Stephen M. Black is a Regents Professor with Georgia Regents University’s Department of Obstetrics and Gynecology (learn more). Over the course of his career, Stephen M. Black has been published in over 150 medical journal articles featuring his findings from dozens of medical research projects. Currently Stephen M. Black and his integrated cardiovascular laboratory have several research projects that are extramurally funded (funded by outside parties) or pending funding. His focus has been on understanding how reactive nitrogen species (RNS) generation alters function both in vitro (in a living organism) and in vivo (in a test tube environment). Below are some of the subjects that Stephen M. Black is currently researching:
Perinatal regulation of endothelial NOS
This study aims to understand how endothelial nitrous oxide synthase (eNOS) signaling is regulated in the pulmonary system during the perinatal stage. Stephen M. Black hopes that gaining an understanding of how ET-1 interactions mediate changes in a child’s pulmonary blood flow (PBF) following surgery might improve peri-operative treatment strategies to reduce short and long-term morbidity and mortality among children with congenital heart defects (CHD).
Perinatal regulation of TGF-beta1 during vascular remodeling
Abnormal structural development of the pulmonary circulation continues to lead to morbidity and late mortality for children born with CHD. Stephen M. Black hopes that this project will test the hypotheses that increased pulmonary circulation is due, at least in part, to a shear stress dependent increase in vascular endothelial growth factor (VEGF) expression mediated by increased activation of transforming growth factor-beta 1 (TGF-beta1), as well as that nitrous oxide (NO) plays a key role in the previously mentioned process. The resulting research will shed a light on which biomedical forces regulate the TGF-beta1/VEGF axis, which will help medical professionals such as Stephen M. Black develop new treatment strategies for children born with CHD.

[…] Last week’s blog post took a look at two areas that Stephen M. Black is currently researching: Perinatal regulation of endothelial NOS, and Perinatal regulation of TGF-beta1 during vascular remodeling. However, there are many more research projects on which Stephen M. Black and his integrated cardiovascular laboratory are focusing. Most of his research, which extramurally funded by outside parties, is intended to help the medical community gain a better understanding of how reactive nitrogen species (RNS) generations alters function both in a living organism (in vitro) and in a test tube environment (in vivo). Ongoing research projects that have not previously been discussed are: […]
