is due to the stimulating role of gelsolin (GSN) in colon cancer cell migration. However, the present invention has found a decrease in GSN in colon cancer patients as compared to polyposis patients. These observations seem to be consistent with previous findings found in other types of tumors, such as a reduction in GSN, suggesting a possible role as a tumor suppressor, leading to the development of breast cancer and osteosarcoma. In conclusion, the decrease of GSN was found to be almost chronic from the early stage of colonic carcinogenesis, and it was related to the change from colon polyp to colon cancer.

본 발명자들은 대장용종 및 대장암 환자들 사이에 차등 조절을 하면서 대장암 발병과는 관계가 없는 6종의 혈장 단백질을 조사하였다. The present inventors investigated six plasma proteins that were not related to the incidence of colorectal cancer while differentiating between colon and colon cancer patients.

A2M(α-2-macroglobulin)은 여러 병리학적 상태에 있는 환자들의 혈청에서 감소되는 것이 발견된 반면에, 혈청 내 A2M 수준의 증가는 일부 암의 경우에서 관찰되었다. 그러나 혈정 내 A2M의 수준감소가 유방암에서 일어난 것이 보고된 바 있다. 또 비타민E 결합단백질인 afamin의 혈액 내 감소가 난소암에서 관찰되었다.A2M (a-2-macroglobulin) was found to be reduced in the serum of patients in various pathological conditions, whereas elevated levels of A2M in serum were observed in some cancers. However, a decrease in the level of A2M in the blood has been reported to occur in breast cancer. In addition, a decrease in blood serum of afamin, a vitamin E binding protein, was observed in ovarian cancer.

대장암 환자의 세포성장 및 종양성장 및 전이같은 분화과정에 영향을 미칠 뿐 아니라 확산 및 이동를 유도하는 것으로 알려진 서열번호 7의 비트로넥틴(VTN)의 혈장 내 감소를 관찰하였다. 또한 유방암 환자의 혈액에서 감소한 VTN 수준도 검출되었다. 본 발명은 대장암 환자의 혈장 내 VTN 수준의 감소를 확인하는 신규한 발명이다. Platelet reduction of Vitonetin (VTN) of SEQ ID NO: 7, which is known to affect proliferation and migration as well as affecting cell growth and tumor growth and metastasis in colorectal cancer patients, was observed. Also, decreased levels of VTN were detected in the blood of patients with breast cancer. The present invention is a novel invention for confirming the reduction of the level of VTN in plasma of patients with colorectal cancer.

서열번호 8의 알파-1-안티트립신(AACT)은 단백질분해효소 활성을 억제하는 알파글로불린 당단백질이다. 이 단백질은 간에서 생성되고 염증반응 중에 유도되는 급성기 단백질(acute phage protein)로 알려져 있고, 나아가 이 단백질의 결핍은 간질환과 관련이 있어왔다. Alpha-1-antitrypsin (AACT) of SEQ ID NO: 8 is an alpha globulin glycoprotein that inhibits proteolytic enzyme activity. This protein is known to be an acute phage protein that is produced in the liver and induced during the inflammatory reaction. Furthermore, deficiency of this protein has been associated with liver disease.

이전의 증거에서는 서열번호 6의 ZAG(zinc-α-2-glycoprotein)가 전립선암 및 암 카켁시아(cancer cachexia)의 혈청과 소변 바이오마커로서 잠재성이 있음을 암시해왔다. 본 발명은 대장암 환자의 ZAG 감소를 최초로 관찰한 신규한 발명이다. Previous evidence has suggested that ZAG (zinc-alpha-2-glycoprotein) of SEQ ID NO: 6 has potential as a serum and urine biomarker for prostate cancer and cancer cachexia. The present invention is a novel invention for the first time observing the reduction of ZAG in patients with colorectal cancer.

혈청 내 TTR(transthyretin) 수준의 감소는 초기단계의 난소암과 대장암 전이의 지표로 알려져왔으나, 대장용종 환자보다 대장암 환자들의 TTR 수준의 감소가 대장암 진행의 증가한 위험을 잠재적으로 나타낼 수 있다.
Reduced levels of serum TTR (transthyretin) have been shown to be an indicator of early stage ovarian cancer and colorectal cancer metastasis, but a decrease in TTR levels in colorectal cancer patients may potentially represent an increased risk of colorectal cancer progression .

