SET7 interacts with HDAC6 and suppresses the development of colon cancer through inactivation of HDAC6.

ABSTRACT: SET7 is the first lysine methyltransferase and plays vital roles in tumorigenesis. This study aims to seek clinical value of SET7 in colorectal cancer (CRC) patients, along with its biological impact on cell proliferation and migration. In patients with CRC, the expression of SET7 in cancer tissue was significantly lower than that in adjacent tissue, and down-regulated SET7 was closely correlated with poor prognosis. Loss-of-function and gain-of-function studies indicated that SET7 inhibited cell proliferation and migration by acting on HDAC6 substrate in colon cancer cells. Besides, the co-immunoprecipitation assay showed that SET7 and HDAC6 can interact reciprocally. The interaction effect between SET7 and HDAC6 could significantly reduce cell viability, scratch healing rate, and migrate
