PAX1 and cervical squamous cell carcinoma: Moreover, the quantitative level of PAX1 gene methylation in 121 cervical tissues showed that the quantitative level of PAX1 gene methylation was (4.92 ± 4.45)% in normal cervical tissues, (5.55 ± 5.05)% in the low‐grade lesion group, (10.21 ± 14.39)% in the high‐grade lesion group, and (41.97 ± 23.02)% in the cervical squamous cell carcinoma group [19].
