Description

Long-chain non-coding RNA AFAP1-AS1 is preparing the application on Computer-aided Diagnosis of Breast Cancer and Index for diagnosis preparation
Technical field
The invention belongs to oncomolecularbiology field, be specifically related to the in situ hybridization probe of long-chain non-coding RNA AFAP1-AS1, detection reagent and application method thereof.
Background technology
The Human Genome Project and follow-up DNA element encyclopedia plan (The Encyclopedia of DNA Elements Project thereof, ENCODE) achievement in research shows, protein coding gene sequence only accounts for the 1-3% of human genomic sequence, and the transcribed sequence of the overwhelming majority is long-chain non-coding RNA (Long non-coding RNA, lncRNA) in human genome.LncRNA is present in various biology widely, and along with the rising of biological complex degree, in genome, the ratio of lncRNA sequence also correspondingly increases, and lncRNA is significant in organic evolution process in prompting.Along with lncRNA is constantly found, their function is annotated gradually, scientists finds that lncRNA extensively and actively participates in the function controlling of vital movement different aspects, as a brand-new field, has become new forward position, international life science field and focus.
LncRNA can be used as the various ways such as signal (signal), induction (guide), bait (decoy) or support (scaffold) molecule of functional protein, in the expression of chromatin reconstruct, genetic transcription, translation and the multiple levels regulatory gene such as protein modified, and play irreplaceable role comprising in the basic physiological processes such as growth, immunity, reproduction, the more important thing is, expression and the functional disorder of lncRNA be closely connected with the mankind's various diseases comprising malignant tumour together with.Therefore, the function of further investigation lncRNA, disclose the genetic information transfer mode and expression regulation network that are mediated by lncRNA, not only can again annotate from the angle beyond protein coding gene and illustrate genomic structure and fuction, deeply find essence and the rule of vital movement, also be expected to the pathogeny comprising multiple mankind's common disease of tumour from a new visual angle understanding, and provide new molecular marker and therapy target for the Clinics and Practices of these diseases.
The sickness rate of mammary cancer occupies first of female malignant, its sickness rate is started always in rising trend from late 1970s, the U.S. 8 women just have 1 people in life and suffer from breast cancer, and the also sustainable growth always in recent years of China's breast cancer incidence, become the great public health problem of current social, mammary cancer easily shifts, and patients with terminal prognosis is poor.Research shows, the generation development of this tumour is polygene participation, multi-step, multistage complex process, and LncRNA may also play an important role in the generation evolution of mammary cancer.We utilize lncRNA chip recently, construct the express spectra of lncRNA in breast cancer biopsy tissue and normal reference sample, therefrom screen the lncRNAs of some differential expressions in mammary cancer, verify through enlarged sample real-time fluorescence quantitative PCR, confirm that lncRNA AFAP1-AS1 (NCBI accession number:NR_026892) significantly raises at breast carcinoma, the detection preparation for this lncRNA may be used for the auxiliary diagnosis of mammary cancer.Subsequently, we increase sample further, have in the mammary cancer paraffin file sample of Clinical Follow-up data in 77 examples, the expression level of AFAP1-AS1 is have detected by the method for in situ hybridization (in situ hybridization), find that AFAP1-AS1 expresses high patient and more easily shifts, its survival time is shorter than this lncRNA and expresses low patient, therefore also may be used for the Index for diagnosis of mammary cancer for the detection preparation of this lncRNA.
