Species difference in the expression of Fas and Fas ligand in mature mammalian spermatozoa

Czech Journal of Animal Science, 2017
Although it has been proposed that the Fas and Fas ligand (FasL) may protect ejaculated spermatozoa against apoptosis induced by lipoperoxidative damage and against lymphocytes present in the female genital tract, studies reported conflicting results on ...

Tuning the Testicular Microenvironment for Enhancing Human Sertoli Cells Maturation and Functionality In Vitro

Advanced Healthcare Materials, EarlyView.
An in vitro testicular model is developed by generating connective tissue equivalents from human dermal fibroblast‐derived microtissues and coupling them with human Sertoli cells or human Sertoli cell spheroids. This engineered microenvironment supports Sertoli cell maturation and functionality, providing a promising platform for studying human ...

Role of oxidative stress and antioxidants in domestic and non-domestic cat spermatozoa [PDF]

, 2010
Living cells, including spermatozoa, stored under aerobic conditions require oxygen to support their normal metabolism. Excessive levels of metabolites (reactive oxygen species; ROS) can cause cell damage or lipid peroxidation.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...
