Ectopic DEPTOR expression in two pancreatic cancer cell lines, Panc-1 and Miapaca-2, caused a significant 1) suppression of anchorage-dependent growth in monolayer culture, particularly under conditions with growth factor deprivation; 2) decreased clonogenic survival, and 3) suppressed anchorage-independent growth in soft agar. The gene discussed is DEPTOR; the disease is pancreatic neoplasm.
