Description
Technical field
The present invention relates to gene engineering technology field, be a kind of LncRNA ENST00000509938.1 and preparation or diagnosis
Agent or medicine or test kit and application i.e. ENST00000509938.1 and preparation or diagnostic agent or medicine or test kit and application.
Background technology
Acute myocardial infarction (acute myocardial infarction, AMI) is as coronary heart disease
Type the most serious in (Coronary heart disease, CHD), its morbidity is anxious, case fatality rate is high, forms people's health
Serious threat.It is raw that the diagnosis of acute myocardial infarction at present depends on clinical manifestation, Electrocardiographic dynamic change and serum more
Thing mark.Diagnosing acute myocardial infarction and preventing the most earlier, is always the important topic of our research.And with
The Human Genome Project and complete the development with biochip technology, the Disease-causing gene of many single-gene disorders is found, and should
Use in the middle of the Clinics and Practices of disease.And AMI exists as a kind of disease affected by multiple nature-nurture factor, hereditism
Effect in AMI morbidity is the clearest and the most definite.
Long-chain non-coding RNA (long non-coding RNAs, lncRNA) is that a class transcript length is more than 200nt
RNA molecule, the most not encoding proteins, transcribed by rna plymerase ii and formed through variable sheer, and transcriptional level is compiled less than protein
Code gene, had been considered as the most once " noise " of subgenomic transcription.It has proven convenient that lncRNA epigenetics, transcriptional control, turn
After record, the multiple aspect such as regulation and control controlling gene is expressed, and plays a significant role in various biological process, including lipid metabolism, moves
Pulse atherosclerosis formation, fetal development and the generation etc. of tumor,
Long-chain non-coding RNA (long noncoding RNA, lncRNA) is that a class can be sent out during various biological
Wave the macromole ncRNA of regulating and controlling effect.It is widely distributed, and length is typically greater than 200 bases, owing to lacking effective open reading
Frame (ORF) and without or seldom have the ability of encoding proteins.As a uncharted field in molecular biology, lncRNA be with
The form of RNA plays the effect that controlling gene is expressed in the multiple aspects such as epigenetics, transcriptional control, post-transcriptional control.
As the important component part of mammalian transcription group, the function of lncRNA needs to further investigate at present.Originally lncRNA
It is considered as the by-product transcribed of RNA polymerase II, is subgenomic transcription " noise ", not there is biological function.But in recent years
Result of study show, lncRNA important function in cell normal physiological activity and participate in multiple disease and send out
Exhibition.LncRNA can be reconstructed by Genomic Imprinting, chromatin, the mechanism such as regulation and control, mRNA degraded and translational control of shearing implement it
Function.
