Regulation of histone H2A.Z expression is mediated by sirtuin 1 in prostate cancer

Histone variants seem to play a major role in gene expression regulation. In prostate cancer, H2A.Z and its acetylated form are implicated in oncogenes’ upregulation. SIRT1, which may act either as tumor suppressor or oncogene, reduces H2A.Z levels in cardiomyocytes, via proteasome-mediated degradation, and this mechanism might be impaired in prostate cancer cells due to sirtuin 1 downregulation. Thus, we aimed...

Monocarboxylate transporter 2 (MCT2) as putative biomarker in prostate cancer

INTRODUCTION: Monocarboxylate transporter 2 (MCT2) is a transmembrane protein involved in the transport of monocarboxylates such as pyruvate and lactate. In a previous study we described overexpression of MCT2 in prostate carcinoma raising the hypothesis of using MCT2 as a possible biomarker in prostate cancer. With the present study we aimed to compare the pattern of expression of MCT2 and alpha-methylacyl-CoA...

Evaluation of immunoexpression and MDR1 promoter methylation levels in prostati...

Os objectivos deste estudo foram: (1) Determinar os níveis de metilação do promotor do MDR1 em tecido prostático com adenocarcinoma (CaP), neoplasia intraepitelial prostática de alto grau (HGPIN), hiperplasia benigna (BPH) e tecido morfologicamente normal (MNP). (2) Correlacionar os níveis de metilação com a imunoexpressão da gp-P. Os nossos resultados demonstram que a hipermetilação do MDR1 constitui um mecani...

P-cadherin overexpression Is an indicator of clinical outcome in invasive breas...

Purpose: P-cadherin overexpressionhas been reported in breast carcinomas,where itwas associated with proliferative high-grade histological tumors. This study aimed to analyze P-cadherin expression in invasive breast cancer and to correlate it with tumor markers, pathologic features, and patient survival. Another purpose was to evaluate the P-cadherin promoter methylation pattern as the molecularmechanismunderly...
