a Schematic representation outlining the criteria for selecting the tumor for the PDX model based on Western blot screening of YAP1 Ser397 phosphorylation. The tumor with the highest YAP1 phosphorylation levels was chosen for implantation. Mice were treated with 10 mg/kg/day alisertib five days a week and/or 0.4 mg/mice/day cetuximab twice a week for 21 days. Tumor volume and body weight was measured three times a week. Created with BioRender.com b Tumor volume measurement during 21-day treatment with alisertib and/or cetuximab. Representative images of tumors extrated from each group of mice. Results are plotted as the average ± SD of all the tumor volumes for each condition, ***p < 0.001 (n = 6), two-way ANOVA. c T/C (treated/control) ratio of tumors after the 21-day treatment with alisertib, cetuximab and combination. d Ki67 staining of tumors treated with alisertib, cetuximab, the combination of both or neither. *p < 0.05 (n = 3), Welch and Brown-Forsythe ANOVA. CTR Control, ALS Alisertib, CTX Cetuximab, COM Combined.
