Few therapeutic options are available to treat COVID-19. The KEAP1/NRF2 pathway, the major redox-responsive pathway, has emerged as a potential therapeutic target for COVID-19 as it regulates redox homeostasis and inflammation that are altered during SARS-CoV-2 infection. Here, we characterized the effects of NRF2-agonist Sulfodyne, a stabilized natural Sulforaphane, in cellular and animal models of SARS-CoV-2 infection.

Background: Human multilineage-differentiating stress enduring (Muse) cells are nontumorigenic endogenous pluripotent-like stem cells that can be easily obtained from various adult or fetal tissues. Regenerative effects of Muse cells have been shown in some disease models. Muse cells specifically home in damaged tissues where they exert pleiotropic effects.

The generation of oocytes from induced pluripotent stem cells (iPSCs) was proven efficient with mouse cells. However, no human iPSCs have yet been reported to generate cells able to complete oogenesis. Additionally, efficient sorting of human Primordial Germ Cell- Cells (hPGC-LCs) without genomic integration of fluorescent reporter for their downstream manipulation is still lacking.

Article Synopsis
  • Many endocrine disruptors, like Bisphenol A (BPA), negatively affect meiosis, a process crucial for healthy gamete production, leading to conditions like oocyte aneuploidy.
  • Research on BPA alternatives, such as BADGE and BPAF, reveals they also delay meiosis, increase specific foci in cells, and cause defects in gene expression and DNA integrity during oogenesis in mice.
  • The study suggests that oxidative DNA damage may be a common harmful mechanism in female meiosis caused by various environmental pollutants, highlighting the need to reevaluate the risks of mixtures of bisphenols found in our surroundings.

Male gametogenesis involves both mitotic divisions to amplify germ cell progenitors that gradually differentiate and meiotic divisions. Centrosomal regulation is essential for both types of divisions, with centrioles remaining tightly paired during the interphase. Here, we generated and characterized the phenotype of mutant mice devoid of , a gene encoding for a docking protein for fibers linking centrioles, and characterized their phenotype.
