Does l-3-Phosphoserine phosphatase ( PSPH ) regulate cutaneous squamous cell carcinoma proliferation independent of L-serine biosynthesis?
Psph is highly induced in proliferative normal keratinocytes and in skin tumors. PSPH appears to be critical for the proliferation of SCC cells; however, this phenomenon may not involve the phosphoserine metabolic pathway.
Patients found sonographically to be a breech presentation at 25 weeks' gestation or later are at high risk for malpresentation at delivery.
