The aim of this study is to determine the prognostic value of tumor markers, as squamous cell carcinoma antigen (SCCAg) and cytokeratin-19 fragment (CYFRA 21.1) and interleukin 6 (IL-6), vascular endothelial growth factor (VEGF), soluble tumor necrosis factor receptor I (sTNF RI), and sTNF RII in patients with squamous cell carcinoma of the cervix.
In this study, we show that IL-6 receptor (IL-6R) and signal transducer and activator of transcription 3 (Stat3) were highly expressed in human cervical squamous cell carcinoma (CSCC) tissues, and the expression of EMT markers was reversed in well-differentiated and poorly-differentiated human CSCC.
The effect of the EGFR tyrosine kinase inhibitor BIBX1382BS on radiation sensitivity was determined after single- and fractionated-dose irradiation in human cell lines of bronchial carcinoma (A549), breast adeno-carcinoma (MDA-MB-231), pharyngeal squamous-cell carcinoma (FaDu), squamous-cell carcinoma of cervix (HTB-35) as well as normal (HSF-7) and transformed (HH4-DED) human skin fibroblasts.
