Bivalent Histone Modifications Orchestrate Temporal Regulation of Glucosinolate Biosynthesis During Wound‐Induced Stress Responses in Arabidopsis

open access: yesPlant, Cell &Environment, Volume 49, Issue 1, Page 450-473, January 2026.
ABSTRACT Glucosinolates (GSLs) are secondary metabolites central to plant defence in the Brassicaceae family. While the role of histone modifications in developmental gene regulation is well studied, their function in stress‐induced secondary metabolism remains unclear.

Mechanism of CO2 and NH3 transport through human aquaporin 1: Evidence for parallel CO2 pathways

open access: yesThe Journal of Physiology, Volume 604, Issue 1, Page 336-365, 1 January 2026.
Abstract figure legend The figure illustrates the permeation pathways for CO2, NH3 and H2O through AQP1. The panel on the left, with the wild‐type protein under control conditions, CO2 moves through monomeric pores (2 of 4 shown) but predominantly via an alternate pathway (perhaps the central pore of the tetramer).

Alternanthera philoxeroides (Mart.) Griseb Mitigates Age‐Related Depression in Mice Through Regulation of Oxidative Stress and Neurogenic Mechanisms

open access: yesAdvances in Pharmacological and Pharmaceutical Sciences, Volume 2026, Issue 1, 2026.
Depression adversely impacts daily life, with age‐related neurodegeneration being a significant contributing factor. Neurodegenerative alterations, often accelerated by oxidative stress, underlie depressive progression in advanced age. Our previous research has reported that Alternanthera philoxeroides (Mart.) Griseb (AP) exhibits promising antioxidant

Ergostanes and Cytochalasin From the Fruiting Bodies of Xylaria longipes Nitschke and Their Cytotoxicity Evaluation

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
Four ergostanes—ergosta‐7,22,24(28)‐trien‐3β‐ol (1), ergosta‐7,24(28)‐dien‐3‐one (2), ergosta‐7,22,24(28)‐trien‐3‐one (3), and ergosta‐4,6,8(14),22‐tetraen‐3‐one (4)—and one cytochalasin, zygosporin D (5), were isolated from Xylaria longipes. Two compounds, 2 and 3, are novel but have a similar structure to Compound (1), except for the keto group at ...

2, 5‐Diketopiperazine Derivatives From Coculture of Escherichia coli and Mogroside V

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
Escherichia coli (E. coli), a versatile bacterium, is also recognized for its ability to produce a range of secondary metabolites with significant biological activities. Especially in so‐called biotransformation processes, E. coli is frequently utilized to catalyze the conversion of substrate molecules into diverse compounds through biosynthesis and ...
