A Xanthine Derivative With Novel Heat Shock Protein 90‐Alpha Inhibitory and Senolytic Properties

Aging Cell, EarlyView.
This study aimed to find safe senolytic drugs that selectively eliminate senescent cells. Focusing on HSP90 inhibitors, we employed a virtual screening to identify novel, safer compounds (A). K5, a xanthinic candidate, effectively eliminated senescent cells in various cellular models (B), extended lifespan in flies, and reduced aging signs in mice (C).

Pyrroloquinoline Quinone Reprograms the Single‐Cell Landscape of Immune Aging in Hematopoietic Immune System

Aging Cell, EarlyView.
This study demonstrates that aging induces oxidative stress and inflammation in the hematopoietic immune system, resulting in immune homeostasis dysfunction, including alterations in B cells and hematopoietic stem cells, senescent cells (SnCs) accumulation, and senescence‐associated secretory phenotypes (SASPs) production. Notably, the study highlights

Studies with plant alpha-galactosidases

, 1976
The two molecular forms, I and II, of [alpha]-galactosidase from immature, mature (resting) and germinated vicia faba seeds have been studied. The enzymes have been purified by a multistage procedure and, in particular, the effect these stages have upon the relative isoenzyme levels has been investigated.

Senescent Macrophages Promote Age‐Related Revascularization Impairment by Increasing Antiangiogenic VEGF‐A165B Expression

Aging Cell, EarlyView.
The underlying mechanisms of age‐related revascularization impairment are not clear. Our research firstly identified that macrophages were more senescent in the ischemic skeletal muscle of old mice and senescent macrophages could inhibit revascularization.

Identifying PDAP1 as a Biological Target on Human Longevity: Integration of Mendelian Randomization, Cohort, and Cell Experiments Validation Study

Aging Cell, EarlyView.
Integration of multi‐omics analyses reveals PDAP1 as one of the key regulators of longevity and aging. Mendelian randomization, colocalization, prospective studies, and in vitro experiments highlight PDAP1's effects on mortality, lifespan, and cellular senescence.

Identification of Senomorphic miRNAs in Embryonic Progenitor and Adult Stem Cell‐Derived Extracellular Vesicles

Aging Cell, EarlyView.
A senomorphic miRNA cocktail (E5), consisting of miR‐181a‐5p, miR‐92a‐3p, miR‐21‐5p, and miR‐186‐5p, was identified from a pool of miRNAs enriched in extracellular vesicles (EVs) derived from multiple functional human stem cell types. E5 reduces senescence and SASP markers both in cell culture and in aged mice.

TLR7 Mediates HIV‐1 Tat‐Induced Cellular Senescence in Human Astrocytes

Aging Cell, EarlyView.
Once internalized into endolysosomes, HIV‐1 Tat interacts and activates TLR7, causing endolysosome damage. Such interaction between HIV‐1 Tat and TLR7 also leads to a senescence‐like phenotype in astrocytes, including cell cycle arrest, elevated levels of p21 and p16 proteins, increased SA‐β‐gal activity, and enhanced secretion of SASP factors ...

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 ...
