Mitochondrial NADK, a Novel Functional Mediator of Tau Toxicity in Alzheimer's Disease [PDF]
Abstract Tau was first described in a 1975 PNAS paper from Marc Kirschner's lab as a brain protein that stimulates the polymerization of tubulin into microtubules (https://doi.org/10.1073/pnas.72.5.1858). Unbeknown at that time was the fact that tau is the building block of neurofibrillary tangles, and a central player in the pathogenesis of Alzheimer ...

Downregulation of NAD Kinase Expression in β-Cells Contributes to the Aging-Associated Decline in Glucose-Stimulated Insulin Secretion. [PDF]
Adequate NADK/NADK2 level is essential to the proper functioning of redox and folate cycles and the purine biosynthesis pathway, and as well as maintenance of GSIS response. During aging, diminished NADK/NADK2 expression alters the metabolic status quo, increasing AICAR production. The latter activates AMPK and suppresses GSIS.

NMRK2–YAP–NADK axis preserves redox protection against myocardial ischemia/reperfusion injury [PDF]
Substantial oxidative stress during myocardial ischemia/reperfusion (I/R) injury precipitates cell death and heart failure, for which translatable redox therapies remain scarce.

De Novo Biosynthesis of Antidepressant Psilocybin in Escherichia coli. [PDF]
Our work achieved de novo synthesis of antidepressant psilocybin in a single engineered Escherichia coli cell. By constructing the P450 PsiH variants with N‐terminal hydrophobic domain modifications, improving the supply of precursor tryptophan and cofactor NADPH, enhancing the electron transfer (ET) pathway and the final methylation step, and ...

NFATc1-mediated activation of the pentose phosphate pathway and cell cycle dysregulation collectively drive tumor progression [PDF]
The pentose phosphate pathway (PPP) supplies abundant reducing equivalents and biosynthetic precursors to support the rapid proliferation of tumor cells. An increased PPP flux is a hallmark of metabolic reprogramming in tumors. Although nuclear factor of

Knockdown of NADK promotes LUAD ferroptosis via NADPH/FSP1 axis [PDF]
Abstract Background Lung cancer is a serious threat to human health and is the first leading cause of cancer death. Ferroptosis, a newly discovered form of programmed cell death associated with redox homeostasis, is of particular interest in the lung cancer, given the high oxygen environment of lung cancer.

Adipose tissue macrophage-derived miR-690 modulates adipocyte precursor cell maintenance and adipogenesis [PDF]
Obesity is intricately linked to various metabolic diseases; however, some individuals maintain metabolic health despite being classified as obese. A critical factor underlying this paradox is the expansion of white adipose tissue (WAT), which can occur ...

Transcriptional Isoforms of NAD+ kinase regulate oxidative stress resistance and melanoma metastasis [PDF]
Metastasizing cancer cells encounter a multitude of stresses throughout the metastatic cascade. Oxidative stress is known to be a major barrier for metastatic colonization, such that metastasizing cancer cells must rewire their metabolic pathways to ...

NADPH-Related Enzymes and Cancer: Facts and Insights Into the Application of Immunohistochemistry. [PDF]
During tumorigenesis and metastasis, cancer cells initiate antioxidant defense mechanisms to prevent irreversible damage, thereby sustaining tumor growth. The functionality of reactive oxygen species (ROS)–scavenging proteins is dependent on nicotinamide adenine dinucleotide phosphate (NADPH), which is regulated by specific metabolic enzymes, which are
