Abstract

In 1993 miRNAs were discovered during a research on Caenorhabditis elegans conducted by Victor Ambros and Gary Ruvkun. The gene lin-4 that played important role in development in C. elgans was observed not encoding any protein but a very small RNA molecule of just 22 nucleotides. Main objective of this review is to highlight the significance of miRNAs in regulating the expression of many genes, which are either directly or indirectly involved in many diseases. One of the major causes of illness and death in developed countries of the world is cardiovascular disease. Some of the miRNAs have certain role to play in heart that are not specified for heart. So miRNAs have been found to be in other tissues like fibroblasts, endothelial cells and smooth muscle cells that are part of physiological study of cardiovascular system. Adult heart has limited capacity of regeneration therefore lost cardiomyocytes due to myocardial ischemia or infarction can result in low performance of heart. miRNAs have been shown to play a role in apoptotic regulation of cardiomyocytes in vivo. Many studies have shown that miR146a and 155 are up regulated in peripheral blood mononuclear cells, synovial fibroblasts, synovial fluid and Th-17 cells from rheuma...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.

Cardiovascular Homeostasis

Cardiovascular regulation and homeostasis is important in maintaining health and dysfunction may lead to cardiovascular diseases. Nitric oxide and vascular endothelium are one of many molecules involved in the homeostatic mechanism. Here is the latest research on cardiovascular homeostasis.
