Tubulin Polymerization Promoting Protein Family Member 3 (TPPP3), a member of the TPPP protein family, has been reported to play important roles in initiation and progression of human cancers. However, the expression and underlying function of TPPP3 in colorectal cancer (CRC) have not yet been fully clarified. In this study, the mRNA and protein levels of TPPP3 in 96 clinical CRC specimens were determined by RT-PCR and immunohistochemistry. The relation between TPPP3 expression and clinicopathologic characteristics and overall survival (OS) were evaluated. Further experiments showed that knockdown of TPPP3 inhibited cell proliferation, migration and invasion and induced cell apoptosis in vitro. In addition, TPPP3 silencing resulted in a decrease of angiogenesis and S phase fraction. Thus, our results suggested that TPPP3 played an important role in CRC progress and might serve as novel therapeutic target for CRC treatment.
