BCL2 and neoplasm: In terms of nanoscale research, Transferrin-functionalized microemulsions containing CSO and tripterine coloaded with transferrin (Tf-CT-MEs) slowed tumors in vivo in a mouse model of HeLa graft tumors, and Tf-CT-MEs inhibited tumor cell proliferation, enhanced angiogenesis and induced apoptosis by regulating Bax/bcl-2 and caspase-3.
