Description

Application of LINC02178 as diagnosis and treatment marker of cervical cancer
Technical Field
The invention relates to the field of biomedicine, in particular to application of LINC02178 as a diagnosis and treatment marker of cervical cancer.
Background
Cervical cancer is the most common gynecological malignancy, and is the first among female genital tumors. According to the 2014 statistical data of the world health organization, the number of new annual cases of cervical cancer is about 52.8 ten thousand, the number of annual deaths is about 26.6 ten thousand, 85% of the patients occur in developing countries, and rural areas are higher than cities. According to the latest Cancer statistical data published by the national tumor center, the number of new cases of cervical Cancer in China is about 9.89 ten thousand in 2015 years and the number of annual deaths is about 3.05 ten thousand in 2015 years, and the data shows a trend of rising year by year and the onset of disease younger [ Chen W, Zheng R, Baade P D, et al. The occurrence of cervical cancer is closely related to various factors, such as early marriage, early childbirth, prolificacy and sexual disturbance, but Human Papilloma Virus (HPV) infection is considered as a necessary condition for the onset of cervical cancer, HPV screening is positive in 99.7% of cervical cancer patients, and the risk of HPV persistent infection of patients suffering from cervical cancer is more than 250 times that of HPV-negative [ Wentzensen N, Arbyn M.HPV-based clinical cancer screening-factors, diagnosis, and missierceptions [ J ]. Prev Med,2017,98:33-35 l; torre L A, Islami F, Siegel R L, et al, Global Cancer in who: burden and tresds [ J ]. Cancer epidemic Biomarkers Prev,2017 ]. After the fact that HPV infection is the important cause of cervical cancer is firstly determined in the seven eighties of the last century, students carry out deep research on the mechanism of inducing the cervical cancer by HPV infection, and therefore, diagnosis methods and treatment strategies aiming at the cervical cancer are developed, including sensitive and specific precancerous diagnosis methods, targeted immunoprophylaxis measures and treatment methods, and the survival and life quality of cervical cancer patients are greatly improved.
With the development of modern biological detection technology and the continuous and deep research on the pathogenesis of tumors, various molecules in various biological processes related to tumorigenesis, such as nucleic acid, protein, carbohydrate, lipid, small molecule metabolites and even free tumor cells in blood, can be used as important tumor markers, and provide definite bases for clinical prevention, diagnosis and treatment. In cervical cancer, several tumor markers have been found to be used for clinical prevention of cervical cancer.
Ki-67 and p16INK4a are two common molecular markers for analyzing the proliferation state of tumor cells and the malignancy degree of tumors. Wherein Ki-67 is not expressed in silent GO phase cells but is highly expressed in G1, S, G2 and M phase cells, so it can be widely used to analyze the proliferative activity of cells to assess tumor progression [ Endl E, Gerdes J.the Ki-67protein: stimulating for and an unknown function [ J ] Exp Cell Res,2000,257(2): 231-; meanwhile, because the expression pedigree is wide, the tumor marker serving as a specific tumor marker still has certain defects, and other molecular markers are needed for auxiliary diagnosis in clinic. p16INK4a, a cyclin-regulating protein, specifically binds CDK4 and CDK6 to inhibit its activity and phosphorylation of downstream pRb, regulate cell cycle progression and cell differentiation processes; it has been found that p16INK4a expression is positively correlated with HR-HPV persistent infection and cervical tumor pathological grading, and has certain guiding value for patient post-operative HPV clearance and persistent infection [ Koh J, Enders G H, Dynlash B D, et al. Tumour-derived p16 alloys encoding proteins infection in cell-cycle inhibition [ J ] Nature,1995,375(6531): 506-.
The proExC antibody (BD Co.) specifically recognizes the nuclear protein MCM2 and the topoisomerase TOP2A complex induced by HPV infection. In cervical gland and squamous cell dysplasia, the cellular S-phase gene induced by the E7 oncogene promotes high expression of TOP2A and MCM2 in the nucleus, while TOP2A can combine with 6 MCM2 molecules to form a stable structure retained in the nucleus [ Santin A D, Zhan F, Bignoti E, et al. Gene expression profile of primary HPV16-and HPV 18-induced early stage receptors and nuclear specificity peptides: identification of non-catalytic molecular markers for nuclear specificity peptides and therapy [ J. Virology,2005,331 (269): 291) ]. Because it is not expressed in normal cervical epithelial cells, but is significantly highly expressed in HPV-induced squamous cells with active proliferation, it can be clinically used to distinguish atypical hyperplasia from similar changes such as incomplete squamous cell development or atrophy.
HPV DNA integrity and stability are mainly maintained by the capsid protein L1 and L2 together forming a stable protective shell. Among them, the L1 protein can also promote the invasion of virus particles into mucosal basement membrane zone cells or cervical epithelial cells by recognizing corresponding receptors on host cells. Expression of the L1 protein is continuously detected during mild to moderate dysplasia with HPV infection, but expression of the L1 protein gradually disappears as the degree of cervical carcinogenesis progresses [ McMurray H R, Mccanced J.human papillomavir type 16E6 organisms TERT gene transcription degradation of c-Myc and release of USF-mediated expression [ J ]. J Virol,2003,77(18): 9852-). Therefore, the disappearance of the expression of the HPV-L1 indicates that the viral genome is integrated in the host genome, and the diagnosis of the CIN3 stage of cervical cancer can be realized.
Lanminin-5 is a tumor marker closely related to tumor invasion, and the expression of the Lanminin-5 gene is closely related to the tumor progression in various malignant tumors. In the process of cervical cancer, the Lamin-5 is mainly expressed in the early stage of tumor, especially in the skin lesion of micro-infiltration, so that the method can be used for detecting the early stage of cervical squamous cell infiltration. MIB-I has an expression pattern similar to that of Ki-67, i.e., tumor cells that are active in a proliferative state with significantly high expression in stages of GINS, and detection in combination with Ki-67 can be used to assist in the analysis of the periodic state in which the tumor cells are located. Therefore, MIB-1 is another important indicator for detecting the proliferative activity of cells in the course of atypical hyperplasia.
In summary, although many tumor markers are currently used for clinical diagnosis of cervical cancer, tumor markers are constitutively expressed under normal conditions or increased in non-malignant tumor diseases, and thus lack tumor specificity. Therefore, the search of tumor specific antigens as biomarkers for the early diagnosis and prognosis determination of clinical cervical cancer is urgently needed.
