Research Interests:
- Epithelial Cell Biology/Ion channels in Reproductive health and diseases
- The epithelium is a continuous layer of cells that covers external body
surface and forms lining of body cavities and exocrine glands. Disturbances
of epithelial cell functions give rise to a wide spectrum of diseases as common
as diarrhea and as lethal as cancer. We are interested in understanding how
epithelial secretion may affect physiological functions, reproduction in particular,
and how defects in epithelial ion channels may lead to diseases and infertility.
Research topics:
- Functional genomics: investigation and functional elucidation of reproductive
tract-specific new genes
- Epithelial transport in the reproductive tracts and signaling mechanisms:
receptors, ion channels expression & regulation
- Epithelial-mediated body defense and regulation of immune response: mucosal
defense mechanisms in GI and reproductive tracts
- Epithelial cell proliferation and apoptosis: signal transduction in carcinogenesis
and cancer metastasis
- Stem cells and regenerative medicine: microenvironment affecting stem cell
differentiation into different lineages including neurons and epithelial cells
- Development of traditional Chinese medicine: pharmacological studies and rapid
screening of active ingredients by in vitro and in vivo functional assays
Techniques employed:
- Electrophysiology: patch-clamp, oocyte-clamp (with microinjection), short-circuit
current measurement
- Molecular Biology: DNA array, RT-PCR, northern and western blot analysis,
mammalian cell line transfection and expression
- Cell Biology: cell culture (primary and continuous cell lines) , immunohistochemical
and ELISA techniques, microfluometry, spectro-luminescence (for intracellular
ions and pH), and flowcytometry.
- Animal models: knockout mice of CFTR, iNOS, eNOS, nNOS; transgenic GFP-mice
