1 Nickel-induced cell death and survival pathways in cultured renal proximal tubule cells: roles of reactive oxygen species, ceramide and ABCB1. Nickel ATP binding cassette subfamily B member 1 Canis lupus familiaris
2 Here, we investigated the role of ABCB1 in nickel-induced stress signaling mediated by reactive oxygen species (ROS) and ceramides. Nickel ATP binding cassette subfamily B member 1 Canis lupus familiaris
3 ABCB1 protects against nickel toxicity as PSC833, an ABCB1 blocker, augmented the decrease in cell viability by nickel. Nickel ATP binding cassette subfamily B member 1 Canis lupus familiaris
4 ABCB1 protects against nickel toxicity as PSC833, an ABCB1 blocker, augmented the decrease in cell viability by nickel. Nickel ATP binding cassette subfamily B member 1 Canis lupus familiaris
5 ABCB1 protects against nickel toxicity as PSC833, an ABCB1 blocker, augmented the decrease in cell viability by nickel. Nickel ATP binding cassette subfamily B member 1 Canis lupus familiaris
6 Moreover, nickel toxicity was attenuated in renal MDCK cells stably overexpressing ABCB1. Nickel ATP binding cassette subfamily B member 1 Canis lupus familiaris
7 In conclusion, nickel induces a ROS-ceramide pathway to cause apoptotic cell death as well as activate adaptive survival responses, including upregulation of ABCB1, which improves cell survival by extruding proapoptotic (glucosyl)ceramides. Nickel ATP binding cassette subfamily B member 1 Canis lupus familiaris
