Article Title: Inhibition of PRMT1 Suppresses the Growth of U87MG-Derived Glioblastoma Stem Cells by Blocking the STAT3 Signaling Pathway
doi: 10.3390/ijms25052950
Figure Lengend Snippet: Effect of furamidine on proliferation of U87MG-derived GSCs in vitro and in vivo. ( A ) Protein expression levels of PRMT1 in U87MG adherent and tumorsphere cells. Protein levels were detected by Western blotting and quantified by densitometry. β-Actin levels were used as a loading control. * p < 0.05. ( B ) Effect of furamidine on the proliferation and tumorsphere formation in U87MG-derived GSCs. Cells were treated with furamidine at various concentrations (0–100 μM) for 7 days. Cell proliferation was measured using the CellTiter-Glo ® luminescent assay system. Formed tumorspheres were counted under an optical microscope. ** p < 0.005, *** p < 0.001 vs. the control. ( C ) Effect of furamidine on tumor growth derived by U87MG GSCs in a CAM model. U87MG-derived GSCs were mixed with ECM gel in the absence or presence of the furamidine (10 µg/egg) and placed onto the CAM surface of fertilized chick eggs. After incubation for 7 days, the size and weight of the formed tumors were calculated. * p < 0.05 vs. the control.
Article Snippet: Furamidine (PRMT1 inhibitor), berbamine (CaMKIIγ inhibitor), and colivelin (STAT3 activator) were purchased from Tocris (Bristol, UK), Sigma-Aldrich (St. Louis, MO, USA), and MedChemExpress (Monmouth Junction, NJ, USA), respectively.
