CPAAHTs exposure suppressed the expression of genes required for myocardium differentiation and LR asymmetry. (A,B) Dorsal view of WISH images (A) and quantitative RT-PCR analysis (B) of transcription factors nkx2.5, gata4, mef2ca, and tbx20 in 0.8 μg/μl CPAAHTs treated embryos compared with untreated controls at 8-somite stage (SS). Arrows point to expected expression patterns for the corresponding genes. N = 3. Unpaired 2-tailed Student’s t-test. (C,D) Dorsal view of WISH images (C) and quantitative RT-PCR analysis (D) of Nodal-related gene spaw and its downstream target genes in 0.8 μg/μl CPAAHTs treated embryos compared with untreated controls at 25- to 28-SS. Arrows point to the expected expression patterns for the corresponding genes. N = 3. Unpaired 2-tailed Student’s t-test.
