(D) Western blot analysis of protein lysates from two independent cultures of wild-type and Hint null MEFs with a Cdk2 antibody recognizing total Cdk2 levels. In vitro Cdk2 kinase activity from unsynchronized Hint wild-type and Hint null MEFs was assayed by using histone H1 (H1) as a substrate following anti-Cdk2 immunoprecipitation. (E) [3H]thymidine incorporation of wild-type and Hint null MEFs labeled at different times after release to G1 by readdition of serum to starved cells. Standard deviations (error bars) originate from duplicates of three independent primary cultures for each genotype.

Fig. 1 Efficacy of XL102 and its effects on downstream targets of <t>CDK7.</t> A Kinase activity of <t>CDK7</t> in the presence of XL102 was measured using the LANCE TR-FRET in vitro kinase assay by incubating both CDK7 and XL102 followed by addition of ATP and U-light-MBP peptide substrate. Time-resolved fluorescence (excitation, 320 nm; emission donor, 615 nm; emission acceptor, 665 nm) was monitored by using 2030 multilabel reader Victor5 (PerkinElmer). The IC50 values were derived by fitting a sigmoidal dose–response curve to a plot of assay readout over inhibitor concentration, computed with the Graph Pad Prism. B The pull-down assay using bio-THZ1 show a dose dependent target engagement in AML cells harvested after 3 h of XL102 treatment followed by washing to remove any unbound XL102 (time point-0 h). C XL102 inhibited CTD phosphorylation of conserved residues of RPII in AML cells in dose dependent manner at 6 h and 24 h along with quantification of Western blot data. Results are the mean ± SD of three independent experiments

Fig. 1 Efficacy of XL102 and its effects on downstream targets of CDK7. A Kinase activity of CDK7 in the presence of XL102 was measured using the LANCE TR-FRET in vitro kinase assay by incubating both CDK7 and XL102 followed by addition of ATP and U-light-MBP peptide substrate. Time-resolved fluorescence (excitation, 320 nm; emission donor, 615 nm; emission acceptor, 665 nm) was monitored by using 2030 multilabel reader Victor5 (PerkinElmer). The IC50 values were derived by fitting a sigmoidal dose–response curve to a plot of assay readout over inhibitor concentration, computed with the Graph Pad Prism. B The pull-down assay using bio-THZ1 show a dose dependent target engagement in AML cells harvested after 3 h of XL102 treatment followed by washing to remove any unbound XL102 (time point-0 h). C XL102 inhibited CTD phosphorylation of conserved residues of RPII in AML cells in dose dependent manner at 6 h and 24 h along with quantification of Western blot data. Results are the mean ± SD of three independent experiments
