Abstract
Fucosylated glycans synthesized by α1,3/4-fucosyltransferase (FUT3) enzyme play an important role in breast cancer prognosis and metastasis, being involved in the binding of circulating tumor cells to the endothelium and being related to tumor stage, metastatic potential and chemoresistance. Despite the pro-tumor action of this enzyme, studies have demonstrated its role in natural killer-induced cytotoxicity through the recognition of sialyl Lewis X by C-type lectin receptors and through extrinsic apoptosis pathway triggered by Apo2L-TRAIL. This study aimed to investigate the expression pattern of FUT3 in invasive breast carcinoma (IDC) from patients of Pernambuco state, Northeast of Brazil, and genotype FUT3 promoter region to identify possible SNPs that could be associated with variations in FUT3 expression. Immunohistochemistry assay was used to access the FUT3 expression in normal (n=11) and tumor tissues (n=85). DNA sequencing was performed to genotype the FUT3 promoter region in patients with IDC (n=109) and healthy controls (n=110). Our results demonstrated that the absence of FUT3 enzyme is related to breast's IDC. The non-expression of FUT3 was more frequent in larger lesions and also in HER2 negative IDC tumors. Genomic analysis showed that two variations localized in FUT3 promoter region are possibly associated with IDC. Our results suggest that minor allele T of SNP rs73920070 (-6933 C>T) confers protection whereas minor allele T of SNP rs2306969 (-6951 C>T) triggers to susceptibility to IDC in the population of Pernambuco state, Northeast of Brazil.

Abstract
Prostatic Adenocarcinoma (PA) and Benign Prostatic Hyperplasia (BPH) have their etiology not fully understood mainly in glycidic aspects. Glycan changes are associated with cell alterations where glycosylation is carried out by glycosyltransferases, such as fucosyltransferases (FUTs). These enzymes catalyze the insertion of L-fucose residues in a variety of glycan structures often in the final stage of glycosylation. The present study aimed to investigate the expression of FUT3 and FUT6 in PA and BPH as well as to correlate immunostaining of these transferases with PA clinic-histopathologic data. The FUT3 and FUT6 expressions were evaluated by immunohistochemistry in formalin-fixed, paraffin-embedded biopsies of PA (n=40) and BPH (n=40). FUT3 and FUT6 showed a high expression in both prostatic diseases, especially FUT6. FUT6 was more immunoexpressed in PA cases than the FUT3 (p<0.0001) as well as in BPH cases but in a not significant way (p=0.0661). Besides, FUT3 was more expressed in BHP lesion than in PA cases (p<0.0001). Our study presented a new data about FUT3 and FUT6 expression in PA and BPH, revealing high FUT6 expression in both lesions and FUT3 overexpression in BHP in relation to PA, proposing that this enzyme could be a promising biomarker for benign prostate alterations.
