To examine this potential, the effect of EOAI3402143 (G9) treatment is investigated on human MIAPACA2 tumor xenografts. Human MIAPACA2 cells are injected subcutaneously into NSG mice. Primary tumor development is monitored by caliper measurements, and once measurable, mice are separated into two groups and are treated with either vehicle control (PEG300/DMSO) or G9 at 15 mg/kg. Tumor growth, animal weight, behavior, and mobility are monitored during treatment. In parallel, murine 8041 tumors are also established and subjected to similar G9 treatment and tumor monitoring regimen as the human MIAPACA2 xenografts. Consistent with the in vitro findings, Usp9x inhibition results in the suppression of tumor growth in human tumor xenografts, but any significant effect on the growth of 8041 tumors xenografts is not observed, although the Usp9x activity is inhibited effectively by EOAI3402143 treatment in both human MIAPACA2 and mouse 8041 xenograft tumors^[3].
