Natural product virtual-interact-phenotypic target characterization: A novel approach demonstrated with Salvia miltiorrhiza extract

open access: yesJournal of Pharmaceutical Analysis
Natural products (NPs) have historically been a fundamental source for drug discovery. Yet the complex nature of NPs presents substantial challenges in pinpointing bioactive constituents, and corresponding targets.

Several Hfq-dependent alterations in physiology of Yersinia enterocolitica O:3 are mediated by derepression of the transcriptional regulator RovM [PDF]

open access: yes, 2017
In bacteria, the RNA chaperone Hfq enables pairing of small regulatory RNAs with their target mRNAs and therefore is a key player of post-transcriptional regulation network. As a global regulator, Hfq is engaged in the adaptation to external environment,

Inhibitory Activity of Conferone on FAK Activity and Glutamine Metabolism in Human Colorectal Cancer

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT Colorectal cancer (CRC) is a major global cause of death, with metastases and chemotherapy resistance contributing to poor outcomes. To identify natural compounds with anticancer potential against CRC and elucidate their action mechanisms, the cytotoxicity of 37 natural compounds was evaluated against the HCT116, leading to the identification ...

GLUL stabilizes N-Cadherin by antagonizing β-Catenin to inhibit the progresses of gastric cancer

open access: yesActa Pharmaceutica Sinica B
Glutamate-ammonia ligase (GLUL, also known as glutamine synthetase) is a crucial enzyme that catalyzes ammonium and glutamate into glutamine in the ATP-dependent condensation.

Cleavage of the apoptosis inhibitor DIAP1 by the apical caspase DRONC in both normal and apoptotic drosophila cells [PDF]

open access: yes, 2005
In Drosophila S2 cells, the apical caspase DRONC undergoes a low level of spontaneous autoprocessing. Unintended apoptosis is prevented by the inhibitor of apoptosis DIAP1, which targets the processed form of DRONC for degradation through its E3 ...

Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

open access: yesChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Targeting AQP5-mediated arginine deprivation in gastric cancer stem cells restores NK cell anti-tumor immunity

open access: yesCell Reports Medicine
Summary: Natural killer (NK) cells exhibit impaired anti-tumor activity upon entering the tumor microenvironment (TME); however, the precise mechanism(s) remains elusive.

Altered expression of glutamate signaling, growth factor, and glia genes in the locus coeruleus of patients with major depression. [PDF]

open access: yes, 2011
Several studies have proposed that brain glutamate signaling abnormalities and glial pathology have a role in the etiology of major depressive disorder (MDD).

Urinary felinine excretion in intact male cats is increased by dietary cystine [PDF]

open access: yes, 2008
Felinine is a branched-chain sulfur amino acid present in the urine of certain Felidae, including domestic cats. The objective of the present study was to determine if additional cystine and/or dietary N would increase felinine and N-acetylfelinine ...

ERM Inhibition Confers Ferroptosis Resistance through ROS‐Induced NRF2 Signaling

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
ERM inhibition disrupts ERM‐actin interactions, elevating ROS and triggering KEAP1 degradation, which stabilizes and activates NRF2. Nuclear NRF2 induces cytoprotective genes, notably HMOX1, enhancing redox buffering and suppressing lipid peroxidation to resist erastin‐induced ferroptosis.
