LC3B Mediated SETDB1‐Accounted Alcoholic Steatohepatitis via Lipidation‐Dependent LAP and Lipidation‐Independent Nuclear Stabilization

Advanced Science, EarlyView.
SETDB1 is progressively downregulated in ALD, correlating with disease severity. SETDB1 deficiency impairs LAP by disrupting Rubicon membrane localization, leading to defective lipid droplet clearance. Concurrently, loss of SETDB1 reduces nuclear LC3B, causing R‐loop accumulation and cGAS‐STING‐driven inflammation. Lipidated LC3B mediates LAP‐dependent

A conserved annexin A6–mediated membrane repair mechanism in muscle, heart, and nerve

JCI Insight, 2022
Membrane instability and disruption underlie myriad acute and chronic disorders. Anxa6 encodes the membrane-associated protein annexin A6 and was identified as a genetic modifier of muscle repair and muscular dystrophy.

Genome‐Wide CRISPR Screen Identifies a microRNA Orchestrating Pleiotropic Resistance to Targeted Therapy and T Cell Immunity in Melanoma

Advanced Science, EarlyView.
A genome‐wide microRNA CRISPR screen identifies miR‐18a as a master regulator of cross‐resistance in melanoma. Loss of miR‐18a activates the AJUBA–YAP/Hippo axis to confer BRAFi resistance and enhances THBS1–CD47 interaction to impair CD8+ T cell immunity. hnRNP A1 is identified as an upstream regulator of miR‐18a processing.

RNA Helicase DDX21 Controls CD4+ T Cell Proliferation and Promotes Inflammatory Bowel Disease via Translational Control

Advanced Science, EarlyView.
ABSTRACT Inflammatory bowel disease (IBD) is characterized by dysregulated T cell responses. RNA helicases, including DExD‐box helicase 21 (DDX21), are pivotal in RNA metabolism, but their role in T cell‐mediated pathology during IBD remains unclear. Here, we demonstrate that DDX21 expression in CD4+ T cells correlates with cell cycle and translation ...

CD4+ Tregs Drive Post‐Ischemic Sprouting Angiogenesis via Endothelial YY1/MAML1 Reactivation

Advanced Science, EarlyView.
ABSTRACT Microvascular complications of diabetes are chronic diseases of small vessels. We previously found that CD4+ regulatory T‐cells (Tregs) are markedly reduced in type 2 diabetes (T2D) after ischemic injury in both mice and humans, and that Treg deficiency in immunodeficient mice impairs vascular regeneration.

Regulation of Annexin I in Rheumatoid Synovial Cells by Glucocorticoids and Interleukin-1

Mediators of Inflammation, 2006
The glucocorticoid (GC)-induced antiinflammatory molecule annexin I is expressed in leukocytes and has antiinflammatory effects in animal models of arthritis, but the expression of annexin I in rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS)

STUDY OF APOPTOSIS OF IMMUNE CELLS IN TYPE 1 DIABETES MELLITUS

Медицинская иммунология, 2017
Type 1 diabetic mellitus (T1DM) is known to be associated with progressive destruction of β-cells of the pancreas. Dysregulated immunity and programmed cell death are an important link in pathogenesis of diabetes.

[Annexins in mitochondria].

Postepy biochemii, 2016
Annexins form a family of membrane- and calcium-binding proteins, widely distributed in vertebrates. Their interactions with membranes are regulated by changes of intracellular concentration of calcium ([Ca2+]in.), pH, and the presence of negatively charged phospholipids as well as cholesterol in membranes.

Annexin 2-mediated enhancement of cytomegalovirus infection opposes inhibition by annexin 1 or annexin 5

Journal of General Virology, 2007
Biochemical studies have suggested that annexin 2 (A2) may participate in cytomegalovirus (CMV) infection. In the current work, effects of A2 monomer (p36) and heterotetramer (A2t; p362p112) were investigated. Demonstrating a role for endogenous A2, the four stages of infection that were followed were each inhibited by anti-p36 or anti-p11 at 37 °C ...
