1801por Boes, Adrien, Brunel, Jean Michel, Derouaux, Adeline, Kerff, Frédéric, Bouhss, Ahmed, Touze, Thierry, Breukink, Eefjan, Terrak, Mohammed“…The GTase domain of bifunctional penicillin-binding proteins (PBPs) of class A, such as Escherichia coli PBP1b, belong to the GTase 51 family. These enzymes play an essential role in PG synthesis, and their specific inhibition by moenomycin was shown to lead to bacterial cell death. …”

1806por Garber, Scott, Rainey, William E, Rege, Juilee, van Rooyen, Desmaré, Lopez, Antoine-Guy“…In primary cultures of human adrenal cells BMP4 inhibited the ability of ACTH to increase cortisol production (↓75%), as well as CYP11B1(↓65%) and CYP17A1 (↓57%) expression. CONCLUSION: Our findings indicate that the human adrenal has outer cortex localized expression of BMP4 that could play a paracrine/autocrine role in zone-specific production of aldosterone vs. cortisol through BMP4 selective inhibition of CYP17A1 and CYP11B1. …”

1808por Gruemmer, Ruth, Motejlek, Karin, Berghaus, Daniela, Weich, Herbert A, Neulen, Joseph“…Vascular endothelial growth factor (VEGF) produced by granulosa cells and secreted into the follicular fluid plays an essential role in this process. On the other hand, soluble VEGF receptor-1 (sFlt-1) produced by endothelial cells acts as a negative modulator for the bioavailability of VEGF. …”
