Scientific Interest(s):

Dr. Xinmin Li’s research focuses on the identification and characterization of genetic variations that affect complex diseases. Li takes an integrated genomic approach to examine the alteration of mRNA/miRNA expression, copy number variation, single nucleotide polymorphism and DNA-protein interaction by primarily using microarray-based technologies for initial screening and siRNA-mediated knockdown technologies for functional screening. His goals are to identify clinically significant genetic variations in several widely prevalent diseases including cancer and obesity. One of his ongoing research projects is to study the microRNA regulation of adipocyte differentiation. Using the combination of gene array/miRNA array profiling, bioinformatics and siRNA knockdown, Li and his colleagues have found that miR-17-92, a miRNA cluster that promotes cell proliferation in various cancers, can accelerate adipocyte differentiation by directly targeting a tumor suppressor, Rb2/p130.
