Additionally, we found that PDCD11 silencing significantly decreased Ki67 levels (p < 0.001), a canonical marker indicating tumor cell proliferation,[28] in both MDA‐MB‐231 and HT‐29 tumors, further confirming the antitumor efficacy of shPDCD11 (Figure 6D,E). The gene discussed is MKI67; the disease is neoplasm.
