1 Genetic disruption of Abl nuclear import reduces renal apoptosis in a mouse model of cisplatin-induced nephrotoxicity. Cisplatin c-abl oncogene 1, non-receptor tyrosine kinase Mus musculus
2 We show here that cisplatin-induced apoptosis is defective in the renal proximal tubule cells (RPTC) from the Abl(mu/mu) mice. Cisplatin c-abl oncogene 1, non-receptor tyrosine kinase Mus musculus
3 When injected with cisplatin, we found similar levels of platinum in the Abl(+/+) and the Abl(mu/mu) kidneys, as well as similar initial inductions of p53 and PUMAalpha expression. Cisplatin c-abl oncogene 1, non-receptor tyrosine kinase Mus musculus
4 When injected with cisplatin, we found similar levels of platinum in the Abl(+/+) and the Abl(mu/mu) kidneys, as well as similar initial inductions of p53 and PUMAalpha expression. Cisplatin c-abl oncogene 1, non-receptor tyrosine kinase Mus musculus
5 Co-treatment of cisplatin with the Abl kinase inhibitor, imatinib, reduced the accumulation of p53 and PUMAalpha in the Abl(+/+) but not in the Abl(mu/mu) kidneys. Cisplatin c-abl oncogene 1, non-receptor tyrosine kinase Mus musculus
6 Co-treatment of cisplatin with the Abl kinase inhibitor, imatinib, reduced the accumulation of p53 and PUMAalpha in the Abl(+/+) but not in the Abl(mu/mu) kidneys. Cisplatin c-abl oncogene 1, non-receptor tyrosine kinase Mus musculus
7 Co-treatment of cisplatin with the Abl kinase inhibitor, imatinib, reduced the accumulation of p53 and PUMAalpha in the Abl(+/+) but not in the Abl(mu/mu) kidneys. Cisplatin c-abl oncogene 1, non-receptor tyrosine kinase Mus musculus
8 These results provide in vivo evidence for the pro-apoptotic function of Abl, and show that its nuclear localization and tyrosine kinase activity are both required for the sustained expression of p53 and PUMAalpha in cisplatin-induced renal apoptosis. Cisplatin c-abl oncogene 1, non-receptor tyrosine kinase Mus musculus
