Figure 2a presents representative images of mice injected with cells derived from PBS, nanodiamond, epirubicin, or EPND-treated MYC-driven tumors. The results highlight that mice receiving EPND-treated tumor cells showed no detectable tumor formation, in stark contrast to significant tumor growth in other groups. Figure 2b provides a quantitative analysis of tumor formation rates, demonstrating a substantial reduction in allograft tumor initiation with EPND treatment. The gene discussed is MYC; the disease is neoplasm.
