| ABSTRACT Inulin is an effective prebiotic and its potential in modulating systemic immunity have been proposed. A subpopulation of T cells, named T regulatory cells (Tregs), expressing the Forkhead boxP3 transcription factor are key mediators of peripheral tolerance and suppress undesirable immune responses. These Tregs can be induced by cytokine transforming growth factor beta (TGF-β) and interleukin 10 (IL-10). This work aimed to evaluate inulin effects on human peripheral blood mononuclear cells (PBMC) in vitro. PBMC were incubated with inulin, and the expression of TGF-(1, FOXP3 and IL-10 was analyzed. Increased supernatant IL-10 levels were observed in PBMC of inulin-treated group (p=0.03). Moreover, FOXP3 gene expression was 7.6 fold higher in... |

| A subgroup of tumor that has received attention is triple-negative breast cancer (TNBC), which presents phenotype of negative estrogen receptor, negative progesterone receptor and has no overexpression of HER2. TP53 acts as a tumor suppressor limiting the proliferation of damaged cells. A polymorphic site (rs1042522) of TP53 encodes either an arginine or a proline amino acid, but its biological significance remains unclear. This study aimed to investigate this variant and its expression in search for a possible involvement in TNBC susceptibility and clinical outcome. Genetic polymorphism was evaluated in 50 patients and 115 controls by PCR based methodology and immunohistochemistry was done with monoclonal antibody. Case-control study showed no positive or... |
