Cytology samples were examined for aberrant DNA methylation of DLX4 and SIM1 genes and protein expressions. CaSki cells were treated with 5\u2010Aza\u20102\u2032\u2010deoxycytidine (5\u2010aza\u2010dC).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Group 1 was negative for intraepithelial lesions or malignancies. LSIL in group 2 showed a continuance of LSIL for longer than 365 days and LSIL in group 3 showed an upgrading to high\u2010grade (H) SIL or higher (HSIL+) within 365 days of LSIL diagnosis. Group 4 was squamous cell carcinoma. All but group 1 were infected with hrHPV. Significant differences existed in the frequency of DNA methylation between groups 2 and 3 (p\u2009=\u20090.044), between groups 3 and 4 (p\u2009=\u20090.020) for DLX4, and between groups 1 and 3 (p\u2009=\u20090.0003), and groups 2 and 3 (p\u2009=\u20090.005) for the SIM1 gene. DLX4 protein expression was significantly reduced in the DLX4 methylation positive tissues (p\u2009=\u20090.008). The 5\u2010aza\u2010dC treatment restored DLX4 mRNA expressions of CaSki cells (p\u2009&lt;\u20090.005). The LSIL cases with DNA methylation of the SIM1 gene, or both genes, progressed faster to HSIL+ than did the others (p\u2009=\u20090.033 and p\u2009=\u20090.045, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Aberrant DNA methylation of the DLX4 and SIM1 genes should be a novel progression marker for uterine cervical LSIL with hrHPV infection.