본 발명자들은 대장용종 또는 대장암 환자들의 혈장에서 사이토카인/케모카인에 대해 프로파일링한 후, 대장용종 환자와 비교했을 때 대장암 환자에게서 현저한 증가(p<0.05)를 보이는 3종의 사이토카인(IL-8,IP-10 및 TNF-α)을 성공적으로 동정하였다(표 3, 도 5). After profiling for cytokines / chemokines in the plasma of patients with colorectal or colorectal cancer, the present inventors have identified three cytokines (ILs) that show a significant increase (p < 0.05) in colorectal cancer patients as compared to colonic polyps -8, IP-10 and TNF-a) were successfully identified (Table 3, Fig. 5).

많은 증거들에서 종양성장이 미생물 주위의 염증성 신호에 의해 촉진됨을 암시한다. 따라서 만성염증 환자들은 대장암 발달의 위험이 증가한다. 대장암 환자들에서 전염증성 사이토카인 IL-8 수준이 높은 것은 다른 조사들에 의해 이미 보고되었다. 그러나 가장 중요한 것은 혈장 내 IL(인터루킨)-8 수준이 대장용종에서 대장암으로 변화하는 동안에 이를 조절하는 기능을 암시하면서 순차적으로 증가함을 발견된 것이다.Much evidence suggests that tumor growth is facilitated by inflammatory signals around the microbe. Patients with chronic inflammation are therefore at increased risk for colon cancer development. High levels of proinflammatory cytokine IL-8 in colorectal cancer patients have already been reported by other studies. But most importantly, it has been found that IL-8 levels in plasma increase sequentially, suggesting the ability to regulate IL-8 levels during colonoscopic to colorectal cancer.

유사하게도 종양촉진 중에 염증성 과정을 조정하는 주요 사이토카인은 TNF-α(tumor necrosis factor-α)이며, 수많은 암의 개시 및 진행에 관여하는 중요한 매개자이다. 혈액 내 TNF-α의 수준이 높은 것은 대장암 환자에게서 자주 발견되어 왔으나, 본 발명은 최초로 대장용종에서 대장암으로 변하는 중에 TNF-α이 증가하는 혈액 내의 수준을 관찰하는 것이다.
Similarly, the major cytokine that modulates inflammatory processes during tumor promotion is tumor necrosis factor-alpha (TNF-alpha), an important mediator involved in the initiation and progression of many cancers. High levels of TNF-a in the blood have been found frequently in patients with colorectal cancer, but the present invention is the first to observe levels of TNF-alpha in the blood during the transition from colorectal to colorectal cancer.

또한 IP(인터페론감마-유도단백질)-10, CXC 케모카인 리간드10(CXCL10)도 자가면역 질환에서 염증에 대한 마커로서 제시된 바 있다. IP-10은 사람의 대장암 세포의 진행 및 전이에 중요한 역할을 하는 것으로 알려져 있고, IP-10의 과발현은 대장암 환자들의 대장조직에서 발견된 바 있다. 본 발명은 최초로 대장암 환자의 혈장 내 IP-10의 증가한 수준을 보고하며, 동시에 대장용종에서 대장암으로의 진행에 대한 가능성 있는 진단 바이오마커임을 나타내었다.
In addition, IP (interferon gamma-inducible protein) -10 and CXC chemokine ligand 10 (CXCL10) have also been proposed as markers for inflammation in autoimmune diseases. IP-10 is known to play an important role in the progression and metastasis of human colon cancer cells, and overexpression of IP-10 has been found in the colon tissues of patients with colorectal cancer. The present invention first reports an increased level of IP-10 in plasma of patients with colorectal cancer, and at the same time a potential diagnostic biomarker for progression from colorectal to colorectal cancer.

실시예Example 2: 이차원 전기영동 분석(2- 2: Two-dimensional electrophoresis analysis (2- DEDE analysis분석 ))

