BPA exposure impairs NMJ integrity. (a) Representative images of α-bungarotoxin (post-synaptic terminal) and synpatotagmin 2 (pre-synaptic terminal) labeling in wild type embryos at 48 hpf exposed to BPA vehicle control, or control media. Inset magnifications are merged images of the pre- and post-synaptic terminals. SC, spinal cord. (b) Data are based on the integrity of the NMJ at 48 hpf in control, vehicle control and BPA exposed embryos as measured by Pearson’s R2 co-localization coefficient between α-bungarotoxin and synaptotagmin 2. P = 0.02, N = 8–15 biological replicates; P = 0.006, N = 15 biological replicates; N = 5–6 technical replicates of motor neurons. P values were determined by Mann-Whitney U test.
