FOXM1 and neoplasm: To elucidate whether tumor‐conditioned medium suppressed BMDC maturation via elevated H3K79me2‐FOXM1 expression, we conducted an in vivo experiment pretreating BMDCs from wild‐type mice with conditioned medium from Panc02 or CT‐26 cells, mimicking TME, before pulsing them with EPZ or Thiostrepton.
