Grape proanthocyanidins (PA) play a major role in organoleptic properties of wine, being involved in astringency and color stability. They are accumulated mainly in skin and seeds during early stages of berry development. Numerous structural genes involved in PA biosynthesis have already been identified even in grape, but some steps are still not documented.A previous transcriptomic study led to identify new genes putatively involved in the PA pathway (Terrier et al., 2009). Among them, 3 glucosyltransferases and 2 glucose acyl transferases were identified. The objective of this work is to clarify the function of these genes in the phenylpropanoid pathway.The three glucosyltransferases called VvgGT1, VvgGT2, VvgGT3 displayed high sequence similarities between them and with other plant glucosyltransferases able to catalyze the formation of glucose esters. The transcripts are expressed in the early stages of grape berry development, mainly in skins and seeds and also in the pulp for VvgGT2. The properties of these 3 enzymes (Km, Vm, substrate specificity, pH sensitivity) were studied in vitro after production of recombinant proteins. The three of them are able to catalyse the synthesis of glucose ester with derivates of hydroxybenzoic acids and hydroxycinnamic acids as substrates and with similar kinetic properties.Two glucose-acyltransferases called VvGAT1 and VvGAT2 were isolated. They displayed high sequence similarity with other Serine carboxypeptidase like acyltransferases-glucose dependent. The transcripts are expressed in early stages of grape berry development mainly in skins and seeds for VvGAT1 and in pulp and seeds for VvGAT2. Heterologous expression of the proteins in different hosts were unsuccessful. The confocal microscopy data suggest that VvGAT1 fused to GFP are localized in cytosolic vesicles.The successive involvement of those VvgGT and VvGAT in the galloylation of PAs and in the synthesis of hydroxycinnamic esters is discussed

Human 17β-hydroxysteroid dehydrogenase type 7 (17β-HSD7) displays a dual function in cholesterogenesis and steroidogenesis. In steroidogenesis, it is both involved in the formation of the estradiol (E2) from estrone (E1) and in the degradation of dihydroterstosterone (DHT) into weak estrogen 5α-androstane-3β, 17β-diol (3β-diol). However, its function in estrogen dependent breast cancer (estrogen receptor positive, ER+) has been unclear for many years. E2 stimulates breast cancer cells (BCCs, MCF-7 cells) growth via estrogen receptor (ER) whereas DHT displays anti-proliferative effects via androgen receptor (AR). In the present thesis, the function of 17β-HSD7 in ER+ breast cancer was studied with in vitro, in vivo, proteomics and three dimensional (3D) co-culture model and results were described: (1) Inhibition of 17β-HSD7 by its selective inhibitor (INH7) in BCCs induced significant lower E2, higher DHT, cell cycle arresting and negative regulating of the same enzyme. Such inhibition induced significant shrinkage of xenograft tumors accompanied by decreased E2 and elevated DHT in plasma. (2) Inhibition of 17β-HSD7modulated 104 proteins involved in different biological processes. INH7 especially suppresses the expression of glucose regulated protein 78 (GRP78) and consequently enhanced apoptosis of MCF-7 towards aromatase inhibitor. (3) The interactions between BCCs and tumor fibroblast modulate steroidogenic enzymes. 17β-HSD7 was the most modulated enzyme in MCF-7 cells whereas aromatase was the most regulated enzyme in fibroblast (Hs578Bst). Such regulations led to an increasing of E2 conversion from precursors and promoted MCF-7 cells’ proliferation. The increased cell proliferation was blocked by aromatase inhibitor in 3D co-culture system, but more significant results were observed with INH7 which blocked DHT degradation. (4) Integrative data analysis with The Cancer Genome Atlas (TCGA) confirmed the significant amplification of 17β-HSD7 in various breast cancers compared to normal breast tissue. Thus, in the present thesis, 17β-HSD7 was characterized as a novel therapeutic target for estrogen dependent breast cancer in postmenopausal women.
