Macrophage TRIM21 Inhibition Ameliorates Murine Acute Pancreatitis via PHB2‐Mediated Mitochondrial Stabilization

Advanced Science, EarlyView.
Macrophage‐derived TRIM21 drives the progression of AP via ubiquitin‐proteasome‐mediated degradation of PHB2, leading to impaired PHB2‐mediated mitophagy. Therefore, accumulation of cytosolic mtDNA hyperactivates the cGAS‐STING signaling axis, thereby amplifying inflammatory cascades.

Selective regulation of chemosensitivity in glioblastoma by phosphatidylinositol 3-kinase beta

iScience
Summary: Resistance to chemotherapies such as temozolomide is a major hurdle to effectively treat therapy-resistant glioblastoma. This challenge arises from the activation of phosphatidylinositol 3-kinase (PI3K), which makes it an appealing therapeutic ...

Hepatocyte BPGM Induces RET Lactylation and Macrophage Reprogramming to Promote Tumorigenesis in Hepatocellular Carcinoma

Advanced Science, EarlyView.
Mechanistic schematic diagram.BPGM promotes the expression level of RET by increasing the lactylation of RET‐K549 and inhibiting its ubiquitination levels in HCC cells. Furthermore, BPGM in HCC cells could also promote M2 polarization in macrophages through lactate secretion. Both of the mechanisms could promote the progression of HCC. ABSTRACT Aerobic

Phosphoinositide 3-kinase: friend and foe in cardiovascular disease

Frontiers in Pharmacology, 2015
Class I phosphoinositide 3-kinases (PI3Ks) are a family of lipid kinases activated by cell membrane receptors, either receptor tyrosine kinases (RTKs) or G protein-coupled receptors (GPCRs), to catalyze the production of the lipid second messenger ...

Interaction of mycobacterium tuberculosis with the host cells: a focus in the molecular mechanism involved in trafficking and autophagy [PDF]

, 2018
Tuberculosis (TB) is an ancient disease remaining a serious health threat worldwide. It is caused by Mycobacterium tuberculosis (Mtb), an acid-fast bacilli, non-sporulated, slow-growing, immobile and aerobic.

Chaperone‐Mediated Autophagic Degradation of USP9X in Macrophages Exacerbates Postmyocardial Infarction Inflammation and Cardiac Dysfunction

Advanced Science, EarlyView.
This study demonstrates that inflammatory stimuli induce the acetylation‐triggered, chaperone‐mediated autophagic degradation of ubiquitin‐specific peptidase 9 X‐linked (USP9X) in macrophages. USP9X acts as a macrophage “inflammation switch” after myocardial infarction (MI). USP9X loss destabilizes tumor necrosis factor receptor‐associated factor (TRAF)

A p85 isoform switch enhances PI3K activation on endosomes by a MAP4- and PI3P-dependent mechanism

Cell Reports
Summary: Phosphatidylinositol 3-kinase α (PI3Kα) is a heterodimer of p110α catalytic and p85 adaptor subunits that is activated by agonist-stimulated receptor tyrosine kinases.

Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation

Advanced Science, EarlyView.
Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical
