| Abstract: | Infection by high-risk human papillomaviruses (HPVs) is considered to be the central cause of invasive cervical cancer. Previously reported studies have shown that Id genes regulate cell invasion and metastasis in several human carcinomas including cervical cancer. In order to investigate the correlation between high-risk HPVs and Id genes in human cervical cancer, the presence of high-risk HPVs and their association with Id gene expression was examined using PCR methods and tissue microarray analyses in a cohort of 44 cervical cancer patients from Syria. This study showed that high-risk HPVs were present in 42 samples (95%) that represent invasive cervical cancers and that the most frequent high-risk HPV types in Syrian women were 33, 16, 18, 45, 52, 58, 35, 51 and 31. Furthermore, the expression of E6 oncoprotein of high-risk HPVs was found to correlate with overexpression of Id-1, but not of Id-2, Id-3 or Id-4 in the majority of invasive cervical cancer tissue samples. These data suggest that high-risk HPVs can enhance the progression of human cervical cancer through Id-1 regulation. |
