1 1alpha,25-Dihydroxyvitamin D3 potentiates cisplatin antitumor activity by p73 induction in a squamous cell carcinoma model. Cisplatin transformation related protein 73 Mus musculus
2 Cisplatin has been shown to modulate p73 protein level in certain cancer cells. Cisplatin transformation related protein 73 Mus musculus
3 Our data showed that p73 level was not affected by cisplatin but increased by 1,25D3 in SCC cells. Cisplatin transformation related protein 73 Mus musculus
4 Knocking down p73 by small interfering RNA protected SCC cells against 1,25D3 and cisplatin-mediated clonogenic cell kill and apoptosis. Cisplatin transformation related protein 73 Mus musculus
5 Increasing p73 protein level by knocking down UFD2a, which mediates p73 degradation, promoted 1,25D3 and cisplatin-mediated clonogenic cell kill. Cisplatin transformation related protein 73 Mus musculus
6 These results suggest that 1,25D3 potentiates cisplatin antitumor activity in vitro and in vivo in a SCC model system possibly through p73 induction and apoptosis. Cisplatin transformation related protein 73 Mus musculus
