Myc de-activation triggered an immediate drop in tumor cell proliferation, rapid exit of macrophages and re-entry of CD3+ T cells, an influx of NKp46+ NK cells, and induction of tumor apoptosis (Figure 5A) and tumor regression, evident by the appearance of voids within the tumor masses and profound drop in overall tumor burden (Figure 5B). This evidence concerns the gene NCR1 and neoplasm.
