Expression of epidermal growth factor receptor and human papillomavirus E6/E7 proteins in cervical carcinoma cells.
BACKGROUND Epidermal growth factor receptor (EGF-R) proteins are highly expressed in many tumors, including those of the cervix. We have observed previously that the introduction of a transcription unit containing an antisense sequence for the E6/E7 genes of human papillomavirus (HPV) 18, along with a transcription unit containing a sense complementary DNA sequence for the wild-type retinoblast...
متن کاملExpression of the Fragile Histidine Triad Gene in Laryngeal Carcinoma
The aim of this study was to investigate Fragile Histidine Triad Gene (FHIT) expression in laryngeal squamous cell carcinoma. The paraffin embedded tissue blocks of 64 laryngeal squamous cell carcinoma specimens were enrolled in the study. FHIT expression was detected by an immunohistochemical method. Rabbit polyclonal antibody was used for immunohistochemical study. FHIT expression was low in ...
متن کاملHuman Papillomavirus DNA and E6/E7 mRNA Status in Relation to Survival of Patients Treated for Cervical Squamous Cell Carcinoma
The prognostic significance of human papillomavirus (HPV) DNA and E6/E7 mRNA, the presence of specific types, and the physical state of HPV DNA, were studied in 202 cervical squamous cell carcinomas. Absence or non-detectable levels of high-risk (types 16, 18, 31, 33, 35, 45, 52 and 58) E6/E7 mRNA, using the real-time nucleic acid sequence based amplification (NASBA) assay, and absence of HPV h...
متن کاملDiagnostic validity of human papillomavirus E6/E7 mRNA test in cervical cytological samples.
Human papillomavirus (HPV) DNA tests tend to show high sensitivity, but poor specificity in detecting high-grade cervical lesions. This study aimed to explore the clinical performance of QuantiVirus(®) HPV E6/E7 mRNA in identifying ≥Grade 2 cervical intraepithelial neoplasia. Thin-prep(®) liquid based cytology test (LBC) samples were collected from October 2009 to October 2011 from women who un...
متن کاملRestored expression of fragile histidine triad protein and tumorigenicity of cervical carcinoma cells.
BACKGROUND Allelic losses in the short arm of chromosome 3 are common in cervical carcinomas. The fragile histidine triad (FHIT) gene at chromosome region 3p14.2 is a candidate tumor suppressor gene that may play a role in cervical tumorigenesis. We and others have identified aberrant FHIT transcripts and frequent loss of Fhit protein expression in primary cervical cancers and high-grade noninv...
