New insights into posttranslational modifications of proteins during bull sperm capacitation

Cell Communication and Signaling, 2023
Background Due to the unique nature of spermatozoa, which are transcriptionally and translationally silent, the regulation of capacitation is based on the formation of posttranslational modifications of proteins (PTMs).

Canine sperm motility is associated with telomere shortening and changes in expression of shelterin genes

BMC Veterinary Research, 2023
Background Motion quality is a critical property for essential functions. Several endogenous and exogenous factors are involved in sperm motility. Here, we measured the relative telomere length and evaluated the gene expression of its binding-proteins ...
