Carcinoma ex pleomorphic adenoma is a rare salivary gland malignancy. It constitutes an important model for the study of carcinogenesis, as it can display the tumor in different stages of… Expand
Yeast oxidative stress response
We investigated the changes in the oxidative stress response of yeast cells suffering mitochondrial dysfunction that could impair their viability. First, we demonstrated that cells with this… Expand

Aims To broaden understanding of phenomena involved in progression from classical adenoid cystic carcinomas (ACCs) to tumours with high-grade transformation (ACC-HGT) Methods Expression of proteins… Expand
Cytosolic thioredoxin peroxidase I is essential for the antioxidant defense of yeast with dysfunctional mitochondria
The specific role of cytosolic thioredoxin peroxidase I (cTPx I), encoded by TSA1 (thiol‐specific antioxidant), was investigated in the oxidative stress response of Saccharomyces cerevisiae. In most… Expand
Angiogenesis in salivary carcinomas with and without myoepithelial differentiation
To investigate whether salivary carcinomas with and without myoepithelial differentiation could present differences regarding degree of angiogenesis, we compared tumor vascularization between adenoid… Expand

Cysteine plays structural roles in proteins and can also participate in electron transfer reactions, when some structural folds provide appropriated environments for stabilization of its sulfhydryl… Expand
Involvement of the Wnt-β-catenin signalling antagonists, sclerostin and dickkopf-related protein 1, in chronic periodontitis.
AIM The regulation of Wnt-β-catenin signalling, which is crucial for osteoblast differentiation and for bone resorption, is driven by critical inhibitors such as sclerostin (SOST) and… Expand
Increased mucin 1 expression in recurrence and malignant transformation of salivary gland pleomorphic adenoma
Soares A B, Demasi A P D, Altemani A & de Araújo V C (2011) Histopathology58, 377–382 Increased mucin 1 expression in recurrence and malignant transformation of salivary gland pleomorphic adenoma
The expression of antioxidant enzymes in the gingivae of type 2 diabetics with chronic periodontitis.
OBJECTIVES There is controversial evidence regarding the levels of antioxidant molecules in type 2 diabetes periodontitis patients. Thus, the aim of the present study was to evaluate the gene… Expand
