HEP14 treatment improves ovarian function in aged mice through mitophagy enhancement and oxidative stress reduction.

ABSTRACT: Ovarian aging profoundly impacts reproductive health and accelerates the overall aging process, yet the development of effective therapeutic strategies remains a formidable challenge. In this study, we report the rejuvenating effects of HEP14, a natural activator of protein kinase C (PKC) pathway, on aged ovarian function by inducing mitophagy and effectively clearing reactive oxygen species. To ensure controlled and sustained delivery of HEP14 in vivo, we develop HEP14-loaded PLGA microspheres. Transcriptomic analysis reveals a significant overlap between the transcriptional profiles of HEP14-treated aged ovaries and those of adult ovaries, suggesting molecular rejuvenation process closely associated to HEP14-induced mitophagy. Histopathological evaluations further substantiate these find
