Scientific Interest(s):

Dr. Shen Pang and his colleagues have used subtractive hybridization to identify genes that specifically expressed in a prostate-specific antigen (PSA) producing cell line, LNCaP. They have obtained three genes, and one of them, claudin-7 (CLDN-7), has shown effect in regulating the expression of PSA. The researchers characterized CLDN-7 and found that the expression of this gene is responsive to androgen. Because tissue-specific expression of PSA and androgen responsiveness are two of the most important properties for prostate cancer diagnosis and treatment, the function of CLDN-7 in these two respects should be important for prostate cancer research.

Pang and his colleagues identified that primary oral epithelial cells with low passages can be infected by several HIV strains: NL4-3, JRCSF and SX. Further studies demonstrated that 2-4 percent of ethanol can significantly enhance HIV infection of oral epithelial cells. Because oral epithelial cells are CD4-, the researchers studied the mechanism of this infection and found that the HIV envelope protein, gp120, is not required. These results help to explain the mechanism by which HIV crosses the CD4- epithelial cell layers before infecting the submucosal CD4+ T-cells or macrophages. The study helps elucidate HIV oral transmission.
