在已确诊的人类癌症中,超过一半的原因是P53‘S正常功能缺失。我们鉴定了金属转运蛋白ZIP14(锌调节转运蛋白(ZRT)和铁调节转运蛋白(IRT)样蛋白14)是一种P53调节蛋白。P53缺失可上调ZIP14蛋白表达,P53表达增强可下调ZIP14蛋白表达。这种调节并不完全依赖于ZIP14‘S基因表达的变化。共沉淀研究表明,P53与ZIP14相互作用,并增加其泛素化和降解。此外,P53基因敲除导致非转铁蛋白结合铁摄取增加,这是通过增加ZIP14水平来调节的。我们的研究强调了P53在调节营养代谢中的作用,并提供了对铁以及其他金属(如锌和锰)如何在P53失活的肿瘤细胞中进行调节的见解。
Loss of p53’s proper function accounts for over half of identified human cancers. We identified the metal transporter ZIP14 (Zinc-regulated transporter (ZRT) and Iron-regulated transporter (IRT)-like Protein 14) as a p53-regulated protein. ZIP14 protein levels were upregulated by lack of p53 and downregulated by increased p53 expression. This regulation did not fully depend on the changes in ZIP14’s mRNA expression. Co-precipitation studies indicated that p53 interacts with ZIP14 and increases its ubiquitination and degradation. Moreover, knockdown of p53 resulted in higher non-transferrin-bound iron uptake, which was mediated by increased ZIP14 levels. Our study highlights a role for p53 in regulating nutrient metabolism and provides insight into how iron and possibly other metals such as zinc and manganese could be regulated in p53-inactivated tumor cells.
