Clathrin-Mediated Entry of Grass Carp Reovirus
2026-09-13
Wang et al. used pharmacological inhibitors, transmission electron microscopy, and quantitative PCR to show that genotype III grass carp reovirus enters CIK cells through dynamin-dependent, clathrin-mediated endocytosis requiring endosomal acidification. The lack of inhibition by Latrunculin B under the tested conditions provides a useful negative control for interpreting actin cytoskeleton disruption during viral-entry studies.

MEK–ERK Signaling in Lupus Lung Hemorrhage
2026-09-12
This preprint identifies MEK1/2–ERK1/2 activation as a pharmacologically targetable driver of endothelial injury, altered hemostasis, and diffuse alveolar hemorrhage in pristane-induced lupus in susceptible B6 mice. Its inhibitor-comparison design separates the MEK–ERK axis from JNK and p38 signaling and connects pathway activity with apoptosis, Egr1 expression, tissue-factor regulation, and bleeding phenotypes.

Substrate Stiffness Drives Dentinogenesis via FAK
2026-09-11
Bai and colleagues show that substrate stiffness regulates odontoblast-like cell behavior and dentinogenic differentiation through a LAMB1–FAK–MEK1/2 signaling axis. The work links material mechanics to focal-adhesion signaling and provides a mechanistic framework for designing dental biomaterials that support reparative dentin formation.

Sex Differences in Angiotensin II Hypertension
2026-09-10
The reference study showed that chronic angiotensin II produced a substantially larger blood-pressure rise in conscious male mice than in female mice, while gonadectomy shifted the response in opposite directions. Telemetry, phenylephrine testing, and ganglionic blockade linked this sex difference to altered baroreflex control and a greater ganglion-dependent contribution to blood-pressure maintenance in males.

PTK6–SOCS3–mTOR Control of Uveal Melanoma Autophagy
2026-09-10
The reference study identifies a PTK6–SOCS3–mTOR regulatory axis that suppresses autophagy and supports uveal melanoma proliferation, migration, and invasion. Its combination of database screening, cellular perturbation, interaction analysis, and rescue experiments provides a mechanistic framework for interpreting autophagy-dependent tumor phenotypes.

PFHxS Hepatotoxicity via PPAR Signaling in Zebrafish
2026-09-09
This 2024 study combines transcriptomics, liver pathology, biochemical measurements, and causal perturbation to show that environmentally relevant PFHxS exposure disrupts liver development and function in larval zebrafish through PPAR-mediated signaling. Its pharmacological antagonist and PPAR morpholino experiments strengthen the interpretation that altered lipid regulation is mechanistically linked to PFHxS-induced hepatotoxicity.

Arachidonic Acid Supplementation and Humoral Immunity
2026-09-09
A 2025 EMBO Molecular Medicine study identifies dietary arachidonic acid as a potential vaccine adjuvant that accelerates neutralizing-antibody responses to rabies vaccination in mice and human volunteers. The work connects lymph-node lipid metabolism with PGI2–cAMP–PKA signaling, CD86 expression, and AID activation in B cells, offering a mechanistic framework for improving germinal-center responses.

Biomimetic Chromatography for Lung Permeability
2026-09-08
The reference study compares mass-spectrometry-compatible immobilised artificial membrane liquid chromatography and open-tubular capillary electrochromatography for modelling pulmonary drug permeability. Its findings support IAM-LC-MS as a robust screening approach while showing that OT-CEC-MS can add information about phospholipid-specific drug–membrane interactions.

Metal-Free Carbon Nanozyme Assay for ALP Detection
2026-09-08
The reference study develops a metal-free carbon-dot nanozyme assay in which alkaline phosphatase hydrolysis of pyrophosphate releases catalytic activity and produces a colorimetric turn-on signal. Its kinetic analysis identifies pyrophosphate as a noncompetitive inhibitor at a site distinct from the principal catalytic region, enabling sensitive ALP measurement while reducing metal-ion interference.

PET Imaging of Gut Therapies in Hepatic Encephalopathy
2026-09-07
This study introduces [18F]PBR146 micro-PET/CT as a noninvasive method for comparing gut-directed interventions in chronic hepatic encephalopathy. Regional imaging suggested a benefit from Bifidobacterium but not fecal microbiota transplantation, while behavioral and systemic inflammatory measures showed no significant group differences.

HMGCS2, LysoPC, and Pulmonary Fibrosis
2026-09-07
Yang et al. identify injured type II alveolar epithelial cells as a major source of accumulated lysophosphatidylcholines in experimental pulmonary fibrosis and connect this lipid disturbance to fibroblast activation. Their data establish an HMGCS2–PPARα–CPT1A/CPT2 axis that links epithelial lipid degradation with fibrotic progression, while also defining a framework for species-specific LysoPC validation.

Ibotenic Acid Toxicity in Mice: Dose and Time Effects
2026-09-05
A 2026 Toxin Reviews study provides an integrated in vivo analysis of ibotenic acid toxicity in mice, linking dose and exposure time to behavioral changes, serum biochemical disturbances, c-fos activation, and reduced Nissl bodies. The findings help define acute toxicity boundaries for neuroscience research while cautioning that an acute poisoning model should not be equated with a chronic neurodegenerative disease model.

GSK3 Inhibition as Host-Directed TB Control
2026-09-04
The 2024 iScience study identifies glycogen synthase kinase 3 (GSK3) as a host pathway that supports intracellular Mycobacterium tuberculosis growth. By combining phenotypic screening, CRISPR and siRNA validation, pharmacological inhibition, and phosphoproteomics, the authors establish a mechanistic framework for host-directed tuberculosis therapy.

Interpretable Radiopathomics in Gastric Cancer
2026-09-04
This multicenter study developed a radiopathomics signature that combines baseline computed tomography with digital H&E pathology images to predict response to immunotherapy-based combination therapy in gastric cancer. Its strong validation performance, survival stratification, and association with immune features support multimodal, interpretable biomarkers while highlighting the need for prospective and technically standardized validation.
