One-pot biosynthesis of 7β-hydroxyandrost-4-ene-3,17-dione from phytosterols by cofactor regeneration system in engineered mycolicibacterium neoaurum

open access: yesMicrobial Cell Factories, 2022
Background 7β-hydroxylated steroids (7β-OHSt) possess significant activities in anti-inflammatory and neuroprotection, and some of them have been widely used in clinics.

Serum Proteomic and Metabolomic Signatures of High Versus Low Physical Function in Octogenarians. [PDF]

open access: yesAging Cell
Circulating factors are strongly implicated in modulating biological aging. In this study we show that the serum proteomic and metabolomic profile of high functioning octogenarians suggests lower activation of SASP, preservation of the tryptophan‐kynurenic pathway, higher lipophosphatidyl cholines promoting mitochondrial function, and reduced ...

MMFuncPhos: A Multi-Modal Learning Framework for Identifying Functional Phosphorylation Sites and Their Regulatory Types. [PDF]

open access: yesAdv Sci (Weinh)
The functions of most phosphorylation sites remain unknown, which is the “bottleneck” of phosphorylation modification studies. Here, a state‐of‐the‐art method, MMFuncPhos, is developed to predict functional phosphorylation sites based on a multi‐modal deep learning framework.

Distal Tumors Elicit Distinctive Gene Expression Changes in Mouse Brain, Different from Those Induced by Arthritis [PDF]

open access: yes, 2009
Background: Tumor progression is characterized by high mutation rates, each mutation potentially generating an “alarm” signal. The brain is the main integrator of signals arising in the periphery from changes in homeostasis.

Glucose-6-phosphate dehydrogenase contributes to the regulation of glucose uptake in skeletal muscle [PDF]

open access: yes, 2016
The development of skeletal muscle insulin resistance is an early physiological defect, yet the intracellular mechanisms accounting for this metabolic defect remained unresolved. Here, we have examined the role of glucose-6-phosphate dehydrogenase (G6PDH)

The two PPX-GppA homologues from Mycobacterium tuberculosis have distinct biochemical activities [PDF]

open access: yes, 2012
Inorganic polyphosphate (poly-P), guanosine pentaphosphate (pppGpp) and guanosine tetraphosphate (ppGpp) are ubiquitous in bacteria. These molecules play a variety of important physiological roles associated with stress resistance, persistence, and ...

Therapeutic targeting in breast cancer for the treatment of lymph node metastasis: NADK.

open access: green
Metastasis is the major cause of death from cancer.  Metastasis to the lymph node (“regional” metastasis) generally precedes distant metastasis, and we recently demonstrated that metastasis to the lymph nodes is a likely prerequisite for metastasis to the central nervous system (CNS) in humans with breast cancer (1-8).

Functional identification and subcellular localization of NAD kinase in the protozoan parasite Giardia intestinalis

open access: yesRevista Colombiana de Química, 2019
Nicotinamide adenine dinucleotide phosphate (NADP) is an essential biomolecule that participates in the redox homeostasis and synthesis of signaling compounds. NAD kinase (NADK) (EC 2.7.1.23/2.7.1.86) is the only enzyme capable of synthesizing NADP. This

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 ...
