A Semi‐Quantitative Yeast Complementation Platform for Characterizing Urea and Ammonia Transport by Membrane Channels

open access: yesCurrent Protocols, Volume 6, Issue 3, March 2026.
Abstract Yeast complementation assays provide a robust in vivo platform for characterizing the permeability and pH gating of transmembrane channels. This article details a liquid culture approach to quantify urea and ammonia transport using Saccharomyces cerevisiae deletion strains.

Warming‐Mediated Decreases in Nectar Quality Translate Into Lower Energy Reserves of the Monarch Butterfly (Danaus plexippus)

open access: yesGlobal Change Biology Communications, Volume 1, Issue 1, March 2026.
Warming caused a significant decrease in monarch fat mass, likely due to an observed reduction in sucrose concentration caused by warming of the nectar. Since sucrose fuels fall migration and overwintering, our results suggest climate warming may reduce migration success and overwinter survival.

A Unique Intercellular Feedforward Loop From HK1 to TGF‐β1 Promotes the Progression of Hepatocellular Carcinoma

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 3, March 2026.
ABSTRACT Hepatocellular carcinoma (HCC) typically emerges in a fibrotic premalignant liver milieu, and hepatic stellate cells (HSCs) represent the predominant cell subtype implicated in hepatic fibrosis. The crosstalk between HCC cells and HSCs has been demonstrated to affect HCC progression.

Gonadal Development in Larvae of the Paedomorphic Ambystoma mexicanum (Amphibia: Urodela)

open access: yesJournal of Morphology, Volume 287, Issue 3, March 2026.
This research analyzes the gonads of Ambystoma mexicanum larvae of both sexes, revealing significant changes such as the onset of vitellogenesis in females at 9 months of age and oocytes with signs of maturity at 12 months. In males, gonadal maturity occurs earlier, with a notable cephalocaudal and lateromedial testicular regionalization, and ...

Polydopamine‐Antibiotic Composite Coating for Antibiofilm Applications

open access: yesMacromolecular Bioscience, Volume 26, Issue 3, March 2026.
Antibiotic‐loaded polydopamine coatings are developed to combat biofilm‐forming bacteria on catheter surfaces. These coatings strongly inhibit Pseudomonas aeruginosa biofilm formation on diverse materials, including during continuous artificial‐urine flow, and can accommodate multiple antibiotics.
