description: Additional file 4: Supplementary Fig. 4. A) Kaplan–Meier survival curve of mice from the experiment performed in Fig. 6A. The Kaplan–Meier survival plot was created using a tumor volume threshold of 1,000 mm3. P values were calculated using one-sided log-rank tests. B) Effect of the anti-CD98hc ADC on the weight of mice xenografted with HT29 cells. Data are plotted as mean ± SD of six mice/group. C) Analysis of the antitumoral effect of naked anti-CD98hc and DM1 on tumor growth in nude mice implanted with HT29 cells. Arrows indicate days of administration of anti-CD98hc (15 mg/Kg) or DM1 (0.14 mg/Kg). Data are plotted as mean tumor volumes ± SEM. P values were calculated using Student’s t test (two-sided). D) Kaplan–Meier survival curve of mice from the experiment of panel C. The Kaplan–Meier survival plot was created using a tumor volume threshold of 650 mm3. P values were calculated using one-sided log-rank tests. E) Expression levels or phosphorylation of proteins involved in cell cycle and apoptosis in the tumors of the experiment performed in Fig. 6A. Tumor samples were obtained on day 21 after initiation of treatments (seven days after the last treatment). Tissue extracts of the tumors were used to analyze the levels of expression of pH3, PARP, pH2AX, pCDK1 and cleaved Caspase 3. Stain free blot was analyzed to verify equal loading. F) Quantitation of the levels of DM1 (data shown in Fig. 6B), pH3, PARP, pH2AX, pCDK1 and cleaved Caspase 3 of the experiments shown in panel E. The graphs represent the mean intensity (arbitrary units) ± SD of the different proteins present in control (C) or treated (anti-CD98hc-DM1) mice groups. P values were calculated using Student’s t test (two-sided). G) Immunohistochemical detection of CD98hc in PDX BT6224 (P2M1: passage 2, mouse #1) using the anti-CD98hcV509 antibody. H) Kaplan–Meier survival curve of mice from the experiment performed in Fig. 6E. The Kaplan–Meier survival plot was created using a tumor volume threshold of 800 mm3. P values were calculated using one-sided log-rank tests. I) Effect of the anti-CD98hc ADC on the weight of mice xenografted with PDX BT6224. Data are plotted as mean ± SD of four mice/group. J) Quantitation of the levels of DM1 of the experiments performed in Fig. 6F. The graphs represent the mean intensity (arbitrary units) ± SD of IgG Heavy and Light chains coupled to DM1 present in control (C) or treated (anti-CD98hc-DM1) groups. P values were calculated using Student’s t test (two-sided).
