Periodic production of retinoic acid by meiotic and somatic cells coordinates four transitions in mouse spermatogenesis by Endo, Tsutomu, Freinkman, Elizaveta, de Rooij, Dirk G., Page, David C

“…We conclude that the premeiotic transitions are coordinated by RA from Sertoli (somatic) cells. Once germ cells enter meiosis, pachytene spermatocytes produce RA to coordinate the two postmeiotic transitions. …”

Identification, characterization and metagenome analysis of oocyte-specific genes organized in clusters in the mouse genome by Vaiman Daniel, Dalbiès-Tran Rozenn, Bontoux Martine, Callebaut Isabelle, Dadé Sébastien, Paillisson Amélie, Monget Philippe

“…</p> <p>Conclusion</p> <p>We have studied five clusters of genes specifically expressed in female, some of them being also expressed in male germ-cells. Moreover, contrarily to non-clustered oocyte-specific genes, those that are organized in clusters tend to map near chromosome ends, suggesting that this specific near-telomere position of oocyte-clusters in rodents could constitute an evolutionary advantage. …”

Catalase T-Deficient Fission Yeast Meiocytes Show Resistance to Ionizing Radiation by Razan Muhtadi, Alexander Lorenz, Samantha J. Mpaulo, Christian Siebenwirth, Harry Scherthan

“…DNA damage and its faulty repair can lead to cell death or promote cancer through the accumulation of mutations. Misrepair in germ cells is particularly dangerous as it may lead to alterations in developmental programs and genetic disease in the offspring. …”

Maternal exposure to genistein during pregnancy and oxidative DNA damage in testes of male mouse offspring by Roger W. L. Godschalk, Margit C. M. Janssen, Kimberly Vanhees, Sahar Barjesteh van Waalwijk van Doorn-Khosrovani, Frederik-Jan van Schooten

“…Therefore, high intake of genistein during pregnancy may have adverse effects on the genetic integrity of testes and germ cells of male offspring. In this study, we examined whether maternal exposure to genistein during pregnancy induced oxidative DNA damage in the male germline at adolescence.MethodsAtm-ΔSRI mice have lower glucose-6-phosphate dehydrogenase (G6PDH) activity, which is important for maintaining levels of reduced glutathione and therefore these mice have an increased susceptibility to oxidative stress. …”

Seasonal expression of androgen receptor, aromatase, and estrogen receptor alpha and beta in the testis of the wild ground squirrel (Citellus dauricus Brandt) by Q. Li, F. Zhang, S. Zhang, X. Sheng, X. Han, Q. Weng, Z. Yuan

“…AR was present in Leydig cells, peritubular myoid cells and Sertoli cells in the breeding season and pre-hibernation with more intense staining in the breeding season, whereas AR was only found in Leydig cells in the nonbreeding season; P450arom was expressed in Leydig cells, Sertoli cells and germ cells during the breeding season, whereas P450arom was found in Leydig cells and Sertoli cells during pre-hibernation, but P450arom was not present in the nonbreeding season; stronger immunohistochemical signal for ERα was present in Sertoli cells and Leydig cells during the breeding season; ERβ was only expressed in Leydig cells of the breeding season. …”
