Fig. 2 Loss-of-function studies show ppargc1a is necessary for proper PST and DL formation. (A) Exon map of zebrafish ppargc1a and the target sites (X) for morpholinos (MO) and the location of the ppargc1asa13186 mutant allele. (B) WISH images of 28 ss ppargc1asa13186 WT siblings (WT), ppargc1asa13186-/-, ppargc1a MO1 injected, and ppargc1asa13186-/- + ppargc1a cRNA illustrating the changes in PST (trpm7-purple, top) and DL (slc12a3-red, bottom) formation in the ppargc1asa13186-/- and ppargc1a morphants, and the subsequent rescue when ppargc1a cRNA was added to the ppargc1asa13186-/-. Scale bars = 100 μm. Absolute length measurements of the PST (C), and DL (D) segments. (E) ppargc1a expression in DMSO control (top) and 150 μM bezafibrate-treated (bottom) zebrafish at the 28 ss following vehicle or vehicle/drug addition at the 5 hpf stage. Scale bars = 65 μm. (F) Absolute length measurements of the ppargc1a expression domain at 28 ss in DMSO control and bezafibrate-treated embryos from panel E. (G) qRT-PCR results showing ppargc1a RNA expression levels in bezafibrate-treated samples compared to DMSO controls. Data are represented as ±SD, significant by t test, n.s. = not significant, ** = p < 0.01, *** = p < 0.001.
