Hydroxychloroquine alleviates cyclophosphamide-induced premature ovarian failure by attenuating granulosa cell senescence and modulating the mtDNA-cGAS pathway

2 weeks ago
Cyclophosphamide (CTX) is a first-line chemotherapeutic agent for various cancers but is associated with a significant risk of ovarian dysfunction, which may even progress to premature ovarian failure (POF). Granulosa cell senescence is a key phenotypic manifestation of this process. Hydroxychloroquine (HCQ) exerts anti-senescence effects in age-related diseases; however, its efficacy in preventing CTX-induced ovarian damage remains elusive. We aimed to verify the protective effect of HCQ using...

Cycloneolitsol prolongs the lifespan of Caenorhabditis elegans by SEK-1/PMK-1/SKN-1 pathway and exerts anti-inflammatory effects by NF-kappaB pathway

2 weeks ago
Aging is a major risk factor for the onset and progression of many neurodegenerative diseases. Inflammation is the body's natural defense mechanism against harmful stimuli. A growing body of research has highlighted the intricate relationship between aging and inflammation, with chronic low-grade inflammation, often referred to as "inflammaging," being a hallmark of the aging process. Cycloneolitsol (CL) is a C-32 cycloartane-type triterpene from Taxodium ascendens which has been reported to...

Effect of Obstructive Sleep Apnea and CPAP on Telomere Length and Its Associated Mechanisms: A Pilot Study

2 weeks ago
The present study aimed to investigate the effect of obstructive sleep apnea (OSA) and its treatment with continuous positive airway pressure (CPAP), the gold standard treatment for OSA on changes of telomere length and its associated mechanisms. In this mechanistic pilot study of a selective patient population (middle-aged men, BMI < 35 kg/m², moderate-severe OSA), a 6-month randomized, double-blind, and sham-controlled clinical trial was conducted (Clinical Trials: NCT04872816, April 29, 2021...
