Myocardial Infarction, Acute
Conditions
Brief summary
Cardiac-enriched micro-RNAs (miRNAs), micro RNA 208b and 133a(MiR-208b, MiR-133a)) corresponds to the health and disorders of the cardiovascular system. An intron of the cardiac myosin heavy chain gene MYH7 encodes miR-208b. It is found on chromosome 14 in humans. Identify new diagnostic biomarkers based on miRNAs, researchers examine the expression of miR-133a and 208b at various time points (04 hours, 08 hours, 12 hours, 24 hours, 48 hours) following the development of the infarct and compared it to the traditional myocardial infarction biomarkers cardiac troponine (cTnl) and Creatine kinase-MB (CK-MB).
Detailed description
The 98% of human genes are non-coding RNA, which is further divided into long non-coding RNA (lncRNA, \> 200 bp) and short non-coding RNA (200 bp, including microRNA (miRNA) and circular RNA). More than 2000 human miRNAs have been discovered, and it seems that they regulate around 60% of human genes.Through a number of pathways, miRNAs control the development, re-modelling, and regeneration of the heart as well as endothelial function, vasculo-genesis, and neoangiogenesis. 30% of the genes in the human genome are regulated by about 1000 miRNAs. Endogenous miRNAs are 19-22 nucleotide single-stranded RNA molecules that frequently target the 3' untranslated regions (3'-UTR) of mRNAs to regulate gene expression at the post-transcriptional level in physiological processes, disease development, and conditions like cancer, autoimmune and inflammatory diseases, neuro-degenerative diseases, and cardiovascular diseases. Cardiac-enriched miRNAs, MiR-208 in health and disorders of the cardiovascular system are investigated. Identify new diagnostic biomarkers based on miRNAs, researchers examine the expression of miR-133a and 208b at various time points (04 hours, 08 hours, 12 hours, 24 hours, 48 hours) following the development of the infarct and compared it to the traditional myocardial infarction biomarkers cTnl and CK-MB.
