Participation in Working Groups

  • WG4 - Mechanobiological principles of rare and common diseases

Research Interests

Cellular and molecular basis of diabetes, regulatory proteins and genes in development of diabetes; determinations of the proteins and/or mRNAs involved in pancreatic beta cell regeneration and apoptosis, molecular pathology of the complications caused by diabetes in a variety of organs. The investigation of the relation between the clinical properties and genotypes of some susceptibility genes in type II diabetic patients. The running projects include the investigations on beta cell regeneration, apoptosis and stem cells; the regenerative effects of DPP4 inhibitors on islets cells and liver cells in experimental diabetes.
The molecular basis of cancer including the oncogenes, programmed cell death (apoptosis and autophagic cell death) and metastase related genes in patients with breast and ovarian cancers, and in cancer cell lines.

The studies based on nervous system include the taupathy models (Alzheimer’s disease) in primary neuron culture and the in vivo experimental models of medulla spinalis trauma. The running projects is on the Pituitary adenomas and acromegaly disease; to identify relationship between acromegaly patient’s response to treatment and genetic variations in the miRNA genes controlling the gene expression of HMGA2, AIP and SSTR2.
