1. Cellular Thermal Shift Assay (CETSA): MDA-MB-231 cells were treated for 6h with DMSO or SU212 and incubated at different temperatures and protein differences in the soluble fractions were determined. 2. Quantitative Proteomics: MDA-MB-231, MDA-MB-468, and BT549 cells were treated with DMSO (vehicle control) or SU212 (novel small molecule drug candidate). Quantitative proteomics analysis was performed on cell lysates.
