Activating mutation of the Kras oncogene is the most frequent and perhaps the earliest genetic alteration associated with pancreatic cancer. To examine the link between mutant Kras and exocrine pancreatic cancer, we generated transgenic mice carrying an elastase-mutant Kras transgene, which targets expression to pancreatic acinar cells.

A longitudinal model of parent academic involvement, behavioral problems, achievement, and aspirations was examined for 463 adolescents, followed from 7th (approximately 12 years old) through 11th (approximately 16 years old) grades. Parent academic involvement in 7th grade was negatively related to 8th-grade behavioral problems and positively related to(More)
Mice carrying two or more transgenes are used frequently to evaluate oncogene interactions during carcinogenesis. However, neoplastic transformation typically results in reduced expression both of differentiation-specific genes and of transgenes that use their promoters. In contrast, the more widely expressed metallothionein (MT) gene remains expressed at a(More)
