Jean Jiang, Ph.D.

Jean jiang 057 cropped-2


Dr. Jean 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. Various biochemical, molecular, cellular and genetic approaches as well as cell and transgenic mouse models are established to address these questions.

Ongoing research projects include: 

1. Channel channels in cancer metastasis and translation research

2. Connexin hemichannels and integrins in mediating mechanotransduction process in osteocytes and bone tissues and in protecting cells against oxidative stress 

2. Channel-dependent and –independent roles of connexins in lens differentiation and development, and in maintaining lens transparency
