As unhealthy aging continues to rise globally, there is a pressing need for effective strategies to promote healthy aging, extend health span, and address aging-related complications. Gerobiotics, an emerging concept in geroscience, offers a novel approach to repurposing selective probiotics, postbiotics, and parabiotics to modulate key aging processes and enhance systemic health. This review explores recent advancements in gerobiotics research, focusing on their role in targeting aging hallmarks, regulating longevity-associated pathways, and reducing risks of multiple age-related chronic conditions. Despite their promise, significant challenges remain, including optimizing formulations, ensuring safety and efficacy across diverse populations, and achieving successful clinical translation. Addressing these gaps through rigorous research, well-designed clinical trials, and advanced biotechnologies can establish gerobiotics as a transformative intervention for healthy aging and chronic disease prevention.

Hemophilia is a rare X-linked bleeding disorder caused by mutations in the F8 or F9 gene (hemophilia A or B), leading to deficient factor VIII or IX proteins, respectively. Hemophilia-related complications caused by bleeding into the joints (the hallmark of hemophilia) and age-related comorbidities occur frequently and impact the functionality and quality of life of persons with hemophilia (PwH). Given the chronic nature of hemophilia, we hypothesized that hemophilia has an association with accelerated biological aging.

In recent years, evidence of the existence of cellular senescence in the central nervous system has accumulated. In ischemic stroke, cellular senescence has been suggested as an unidentified pathophysiological mechanism, prompting research into the neuroprotective potential of senolytic drugs. This study aims to provide spatio-temporal evidence of the existence of brain senescence following ischemic stroke and to elucidate the involved pathways and cell types.

Chronic intermittent hypoxia (IH) is one of the hallmark features of obstructive sleep apnea (OSA) and adversely affects neurocognitive and behavioral functioning. However, how the duration of IH correlates with its deleterious effects remains unexplored. We aimed to assess the effects of IH over a prolonged period of time mimicking untreated OSA.

Reduced bone mass and density, hallmark features of osteopenia and osteoporosis, significantly increase the risk of fractures, falls, and loss of mobility, especially in post-menopausal women and the elderly. This quantitative 7T MRI study examines the features of fibular bone thinning and bone mineral density loss (BMD) in 107 individuals (43F/64M) across various ages, body mass indices (BMIs), and ethnicities. Women had significantly lower cross-sectional bone wall thickness (BT) and bone tissue area (BA), along with greater BMD loss compared to men in those over age 50 ( = 77), but not in the younger group ( = 30).

The accurate control of DNA replication is crucial for the maintenance of genomic stability and cell viability. In this study, we explore the consequences of depleting the replicative DNA Polymerase α (POLA) in the wing disc of Drosophila melanogaster. Our findings reveal that reduced POLA activity induces DNA replication stress and activates the replication checkpoint in vivo.
