Arbeitsgruppe PD Dr. Amar Deep Sharma
The major aim of our laboratory is to develop molecular medicine approaches for the treatment of liver disease. To achieve this, we are utilizing interdisciplinary approaches involving cell culture disease modeling, mouse experiments and biomaterials from clinical samples. Over the years, our work has uncovered the functional relevance of small RNAs and growth factors during progression of acute and chronic liver diseases. Additionally, we have discovered that transcription-factor induced reprogramming in hepatic cells holds a great potential for the attenuation of liver fibrosis and cirrhosis. We are currently investigating the mechanisms underlying cell fate conversion of hepatic cells during reprogramming. A second focus of our group is to develop RNA therapeutics for amelioration of liver diseases. We are investigating the therapeutic potential of various types of RNAs such as viral RNA and messenger RNA in mouse models of liver diseases.
