Reduced retinoids and retinoid receptors' expression in pancreatic cancer: A link to patient survival.

abstract：:The Ki-ras proto-oncogene is activated by specific point mutations and is the transforming gene often identified in rodent and human lung tumors. An in vitro model to aid in the study of the consequences of Ki-ras activation and expression in mouse lung is needed. Accordingly, we have examined cell lines derived from ...
