摘要: Extracellular signal-related kinase (ERK) and c-Jun N-terminal (JNK) mitogenactivated protein (MAP) kinases are highly activated in an vivo rat model of colorectal carcinogenesis. In addition, other such as c-Src c-Yes have been shown to be up-regulated some human colon cancers. To evaluate the activity these carcinomas, we examined cancers adjacent normal intestinal mucosa from 11 patients. Moderate increases ERK JNK activities, addition up-regulation c-Src, p125FAK, tyrosine-phosphorylated proteins, were observed a subset carcinomas. There was significant correlation found between levels well activity. This is first report that examines several different markers characterize same carcinoma sample, allowing determination correlations tumors.
