The mechanistic target of rapamycin signaling pathway
UNLABELLED: Heat stress significantly disrupts physiological and molecular balance in poultry, leading to oxidative damage, inflammatory responses, and metabolic dysregulation. Among emerging solutions, phytogenic adaptogens have shown promise as natural agents that enhance resilience against …
Acute-on-chronic liver failure (ACLF) is a severe liver syndrome marked by systemic inflammation and high mortality, often complicated by autophagy impairment and mitochondrial dysfunction. This study investigates atractylenolide I (AT-1), a compound from Atractylodes macrocephala, …
Researchers mapped the proteins in immortal jellyfish (Turritopsis) that detect environmental stress and decide whether to stay dormant or regenerate. They identified a three-layer signaling architecture centered on mTORC1—a key aging pathway—that could offer clues …
Reactive oxygen species (ROS) are essential second-messenger molecules, yet when deregulated, they fuel cancer growth and therapeutic resistance. In high-grade gliomas, including glioblastoma, diffuse hemispheric glioma, and diffuse midline glioma (DMG), genetic, epigenetic, and metabolic …
Researchers found that a protein called Dicer-1 in fat tissue acts as a master regulator of aging in fruit flies by controlling insulin levels throughout the body. When Dicer-1 is reduced, it triggers a chain …
Researchers built a computer simulation of how aging works in the body and tested which combination of four existing drugs (semaglutide, SGLT2 inhibitors, metformin, and rapamycin) might slow aging most effectively. The model suggests that …
AIMS: Numerous preclinical studies suggested that targeted inhibition of mammalian target of rapamycin (mTOR) may be beneficial for the treatment of osteoporosis. However, the relevance of these findings to human populations remains unclear. We hypothesized …
Dedifferentiated liposarcoma is a rare mesenchymal malignancy driven by amplification of chromosome 12q13-15, which includes the oncogenes CDK4 and MDM2. CDK4 amplification provides a rationale for targeted therapy with CDK4/6 inhibitors, and abemaciclib has shown …
Ovarian aging is characterized by progressive follicular reserve depletion, mitochondrial dysfunction, oxidative stress, and endocrine decline. This review examines the molecular mechanisms driving ovarian aging and evaluates emerging therapeutic strategies to preserve reproductive longevity. Key …
Researchers found that a protein called pitp-1 acts as a brake on longevity by activating mTOR signaling—a key aging pathway. Disabling pitp-1 in neurons extended lifespan, improved muscle function, and boosted stress resistance in C. …
Cellular metabolism is precisely regulated in response to nutrient availability. As an extremely energy-consuming anabolic process, ribosome biogenesis should be tightly controlled in response to nutrient supply. However, how the nucleolus responds to different nutrient …
Researchers found that Dendrobium officinale, a traditional longevity herb, extended lifespan in yeast and fruit flies by modulating a key aging-control pathway called PI3K-AKT. Different parts of the plant worked in opposite ways depending on …
Biallelic pathogenic variants in STRADA (STE20-related adaptor alpha), an upstream regulator of the mechanistic target of rapamycin (mTOR) pathway, result in megalencephaly, drug-resistant epilepsy, and severe intellectual disability. This study explores how mTOR pathway hyperactivity …
Researchers gave aging mice rapamycin and found it prevented the normal decline in movement and motor control, with females benefiting more than males. The benefits appear linked to reduced oxidative stress and cellular stress in …
BackgroundGeroprotective interventions, including the mTOR inhibitor rapamycin, slow aging in preclinical models. Translation to humans remains challenging because clinical trials require endpoints detectable within feasible timeframes. Multi-modal in vivo imaging could address this limitation by …
Despite optimal lipid-lowering treatment, numerous older adults with atherosclerotic cardiovascular disease continue to experience progression driven by inflammation, referred to as residual inflammatory risk. Cellular senescence and the senescence-associated secretory phenotype (SASP) significantly contribute to …
Geroscience has the goal of extending lifespan through geroprotective interventions. These interventions are typically imparted on groups of individuals, with their efficacy judged by increases in the average age-at-death. A more equitable outcome, which looks …
BACKGROUND: Acupuncture may alleviate both the motor and depressive symptoms of Parkinson's disease (PD); however, the underlying mechanism has not yet been elucidated. In this study, on the basis of previous findings that acupuncture improves …
The prevalence of major depressive disorder (MDD) is increasing globally, particularly among adolescents. Although gut-brain axis dysfunction has been implicated in adolescent depression, the mechanisms by which gut microbiota dysbiosis drives depressive behaviors and potential …
Almost a century ago, calorie restriction (CR) was identified as a robust intervention for extending lifespan and healthspan, a discovery that captured the imagination of both scientists and the public. If the powerful mechanisms engaged …
