Detailed Description:
Primary sclerosing cholangitis (PSC) and colitis are chronic inflammatory disorders with malignant potential. Telomerase is an enzyme complex that lengthens telomeres and has enhanced expression in numerous malignancies. In this study, we evaluated the telomerase gene copy number, telomere length, cells in senescence, aneuploidy and additional parameters of telomere dysfunction from peripheral blood lymphocytes of patients.
