| Outline of Final Research Achievements |
In this study, we report the critical role of an unknown glycosyltransferase GTUF (GlycosylTransferase of Unknown Function) in breast cancer cells. Although GTUF was frequently up-regulated in breast cancer cells, including triple negative breast cancer (TNBC) cells, it was not significantly expressed in normal tissues. Knockdown of GTUF by siRNA significantly suppressed cell growth and induced apoptosis in both TNBC and non-TNBC cells. GTUF has two glycosylated sites and its glycosylation is important for secretion into culture medium from cells. These results suggested that GTUF might be a novel therapeutic target and molecular marker of breast cancer.
