Hypomethylation‐Triggered SERPINE1 (Serpin Family E Member 1) Exacerbates Polycystic Ovary Syndrome with Hyperandrogenism Induced by Circadian Disruption

open access: yesMedComm, Volume 6, Issue 7, July 2025.
SERPINE1 shows CpG hypomethylation near its TSS of promoter region when exposed to circadian disruption, and its gene expression triggers hyperandrogenism through the PI3K/AKT pathway. SERPINE1 inhibitor TPX can significantly decrease serum SERPINE1 levels and reduce abnormally high testosterone levels in both continuous darkness‐exposed rats and DHEA ...

The effect of morning or evening fasted cycling on gastrointestinal function and appetite and metabolic responses in healthy males with overweight

open access: yesExperimental Physiology, Volume 110, Issue 7, Page 961-975, 1 July 2025.
Abstract Combining fasting with exercise may influence gastric emptying rate (GER) and provide benefits to weight management and metabolic health. Furthermore, the time of day in which exercise is performed may also influence these variables. The aim was to investigate if fasting or fed exercise at different times of the day would alter GER, appetite ...
