miRNA in Scleroderma

microRNA or miRNA is an ultra short chain RNA produced by eukoryotic cells for epigenetic post transcriptional silencing of mRNA by binding to complementary regions. miRNA-7 downregulation may lead to excessive expression of Type I collagen leading to localised scleroderma and keloids. In comparison with the normal skin tissues, miRNAs were aberrantly expressed in limited cutaneous scleroderma and diffuse cutaneous scleroderma skin tissues as well. Supplementation of the microRNA results in the decrease of collagen expression in scleroderma fibroblasts.

About Me

As a Dermatologist and Informatician my research mainly involves application of bioinformatics techniques and tools in dermatological conditions. However my research interests are varied and I have publications in areas ranging from artificial intelligence, sequence analysis, systems biology, ontology development, microarray analysis, immunology, computational biology and clinical dermatology. I am also interested in eHealth, Health Informatics and Health Policy.
