Nanostring data from BRD4 inhibitor–treated tumors also revealed decreased tumor expression of chemokines important for MDSC recruitment to tumors including CXCL5, CXCL3, and CCL2, suggesting that the reduced intratumoral MDSC levels could be caused by impaired MDSC migration into the TME. The gene discussed is CXCL3; the disease is neoplasm.
