新华社东京6月23日电（记者钱铮）京都大学日前发布新闻公报说，该校和日本立命馆大学等机构的研 究人员发现，如果斑马鱼胚胎在发育初期同时接触双酚A和视黄酸，其大脑、神经和面部结构等的形成 过程中出现异常的风险会显著增加。 据公报介绍，近年来不孕症、生殖器官相关癌症等与内分泌系统异常相关的疾病以及过敏、肥胖、自闭 症等的增多被认为与内分泌干扰化学物质相关。其中有代表性的一种化学物质就是双酚A。双酚A通常 被用作塑料原料，还被广泛用于罐头涂层、超市小票等热敏纸。 此前的研究显示，双酚A可通过类固醇激素受体给生殖和内分泌系统带来不良影响。同时，流行病学调 查显示双酚A有可能影响大脑结构和行为等，但此类影响发生的机制尚不明确。同时，生物体内视黄酸 浓度受到精密调控，妊娠期间视黄酸不足或过量摄入均会导致胎儿形态异常。 据这项发表在美国《环境健康观察》月刊上的研究，团队利用人类诱导多能干细胞开展实验后发现， HOX基因具有调控生物形态形成的功能，如果单独添加双酚A不会对HOX基因的表达产生影响，而如 果同时添加低浓度的视黄酸，则HOX基因的表达大幅增加。 研究人员又用斑马鱼胚胎进行了同样实验，结果显示，如果斑马鱼胚胎同时暴 ...
