Activation of β-catenin pathway by BIO. In order to evaluate the activation of the β-catenin pathway, hMADS cells were nucleofected as described in Zaragosi et al. [14] with a plasmid carrying firefly luciferase under the control of a Tcf/Lef response element (TopLuc). An inactive version of the response element was used as a control (FopLuc). Twenty four hours after nucleofection, cells were treated with BIO and 24 h after BIO treatment, cells were analyzed for luciferase expression. Renilla luciferase was co-nucleofected and used for normalization. Data indicated that β-catenin pathway was activated in hMADS cells after inhibiting GSK3.

Morphology of hMADS3 cells after treatment with GSK3 inhibitors. Cells were maintained in medium supplemented with 0.5% FCS in the absence (Control) or presence of 0.5 μM BIO or 20 mM LiCl for 5 days.

Impact on differentiation of GSK3 inhibition during cell proliferation. hMADS cells were maintained in the absence or presence of BIO or MeBio for 5 days. Then, cells were collected and plated at high cell density without any GSK3 inhibitor. Two days after cells reached confluence and were induced to undergo differentiation into adipocytes. GPDH activity was quantified seven days after induction of differentiation.
