Mitochondrial dysfunction in cell senescence and aging

Journal of Clinical Investigation, 2022
Mitochondrial dysfunction and cell senescence are hallmarks of aging and are closely interconnected. Mitochondrial dysfunction, operationally defined as a decreased respiratory capacity per mitochondrion together with a decreased mitochondrial membrane ...

Amorphous silica biomineralizations in Schoenoplectus californicus (Cyperaceae): their relation with maturation stage and silica availability Biomineralizaciones de sílice amorfo en Schoenoplectus californicus (Cyperaceae): su relación con el estado...

Boletín de la Sociedad Argentina de Botánica, 2013
Summary: The factors involved on the silicification process in Cyperaceae are scarcely known. In this study we analyse the effect of maturation stage and silica availability on the production of amorphous silica biomineralizations in culms of ...

A new gene set identifies senescent cells and predicts senescence-associated pathways across tissues

Nature Communications, 2021
Although cellular senescence drives multiple age-related co-morbidities through the senescence-associated secretory phenotype, in vivo senescent cell identification remains challenging.

Remoción mecánica del material senescente para la recuperación de pasturas

Agronomía Mesoamericana, 2019
Introducción. La acumulación de material senescente en pasturas tropicales es resultado de la alta producción de biomasa y bajo nivel de aprovechamiento en pastoreo. La remoción de senescencia en pasturas permite que el ganado acceda a estratos bajos durante el pastoreo, lo que genera un rebrote con mayor concentración de nutrientes. Objetivo.

Mitochondrial DNA released by senescent tumor cells enhances PMN-MDSC-driven immunosuppression through the cGAS-STING pathway.

Immunity
Mitochondrial dysfunction is a hallmark of cellular senescence. Here, we investigated whether senescent cells release mitochondrial (mt)DNA into the extracellular space and its impact on innate immunity.
