Furthermore, the neutralizing effect of the anti-FABP4 mAb on rhFABP4-induced tumor incidence rate and tumor growth was also evidenced in PLC/PRF/5 cells when these cells were cotreated with 100 ng/mL rhFABP4 prior to subcutaneous injection into nude mice (Figure 7, E–G). This evidence concerns the gene FABP4 and neoplasm.
