The Role of Mitochondrial NADPH-Dependent Isocitrate Dehydrogenase in Cancer Cells [PDF]
Isocitrate dehydrogenase 2 (IDH2) is located in the mitochondrial matrix. IDH2 acts in the forward Krebs cycle as an NADP+-consuming enzyme, providing NADPH for maintenance of the reduced glutathione and peroxiredoxin systems and for self-maintenance by reactivation of cystine-inactivated IDH2 by glutaredoxin 2. In highly respiring cells, the resulting

Computational design of highly stable and soluble alcohol dehydrogenase for NADPH regeneration [PDF]
Abstract Nicotinamide adenine dinucleotide phosphate (NADPH), as a well-known cofactor, is widely used in the most of enzymatic redox reactions, playing an important role in industrial catalysis. However, the absence of a comparable method for efficient NADP + to NADPH ...

NADPH provides the reducing power for decomposition of reactive oxygen species (ROS), making it an indispensable part during ROS defense. It remains uncertain, however, if living cells respond to the ROS challenge with an elevated intracellular NADPH ...

The Binding of NADH and NADPH to Bovine‐Liver Glutamate Dehydrogenase [PDF]
The binding of NADH and NADPH to bovine liver glutamate dehydrogenase has been studied using circular dichroism (CD) and fluorescence spectroscopy, under comparable conditions of enzyme concentration. Spectroscopic titrations have been analysed using non‐linear least‐squares techniques to determine dissociation constants and parameters for the ...

Lipid synthesis from acetate-1-14C by rat skin was inhibited 44-56% by 2.5 × 10-4m dehydroepiandrosterone (DHA) in vitro with or without addition of glucose in the incubation medium. This inhibition affected all the lipid fractions examined (hydrocarbons,

Glucose‐6‐phosphate dehydrogenase, NADPH, and cell survival [PDF]
AbstractGlucose‐6‐phosphate dehydrogenase (G6PD) is the rate‐limiting enzyme of the pentose phosphate pathway. Many scientists think that the roles and regulation of G6PD in physiology and pathophysiology have been well established as the enzyme was first identified 80 years ago.

The Ca2+-Regulation of the Mitochondrial External NADPH Dehydrogenase in Plants Is Controlled by Cytosolic pH. [PDF]
NADPH is a key reductant carrier that maintains internal redox and antioxidant status, and that links biosynthetic, catabolic and signalling pathways.

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