The largest changes induced by HF/DDE were seen in down-regulated genes, such as galanin (Gal; −4.92-fold), cholinergic receptor nicotinic alpha 3 (Chrna3; −3.20-fold), somatostatin (Sst; −2.88-fold), neuromedin U (Nmu; −2.75-fold) or neuropeptide Y (Npy; −1.78-fold). Here, NPY is linked to hydrops fetalis.
