82% vs. 18% (p<0.01) and 84% vs. 39% (p<0.01), respectively, while SOX17 methylation frequency was significantly higher in SCC than AdCA, i.e.89% vs. 62% (p<0.05).
RASSF1A methylation was found in 27 adenocarcinomas (23.5%) and inversely correlated with KRAS and/or BRAF mutation (p=0.002) in cervical adenocarcinoma.
FABP4 was specifically elevated in tissue samples from patients with cervical squamous cell carcinoma (CSCC) but not with cervical adenocarcinoma, and the level of FABP4 was correlated with E-cadherin and Vimentin expression.
According to qRT-PCR, methylation level of SOX1 in cervical adenocarcinoma tissues is significantly different from that in cervical squamous cell carcinoma tissues or normal cervical tissues, and the methylation level of CCND1 in cervical adenocarcinoma tissues or cervical squamous cell carcinoma tissues is significantly different from that in normal cervical tissues.The present study demonstrates that tumor-suppressor gene SOX1 is a methylation-specific expression gene of cervical adenocarcinoma and is expected to become a specific molecular marker for the diagnosis of cervical adenocarcinoma.
After Bonferroni correction adjustment (statistically significant at p < 0.0055), we found that the aberrant hypermethylations of CDH1 and DAPK were more frequent in CSCCs than in CAs (80.6% vs. 43.3%, p = 0.001; 77.4% vs. 46.7%, p = 0.005), whereas HLTF and TIMP3 were more frequently methylated in CAs (3.2% vs. 43.3%, p < 0.001; 8.1% vs. 53.3%, p = 0.001).

Analysis and clinical implications of K-ras gene mutations and infection with human papillomavirus types 16 and 18 in primary adenocarcinoma of the uterine cervix.
Apoptosis appears to occur in the cancerous cells of invasive adenocarcinoma of the uterine cervix in association with a high level of expression of Bax but not of bcl-2.
As p53 mutations are more frequently detected in malignancies of high grade, high stage, and large size, this molecular event seems to play a role in the progression rather than in the induction of cervical adenocarcinoma.
Cultured human glioma (NG97), glioblastoma (U-251) and cervix adenocarcinoma (HeLa) cells, and nontumor mouse fibroblasts (L929) were treated with low (14 µg/ml) and high (280 µg/ml) concentrations of PnV, and analyzed through assays for cell viability (thiazolyl blue tetrazolium blue), proliferation (carboxyfluorescein succinimidyl ester), death (annexin V/propidium iodide [Pi]), the cell cycle (Pi), and migration (wound healing and transwell assay).
Cytoplasmic HDGF expression is strongly correlated with pelvic lymph node metastasis and recurrence, indicating that HDGF may serve as a novel prognostic marker for patients with Cx.
