Hutchinson-Gilford Progeria Syndrome (HGPS) is a fatal genetic disorder caused by progerin, a mutant lamin A variant that disrupts nuclear architecture and drives systemic cellular dysfunction. Gastrointestinal (GI) involvement in HGPS remains poorly understood, despite growing evidence of gut abnormalities and microbial dysbiosis in progeroid mouse models. Here, we provide the first comprehensive characterization of colonic pathology in Lmna^(G609G/G609G) mice and assess the therapeutic impact...

The advent of in vivo reprogramming through transient expression of the Yamanaka factors (OCT4, SOX2, KLF4, and c-MYC) holds strong promise for regenerative medicine, despite ongoing concerns about safety and clinical applicability. This review synthesizes recent advances in in vivo reprogramming, focusing on its potential to restore regenerative competence and promote rejuvenation across diverse tissues, including the retina, skeletal muscle, heart, liver, brain, and intestine. We highlight...

CONCLUSIONS AND IMPLICATIONS: This review and meta-analysis support that exercise training is an effective model of improving frailty levels among older adults in long-term care. Strategies to address the practical aspects of these programs are needed, but this study emphasizes that structured exercise should be a crucial aspect of long-term care.

CONCLUSIONS AND IMPLICATIONS: Our findings highlight the clinical importance of recognizing fatigue throughout the entire aging life span as an independent marker for subsequent negative health outcomes and mortality. Although fatigue might serve as a surrogate for intrinsic capacity, it remains unclear if fatigue is amenable to intervention.
