Description
Technical Field
The invention relates to a detection kit for auxiliary diagnosis of cervical cancer and application thereof, in particular to three detection kits for auxiliary diagnosis of cervical cancer and application thereof, and specifically relates to a kit for detecting methylation degree of a promoter region of a homologous gene of a murine retrovirus integration site 1 related to cervical cancer and application thereof.
Background
Cervical cancer (cervical cancer) is a malignant tumor that occurs in the female cervix, and is a relatively common disease with high mortality. Under the existing medical conditions, cervical cancer is difficult to completely cure, but if early discovery and early treatment can be achieved, most of the cervical cancer has better prognosis. At present, cervical cancer screening mainly adopts three methods, namely cervical scraping examination, cervical TCT smear examination and HPV detection, wherein the HPV detection has higher relative accuracy, and if the 3 examinations are all abnormal results, cervical biopsy can be generally performed to make clear diagnosis. Currently, HPV infection is the leading cause of cervical cancer, and other associated risk factors include genetics, multiple sexual partners, premature initiation of sexual life, multiple pregnancy and multiple birth, and immunodeficiency diseases. In the case of cervical cancer, the preferred treatment mode is hysterectomy, and the operation is followed by radiotherapy and chemotherapy, which is helpful for prolonging the survival time of the patient.
With the development of science and technology, genetic examination and treatment of tumors become the hot topic of the medical community, people find that there are proto-oncogenes and tumor suppressor genes in human cells, when these two genes are mutated due to some conditions, cancer will be generated, tumors are one of the manifestation forms of cancer, gene therapy is to eliminate cancer cells at fixed points, and essentially, cancer is a genetic disease, and the occurrence, development and recurrence of which are related to the mutation, deletion and malformation of genes. Cervical cancer is a complex disease caused by the combined action of genetic factors and environmental factors, and the search for cervical cancer related genes and further the elucidation of the genetic mechanism of the onset of cervical cancer has become a hotspot of current research. Although more and more medical research institutions pay attention to and develop etiology research of cervical cancer, and research mostly focuses on the correlation between the methylation level of the promoter region of the related candidate gene and the cervical cancer, the pathogenesis of the cervical cancer is still not completely elucidated, and the improvement of the prevention and treatment level of the cervical cancer is undoubtedly prevented.
The Murine Retrovirus Integration Site 1 Homolog (Murine Retrovirus Integration Site 1 Homolog, MRVI1) (chr 11:10, 573, 091-containing 10,693,988) gene is similar to the mouse tumor suppressor gene (Mrvi1), which is often disrupted by the mouse AIDS-related virus (MRV). The protein encoded by MRVI1(chr 11:10, 573,091-10,693,988) is a substrate for cGMP-dependent kinase 1 and can act as a regulator of IP 3-induced calcium release. Mouse studies have shown that MRV integration at Mrvi1 induces myeloid leukemia by altering the expression of genes important for myeloid cell growth and/or differentiation, and thus the genes may function as myeloid leukemia cancer suppressor genes.
At present, no kit for detecting methylation degree of a gene promoter region of a mouse retrovirus integration site 1 homolog related to cervical cancer and application related research reports are disclosed at home and abroad.

step three: the prophase preparation of pyrosequencing is that 2 mu L of reaction binding beads, 38 mu L of binding buffer solution and 40 mu L of PCR products are added into a 96-hole PCR reaction plate and fully and uniformly mixed for 10min at room temperature; starting a vacuum pump to absorb the binding beads and the PCR product suspension, and sequentially immersing the binding beads and the PCR product suspension in 70% ethanol, 0.2M NaOH and washing buffer solution for 5s respectively; turning off the vacuum pump, placing the binding beads on the probe and the PCR product in 40 μ L annealing buffer solution containing 1.5 μ L of sequencing primer, denaturing at 85 deg.C for 2min, cooling to room temperature, and annealing and hybridizing the primer and the template; calculating the dosage according to Pyrosequencing software sequence design information, and sequentially adding a substrate mixture, an enzyme mixture and four dNTPs (QIAGEN) into a reagent cabin; placing the reagent cabin and the 96-hole reaction plate into a Pyrosequencing detector (PyroMark Q96 ID, QIAGEN) for reaction;
step four: pyrosequencing, namely calculating the dosage according to Pyrosequencing software sequence design information, and sequentially adding a substrate mixture, an enzyme mixture and four dNTPs (QIAGEN) into a reagent cabin; then the reagent chamber and the 96-well reaction plate are placed into a Pyrosequencing detector (PyroMark Q96 ID, QIAGEN) for reaction, and methylation analysis is carried out by using Pyro Q-CpG software carried by a Pyrosequencing instrument.
