摘要: 目的 研究斑马鱼甲状腺肿大疾病的原因,进一步探究疾病的发生是否由于缺碘引起。方法 取斑马鱼下颚部肿大组织,对病变组织进行HE染色和透射电子显微镜观察。同时设立了有碘饲养和无碘饲养组,在不同时期检测甲状腺相关的5个基因表达情况。结果 根据HE染色,诊断该疾病为甲状腺肿大;通过透射电子显微镜观察,发现病变组织存在线粒体肿大和溶酶体增多的现象。受精后7 d (7dpf) 胚胎的促肾上腺皮质激素释放因子(CRF)基因表达,有碘组显著高于无碘组(P<0.05)。结论 缺碘会引起斑马鱼甲状腺肿大及CRF基因表达量降低。

Abstract: Objective To investigate the causes of goiter in zebrafish, and explore whether the disease is caused by iodine deficiency. Methods The enlarged tissue in the lower jaw of zebrafish was observed through HE staining and electron microscopy. Meanwhile, both iodine-fed and iodine-free feeding groups were set up, and the expressions of five thyroid-related genes were detected at different periods. Result According to HE staining, goiter was confirmed. Through electron microscopy observation, the mitochondria was enlarged and lysosomes was increased in the diseased tissues. The expression of corticotropinreleasing factor (CRF) was different between the two groups at 7 days post fertilization (7dpf). The expression of CRF in iodine group was significantly higher than that in non-iodine group. Conclusion Iodine deficiency can cause goiter in zebrafish,iodine deficiency causes a decrease in CRF expression.
