Moreover, metastatic foci appeared in the lungs of the saline, SN38-Lipo@FSH, IR820-Lipo@FSH, and SN38/IR820-Lipo groups, but no tumor metastases were detected in mice treated with SN38/IR820-Lipo@FSH, suggesting that SN38/IR820-Lipo@FSH inhibited tumor metastasis. Here, BRD2 is linked to neoplasm.
