Germ cells are essential for fertility, embryogenesis, and reproduction. Germline development requires distinct types of germ granules, which contains RNA-protein (RNP) complexes, including germ plasm in embryos, piRNA granules in gonadal germ cells, and the Balbiani body (Bb) in oocytes. However, the regulation of RNP assemblies in zebrafish germline development are still poorly understood.

Preserving fertility is important in men under radiation therapy because healthy cells are also affected by radiation. Supplementation with antioxidants is a controversial issue in this process. Designing a biocompatible delivery system containing hydrophobic antioxidants to release control may solve these disagreements.

Investigating intrauterine exposure to methamphetamine on serine-threonine kinase pathway in male rat testis.

Article Synopsis
  • Intrauterine exposure to methamphetamine (METH) during pregnancy negatively impacts testicular development in offspring, leading to apoptosis in spermatids.
  • Research focused on proteins involved in sperm growth pathways, particularly TSSK and RIPK2, showing significant changes in their expression levels due to METH exposure.
  • Findings indicated that METH exposure resulted in decreased TSSK expression, increased RIPK2 expression, thinner germ layers, more inflammatory cells, and a reduction in the thickness of seminiferous tubules in rat testes.

Female primordial germ cells (PGCs) undergo X chromosome reactivation (XCR) during genome-wide reprogramming. XCR kinetics and dynamics are poorly understood at a molecular level. Here, we apply single-cell RNA sequencing and chromatin profiling on germ cells from F mouse embryos, performing a precise appraisal of XCR spanning from migratory-stage PGCs to gonadal germ cells.
