The Bcl-2 expression profile in normal, low-grade and high-grade squamous intraepithelial lesions and cervical carcinoma tissue of the cervix. a Representative Western blot, *p < 0.05, **p < 0.01, ***p < 0.001. Statistical analysis: ANOVA and Bonferroni correction. All results expressed as mean ± SEM, normal (n = 4), LSIL (n = 6), HSIL (n = 8) and cervical carcinoma (n = 5). b Representative fluorescent micrographs of Bcl-2 expression profiles in normal, LSIL, HSIL and cervical carcinoma, scale bar 20 μm. LSIL low-grade cervical intraepithelial lesions, HSIL high-grade squamous intraepithelial lesions, CA carcinoma
