Fig. 3. The cortisol-mediated [(Ca²⁺)i] increase is independent of glucocorticoid receptor. (a) Representative images of the developing trunk muscle (DTM) loaded with the ratiometric dye FURA-2AM and treated with either vehicle (CONTROL), cortisol (CORT), RU486 or a combination of cortisol and RU486 (RU486+CORT), as well as cortisol treatment of the DTM from GRKO zebrafish (GRKO + CORT). (b) Graph showing the ratiometric FURA-2AM intensity in the DTM treated with either cortisol, RU486 or a combination of cortisol and RU486 at 30 s post-cortisol exposure. (c) Graph showing the ratiometric FURA-2AM intensity in wildtype or GR knockout (GRKO) DTM at 30 s post-cortisol addition. All bars represent mean ± SEM (n = 4–5 independent embryos); bars with different letters are significantly different; one-way ANOVA; Holm Sidak post hoc test; p < 0.05.
