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

BMC 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

Frontiers 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

Cancer & 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

Frontiers 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.

, 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 WHY1–NADK3–PEX5 module confers drought tolerance by maintaining peroxisomal ROS homeostasis in Brassica napus

The Plant Journal, Volume 127, Issue 6, September 2026.
SUMMARY Drought severely limits rapeseed productivity, but the role of NAD kinase in this process remains unclear. Here, we identify BnaA07.NADK3 as a drought‐ and ABA‐inducible peroxisomal NADK in Brassica napus. Overexpression of BnaA07.NADK3 enhanced drought tolerance, whereas CRISPR/Cas9‐edited lines showed reduced drought tolerance ...

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

Biomedical 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 ...

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

Alzheimer'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.

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

Biology 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+
