Navigating the landscape of protein folding and proteostasis: from molecular chaperones to therapeutic innovations.

Protein folding is a fundamental process ensuring that polypeptide chains acquire the correct three-dimensional structures required for biological function. This complex journey from nascent polypeptides to mature proteins is tightly regulated by the cellular proteostasis network-an integrated system of molecular chaperones, folding enzymes, and degradation machineries. Disruptions in this network lead to dysproteostasis, a pathological state implicated in a growing list of human diseases, including neurodegenerative disorders, metabolic syndromes, and cancer. In this review, we provide a comp

LAMP5 modulates IRF4 stability and nuclear transport: a critical mechanism in myeloma progression and therapy.

Multiple myeloma is a malignant hematopoietic neoplasm characterized by unclear molecular mechanisms and lack of highly effective targeted therapies for clinical application. Interferon regulatory factor 4 (IRF4) is a well-known core transcription factor that regulates the progression of myeloma, but the molecular mechanisms underlying its protein homeostasis regulation are unknown. Our research shows that lysosomal-associated membrane protein 5 (LAMP5) interacts with IRF4 and prevents its degradation through the autophagy-lysosome pathway, thereby facilitating the progression of myeloma. Addi

Ageing, Cellular Senescence and Neurodegenerative Disease.

Ageing is a major risk factor for developing many neurodegenerative diseases. Cellular senescence is a homeostatic biological process that has a key role in driving ageing. There is evidence that senescent cells accumulate in the nervous system with ageing and neurodegenerative disease and may predispose a person to the appearance of a neurodegenerative condition or may aggravate its course. Research into senescence has long been hindered by its variable and cell-type specific features and the lack of a universal marker to unequivocally detect senescent cells. Recent advances in senescence mar

Noncanonical SQSTM1/p62-Nrf2 pathway activation mediates proteasome inhibitor resistance in multiple myeloma cells via redox, metabolic and translational reprogramming.

Multiple Myeloma (MM) is a B-cell malignancy characterized by the accumulation of clonal plasma cells in the bone marrow, with drug resistance being a major cause of therapeutic failure. We established a carfilzomib-resistant derivative of the LP-1 MM cell line (LP-1/Cfz) and found that the transcription factor NF-E2 p45-related factor 2 (Nrf2; gene symbol NFE2L2) contributes to carfilzomib resistance. The mechanism of Nrf2 activation involved enhanced translation of Nrf2 as well as its positive regulator, the autophagy receptor sequestosome 1 (SQSTM1)/p62. The eukaryotic translation initiatio

Cellular Senescence and Aging: Mechanisms, Disease Convergence, and Therapeutic Frontiers.

Cellular senescence, a stress-induced, irreversible cell cycle arrest coupled with a proinflammatory secretory phenotype, has emerged as both a central driver of aging and a tractable therapeutic target. Although acute senescence contributes beneficially to tumor suppression and wound healing, chronic accumulation of senescent cells sustains systemic inflammaging and accelerates organ dysfunction. This review synthesizes current progress in aging biology into a unified mechanistic and translational framework. We first examine how primary aging hallmarks, such as genomic instability and epigene

Novel Insights into the Links between N6-Methyladenosine and Regulated Cell Death in Musculoskeletal Diseases.

Musculoskeletal diseases (MSDs), including osteoarthritis (OA), osteosarcoma (OS), multiple myeloma (MM), intervertebral disc degeneration (IDD), osteoporosis (OP), and rheumatoid arthritis (RA), present noteworthy obstacles associated with pain, disability, and impaired quality of life on a global scale.
