N1 - Funding Information:
We would like to dedicate this study to Pamela Roberts, the late Charity Director of the PPR Foundation, and to her late husband Peter, who passed away from a brain tumor. This study was financially supported by the PPR Foundation. The Cloudbuster-associated work was funded by the IBIN network. M.M. would like to thank the Luxembourg National Research Fund (FNR) for grant support (FNR PEARL P16/BM/11192868). The University of Huddersfield ICF Funds, United Kingdom, also financially contributed to this work. We would like to thank Dr Teklu Egnui for technical assistance.

N2 - Cancer cells undergo morphological changes and phenotype switching to promote invasion into healthy tissues. Manipulating the transitional morphological states in cancer cells to prevent tumor dissemination may enhance survival and improve treatment response. We describe two members of the RhoGTPase activating protein (ARHGAP) family, ARHGAP12 and ARHGAP29, as regulators of transitional morphological states in glioma via Src kinase signaling events, leading to morphological changes that correspond to phenotype switching. Moreover, we establish a link between glycogen synthase kinase 3 (GSK-3) inhibition and β-catenin translocation in altering transcription of ARHGAP12 and ARHGAP29. Silencing ARHGAP12 causes loss of N-cadherin and adoption of mesenchymal morphology, a characteristic feature of aggressive cellular behavior. In patients with glioblastoma (GBM), we identify a link between ARHGAP12 and ARHGAP29 co-expression and recurrence after treatment. Consequently, we propose that further investigation of how ARHGAPs regulate transitional morphological events to drive cancer dissemination is warranted.
