Figure Lengend Snippet: GLS1-mediated glutamine metabolism maintains cell proliferation by providing proliferative response substrates. ( A ) Representative bright-field images of liver organoids before (upper panel) and after (lowing panel) the treatment with or without CB839 and NEAA for 48 h (Bar = 1000 μm) and the quantification of organoid size ( B ). ( C ) Cell viability measurement was performed using presto blue. Relative cell viability was calculated by normalizing to Control after 48 h of incubation ( n = 5). ( D ) Protein synthesis in liver organoids treated with or without CB839 and NEAA for 48 h was determined by L-homopropargylglycine (HPG) mean fluorescence intensity (MFI), ( n = 5). (E) Proliferation of liver organoids treated with or without CB839 and NEAA for 3 h was determined by BrdU incorporation, ( n = 5). All data are means ± SEM. ∗ P < 0.05, ∗∗ P < 0.01, one-way ANOVA was used
Article Snippet: Rescue experiments were performed with 5 mM glutathione reduced ethyl ester (GSH-EE), 1x MEM Non-Essential Amino Acids solution (NEAA) from Thermo Fisher Scientific.
Techniques: Control, Incubation, Fluorescence, BrdU Incorporation Assay
