Fig. 2. The expression of SPHK1 and TRAF6 in CRC cells.
A The efficiency of SPHK1 overexpression and knockdown was measured by western blot (left). The changes in the expression of TRAF6 level following SPHK1 overexpressed or down-regulated in HT29 or RKO cells identified by western blot (right). B Immunofluorescence assay revealed that SPHK1 regulated the level of TRAF6. Scale bar, 100 µm. Data were presented by mean with SD (n ≥ 3). *P < 0.05, **P < 0.01.
