The NAD kinase OsNADK1 affects the intracellular redox balance and enhances the tolerance of rice to drought

open access: yesBMC Plant Biology, 2020
Background NAD kinases (NADKs) are the only known enzymes that directly phosphorylate NAD(H) to generate NADP(H) in different subcellular compartments. They participate in multiple life activities, such as modulating the NADP/NAD ratio, maintaining the ...

NAD Kinases: Metabolic Targets Controlling Redox Co-enzymes and Reducing Power Partitioning in Plant Stress and Development

open access: yesFrontiers in Plant Science, 2018
NAD(H) and NADP(H) are essential co-enzymes which dominantly control a number of fundamental biological processes by acting as reducing power and maintaining the intracellular redox balance of all life kingdoms.

A feedback loop of PPP and PI3K/AKT signal pathway drives regorafenib-resistance in HCC

open access: yesCancer & Metabolism, 2023
Background Hepatocellular carcinoma (HCC) is a principal type of liver cancer with high incidence and mortality rates. Regorafenib is a novel oral multikinase inhibitor for second-line therapy for advanced HCC.

Enhancing β-Carotene Production in Escherichia coli by Perturbing Central Carbon Metabolism and Improving the NADPH Supply

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Beta (β)-carotene (C40H56; a provitamin) is a particularly important carotenoid for human health. Many studies have focused on engineering Escherichia coli as an efficient heterologous producer of β-carotene.

Rarely, eukaryotic lineages replaced mito NADK genes with horizontal transfer of α-proteobacterial nadK.

open access: yes, 2019
Choanoflagellates, euglenozoans, and the cnidarian Stylophora pistillata eukaryotic mito-clade NADK genes while also possessing nadk genes apparently acquired from different lineages of α-proteobacteria. These apparent cases of HGT thus appear to be “α2m”

A combined artificial intelligence–wet lab approach identifies a pivotal role of the NAD+–mitophagy axis on aging and neurodegeneration

open access: yesAlzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Emerging evidence points to a role of nicotinamide mononucleotide (NAD+) depletion and compromised mitophagy in aging and neurodegenerative diseases. We hypothesize that age‐dependent impairment of the NAD+–mitophagy axis contributes to brain aging and neurodegeneration.

Extramedullary relapse of multiple myeloma defined as the highest risk group based on deregulated gene expression data

open access: yesBiomedical Papers, 2015
Background: Multiple myeloma (MM) is characterized by malignant proliferation of plasma cells (PC) which accumulate in the bone marrow (BM). The advent of new drugs has changed the course of the disease from incurable to treatable, but most patients ...

Metabolic Regulation of Macrophages in Health and Disease

open access: yesMedComm, Volume 7, Issue 8, August 2026.
Extracellular metabolites drive metabolic rewiring of glucose, lipid, and amino acid pathways in macrophages, steering their polarization toward pro‐ or anti‐inflammatory phenotypes and shaping a wide range of disease processes. Macrophages from different tissues display distinct metabolic signatures, and therapeutic strategies that target these ...

MNADK, a novel liver-enriched mitochondrion-localized NAD kinase

open access: yesBiology Open, 2013
Summary NADP+ and its reducing equivalent NADPH are essential for counteracting oxidative damage. Mitochondria are the major source of oxidative stress, since the majority of superoxide is generated from the mitochondrial respiratory chain. Because NADP+
