PXD selectively inhibits CSF-1R, c-KIT proto-oncogene receptor tyrosine kinase (KIT), and Fms-like tyrosine kinase 3 internal tandem duplication mutation sinFms-like tyrosine kinase-3 (FLT3-ITD), thus acting as an inhibitor of tumor cell proliferation [5]. This evidence concerns the gene FLT3 and neoplasm.
