Impaired Chaperone-Mediated Autophagy Accelerates Intervertebral Disc Degeneration by Inducing MIDN Accumulation to Target TSC2 for Proteasomal Degradation. [PDF]
This graphical abstract illustrates how chaperone‐mediated autophagy (CMA) regulates intervertebral disc degeneration (IDD). Under normal homeostasis (B), CMA degrades cytoplasmic Midnolin (MIDN) to maintain proteostasis. Under inflammatory stress (A), impaired CMA leads to cytoplasmic MIDN accumulation.

LAMP2A-dependent chaperone-mediated autophagy enhances oxidative stress resistance in gastric cancer cells through selective degradation of accumulated oxidized DJ-1. [PDF]
Chaperone-mediated autophagy (CMA) promotes cancer cell survival by selectively removing oxidatively damaged proteins, yet its precise molecular mechanisms and role in redox adaptation remain incompletely understood.

A Lamp2a-linked RNA secreted by ADSCs prevents ENO1–lactylation–glycolysis feedback and cell malignant behavior in triple-negative breast cancer [PDF]
Triple-negative breast cancer (TNBC) is a subtype characterized by the absence of common BC receptors and is closely associated with a hypoxic tumor microenvironment. However, the mechanisms through which TNBCs adapt to hypoxia remain elusive. This study

Deficient chaperone-mediated autophagy in macrophages aggravates colitis and colitis-associated tumorigenesis in mice [PDF]
Chaperone-mediated autophagy (CMA) is a highly selective form of autophagy responsible for the degradation of specific cytosolic proteins within lysosomes. Recent research has established a significant correlation between CMA and colorectal cancer (CRC).

HSP90AA1 Facilitates Vascular Calcification in Chronic Kidney Disease Involving Chaperone-Mediated Autophagy [PDF]
Background: Chronic kidney disease (CKD) associated vascular calcification (VC) is a leading cause of cardiovascular mortality, partially driven by osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs). Chaperone-mediated autophagy (CMA)

High glucose-induced PLCG1 histone acetylation to promote ferroptosis by LAMP2A/HSPA8 in a diabetic nephropathy model [PDF]
Diabetic nephropathy (DN) is one of the most prevalent microvascular complications of diabetes mellitus. In the present study, the effects of PLCG1 DN, as well as its underlying molecular mechanisms associated with ferroptosis, were investigated.

Chaperone mediated autophagy is deficient in spinal motoneurons of ALS patients with TDP-43 proteinopathy [PDF]
Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease characterized by the selective loss of motor neurons (MNs), ultimately resulting in paralysis and respiratory failure within 3 to 5 years of onset. Fewer than 10% of ALS cases

Circulating Plasma Cells as a Minimally Invasive Adjunct to Bone Marrow Aspirates for Genetic Analysis of ER Stress and Autophagy in Multiple Myeloma: A Feasibility Study [PDF]
Background: Multiple myeloma (MM) is characterised by clonal expansion of plasma cells (PCs) in the bone marrow (BM). Disease assessment and monitoring typically rely on invasive, single-site procedures, such as BM biopsies (BMBs), which may inadequately
