From: Regulatory effects of COL1A1 on apoptosis induced by radiation in cervical cancer cells
The expression of COL1A1 in cervical normal and cancer tissues. a COL1A1 was detected significantly increased in cervical cancer tissues (n = 20) compared with adjacent normal tissues (n = 20). b Representative tumor adjacent normal tissue, grade I–II, grade II, grade III cervical cancer tissues sections stained with an antibody against COL1A1, respectively. c Optical density measurements indicated that COL1A1 expression from normal cervical specimens to cervical cancer was enhanced gradually. Magnification, ×400. Data are presented as mean ± SEM, *P < 0.05, **P < 0.01
