To confirm that these LSD1i‐mediated effects on cell death and cell cycle contribute to reduced tumor growth in vivo, we performed Ki‐67, TUNEL, and cleaved caspase‐3 immunofluorescence (IF) stainings on tumors harvested after 1 day (D1), 10 days (D10), and at the experimental endpoint. The gene discussed is MKI67; the disease is neoplasm.
