Figure Legend Snippet: Loss of JNK1 promoted β-catenin protein expression and β-catenin-mediated transcriptional activity of TCF. (A) β-Catenin protein expression was upregulated in JNK1−/− MEFs. Both MEFs were lysed and subjected to immunoblotting analysis detecting the expression of β-catenin and JNK1. β-Actin was used as loading control. (B) β-Catenin–TCF4 reporter activity was upregulated in JNK1−/− MEFs. JNK1+/+ and JNK1−/− MEFs were cotransfected with Renilla and a construct of TOPFLASH or FOPFLASH. Twenty-four hours after transfection, cells were treated with Wnt3a condition medium of 1:4 dilution for 24 h and harvested for luciferase activity assay.
Techniques Used: Expressing, Activity Assay, Western Blot, Construct, Transfection, Luciferase
Figure Legend Snippet: Active JNK1 downregulated β-catenin expression and inhibited its transcriptional activity. (A) Active JNK1 reduced β-catenin protein level in HEK cell line HEK293T. HEK293T cells were cotransfected with pcDNA3-Flag-MKK7-JNK1 and pcDNA3-HA-β-catenin. Forty-eight hours after transfection, cells were harvested for immunoblotting analysis to detect the alterations of HA-β-catenin, p-JNK and p-c-Jun. β-Actin served as loading control. The density of band was quantified and the expression of β-catenin was normalized to β-actin. (B) Active JNK1 inhibited β-catenin-mediated transcriptional activity of TCF4. HEK293T cells were cotransfected with pcDNA3-Flag-MKK7-JNK1, pcDNA3-HA-β-catenin, TOPFLASH or FOPFLASH and a Renilla construct. Forty-eight hours after transfection, cells were harvested for luciferase activity assay. Each bar represents the mean ± SD for triplicate samples. Similar experiments were done in human colon cancer cell line SW480 (C and D). (E) Activated exogenous JNK1 reduced β-catenin protein level in a dose-dependent manner. HEK293T cells were cotransfected with pcDNA3-HA-β-catenin and different amounts of pcDNA3-Flag-MKK7-JNK1, as indicated. The protein was obtained for immunoblotting analysis to detect the alterations of HA-β-catenin and p-JNK. β-Actin served as loading control. (F) Activated exogenous JNK1 inhibited β-catenin-mediated transcriptional activity of TCF in a dose-dependent manner. HEK293T cells were cotransfected with pcDNA3-HA-β-catenin, TOPFLASH, Renilla, along with different amounts of pcDNA3-Flag-MKK7-JNK1, as indicated. Forty-eight hours after transfection, cells were harvested for luciferase activity assay. Each bar represents the mean ± SD for triplicate samples.