상기에서 수득한 총 60명 환자들(30명의 대장용종 환자들 및 30명의 대장암 환자들)의 혈장샘플을 이용하여 이차원 전기영동을 수행하였다. 간단히, IPG 스트립(pH 4-7,18cm; GE헬스케어,버킹엄셔,영국)을 효과적인 단백질체 분석을 위해 알부민을 제거하지 않은 완전한 혈장 단백질 43㎍ 및 7M 우레아(바이오베이직,온타리오,캐나다), 2M 티오우레아(시그마,세인트루이스,미주리,미국), 4% CHAPS(바이오베이직), 1mM PMSF(시그마), 20mM DTT(GE헬스케어), 2% IPG 버퍼(바이오라드)를 포함하는 재수화용액 350μL 을 담은 스트립홀더에서 26시간 동안 방치하여 재수화시켰다. IEF는 PROTEIN IEF Cell(바이오라드)을 따라 수행되었다: 250V에서 15분, 250-10,000V에서 3시간, 10,000V에서 6시간, 그 다음 2차원을 진행하기 전까지 500V에서 유지하였다. 초점을 맞춘 스트립은 6M 우레아, 2% SDS(제너리바이오텍,상하이,중국), 1% DTT, 30% 글리세롤(바이오베이직) 및 50mM Tris-HCl(pH 6.8)을 함유하는 용액에서 20분 동안 평형을 이루었고, 뒤이어 DTT를 2% 요오드아세트아미드 (바이오라드)로 대체한 것을 제외하고는 상기와 동일한 용액에 추가로 20분동안 더 배양하였다. 그 다음 2차원에서 분해를 위해 20×20cm 크기의 12% 폴리아크릴아미드겔 위에 겔스트립을 두었고, 14시간 동안 겔마다 15mA의 전압을 계속 흘려주면서 Laemmli SDS-불연속시스템을 이용하여 분획법을 수행하였다. 영상분석 및 펩티드 질량 핑거프린팅(PMF)을 위해 단백질이 분리된 총 60개의 겔을 실버스테이닝하여 시각화하였다.
Two-dimensional electrophoresis was performed using plasma samples from a total of 60 patients (30 colonic polyps and 30 colorectal cancer patients) obtained above. Briefly, IPG strips (pH 4-7, 18 cm; GE Healthcare, Buckinghamshire, UK) were coated with 43 μg of complete plasma protein and 7 M urea (BioBasic, Ontario, Canada) 350 μL of rehydration solution containing thiourea (Sigma, St. Louis, Missouri, USA), 4% CHAPS (Bio Basic), 1 mM PMSF (Sigma), 20 mM DTT (GE Healthcare), 2% IPG buffer The flesh was left in the strip holder for 26 hours to rehydrate. The IEF was performed according to PROTEIN IEF Cell (Biorad): 15 minutes at 250V, 3 hours at 250-10,000V, 6 hours at 10,000V, and 500V before proceeding to the second dimension. The focused strips were equilibrated for 20 min in a solution containing 6 M urea, 2% SDS (Generi Biotech, Shanghai, China), 1% DTT, 30% glycerol (BioBasic) and 50 mM Tris- , Followed by further incubation for 20 minutes in the same solution as above except that DTT was replaced with 2% iodoacetamide (biorad). The gel strips were then placed on 12% polyacrylamide gels of 20x20 cm size for dissolution in two dimensions and fractionation was carried out using a Laemmli SDS-discontinuous system with a constant flow of 15 mA per gel for 14 hours . A total of 60 gels separated from the protein for visual analysis and peptide mass fingerprinting (PMF) were visualized by silver staining.

1차원에서 pH 4-7 IEF 스트립을 이용하고, 2차원에서 12% w/v SDS-PAGE겔을 이용하여 인간 혈장단백질을 분리한 결과, 327개의 반점들이 감지되었다(도 1). 또, 두 그룹사이에 차등조절되는 24종의 단백질 변화가 두 겔에서 영상 및 PMF 분석을 이용하여 확인되었고(도 1), 확인된 세부사항은 [표 2]에 열거하였다. A human plasma protein was isolated using a pH 4-7 IEF strip in one dimension and a 12% w / v SDS-PAGE gel in two dimensions, resulting in 327 spots (FIG. 1). In addition, 24 protein modifications that were differentially modulated between the two groups were identified using image and PMF analysis on two gels (Figure 1), and the identified details are listed in Table 2.

대장용종 및 대장암 환자들 사이의 혈장단백질 조절 프로파일에 대한 전반적인 비교를 위해서 각 그룹의 30개 겔에 나타나는 반점들을 이용하여 산포도를 만들었다(도 2). 도 2의 산포도는 두 환자그룹 사이의 반점 밀도를 한눈에 비교하기 위해 작성되었다. X- 및 Y-축은 각 반점의 volume(%)를 나타낸다. 각 빨간색 반점 및 파란색 반점은 각각 대장용종 환자보다 대장암 환자의 활성화(C>A) 및 활성억제(C<A)된 단백질을 각각 나타낸다(p<0.05).
For an overall comparison of plasma protein regulation profiles between colonic polyp and colorectal cancer patients, scatterplots were made using spots appearing in 30 gels of each group (Fig. 2). The scatter plot of FIG. 2 was created to compare the density of spots between two patient groups at a glance. The X- and Y-axes represent the volume (%) of each spot. Each red spot and blue spot showed protein activation (C> A) and inhibition (C <A) protein in colorectal cancer patients, respectively (p <0.05).

