RNA Sequencing of HEK293T cells expressing a Dual-specificity Aptamer that specifically increases O-GlcNAcylation on beta-catenin when O-GlcNAc transferase was inhibited


ABSTRACT: O-GlcNAc is a dynamic post-translational modification on thousands of intracellular proteins, it regulates protein functions and is involved in many metabolic diseases. Using a dual-specificity aptamer, we targeted the O-GlcNAc transferase (OGT) to endogenous β-catenin and specifically increased O-GlcNAcylation of β-catenin. To study how O-GlcNAcylation of β-catenin regulates the transcriptome, we performed RNA sequencing on HEK293T cells expressing individual (Ctrl.) or dual-specificity aptamers. We found that O-GlcNAcylation of β-catenin shifts the transcriptome in a Wnt-dependent manner: it repressed the expression of about 100 genes in the absence of Wnt, while it activated the expression of these genes when Wnt signaling was turned on. This dataset is from the control experiment in which all samples were treated with the OGT inhibitor Ac5S.
