Advanced Science, EarlyView.In this study, we provided new evidence identifying multinucleated cysts as precursors for oocyte differentiation. Within these cysts, organelles migrate and aggregate to form Balbiani body (B‐body) and establish early cellular polarity. Concurrently, excess nuclei are expelled, enabling cyst‐to‐oocyte differentiation. The microfilament‐myosin II plays

A bioengineered in situ ovary (ISO) supports follicle engraftment and live-births post-chemotherapy
Journal of Tissue Engineering, 2023 Female cancer patients who have undergone chemotherapy have an elevated risk of developing ovarian dysfunction and failure. Experimental approaches to treat iatrogenic infertility are evolving rapidly; however, challenges and risks remain that hinder ...

Advanced Science, EarlyView.This study uncovers a novel mechanism in which p300‑catalyzed lactylation of HMGB1 triggers nuclear export of the HMGB1‐TIAR complex, driving TIAR‐dependent SGs formation in the cytoplasm. Mass spectrometry and mutagenesis reveals that K177 lactylation is essential for this export and subsequent SGs formation.

Advances in methods for determining fecundity: application of the new methods to some marine fishes [PDF]
, 2009 Estimation of individual egg production (realized fecundity) is a key step either to understand the stock and recruit relationship or to carry out fisheries-independent assessment of spawning stock biomass using egg production methods.

Use of Urinary Pregnanediol 3-glucuronide to Confirm Ovulation [PDF]
, 2013 Objective Urinary hormonal markers may assist in increasing the efficacy of Fertility Awareness Based Methods (FABM). This study uses urinary pregnanediol-3a-glucuronide (PDG) testing to more accurately identify the infertile phase of the menstrual cycle

Advanced Science, EarlyView.1) 14, 15‐EET levels were decreased in ovarian granulosa cells, follicular fluid, peritoneal fluid from endometriosis patients. 2) EETs reduction in endometriosis follicular fluid aggravated granulosa cell senescence. 3) ROS reduced 14, 15‐EET levels by upregulating EPHX2 through a mechanism involving histone methylation modification.