실시예Example 3: 영상수집 및 자료분석 3: Image collection and data analysis

겔은 UMAX PowerLook 1120(맥시엄 테스놀로지,애크론,오하이오,미국)로 이미지화되었고, modified ImageMaster 2D 소프트웨어V4.95(GE 헬스케어)을 이용하여 수행된 그룹들 간의 이미지들을 비교하였다. 모든 겔에서 검출된 반점들은 대장용종 환자그룹의 겔에서 선택된 참조 겔의 반점과 매치되었다. 상대흡광도(relative optical density) 및 상대부피(relative volume)는 겔 염색 중간에 차이를 수정할 목적으로 산출되었고, 각 반점 강도부피(intensity volume)는 배경제거(background subtraction)와 전체 반점부피의 표준화(total spot volume normalization)에 의해 처리되었다. 그 결과 초래된 반점 부피비율(spot volume percentage)은 그룹간의 비교를 위해 사용되었다.
The gels were imaged with a UMAX PowerLook 1120 (Maxi Tester, Akron, Ohio, USA) and images were compared between groups performed using the modified ImageMaster 2D software V4.95 (GE Healthcare). The spots detected in all the gels matched the spots of the reference gels selected in the gel of the colonic polyp group. The relative optical density and relative volume were calculated for the purpose of correcting the difference in the middle of the gel staining and the intensity intensity of each spot was calculated by subtracting the background subtraction and the standardization of the total spot volume spot volume normalization. The resulting spot volume percentage was used for comparison between groups.

페르난데즈 등(1998)이 서술한대로 단백질 반점을 절제하여 트립신으로 분해한 다음 α-cyano-4-hydroxycinnamic acid(CHCA;시그마)를 포함한 50% 아세토니트릴/0.1% 트리플루오로아세트산과 혼합하여 MALDI-TOF분석(마이크로플렉스 LRF20, 브룩커 달토닉스)에 이용하였다. 600-3,000 m/z범위 이상인 스펙트럼마다 300shots을 수집하였고 트립신 자동분해 피크(m/z 842.5099, 2211.1046)를 이용하여 두 점 내부눈금에 의해 눈금이 매겨졌다. 피크 리스트는 Flex Analysis 3.0으로 만들었다. 피크를 뽑는데 이용한 역치는 단동위질량의 최소분리능은 500, S/N은 5였다. 매트릭스사이언스(http://www.matrixscience.com)에서 만든 검색 프로그램 MASCOT(마스콧서버2.3)이 사용되었고, 확률기반의 MOWSE(분자량검색)점수가 PMF를 위해 산출되었다. 자료검색을 위해 절단효소로서 트립신, 최대 하나의 손실된 절단, 완전한 변형으로서 요오드아세트아미드(Cys), 부분적 변형으로서 산화(Met), 단동위질량 및 질량 오차범위±0.1Da을 포함하는 파라미터들을 이용하였다. PMF의 허용기준은 확률점수이다:-10*Log(P), P는 관찰된 매치가 우연한 일이고 66이상인 점수는 유의한 확률이다(p<0.05).
Protein spots were excised and digested with trypsin as described by Fernandez et al. (1998) and then mixed with 50% acetonitrile / 0.1% trifluoroacetic acid containing α-cyano-4-hydroxycinnamic acid (CHCA; Sigma) Analysis (Microflex LRF20, Brockerdaltonics). 300 shots were collected for spectra above the range of 600-3,000 m / z and were scaled by two point internal scales using the trypsin autolysis peak (m / z 842.5099, 2211.1046). The peak list was created with Flex Analysis 3.0. The minimum threshold for single peak mass was 500 and S / N was 5. A search program MASCOT (Mascot Server 2.3) created by Matrix Science (http://www.matrixscience.com) was used, and probability based MOWSE (Molecular Weight Search) scores were calculated for the PMF. For data retrieval, we used parameters including trypsin as a cleavage enzyme, maximal one lost cleavage, iodoacetamide (Cys) as a complete strain, oxidation (Met) as a partial strain, single-acting mass and mass error range ± 0.1 Da Respectively. The PMF acceptance criterion is the probability score: -10 * Log (P), P is the probability that the observed match is a coincidence and a score of 66 or more is significant (p <0.05).
