Objective: To investigate the mechanism of TRAF4 mediated colon cancer cells proliferation. Methods:Colon cancer cells proliferation were tested by MTS and soft agar assayin sh-Mock and sh-TRAF4 stable cell lines. West-ern blot was conducted to detect the signaling transduction and the expression of Hexokinase II. Then the levels of glycol-ysis were assessed via measurement of glucose consumption and lactate production, respectively. The sensitivity of these stable cells to 5-Fu was detected by Western blotting. Results:Knockdown TRAF4 attenuates human colon cancer cells anchorage-dependent and -independent growth, TRAF4 knocking down inhibits EGF-induced Akt activation, as well as glycolysis and Hexokinase II expression. Moreover, knockdown TRAF4 increases the sensitivity of colon cancer cells to 5-Fu treatment. Conclusion: TRAF4 affects human colon cancer cells proliferation via glycolysis regulation.
