Upregulation of the galanin receptor 2a/2b (galr2a/b) and serotonin-related genes in the brain upon overexpression of spx1 in the dHb. Quantitative RT-PCR in Tg(gpr151:gal4vp16);Tg(5xuas:spx1:p2a-mcherry) zebrafish (dHb-spx1 OV) and their wildtype siblings β-actin expression was used to normalize all samples, and data were acquired in triplicate. Data are represented as mean ± SEM (n = 3). (A) Relative galr2a and galr2b mRNA expression in the IPN (n = 10 per group): Galr2a: siblings, 1.003 ± 0.06386; dHb-spx1 OV, 66.78 ± 7.778. Galr2b: siblings, 1.03 ± 0.1803; dHb-spx1 OV, 83.17 ± 2.561. (B) Relative plasmacytoma expressed transcript 1 (pet1), tryptophan hydroxylase 2 (tph2), and slc6a4a mRNA expression in the brain (n = 5 per group): Pet1: siblings, 1 ± 0.03215; dHb-spx1 OV, 1.137 ± 0.03383. Tph2: siblings, 1 ± 0.005774; dHb-spx1 OV, 1.253 ± 0.03333. Slc6a4a: siblings, 1 ± 0.02517; dHb-spx1 OV, 1.047 ± 0.02848 [*p < 0.05, **p < 0.005, ****p < 0.0001 (Unpaired t-test), n.s., not significant].
