Abstract:
Objective To explore relationship between telomerase and canceration of colorectal adenoma.Methods Telomerase activity was measured by hybridization-in-situ in 30 colorectal adenoma,30 normal colorectal mucosa ,30 colorectal adenoma canceration tissues and normal close adenoma.Results The expression of telomerase in colorectal adenoma canceration was 86.6%(strong positive 73.3%, weak positive 13.3%);60% in close adenoma tissues(strong positive 6.7%, weak positive 53.3%),10% in normal colorectal adenoma(strong positive 3.3%, weak positive6.7%),0% in normal colorectal mucosa.Conclusions Telomerase plays a critical role in colorectal adenoma canceration and is a internal factor.It is a sign of canceration tendency(not malignant transformation) in canceration.
