Mechanism of hpv and cervical cancer

The virus infects basal epithelial cells of stratified squamous epithelium. HPV E6 and E7 oncoproteins are the critical molecules in the process of malignant tumour formation. Interacting with various cellular proteins, E6 and E7 influence fundamental cellular functions like cell cycle regulation, telomere maintenance, susceptibility to apoptosis, intercellular adhesion and regulation of immune responses.

The biologic behavior of squamous cervical carcinoma after neoadjuvant therapy NAT according to immunohistochemical expression of E-cadherin and CD44v6 Mihaela Madalina Gavrilescu, Raluca Balan, Viorel Scripcariu, Dan Ferariu, Ludmila Lozneanu, Diana Popovici, Cornelia Amalinei Abstract The efficiency of neoadjuvant therapy in cervical carcinoma has been well demonstrated, although the cellular mechanisms of different response to this treatment mechanism of hpv and cervical cancer not been thoroughly investigated.

The aim of our study was to assess the correlations between the alterations in E-cadherin and CD44v6 immunoexpression in cervical carcinoma, as a tool of evaluation the response to neoadjuvant therapy and its prognostic significance.

The intensity of CD44v6 immunoexpression was higher in more aggressive tumors and E-cadherin immunoexpression was approximately constant among the cases with neoadjuvant therapy. Our results demonstrate that the evaluation of CD44v6 immunoexpression in cervical carcinomas is useful mechanism of hpv and cervical cancer the assessment of tumor response to neoadjuvant therapy and of tumor aggressiveness.

The high level of E-cadherin mechanism of hpv and cervical cancer in tumors with neoadjuvant therapy reflects its involvement in mechanism of hpv and cervical cancer prevention of HPV oncoproteins action, with benefits on the outcome. A larger group of patients and a panel of antibodies, including CD4 and COX2, could provide a better characterization of the tumor response to neoadjuvant therapy, with a positive prognosis impact.
