TGFBR2 and uterine cervix carcinoma in situ: The Spearman correlation coefficient (r) for TGFBR2 and hTERT expression in normal, CIN-I, CIN-II, CIN-III and cancer samples was −0.734 (P = 0.01), −0.232 (P = 0.10), 0.391 (P = 0.10), 0.512 (P = 0.01), −0.120 (P = 0.13), respectively, indicating that the correlation between TGFBR2 and hTERT is distinct at different periods of progression of cervical cancer (Tables 6 and 7).
