The mRNA levels of mRNA for α1(IV), α4(IV), α6(IV) and α1(VII) collagens determined by real-time RT-PCR from healthy individuals (Normal), normal tissue from individuals with adenoma (Adenoma control), tissue from adenomas (Adenomas), normal tissue from colorectal cancer patients taken as far away from the carcinoma as possible from the surgically removed tissue (Normal distant), normal tissue from colorectal cancer patients taken near to the carcinoma (Normal adjacent) or colorectal cancer tissue (CRC). Each dot represents one individual. All mRNA levels were normalized to the level of β-actin mRNA.
