MCU OX causes mROS flashes and ΔΨm flickers in sheared ECs. (A) Characteristic temporal profiles of normalized mtSOX Deep Red fluorescence for each EC in a microscope image, where the monolayer was exposed to 1 min static followed by 9 min SS. (B) Same as in (A), but for Ad.MCU-transduced ECs. (C) Magnification of a ΔΨm transient (shown by a dotted box in B). (D) Characteristic TMRM fluorescence shows overlap with mito-GCaMP6 in an unstimulated EC. (E) F (in arbitrary units) averaged over an area of a cell (white box in D) for both mito-GCaMP6 and TMRM vs. time. (F) Magnification of the cell area (white box in D) shows opposing behavior between mito-GCaMP6 and TMRM at a single-mitochondrion level at time points 1–3 (time points shown in E).
