The Anti-cancer Factor Quinolinone Inhibitors Disrupt Spindles and the Interactions between LSF and Microtubule-associated Proteins

Identification of mitotic BioLSF-interacting proteins whose association is sensitive to Factor Quinolinone Inhibitor 1 (FQI1): The dataset is comprised of two independent experimental replicates, with each biological replicate consisting of runs of 4 samples. For each set, the four protein samples were generated from cells in mitosis, in which cells lacked, expressed basal levels, or expressed induced levels of a biotinylated, tagged LSF protein (BioLSF). Finally, cells with induced BioLSF levels were treated for one hour in mitosis with either FQI1 or vehicle (DMSO). Proteins purified on streptavidin beads were analyzed by mass spectrometry. More specifically, the four runs in each set derived from: 1) DLD-1 Flp-In™ T-REx™ TIR1 parental cells treated with vehicle (Parent_DMSO) as a negative control, 2) DLD-1 Flp-In™ T-REx™ TIR1 BioLSF cells with only leaky, basal BioLSF expression (BioLSF_DMSO), 3) DLD-1 Flp-In™ T-REx™ TIR1 BioLSF cells with induced BioLSF expression (BioLSF_DOX), and 4) DLD-1 Flp-In™ T-REx™ TIR1 BioLSF cells with induced BioLSF expression that were treated with FQI1 in mitosis (BioLSF_DOX_FQI1).
