Figure Lengend Snippet: Effect of chemical hypoxia on cell surface TASK-1 localization. (A) The top panel shows nuclear staining with Hoechst 33342 (blue) and membrane labeling with WGA (red) in cells that express TASK-1-GFP. The lower panels present representative fluorescence images of TASK-1 from cells that were transfected with TASK-1-GFP treated with NaCN and/or BIM. Scale bar indicates 10 µm. (B) Summary of the intensity of TASK-1 fluorescence which was measured in the periphery of cells that express TASK-1-GFP. Cells were treated with NaCN, BIM, or both. Results are normalized to the control group. Experiments were conducted 3 times. (C) Diagram illustrating TASK-1 membrane topology with an extracellular HA tag used for chemiluminescence measurements. (D) Measurement of plasma membrane chemiluminescence of TASK-1 in cells treated with NaCN, BIM, or a combination. Data were normalized to control values and obtained from 3 separate experiments. *p < 0.05, **p < 0.01, ***p < 0.001.
