Physical growth and brain development need sufficient thyroid hormone (TH). This dataset describes serum T4 level, body weight gain and day of eye opening in offspring mice exposed to the TH synthesis inhibitor propylthiouracil (PTU) from gestational day (GD) 15 to postnatal day (PND) 25. This dataset also describes content of dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), 3-methoxytyramine (3-MT), 5-HT, and 5-hydroxyindoleacetic acid (5-HIAA) and their turnover in the hypothalamus, hippocampus, and nucleus accumbens of male offspring mice perinatally exposed to PTU. These data are referred by a research article entitled “Hyperactive behavioral phenotypes and an altered brain monoaminergic state in male offspring mice with perinatal hypothyroidism” [1].
