| Project Title: | GSK3 inhibits macropinocytosis and lysosomal activity through the Wnt destruction complex machinery |
| Project Summary: | Canonical Wnt signaling is emerging as a major regulator of endocytosis. Here we report that mutation of Axin1, a tumor-suppressor part of the β-catenin destruction complex, results in the activation of macropinocytosis in Alexander hepatocellular carcinoma (HCC) cells. Axin1 binds Glycogen Synthase Kinase 3 (GSK3), and we found that inhibition of GSK3 by Lithium chloride (LiCl), CHIR99021 or dominant-negative GSK3 triggered macropinocytosis. GSK3 inhibition caused a rapid increase in endolysosomes that was independent of new protein synthesis. GSK3 inhibition or Axin1 mutation increased lysosomal activity, which could be followed with tracers for active cathepsin D, β-glucosidase, and ovalbumin degradation. Microinjection of LiCl into the blastula cavity of Xenopus embryos caused a striking increase in dextran macropinocytosis. The effects of GSK3 inhibition on macropinocytosis and protein degradation in endolysosomes were blocked by the macropinocytosis inhibitors EIPA or IPA-2, suggesting that the increased membrane trafficking drives lysosomal activity and nutrient acquisition. |

Collection:
| Collection ID: | CO001389 |
| Collection Summary: | Extraction began by placing the 6-well dishes on ice and washing each well with 2mL of a 150 mM ammonium acetate solution (pH 7.4, 4°C). Post wash, metabolites were extracted from each well on dry ice with 500 μL of a (1:4) dH20, MeOH solution at -80°C. The samples were then incubated for 15 min at -80°C. Afterwards, the cells were scraped into solutions which were then transferred to eppitubes and spun down at 4°C for 10 min at 17,000g. The supernatants were transferred to new glass vials and dried with an EZ2-Elite lyophilizer (Genevac). These dried metabolites were then stored at -80°C until they could be run on the LC/MS. |
| Sample Type: | Cultured cells |
| Storage Conditions: | Described in summary |
Treatment:
| Treatment ID: | TR001409 |
| Treatment Summary: | The cells were incubated with DMEM(no glucose) supplemented with 10% dialyzed FBS, 1% P/S, and 10 mM UC13-glucose with either vehicle (0.1% BSA in dH20) or wnt (100ng/mL) added. Cells were treated for either 20 min or 60 min with each treatment group having a vehicle matched time control. |
