Current Research

We are involved in a wide range of research subjects related to membrane biology.

Basic Research

  • Mechanisms of Epithelial to Mesenchymal Transition (EMT) and Mesenchymal to Epithelial Transition (MET)
  • Role of Na,K-ATPase in epithelial tissue biogenesis and cancer
  • Biogenesis of tight junctions and desmosomes
  • Biology of prostate specific membrane antigen

Translational Research

  • Drug development and preclinical studies for EMT and MET
  • Nanotechnology-based drug delivery for leukemia
  • Targeted drug delivery for solid tumors
  • Studies on soluble biomarkers for cancer and inflammation

Current Projects

  • Nanotherapeutics for childhood leukemia
  • Preclinical and Clinical studies of novel drugs for kidney cancer treatment
  • Three-dimensional (3-D) cell culture models for studying early development of cancer
