p16INK4A overexpression in precancerous and cancerous lesions of the uterine cervix in Tunisian women.

Uterine cervix cancer is an important public health problem in developing countries. However, there is a substantial lack of inter-observer diagnostic reproducibility for its precursor lesions (CIN1). The study was performed to evaluate the usefulness of p16(INK4A) overexpression as a surrogate marker for uterine cervix precancerous lesions and high-risk human papillomavirus (HPV) infection.

DNA methyltransferase DNMT3b protein overexpression as a prognostic factor in patients with diffuse large B-cell lymphomas.

Diffuse large B-cell lymphomas (DLBCL) are the most common type of aggressive lymphomas, with considerable heterogeneity in clinical presentation, molecular characteristics, and outcome. Previous studies have showed significant correlations between DNA methyltransferase (DNMT) overexpression and unfavorable prognosis in human cancers. Therefore, we investigated in this study the biological and prognostic significance of DNMT1, DNMT3a, and DNMT3b protein expression in DLBCL.
