Research Interest
Nitric Oxide(NO) is essential in regulating vasodilation. Dr. Gladwin’s lab has discovered nitrite, as NO a reservoir, can be reduced to NO by hemoglobin. Molybdenum(Mo)-containing enzyme mitochondrial amidoxime reducing component 2(mARC2) has also been shown to chemically reduce nitrite to NO under hypoxic condition. I am focusing in establishing cell models by altering mARC2 expression in COS7, endothelial and smooth muscle cells to study the functions and mechanisms of mARC2 as nitrite reductase. The potential of sGC enzyme itself as a nitrite reducatse is under investigation.

The potential role of sGC modulators Bay 41 and Bay 58 compounds in the treatment of sickle cells symptoms by increasing fetal hemoglobin gene expression has been discovered by Gladwin’s lab. The molecular mechanisms and pathways involved in sGC modulators induced fetal hemoglobin gene expression in human primary erythroid progenitor cells will are being explored.
