-catenin pathway to promote the expression of genes essential for meiosis, such as and Rec8 . 3. Major Findings
While male germ cells (XY) undergo cell cycle arrest, female germ cells (XX) must exit the mitotic cycle (cloning themselves) and enter the meiotic cycle (preparing for fertilization). Signaling Cascade: RSPO1 acts through the 25641.rar
The study utilized mouse models to observe what happens when this signaling pathway is disrupted: Without sufficient RSPO1/ -catenin pathway to promote the expression of genes
-Catenin Signaling Pathway Regulates Oogonia Differentiation and Entry into Meiosis in the Mouse Fetal Ovary," explores the molecular triggers that cause early germ cells to become eggs (oocytes) rather than sperm. This differentiation is a critical "fork in the road" for sexual reproduction. 25641.rar
