To discover the possible roles of ZNF217 as a novel prognostic biomarker for CRC and its regulation by miR-203 miRNA in CRC tissues and paired normal colorectal tissues, we carried out in vitro experiments and verified that 1) ZNF217 can promote proliferation, invasion and migration of CRC mobile strains and two) ZNF217 as effectively as its consequences in CRC cell strains are downregulated by miR-203, hoping to additional elucidate the system of CRC development and offer novel findings for targeted treatment of CRC.A complete of 82 CRC clients who underwent surgical resection of tumors for CRC among July 2004 and March 2009 in the Section of Standard Surgical treatment, Qilu Healthcare facility of Shandong University, Jinan, China, had been recruited for this examine.

A single review offers evidences that ZNFs are regulated at post-transcriptional stage in breast most cancers by miR-181a, which straight targets the coding regions of ZNFs [4].
