RESEARCH

The Jiang’s research focuses on understanding the molecular mechanism of intercellular and intracellular signaling mediated by connexin channels and the functional importance of these channels in the lens, skeletal tissues and cancer metastasis. The ongoing research projects include: 1. Channel-dependent and –independent roles of connexins in lens differentiation and development, and in maintaining lens transparency; 2. Connexin hemichannels and integrins in mediating mechanotransduction process in osteocytes and bone tissues and in protecting cells against oxidative stress; 3. Connexin channels in suppression of cancer metastasis; 4. Structure-function of amino acid transporters and their roles in neurodegeneration and oxidative stress. Various biochemical, molecular, cellular and genetic approaches as well as cell and transgenic mouse models are established to address these questions.
