Telomere Dysfunction and Proteostasis Decline Define Distinct Pathways of Cellular Senescence in the Human Respiratory Tract

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Telomere shortening occurs with age in the respiratory epithelium, but telomere dysfunction‐induced foci (TIF) accumulate only late in life. In contrast, proteostasis decline emerges earlier and correlates with functional impairment, suggesting it may be a primary driver of cellular senescence during physiological aging.

A Decline in Follicle Cell Function Is a Major Driver of Drosophila Ovarian Aging

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Aging drives a progressive accumulation of defects in somatic follicle cells of the Drosophila ovary. These defects are accompanied by reduced tissue and genome integrity, altered transcriptional profiles, and disrupted germ‐soma coordination. Targeted overexpression of Atg8a in a subset of follicle cells mitigates these defects and preserves ...

Exosomal Non‐Coding RNAs in Gastrointestinal Cancer Drug Resistance: A Systematic Review of Emerging Mechanisms and Clinical Implications

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT Gastrointestinal (GI) tumours are one of the most prevalent cancers globally. Even with normal GI function, individuals may develop neoplasms, highlighting the need to better understand the underlying causes of tumorigenesis. The emergence of tumour drug resistance represents the main reason for the failure of drug treatment; thus, it is ...

Ammonium chloride, an environmental pollutant, disrupts melanocyte biology through the regulation of melanosome and autophagy

open access: yesEcotoxicology and Environmental Safety
Ammonium chloride is an indoor environmental pollutant released due to industrial emissions, concrete, indoor bacteria, or other sources. In this study, we characterized molecular mechanisms of ammonium chloride-induced cell damage in melanocyte cells ...

Autophagy, physiology and cell pathology [PDF]

open access: yes, 2013
Autophagy plays an important role in human pathologies, such as myopathies and neurodegenerative diseases. Moreover, metabolic disease processes such as diabetes and pancreatitis, as well as tumor cells and cancer chemotherapy, activate autophagy ...

Cathepsin B-mediated autolysosome efflux and cell death [PDF]

open access: yes, 2010
Autophagy is a vesicular system which is a lysosomal degradation pathway found in organisms ranging from yeast to mammals. To date, extensive studies have unraveled the mechanism of autophagy biogenesis and more than thirty autophagy related (ATG) genes have been identified. However, detailed molecular mechanisms of autophagic process have not yet been
