- Spermatogenesis is a highly regulated process leading to the development of functional spermatozoa through meiotic division and subsequent maturation. Recent studies have suggested that a novel class of Argonaute proteins, known as the PIWI clade, plays important roles in multiple stages of spermato

- Retinoic acid (RA) directs the sequential, but distinct, programs of spermatogonial differentiation and meiotic differentiation that are both essential for the generation of functional spermatozoa. These processes are functionally and temporally decoupled, as they occur in distinct cell types that a

- Besides its capacity to inhibit the 1,4,5-trisphosphate (IP3 ) receptor, the regulatory protein IRBIT (IP3 receptor binding protein released with IP3 ) is also able to control the activity of numerous ion channels and electrolyte transporters and thereby creates an optimal electrolyte composition of
