SUMOylation regulates tumorigenesis and progression: Molecular mechanisms and therapeutic applications

Interdisciplinary Medicine, EarlyView.
SUMOylation, a dynamic post‐translational modification, acts as a master regulator at the heart of tumor malignancy. Our work delineates how the SUMOylation cycle—mediated by E1/E2/E3 enzymes and reversed by SENPs—orchestrates multiple hallmarks of cancer. The central pathway converges on three critical pathological axes: 1.

Harnessing energy metabolism for enhanced bone defect repair: Mechanisms and therapeutic strategies

VIEW, EarlyView.
This review addresses the critical challenge of bone defect repair by focusing on the underexplored role of cellular energy metabolism. It synthesizes regulatory mechanisms in bone‐forming cells and sums up innovative strategies—leveraging cell derivatives, active factors, and biomimetic scaffolds—to modulate metabolism for enhanced regeneration.

The Role of Pyruvate Kinase M2 in Cancer Metabolism

Brain Pathology, 2015
AbstractThe M2 isoform of pyruvate kinase is expressed preferentially in cancer cells over other pyruvate kinase isoforms. PKM2 is unique in its ability to be regulated allosterically by nutrients and growth signaling pathways, allowing cells to adapt their metabolic program to match physiological needs in different environments.

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Effects of Tepp-46 on dermal fibrosis in systemic scleroderma

Zhongguo Linchuang Yixue
Objective To explore the effects of Tepp-46, a pyruvate kinase M2 (PKM2) agonist, on the skin fibrosis of patients with systemic scleroderma (SSc) and its therapeutic effect on the SSc mouse models. Methods Full-thickness skin tissues of SSc patients and

MUC1-C oncoprotein regulates glycolysis and pyruvate kinase M2 activity in cancer cells.

PLoS ONE, 2011
Aerobic glycolysis in cancer cells is regulated by multiple effectors that include Akt and pyruvate kinase M2 (PKM2). Mucin 1 (MUC1) is a heterodimeric glycoprotein that is aberrantly overexpressed by human breast and other carcinomas.

Glycolytic metabolism of CD8+ T‐cells affects susceptibility to human leukocyte antigen‐mediated abacavir‐induced hypersensitivity

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Drug hypersensitivity reactions (DHRs) associated with a specific human leukocyte antigen (HLA) allotype do not manifest uniformly in all individuals within an HLA model population. This scenario highlights the complexity of predicting drug hypersensitivity reaction risk without considering additional factors ...

Cannabidiol and cannabigerol ameliorate steatotic liver disease via phosphocreatine buffering and lysosomal restoration

British Journal of Pharmacology, EarlyView.
Cannabidiol (CBD) and cannabigerol (CBG) alleviate hepatic steatosis in obese mice by shifting energy buffering towards phosphocreatine and enhancing lysosomal lipid degradation and trafficking. These effects are associated with increased creatine kinase activity and lysobisphosphatidic acid (LBPA) levels, highlighting a previously unrecognised ...

The role of pyruvate kinase M2 in anticancer therapeutic treatments (Review)

Oncology Letters, 2019
Cancer cells are characterized by a high glycolytic rate, which leads to energy regeneration and anabolic metabolism; a consequence of this is the abnormal expression of pyruvate kinase isoenzyme M2 (PKM2). Multiple studies have demonstrated that the expression levels of PKM2 are upregulated in numerous cancer types.
