TFEB Orchestrates Stress Recovery and Paves the Way for Senescence Induction in Human Dermal Fibroblasts

Aging Cell, EarlyView.
TFEB dynamics during oxidative stress‐induced premature senescence. The tBHP treatment undermines GSH‐dependent antioxidant mechanisms, leading to increased ROS production and lysosomal damage. In the stress phase, we observed the concomitant inhibition of Akt along with activation of AMPK, together leading to mTOR inhibition and subsequent ...

Nuclear Import Defects Drive Cell Cycle Dysregulation in Neurodegeneration

Aging Cell, EarlyView.
Overview of Dysregulated Cell Cycle Mechanisms in Neuronal Cells. A nuclear import block drives cell cycle re‐entry from G0, culminating in cell cycle arrest at G1/S. This cell cycle arrest is associated with activation of CKIs from the INK locus (p15, p16, p18, p19) and Cip/Kip (p21, p27) which act on specific CDK/Cyclin complexes.

DLK/JNK3 Upregulation Aggravates Hair Cell Senescence in Mice Cochleae via Excessive Autophagy

Aging Cell, EarlyView.
In normal physiological processes, autophagy acts as a protective factor against aging stress. With the stress increase, the DLK/JNK3 pathway is activated and autophagy is continuously upregulated. In our study, excessive autophagy leads to hair cell senescence, which reveals that excessive autophagy can play a harmful role in senescence under certain ...

hTERT Increases TRF2 to Induce Telomere Compaction and Extend Cell Replicative Lifespan

Aging Cell, EarlyView.
In contrast to the dogma that a subset of short telomeres initiates senescence, hTERT variants unable to maintain telomere length block senescence by stabilizing TRF2 via inhibiting upstream E3 ubiquitin ligases. This noncanonical hTERT function also compacts telomeres and blocks senescence‐associated DNA damage signaling. Cancer cells expressing hTERT

Intermittent Supplementation With Fisetin Improves Physical Function and Decreases Cellular Senescence in Skeletal Muscle With Aging: A Comparison to Genetic Clearance of Senescent Cells and Synthetic Senolytic Approaches

Aging Cell, EarlyView.
Supplementation with the natural senolytic agent fisetin attenuated age‐related declines in physical function in mice. Better physical function with fisetin was accompanied by lower expression of cell senescence‐related genes. Fisetin treatment had comparable effects on physical function as genetic clearance of senescent cells and synthetic senolytic ...

Dexrazoxane protects against doxorubicin‐induced cardiotoxicity in susceptible human living myocardial slices: A proof‐of‐concept study

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose The increasing number of cancer survivors has caused growing concern over chemotherapy‐induced cardiotoxicity. This study aimed to investigate a novel human model of cardiotoxicity and explore cardioprotection. Experimental Approach Living myocardial slices (LMS) were obtained from explanted end‐stage heart failure ...

HN1 Functions in Protein Synthesis Regulation via mTOR‐RPS6 Axis and Maintains Nucleolar Integrity

Cell Proliferation, EarlyView.
HN1 is required for nucleolar homeostasis which is the site of ribosome biogenesis and protein synthesis when its mRNA is knocked down by shRNA, it depletes in cytoplasm and the protein synthesis is downregulated in comparison to controls. Thus, the proliferating cells requiring vast number of nucleosomes, are arrested at S onset.

Mechanotransduction Mediated by PDLIM5: The Critical Role of Serpin E2/Integrin β3‐Cytoskeleton‐Nucleoskeleton Axis in Mechanical Osteogenic Programming

Cell Proliferation, EarlyView.
Large segmental bone defects can result in non‐union of fractures and present a formidable challenge in clinical management. This study aims to investigate the role of mechanical stimulation in regulating osteogenic differentiation of stem cells via the mechanosensitive protein PDLIM5, thereby promoting bone regeneration and repair.

Chromosomal localization of PHOX2B during M‐phase is disrupted in disease‐associated mutants

Development, Growth &Differentiation, Volume 67, Issue 3, Page 136-148, April 2025.
Some transcription factors exhibit chromosomal localization during M‐phase and play an important role in the rapid re‐activation of target genes in early G1‐phase. In this study, we assessed the chromosomal localization of Paired‐like homeodomain 2B (PHOX2B) and its disease‐associated mutants, and found that disease‐associated PHOX2B mutants exhibited ...

The cerebellum in epilepsy

Epilepsia, EarlyView.
Abstract The cerebellum, a subcortical structure, is traditionally linked to sensorimotor integration and coordination, although its role in cognition and affective behavior, as well as epilepsy, is increasingly recognized. Cerebellar dysfunction in patients with epilepsy can result from genetic disorders, antiseizure medications, seizures, and seizure‐
