The present study aimed to compare levels of VEGFR2 and MMP-9 among control, epithelial dysplasia (ED) and oral squamous cell carcinoma (OSCC) groups. We analyzed 48 patients with oral leukoplakia (OL), 20 patients with OSCC and 21 patients without OL and OSCC. Immunohistochemistry of VEGFR2 and MMP9 were performed and compared among groups.

Genetic polymorphisms in the promoter region of the tumour necrosis factor-α (TNF-α) gene are involved in the regulation of the expression levels of its cytokine. Besides, these polymorphisms have been associated with the clinical behaviour of cancer. We investigated the -308 promoter region polymorphisms of the TNF-α gene and its association with the(More)
AIM To investigate the association between depression, the normative conditions of oral health and serotonin-transporter-linked promoter region (5-HTTLPR) polymorphisms in a community-dwelling elderly sample. METHODS Elderly adults living in a community (n=200) were submitted to an oral clinical examination. Depression was assessed using the 15-item(More)
De novo DNA methylation is a relevant epigenetic mechanism, which represses gene transcription and commonly inactivates tumor suppressor genes in carcinogenesis. A single nucleotide polymorphism of DNMT3B, C46359T (-149C-->T) was reported to modulate individual's susceptibility to cancer. We investigated the role of this polymorphic variant regarding the(More)
