|Title:||Up-regulation Of 14-3-3σ (stratifin) Is Associated With High-grade Cin And High-risk Human Papillomavirus (hpv) At Baseline But Does Not Predict Outcomes Of Hr-hpv Infections Or Incident Cin In The Lams* Study|
|Abstract:||To assess whether the potentially high-risk (HR) human papillomavirus (HPV)-related up-regulation of 14-3-3σ (stratifin) has implications in the outcome of HPV infections or cervical intraepithelial neoplasia (CIN) lesions, cervical biopsy specimens from 225 women in the Latin American Screening Study were analyzed for 14-3-3σ expression using immunohistochemical analysis. We assessed its associations with CIN grade and HR HPV at baseline and value in predicting outcomes of HR-HPV infections and the development of incident CIN 1+ and CIN 2+. Expression of 14-3-3σ increased in parallel with the lesion grade. Up-regulation was also significantly related to HR-HPV detection (P = .004; odds ratio, 2.71; 95% confidence interval, 1.37-5.35) and showed a linear relationship to HR-HPV loads (P = .003). 14-3-3σ expression was of no value in predicting the outcomes (incident, persistent, clearance) of HR-HPV infections or incident CIN 1+ and CIN 2+. 14-3-3σ is not inactivated in cervical carcinoma and CIN but is up-regulated on transition from CIN 2 to CIN 3. Its normal functions in controlling G1/S and G2/M checkpoints are being bypassed by HR HPV. © American Society for Clinical Pathology.|
