Stress reduction through cortical bone thickening improves bone mechanical behavior in adult female Beclin-1+/− mice

Frontiers in Bioengineering and Biotechnology
Fragility fractures, which are more prevalent in women, may be significantly influenced by autophagy due to altered bone turnover. As an essential mediator of autophagy, Beclin-1 modulates bone homeostasis by regulating osteoclast and chondrocyte ...

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Muscle wasting in cancer cachexia: Mechanisms and the role of exercise

Experimental Physiology, EarlyView.
Abstract Cancer cachexia (CC) is a multifactorial disease marked by a severe and progressive loss of lean muscle mass and characterized further by inflammation and a negative energy/protein balance, ultimately leading to muscle atrophy and loss of muscle tissue.

One day of environment‐induced heat stress causes injury to the murine kidney

Experimental Physiology, EarlyView.
Abstract Environment‐induced heat stress (EIHS) results from sustained body temperature elevation owing to prolonged exposure to heat and humidity. We hypothesized that EIHS would cause kidney injury and cellular dysfunction. To test this hypothesis, female C57 mice were exposed to EIHS (n = 14; 37.6°C, 42.0% relative humidity) or thermoneutral (TN ...

Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

Baicalin Alleviates Lactational Heat‐Stress‐Induced Hepatic Mitochondrial Dysfunction via Sirt3‐Dependent Deacetylation of NDUFS1

Food Frontiers, Volume 7, Issue 6, November 2026.
This study reveals that lactational HS suppresses Sirt3 activity, leading to hyperacetylation of the complex I subunit NDUFS1, and excessive mitochondrial ROS production, whereas BAI, a nature food‐derived bioactive compound, alleviates lactational HS‐induced hepatic mitochondrial injury by activating the Sirt3–NDUFS1 axis to deacetylate mitochondrial ...

Lactate metabolism and protein lactylation in programmed cell death: From novel mechanism to therapeutic strategies in human diseases

Clinical and Translational Medicine, Volume 16, Issue 10, October 2026.
This review highlights protein lactylation as a metabolic‐epigenetic regulator linking lactate reprogramming to programmed cell death. By modulating histone and non‐histone targets, lactylation reshapes cell fate decisions and represents a promising biomarker and therapeutic target in human diseases.

Carotenoid‐Rich Pigment Extract From Micrococcus terreus SK34 Induces Apoptosis in SH‐SY5Y Neuroblastoma Cells: Integrated Metabolomic, Molecular Docking, and Experimental Validation

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Carotenoid extract from Micrococcus terreus SK34 was characterized by LC‐Q‐TOF‐MS and evaluated for its in vitro anticancer potential. The extract exhibited selective cytotoxicity against different cancer cell lines, particularly neuroblastoma cells (SH‐SY5Y), while sparing normal cells.

Characterization of apoptosis and autophagy through Bcl-2 and Beclin-1 immunoexpression in gestational trophoblastic disease

Iranian Journal of Reproductive Medicine, 2015
Background: The pathogenesis of Gestational Trophoblastic Disease (GTD) is not clearly known. Objective: In this study, immunoexpression of proteins Bcl-2 and Beclin-1 in trophoblastic lesions and normal trophoblastic tissue was conducted to study the ...

The Sleeping Giant: Metabolism and Autophagy in the Generation and Survival of Dormant Polyploid Giant Cancer Cells

MedComm, Volume 7, Issue 10, October 2026.
Polyploid giant cancer cells (PGCCs) arise in response to stress and play a critical role in therapy resistance and tumor dormancy. These cells can evade conventional treatments and later contribute to cancer relapse by generating progeny through nonmitotic, amitotic mechanisms.
