Is regulation of a LATS-homolog by Ras GTPases important for the control of cell division?
Dictyostelium discoideum NdrC is a LATS2-homologous kinase that is important for the regulation of cell division. NdrC contains a Ras-binding domain and interacts preferentially with RasB and RasG. Changed levels of both, RasB or RasG, have been shown previously to interfere with cell division. Since a defect in cell division is exhibited by NdrC-null cells, RasG-null cells, and cells overexpressing activated RasB, we propose a model for the regulation of cytokinesis by NdrC that involves the antagonistic control by RasB and RasG.
Males appear more susceptible than females to ifosfamide gonadotoxicity. There may be a dose in males below which the risk of subfertility is low. In females there is preliminary evidence of reduction in ovarian reserve as measured by AMH levels, which may potentially lead to an early menopause and a reduction in the window of fertility.
