P16(INK4a) expression as a potential prognostic marker in cervical pre-neoplastic and neoplastic lesions.
An immunohistochemical analysis with monoclonal antibody p16(INK4a) was performed in formalin-fixed, paraffin-embedded samples of 60 cases. The aim was to investigate in biopsies the expression of p16(INK4a) of normal uterine cervical tissue, pre-cancerous and cancerous lesions, and their relation with human papilloma virus (HPV) and HIV status. Three parameters were evaluated: percentage of p1...
متن کاملDNA nanotherapy for pre-neoplastic cervical lesions.
OBJECTIVE This study aims to test the hypothesis that targeted nanoparticle delivery of DNA encoding HPV16-regulated diphtheria toxin (DT-A) will result in the death of HPV16-infected cells. MATERIALS AND METHODS Plasmid constructs containing a HPV16 Long Control Region (LCR) DNA sequence upstream of DT-A or luciferase reporter (Luc) DNA sequences were used to formulate poly(β-amino ester) na...
متن کاملIMMUNOHISTOCHEMICAL EXPRESSION OF P16INK4a IN INFLAMMATORY, PRENEOPLASTIC AND NEOPLASTIC CERVICAL LESIONS.
INTRODUCTION High-risk human papilloma viruses play a main role in the development of cervical dysplasias and carcinomas. p16INK4a can be considered as a surrogate marker of active high-risk human papillomaviruses infection in dysplastic and neoplastic cells of the cervix. This study was aimed at determining the presence and level of pl6INK4a expression in inflammatory, preneoplastic and neopla...
متن کاملPromoter methylation of tumor suppressor genes in pre-neoplastic lesions; potential marker of disease recurrence
BACKGROUND Epigenetic alterations of specific genes have been reported to be related to colorectal cancer (CRC) transformation and would also appear to be involved in the early stages of colorectal carcinogenesis. Little data are available on the role of these alterations in determining a different risk of colorectal lesion recurrence. The aim of the present study was to verify whether epigenet...
متن کاملChlamydia trachomatis and human papillomavirus coinfection: association with p16INK4a and Ki67 expression in biopsies of patients with pre-neoplastic and neoplastic lesions.
The objective of this study was to identify the frequency of coinfection by human papillomavirus (HPV) and Chlamydia trachomatis (CT) in cervical lesions and relate it with immunohistochemical expression of p16INK4a and Ki67, both oncogenicity markers. A cross-sectional study with 86 women from primary care units in southern Brazil was conducted. Cervical swabs were collected for HPV-DNA and CT...
