Small cell size preserves the function of hematopoietic stem cells (HSCs); HSC enlargement during aging causes their dysfunction.
Late-life-initiated dietary interventions show limited efficacy in extending longevity or mitigating frailty, yet the underlying causes remain unclear. Here we studied age-related fasting response of short-lived killifish Nothobranchius furzeri. Transcriptomic analysis uncovered existence a fasting-like transcriptional program adipose tissue old fish that overrides feeding response, setting persistent metabolic quiescence. The fasting-refeeding cycle triggers an inverse oscillatory...
The advent of molecularly targeted therapeutic agents has opened a new era in cancer therapy. However, many tumors rely on nondruggable cancer-driving lesions. In addition, long-lasting clinical benefits from single-agent therapies rarely occur, as most the acquire resistance over time. identification combination regimens interfering with signaling through oncogenically rewired pathways provides promising approach to enhance efficacy single-agent-targeted treatments. Moreover, drug might...
Abstract Objective We describe a family with novel mutation in the TNF Receptor Superfamily Member 1A (TNFRSF1A) gene causing receptor–associated periodic syndrome (TRAPS) renal AA amyloidosis. Methods Case series of affected members. further investigated plasma metabolome these patients comparison healthy controls using mass spectrometry. Results In all symptomatic members, we detected previously undescribed variant c.332A>G (p.Q111R) TNFRSF1A gene. Canakinumab proved an effective...
Abstract Stem cells are remarkably small in size. Whether size is important for stem cell function unknown. We find that murine hematopoietic (HSCs) enlarge under conditions known to decrease function. This decreased fitness of large HSCs due reduced proliferative potential. Preventing HSC enlargement by inhibiting macromolecule biosynthesis or reducing shortening G 1 averts the loss potential causing exhaustion. Finally, we show a fraction and human during aging. this age-dependent improves...
Abstract The cGAS/STING pathway is a central innate immune signaling whose chronic activation has been implicated in numerous age-related pathologies, yet its impact on life span itself unknown. Here we engineered knockouts of this the killifish Nothobranchius furzeri , and assessed physiology aging. In vitro loss cGAS or STING mitigated DNA damage-induced senescence cultured fibroblasts. vivo knockout unexpectedly led to low-grade inflammation. It also attenuated changes gene expression...
Abstract Caloric Restriction (CR) extends lifespan and augments cellular stress-resistance from yeast to primates, making CR an attractive strategy for organ protection in the clinic. Translation of patients is complex, due problems regarding adherence, feasibility safety concerns frail patients. Novel tailored dietary regimens, which modulate composition macro- micronutrients rather than reducing calorie intake promise similar protective effects increased translatability. However, a direct...
