PHA848125 were purchased from Selleckchem. Staurosporine was purchased from
Abcam. Dinaciclib was from Axon Medchem. NVP2 and SB1317 were obtained from
MedChem Express. ATP levels in cells were assessed using the
CellTiter-Glo® Luminescent Cell Viability Assay (Promega). Colony-forming
assays were performed using the CytoSelect 384-well Cell Transformation Assay
(BioCat) according to manufacturer’s instructions. Growth rate and cell
death activation were evaluated using the Incucyte instrument according to
manufacturer’s instructions. For detection of cell death activation, we
used IncuCyte® Caspase-3/7 Green Reagent for Apoptosis (Essen
Biosciences). Cell death activation for

according to the manufacturer’s instructions (the signal from caspase
activity was normalized to signal from viable cells). Cycloheximide (CHX) was
used as a positive control to induce cell death0. Knockdown experiments were
performed using RNAiMax reagent (Sigma). OGT targeting siRNAs were from
ThermoFisher Scientific: siOGT_1 s16094 and siOGT_2 s16095 and CDK9 targeting
siRNA was from Qiagen (SI00024423).
