1 Cabozantinib reverses multidrug resistance of human hepatoma HepG2/adr cells by modulating the function of P-glycoprotein. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
2 This study assessed the mechanistic effect of cabozantinib on the reversal of P-glycoprotein (P-gp)-mediated multidrug resistance (MDR). cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
3 This study assessed the mechanistic effect of cabozantinib on the reversal of P-glycoprotein (P-gp)-mediated multidrug resistance (MDR). cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
4 The binding mechanism of cabozantinib to P-gp at the molecular level was evaluated using docking analysis. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
5 RESULTS: Cabozantinib enhanced the cytotoxicity of P-gp substrate drugs in HepG2/adr and HEK293-MDR1 cells but had no effect on non-P-gp substrates. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
6 In addition, cabozantinib increased the accumulation of P-gp substrates in HepG2/adr cells but had no effect in HepG2 cells. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
7 Furthermore, cabozantinib did not alter the expression of P-gp mRNA or protein but did stimulate the activity of P-gp ATPase. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
8 The docking study indicated that cabozantinib and verapamil may partially share a binding site on P-gp. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
9 Significantly, cabozantinib increased the inhibitory efficacy of doxorubicin in P-gp-overexpressing HepG2/adr cell xenografts in nude mice. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
10 CONCLUSION: Cabozantinib reverses P-gp-mediated MDR by directly inhibiting the efflux function of P-gp, indicating that cabozantinib may help to reverse P-gp-mediated MDR in HCC and other cancer chemotherapy. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
11 CONCLUSION: Cabozantinib reverses P-gp-mediated MDR by directly inhibiting the efflux function of P-gp, indicating that cabozantinib may help to reverse P-gp-mediated MDR in HCC and other cancer chemotherapy. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
12 CONCLUSION: Cabozantinib reverses P-gp-mediated MDR by directly inhibiting the efflux function of P-gp, indicating that cabozantinib may help to reverse P-gp-mediated MDR in HCC and other cancer chemotherapy. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
13 CONCLUSION: Cabozantinib reverses P-gp-mediated MDR by directly inhibiting the efflux function of P-gp, indicating that cabozantinib may help to reverse P-gp-mediated MDR in HCC and other cancer chemotherapy. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
14 CONCLUSION: Cabozantinib reverses P-gp-mediated MDR by directly inhibiting the efflux function of P-gp, indicating that cabozantinib may help to reverse P-gp-mediated MDR in HCC and other cancer chemotherapy. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
15 CONCLUSION: Cabozantinib reverses P-gp-mediated MDR by directly inhibiting the efflux function of P-gp, indicating that cabozantinib may help to reverse P-gp-mediated MDR in HCC and other cancer chemotherapy. cabozantinib ATP binding cassette subfamily B member 1 Homo sapiens
