Closed complex of the D-3-hydroxybutyrate dehydrogenase induced by an enantiomeric competitive inhibitor. [PDF]

, 2009
D-3-Hydroxybutyrate dehydrogenase (HBDH) from Pseudomonas fragi showed a strict stereospecificity to the d-enantiomer of 3-hydroxybutyrate (d-3-HB) as a substrate. The l-enantiomer acts as a competitive inhibitor, with a K(i) value comparable to the K(m)

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...
