FzE3 Materials and Methods We analyzed RON and MET expression in 187 primary TNBC clinical samples with immunohistochemistry. We validated the targeted therapeutic effects of RON and MET in TNBC using three tyrosine kinase inhibitors (TKIs): BMS-777607, INCB28060, and tivantinib. The preclinical therapeutic efficacy of the TKIs was mainly estimated using a TNBC xenograft model. Results Patients with TNBC had widespread, abnormal expression of RON and MET. There was RON overexpression, MET overexpression, and RON and MET co-overexpression in 63 (33.7%), 63 (33.7%), and 43 SGC-CBP30 cases (23.0%), respectively, which had poor prognosis and short survival. and and em in vivo /em . On the other hand, INCB28060 was barely effective. Due to the multi-locus nature of small-molecule drugs, we believe that the anti-tumor effect of tivantinib is not MET-dependent and may be related to other targets. A recent study reported that the potent anti-tumor activity of tivantinib in hepatocellular carcinoma was achieved by targeting microtubules [32]. RON and MET can cross-talk and cooperate in intracellular signaling via transphosphorylation by forming specific RON-MET complexes [33]. This is consistent with the fact that the TKIs specifically targeting MET in the present study can slightly inhibit RON phosphorylation at cellular level. These SGC-CBP30 basic research studies have also laid the foundation for the joint inhibition of RON and MET in TNBC such as BMS-777607 and tivantinib. In summary, RON and MET are widely expressed in TNBC cancer tissues. This study demonstrates that RON and MET may be involved in an important process in TNBC malignant progression and can be important biomarkers in TNBC of poor prognosis. TKIs targeting RON and Met can inhibit the activation of the downstream signaling molecules, inhibit TNBC cell migration and proliferation, and increase TNBC cell apoptosis em in vitro /em ; in nude mouse xenograft models, the TKIs can significantly inhibit tumor growth and shrink tumor volume. TKIs targeting MET and RON have stronger medication advancement potential in TNBC treatment.
