Busulfan administration replicated the characteristics of the epididymal initial segment observed in mice lacking testis-epididymis lumicrine signaling

open access: yesThe Journal of Reproduction and Development
The physiological functions of the mammalian epididymis are typically regulated by the testes. In addition to sex steroids secreted by testicular Leydig cells, which act on the epididymis in an endocrine manner, there is a non-sex-steroidal signaling ...

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 ...

Selenium‐Based Nanoplatforms: An Emerging Theranostic Paradigm for Gynecological Cancers

open access: yesAdvanced Science, EarlyView.
This reivew summarizes Selenium as a multifunctional anticancer regulator in gynecological cancers. It reduces tumor risk, enhances therapeutic efficacy, and reduces treatment toxicity. Selenium also overcomes chemoraditherapy resistance, improving overall treatment outcomes. ABSTRACT Gynecological cancers present significant therapeutic challenges due

Mitochondrial Functionality in Male Fertility: From Spermatogenesis to Fertilization

open access: yesAntioxidants, 2021
Mitochondria are structurally and functionally distinct organelles that produce adenosine triphosphate (ATP) through oxidative phosphorylation (OXPHOS), to provide energy to spermatozoa. They can also produce reactive oxidation species (ROS).
