The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

open access: yesAdvanced Science, EarlyView.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Fosl2 Regulates FSH‐Dependent Follicle Maturation Through Feedback Amplification of FSH/FSHR Signaling

open access: yesAdvanced Science, EarlyView.
This study identifies a FOSL2‐driven positive feedback loop that amplifies FSH/FSHR signaling. During FSH‐dependent follicle maturation, FSH induces Fosl2 expression via the cAMP‐PKA‐CREB cascade. FOSL2 in turn binds the promoters of Fshr and estrogen‐biosynthesis genes to enhance their transcription, thereby increasing Fshr mRNA level and amplifying ...

A romatase enzyme inhibitor versus gonadotropin for induction of ovulation in patients with polycystic ovary syndrome resistant to clomiphene citrate a randomized controlled trial [PDF]

open access: yesMinia Journal of Medical Research, 2019
Introduction: Clomiphene citrate (CC) is the first drug used to induce ovulation in patients with poly cystic ovary syndrome (PCOS). Although 70–80% of such women ovulate when treated with CC, only 40% become pregnant (van Wely et al., 2005).

NET‐DNA Activates the ANXA2/TMEM215/BiP Axis to Promote Mitophagy‐Mediated Anoikis Resistance in Endometriosis

open access: yesAdvanced Science, EarlyView.
NET‐DNA is enriched during early endometriotic lesion establishment and drives anoikis resistance by promoting an ANXA2–TMEM215–BiP axis. This pathway strengthens ER–mitochondria contacts, enhances PINK1/Parkin‐associated mitophagy, preserves mitochondrial homeostasis, and supports ectopic stromal cell survival, thereby facilitating lesion persistence ...

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

open access: yesAdvanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

Equine models in translational medicine: A comparative approach to human health

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This diagram summarizes and contrasts rodent and equine models, outlining their strengths, limitations, and applications. Horses offer naturally occurring diseases, genetic and physiological similarities to humans, and suitability for longitudinal and clinical‐scale studies.

EVALUATION OF LETROZOLE THERAPEUTIC EFFECT IN INFERTILE WOMEN [PDF]

open access: yesActa Medica Iranica, 2007
Combination therapy with clomiphene citrate plus gonadotropin (clomiphene citrate plus HMG) in induction ovulation reduce the gonadotropins dose but antiestrogenic effect of c.c. can decrease pregnancy rate.

Microarray-based analysis of fish egg quality after natural or controlled ovulation

open access: yesBMC Genomics, 2007
Background The preservation of fish egg quality after ovulation-control protocols is a major issue for the development of specific biotechnological processes (e.g. nuclear transfer).

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Association of anti-mullerian hormone and free androgen index level on response to clomiphene citrate in PCOS infertile women

open access: yesGynecology and Obstetrics Clinical Medicine, 2022
Background: Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility. Clomiphene citrate, insulin-sensitizing drugs, aromatase inhibitors, gonadotropins, or laparoscopic ovarian drilling are various methods used for ovulation ...
