    Baclofen suppresses the glycogen synthase kinase 3/β-catenin and signal transducer and activators of transcription 3 pathways. A and B: Phosphorylation of glycogen synthase kinase 3 (GSK3) and signal transducer and activators of transcription 3 is decreased after baclofen treatment in both cholangiocarcinoma cell lines, both cultured in normal glucose and high glucose conditions. Total β-catenin protein is also decreased consistently with the decreased phosphorylated GSK3α/β. Western blots show the representative of three biological replications with the same trends of results. Band intensities are the average of three biological replications which are normalized using the intensities of glyceraldehyde-3-phosphate dehydrogenase for each experiment. The levels of phosphorylated forms are normalized with the total forms of their corresponding proteins. NG: Normal glucose; HG: High glucose; GAPDH: Glyceraldehyde-3-phosphate dehydrogenase; GSK3: Glycogen synthase kinase 3; STAT3: Signal transducer and activator of transcription 3.

    Schematic summary of the effects of high glucose on γ-aminobutyric acid B2 receptor expression and the effects of baclofen on cholangiocarcinoma cells. High glucose induces the expression of γ-aminobutyric acid B2 receptor (GABBR2) in cholangiocarcinoma (CCA) cells. The treatment of baclofen, a GABBR2 agonist, to CCA cells inhibits phosphorylation of glycogen synthase kinase 3, resulting in the activation of the kinase activity which further phosphorylates β-catenin. Phosphorylated β-catenin is subjected to degradation preventing its function on promoting cell proliferation via c-Myc and cyclin D1 expression. On the other hand, activated GABBR2 by baclofen also inhibits phosphorylation of signal transducer and activator of transcription 3 (STAT3). The inhibition of STAT3 phosphorylation also suppresses its functions as a transcription factor for c-Myc and cyclin D1 expression. Activating GABBR2 by baclofen, thus, suppresses the proliferation of CCA cells. GABBR2: γ-aminobutyric acid B2 receptor; GSK3: Glycogen synthase kinase 3; STAT3: Signal transducer and activator of transcription 3.

    Schematic summary of the effects of high glucose on γ-aminobutyric acid B2 receptor expression and the effects of baclofen on cholangiocarcinoma cells. High glucose induces the expression of γ-aminobutyric acid B2 receptor (GABBR2) in cholangiocarcinoma (CCA) cells. The treatment of baclofen, a GABBR2 agonist, to CCA cells inhibits phosphorylation of glycogen synthase kinase 3, resulting in the activation of the kinase activity which further phosphorylates β-catenin. Phosphorylated β-catenin is subjected to degradation preventing its function on promoting cell proliferation via c-Myc and cyclin D1 expression. On the other hand, activated GABBR2 by baclofen also inhibits phosphorylation of signal transducer and activator of transcription 3 (STAT3). The inhibition of STAT3 phosphorylation also suppresses its functions as a transcription factor for c-Myc and cyclin D1 expression. Activating GABBR2 by baclofen, thus, suppresses the proliferation of CCA cells. GABBR2: γ-aminobutyric acid B2 receptor; GSK3: Glycogen synthase kinase 3; STAT3: Signal transducer and activator of transcription 3.

Phosphorylated β-catenin is subjected to degradation preventing its function on promoting cell proliferation via c-Myc and cyclin D1 expression. On the other hand, activated GABBR2 by baclofen also inhibits phosphorylation of signal transducer and activator of transcription 3 (STAT3). The inhibition of STAT3 phosphorylation also suppresses its functions as a transcription factor for c-Myc and cyclin D1 expression. Activating GABBR2 by baclofen, thus, suppresses the proliferation of CCA cells. GABBR2: γ-aminobutyric acid B2 receptor; GSK3: Glycogen synthase kinase 3; STAT3: Signal transducer and activator of transcription 3.

    doi: 10.1083/jcb.202206078

    Figure Lengend Snippet: FAK is downregulated and CRKII-DOCK180/RacGEF exhibits increased interaction with unphosphorylated Y118-Paxillin in vivo compared to in vitro. (A) Schematic of in vitro Paxillin regulation from cell culture studies. Following integrin activation, a tyrosine kinase, FAK, phosphorylates Paxillin. Phosphorylated Paxillin then recruits the adaptor protein CRKII and the Paxillin/CRKII complex further recruits DOCK180/RacGEF, thereby activating downstream Rac-dependent pathways, inducing cell migration. (B) Western blot analysis of FAK levels (FAK) and FAK activation (pY397-FAK) in YUMM1.7 cells expressing mammalian WT-Paxillin-T2A-GFP in culture and YUMM1.7 tumors in vivo. In vitro and in vivo bands are from the same blot. Unmodified Western blot is in . GFP was used as the loading control and as a control for the number of YUMM1.7 cells in mouse tumors. (C and D) Quantification of the pY397-FAK/total FAK ratio (C) and total normalized FAK to GFP expression (D) in the in vitro cell culture and in vivo conditions. n = 3 dishes, 5 tumors for C, n = 5 dishes, 8 tumors for D. Error bars are mean ± SD. Non-parametric unpaired t test. (E) Western blot analysis of pY118-Paxillin levels in YUMM1.7 cells overexpressing GFP-FAK in vitro and in vivo. Actin is used as a loading control. (F) Quantification of pY118-Paxillin/Paxillin levels in E. GFP control tumors are normalized to 1. n = 4 technical replicates. Error bars are mean ± SD. Non-parametric unpaired t test. (G–J) Co-immunoprecipitation analyses of CRKII and Paxillin in YUMM1.7 cell lines that exogenously express mammalian wildtype, Y118E and Y118F Paxillin in vitro (G and H) and in in vivo tumors (I and J). (H and J) Quantification of CRKII/Paxillin ratio from G and I, bands from cells expressing wildtype Paxillin are normalized to 1 both in vitro and in vivo. n = 3 technical replicates. Non-parametric one-way ANOVA, error bars are mean ± SD. (K) Coimmunoprecipitation analyses of DOCK180/RacGEF and Paxillin in YUMM1.7 cell lines that exogenously express mammalian wildtype, Y118E and Y118F Paxillin in vitro and in in vivo tumors. (L–N) Coimmunoprecipitation analyses of CRKII and DOCK180/RacGEF to Paxillin in YUMM1.7 cell lines that exogenously express wildtype Paxillin in in vitro and in in vivo tumors. (M) Quantification of CRKII/Paxillin levels in L. n = 4 tumors. (N) Quantification of DOCK180/Paxillin levels in L. n = 4 tumors. Error bars are mean ± SD. Non-parametric unpaired t test.
