Loss of ADAM29 does not affect viability and fertility in mice but improves wound healing.

ADAM29 (a disintegrin and metalloprotease domain 29) is a member of the membrane-anchored ADAM family of proteins, which is highly expressed in testis and may mediate different physiological and pathological processes. Although the functions of many ADAM family members have been well characterized, the biological relevance of ADAM29 has remained largely unknown. Here, we report the generation of an -deficient mouse model to delve deeper into the functions of this ADAM family member.

Noncoding RNA Contribution to Aging and Lifespan.

Aging is a multifactorial process characterized by an age-related decline in organismal fitness. This deterioration is the major risk factor for chronic diseases such as cardiovascular pathologies, neurodegeneration, or cancer, and it represents one of the main challenges of modern society. Therefore, understanding why and how we age would be a fundamental pillar to design strategies to promote a healthy aging.

Assessing microbiota composition in the context of aging.

The gut microbiota is a complex community of different microbial species that influence many aspects of health. Consequently, shifts in the composition of gut microbiome have been proposed to exert negative effects on the host physiology, leading to the pathogenesis of various age-related disorders, including cardiovascular and neurological diseases, type 2 diabetes, obesity, non-alcoholic liver disease, and other pathological conditions. Thus, understanding how the gut microbiota influences the aging-related decline is particularly topical.

The hallmarks of aging as a conceptual framework for health and longevity research.

The inexorability of the aging process has sparked the curiosity of human beings since ancient times. However, despite this interest and the extraordinary scientific advances in the field, the complexity of the process has hampered its comprehension. In this context, The Hallmarks of Aging were defined in 2013 with the aim of establishing an organized, systematic and integrative view of this topic, which would serve as a conceptual framework for aging research.

USP49 deubiquitinase regulates the mitotic spindle checkpoint and prevents aneuploidy.

The spindle assembly checkpoint (SAC) is an essential mechanism that ensures the accurate chromosome segregation during mitosis, thus preventing genomic instability. Deubiquitinases have emerged as key regulators of the SAC, mainly by determining the fate of proteins during cell cycle progression. Here, we identify USP49 deubiquitinase as a novel regulator of the spindle checkpoint.
