Zinc finger protein 382 (ZNF382), a member of the Krüppel-associated box zinc finger proteins (KRAB-ZFPs) family, plays critical roles in regulating certain downstream genes expression as a transcription inhibitor. ZNF382 is downregulated in multiple tumors due to hypermethylation of its promoter, to be more specific, methylation of promoter CpG island may contributes to inhibition of gene expression as found in many studies. With application of DNA methyltransferase inhibitors (DNMTi) 5-azacytidine and 5-aza-2'-deoxycytidine, hypomethylation of ZNF382 gene may contribute to anti-tumor effects. This review summerized the structure, biological functions, expression and the roles of ZNF382 in multiple cancers, and, expression of ZNF382 regulated by promoter methylation was further discussed to show the possibilities of DNA hypomethylation treatment as a potential treatment in clinical applications.
