The expression of?-catenin in human colorectal cancer and its biological significance / 中国普通外科杂志

ABSTRACT

Objective To investigate the expression of ?-catenin protein in colorectal cancer. Methods Thirty-six CRC cases underwent radical operation from February 2001 to September 2001, ?-catenin protein expression was studied with immunnohistochemistry. ?-catenin mRNA expression was examined by reverse transcription-polymerase chain reaction (RT-PCR). The correlation between ?-catenin protein expression and CRC clinical pathological factors was studied. Results ?-catenin protein expression was positive in 30 CRC cases ( 83. 3% ) , and 2 cases ( 5. 6% ) in normal colorectal epithelium cells ( P
