Downregulation of FcRn promotes ferroptosis in herpes simplex virus-1-induced lung injury.

Cell Mol Life Sci

January 2025

School of Basic Medical Sciences, Xinxiang Medical University, #601 Jinsui Road, Xinxiang, 453003, Henan, China.

Article Synopsis
  • HSV-1 infection can lead to lung injury, and a study found that lower levels of FcRn (a protein) are linked to more severe lung damage caused by the virus.
  • The study revealed that HSV-1 increases the methylation of the FcRn gene, which reduces its expression by promoting DNMT3b, a protein that inhibits transcription through a specific region of the FcRn promoter.
  • Inhibiting ferroptosis (a type of cell death) with a drug helped reduce lung injury in cases affected by HSV-1, indicating that targeting FcRn might be a promising therapeutic approach.

School of Medical Engineering, Department of Cardiology of The First Affiliated Hospital of Xinxiang Medical University, Xinxiang Medical University, Xinxiang, 453003, Henan, China.

The research aims to investigate the mechanical response of footfalls at different velocities to understand the mechanism of heel injury and provide a scientific basis for the prevention and treatment of heel fractures. A three-dimensional solid model of foot drop was constructed using anatomical structures segmented from medical CT scans, including bone, cartilage, ligaments, plantar fascia, and soft tissues, and the impact velocities of the foot were set to be 2 m/s, 4 m/s, 6 m/s, 8 m/s, and 10 m/s. Explicit kinetic analysis methods were used to investigate the mechanical response of the foot landing with different speeds to explore the damage mechanism of heel bone at different impact velocities.

Background: Liver pathologies represent a spectrum of conditions ranging from fatty liver to the aggressive hepatocellular carcinoma (HCC), as well as parasitic infections, which collectively pose substantial global health challenges. S-palmitoylation (commonly referred to as palmitoylation), a post-translational modification (PTM) characterized by the covalent linkage of a 16-carbon palmitic acid (PA) chain to specific cysteine residues on target proteins, plays a pivotal role in diverse cellular functions and is intimately associated with the liver's physiological and pathological states.

Aim Of Review: This study aims to elucidate how protein palmitoylation affects liver disease pathophysiology and evaluates its potential as a target for diagnostic and therapeutic interventions.

Background: Adolescent idiopathic scoliosis (AIS) stands as the predominant spinal deformity in adolescents, manifesting symptoms including back pain, functional limitations, cosmetic worries, and respiratory dysfunction. At present, six approaches of scoliosis-specific exercises are globally practiced, encompassing Schroth exercise, the Scientific Exercise Approach to Scoliosis (SEAS), the Dobomed, the side shift exercise, active self-correction, and the Functional Individual Therapy of Scoliosis (FITS). However, there is no systematic review and meta-analysis comparing the efficacy of these six types of scoliosis-specific exercises on adolescent idiopathic scoliosis.

O-GlcNAc transferase promotes vascular smooth muscle calcification through modulating Wnt/β-catenin signaling.

FASEB J

December 2024

Xinxiang Key Laboratory of Metabolism and Integrative Physiology, School of Forensic Medicine, Xinxiang Medical University, Xinxiang, Henan, China.

Vascular calcification (VC), associated with high cardiovascular mortality in patients with chronic kidney disease (CKD), involves osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs). O-GlcNAcylation, a dynamic post-translational modification, is closely linked to cardiovascular diseases, including VC. However, the exact role and molecular mechanism of O-GlcNAc signaling in abnormal mineral metabolism-induced VC remain unclear.

State Key Laboratory of Medicinal Chemical Biology, Tianjin Key Laboratory of Protein Sciences, Cancer Biology Center, College of Life Sciences, Nankai University, Tianjin, 300071, PR China. Electronic address:

Photothermal therapy (PTT) is an innovative cancer treatment that leverages heat generated from near-infrared light exposure to induce tumor cell death. A major challenge in PTT is achieving precise delivery of the photothermal agent to tumor tissues to maximize efficacy and minimize off-target effects. In this study, we introduce a novel ligand-coupled photothermal reagent that addresses this challenge by leveraging the high-affinity HER2 affibody Z (referred to as Z), conjugated with indocyanine green (ICG) for targeted delivery.

School of Medicine, Pingdingshan University, Pingdingshan, China.

Primary myelofibrosis (PMF) is characterized by bone marrow fibrosis, but the underlying molecular mechanisms remain incompletely understood. Here, we investigated the role of lysyl oxidase-like 2 (LOXL2), an enzyme involved in extracellular matrix remodeling, in PMF pathogenesis. Analysis of bone marrow cells from PMF patients revealed significantly elevated LOXL2 mRNA expression compared to healthy controls, which was further validated using 2 independent Gene Expression Omnibus datasets (GSE26049 and GSE12234).
