Figure Lengend Snippet: Choline dehydrogenase (CHDH) mediates c‐Jun activation to promote colorectal cancer (CRC) cell migration in vitro. (A, B) Activation of 39 kinases or key proteins were detected in RKO cells overexpressing CHDH or MCS using a human phosphokinase array. (C) Western blot analysis the expression of c‐Jun and p‐c‐Jun in CHDH knockdown or overexpression cells. (D, E) Representative immunohistochemistry (IHC) staining of CHDH and p‐c‐Jun in human CRC tissues and the correlation results were shown, scale bar: 50 µm. (F) Western blot analysis the expression of c‐Jun and p‐c‐Jun in CHDH overexpression cells treated with SP600125. (G) Wound‐healing assay images of RKO and LOVO expressing CHDH cells treated with DMSO (Ctrl) or SP600125 were shown. Scale bar: 50 µm. (H) Transwell assay images of RKO and LOVO expressing CHDH cells treated with DMSO (Ctrl) or SP600125 were shown. Scale bar: 50 µm. (I) Statistic results on wound closure in RKO and LOVO expressing CHDH cells treated with DMSO (Ctrl) or SP600125. ** p < 0.01, *** p < 0.001. (J) Statistic results on migrated cells in RKO and LOVO expressing CHDH cells treated with DMSO (Ctrl) or SP600125. *** p < 0.001. (K) Immunofluorescence assay to detect F‐actin rearrangement in RKO and LOVO expressing CHDH cells treated with DMSO (Ctrl) or SP600125 via phalloidin staining. Scale bar: 20 µm. (L) Western blot analysis the expression of epithelial–mesenchymal transition (EMT) markers in RKO and LOVO expressing CHDH cells treated with DMSO (Ctrl) or SP600125.
