The gold standard for the detection of urothelial carcinoma is represented by urethro-cystoscopy and biopsy. Both procedures are invasive and expensive and therefore cytology is often used as first approach to investigate on a possible neoplasia, being a safe and cost-effective diagnostic modality of evaluation. Because cytology alone is not highly sensitive for detection of low grade urothelial carcinoma and recurrence of the disease, several adjunct markers and urine based tests for urothelial carcinoma have been developed, which can help in the final diagnosis...

Cervical cancer is the second most common female cancer worldwide. DNA methylation is one of a number of epigenetic regulation mechanisms leading to gene silencing in neoplastic cells. Aberrant methylation results in the silencing of tumor suppressor gene expression, and has been detected in a high percentage of human cancers. In the present study, the methylation status of three tumor suppressor genes, retinoic acid receptor β (RARβ), p16 and cadherin 1 (CDH1), and the inflammatory-associated cyclooxygenase-2 (COX-2) gene, was examined at distinct stages of cervical intraepithelial neoplasia (CIN)...

PROBLEM: APOBEC3G (A3G) is a cytidine deaminase that exhibits antiviral activity by introducing C-to-T hypermutation in viral DNA. We recently observed the distinct presence of C-to-T hypermutation of human papillomavirus DNA in uterine cervical intraepithelial neoplasia (CIN), suggesting the possible involvement of A3G in the mutation-inducing process. Consequently, we investigated the association of A3G expression with CIN progression in this study. METHOD OF STUDY: Patients who had undergone cervical conization due to CIN1 (n=11), CIN2 (n=9), CIN3 (n=12), and micro-invasive squamous cell carcinoma (n=2) were included...
