Description

Hsa-miR-132 detection kit and detection method thereof based on AllGlo fluorescence probe quantitative PCR

Technical field

The present invention relates to MicroRNA, especially relate to a kind of hsa-miR-132 detection kit and detection method thereof based on AllGlo fluorescence probe quantitative PCR.

Background technology

MicroRNA (miRNA) is that a class is extensively present in the non-coding RNA molecule that is about 22 Nucleotide in eukaryotic cell, many pathological processes in organism have been participated in, by regulatory gene, express, in cell proliferation, apoptosis, grow, cytodifferentiation, in the processes such as metabolism, play a significant role, be embodied in miRNA process in nucleus and form initial primary transcribe pri-miRNA to pre-miRNA, after transport out nucleus, by shearing, form ripe miRNA, by forming with Ago albumen etc. the silencing complex that RISC(RNA induces), part suppresses or degraded said target mrna sequence, participate in gene expression regulation (Bartel DP.MicroRNAs:genomics, biogenesis, mechanism, and function[J] .Cell, 2004, 116 (2): 281-297).

Because miRNA is playing the part of key player under generation, development, prognosis judgement and many other diseases states of tumour, accurately detect its expression and be significant for the effect of research miRNA.At present, the method for detection miRNA mainly contains northern blot technology, Real-Time Fluorescent Quantitative PCR Technique, hybridization in situ technique, micro-array chip technology etc.Wherein, northern blot technology is one of early stage means of RNA detection, but its specificity and susceptibility are low, if sample rna content is low or have degraded, may can't detect; Hybridization in situ technique, for detection of tissue and the distribution situation of cell levels miRNA, carries out half-quantitative detection to miRNA simultaneously, the miRNA of place is accurately to detect low expression that it is not enough; The problems such as micro-array chip technology is a kind of high-throughout detection technique, can detect a large amount of miRNA of one or more samples simultaneously, but exist chip manufacturing time-consuming, and effort and mark cost are high, and detection sensitivity and specificity are low.

Real time fluorescent quantitative technology (RT-qPCR) is one of technology the most generally detecting for genetic expression at present, have easy fast, the feature such as the high and specificity of susceptibility is good.At present, comprise the quantitative fluorescent PCR two portions in miRNA reverse transcription and downstream for detection of the real time fluorescence quantifying PCR method of miRNA, wherein reverse transcription is divided into two kinds according to the difference of reverse transcription primer: homopolymeric tailing method and stem ring reverse transcription method; The detection of quantitative fluorescent PCR is divided into dye method and probe method, the probe that wherein detects at present miRNA mostly is Taqman-MGB probe (a kind of fluorescent probe of the short-movie section that is suitable for increasing), because ripe miRNA has the short and small feature of fragment, want special detection, probe method more has superiority, and in susceptibility and specificity, is better than dye method.Reverse transcriptase primer energy specific recognition based on loop-stem structure, the ripe miRNA sequence that increases, and the precursor of miRNA is not amplified, Taqman-MGB probe in detecting miRNA shortcoming is synthetic price, is unfavorable for promoting.

At present, AllGlo probe has been successfully applied to and has detected simplexvirus, hepatitis B virogene sudden change (Feng, Z.L.Yu, X.Y.Lu, Z.M.Geng, D.Y.Zhang, L.Chen, S.J.Rapid detection of the hepatitis B virus YMDD mutant using AllGlo ^tMprobes[J] .Clin Chim Acta, 2011,412 (11-12): 1018-1021), invasive aspergillosis (Wu, D.S.Shen, J.Z.Zhou, X.Q.Shen, S.F.Wu, X.M.The establishment and evaluation of diagnostic accuracy of AllGlo (TM) probe-based techniques for invasive aspergillosis[J] .Zhong hua Nei Ke Za Zhi, 2010,49 (2): 142-145), the detection such as K-ras transgenation, ankylosing spondylitis.

Studies have reported that and show aspect neural system research, thereby glucocorticosteroid reaches the effect of lowering glutamate receptor by suppressing the expression of miR-132.(H.Kawashima, T.Numakawa, E.Kumamaru, et al.Glucocorticoid attenuates brain-derived neurotrophic factor-dependent upregulation of glutamate receptors via the suppression of microrna-132expression[J] .J Neurosci, 2010,165:1301-1311) at present miR-132 in biological field function, more and more paid attention to.
