The study investigates the effects of R3Mab on serum levels of human pro-MMP-10 in mice with RT112 and UMUC-14 xenograft tumors. Mice with established tumors received either a control antibody or R3Mab treatment. Serum was collected at 48 and 96 hours post-treatment, and human pro-MMP-10 levels were measured using ELISA. The results indicate that R3Mab significantly reduces pro-MMP-10 levels in a dose- and time-dependent manner, providing insights into its potential therapeutic benefits in cancer models.

Pro-MMP-10 (ng/mL) 48 hr 96 hr Supplemental Figure 6 R3Mab reduces serum levels of human pro-MMP-10 in mice bearing RT112 xenograft tumors in a dose- and time-dependent manner. Mice with pre-established RT112 tumors were grouped randomly into cohorts of 5 for treatment with either a control antibody (0) or R3Mab (3 or 30 mg/kg). Serum was collected at 48 hr or 96 hr post-treatment, and human pro-MMP-10 level was measured by Elisa.
A B Supplemental Figure 7 R3Mab reduces serum levels of human MMP-1 and pro-MMP-10 in mice bearing UMUC-14 xenograft tumors. Mice with pre-established UMUC-14 tumors were grouped randomly into cohorts of 10 and treated with a control antibody (Ctrl Ab) or R3Mab (30 mg/kg). Serum was collected at indicated time points, and subject to ELISA for total human MMP-1 (A) and pro-MMP-10 (B).
