Molecular mechanisms underlying the tumorigenesis of colorectal adenomas: correlation to activated K-ras oncogene.

Abstract excerpt

Mutations of K-ras gene have been demonstrated in 40-50% of colorectal cancer and large adenoma (>1 cm). This study was intended to clarify the correlation between the existence of K-ras oncogene and the pathological features of colorectal adenomas using our recently developed membrane arrays. Moreover, the downstream genes regulated by K-ras oncogene were explored to serve as potential biomarkers in the early...
