Further analysis showed that, in tumors from mice injected with cisplatin or carboplatin, the protein levels of UBE2F and NOXA were positively and negatively correlated with tumor weight, respectively (UBE2F: cisplatin injection, Pearson R = 0.91, P = 0.0016; carboplatin injection, Pearson R = 0.84, P = 0.0091. This evidence concerns the gene PMAIP1 and neoplasm.
