Title	Zinc-dependent Zip7-MAZ-MYBL2 axis promotes prostate cancer metastasis
Description	Screening reveals that a zinc transporter Zip7 was upregulated in metastatic PCa and related to poor progression. Zip7 silencing inhibits PCa cell migration and invasion in vitro and bone-metastasis in vivo. Mechanistically, we identify that Zip7 mainly interacts with MAZ in cytoplasm to facilitate MAZ nuclear import and nuclear MAZ was up-regulated in metastatic prostate cancer tissues and positively associated with Zip7 expression, which promotes PCa bone metastasis. Furthermore, our RNA-seq studies reveal that Zip7 facilitates MAZ nuclear import to promote MYBL2 transcription. Strikingly, we show in intraarterial injected-bone metastasis xenograft model that targeting Zip7 by its inhibitor markedly suppressed PCa bone metastasis. Collectively, our findings identify Zip7 is an important regulator of PCa metastasis and targeting Zinc-dependent Zip7-MAZ-MYBL2 could be a valuable strategy to ameliorate advanced PCa metastasis.
