UBE4B promotes gastric cancer proliferation and metastasis by mediating FAT4 ubiquitination and degradation.

ABSTRACT: The ubiquitin‒proteasome system (UPS), an intracellular protein degradation pathway, plays an important role in regulating tumorigenesis and development. Ubiquitination factor E4B (UBE4B/UFD2) has been shown to be associated with the development of several cancers. The aim of this study was to reveal the functional significance of UBE4B in gastric cancer (GC) development and its important mechanism. Bioinformatics analysis, immunohistochemistry (IHC), western blotting, and real-time PCR were performed to detect UBE4B expression in human GC samples and GC cell lines and a mouse xenograft tumour model was established. Our investigation revealed that UBE4B is highly expressed in GC and promotes the proliferation, migration and invasion of GC cells. The quantitative Tandem Mass Tag (TMT) analy
