Objective
This study aimed to evaluate the presence of human papillomavirus (HPV) and Epstein–Barr virus (EBV) and the expression of p53, p16, E‐cadherin, COX‐2, MLH1, and MYC in oral squamous cell carcinoma (OSCC).
Materials and Methods
One hundred OSCC specimens were submitted to in situ hybridization for HPV and EBV, and immunohistochemistry for detection of the human proteins.
Results
Thirty‐one...
Evidence suggests that the carcinogenic process guided by Helicobacter pylori is related to the expression of cell cycle and apoptosis proteins as BCL-2, BAX, and MYC. However, the literature is conflicting regarding the expression frequency in the histological subtypes and did not consider cagA gene presence. To investigate the expression of these proteins considering the histological subtypes of...
