“…CBX and 18βGA have been reported to collapse the mitochondrial membrane potential (ΔΨ M ) (Salvi et al, 2005; Wang, Wong, Feng, & Zhang, 2014). Collapse of ΔΨ M has widespread effects on cell function, including on the regulation of IP 3 ‐evoked Ca 2+ release (Alexander, Kelly et al, 2019; Correa et al, 2011; Csordas et al, 2006; Narayanan, Xi, Pfeffer, & Jaggar, 2010; Olson, Chalmers, & McCarron, 2010; Rizzuto, Brini, Murgia, & Pozzan, 1993; Rizzuto et al, 1998; Sward, Dreja, Lindqvist, Persson, & Hellstrand, 2002; Szado et al, 2003). To determine if the ΔΨ M was altered by the drugs, mitochondria were visualised using the membrane potential indicator TMRE (120 nM, 5 min; Figure 9a) and the effects of CBX and 18βGA on ΔΨ M were examined.…”
