Determiningtheeffectsofnicotineonboneinchicks
ObjectiveThe purpose of this experiment is to determine how the development of bone and cartilage in a chick are affected by treating the embryo with nicotine at early stages of development.IntroductionMaternal smoking during pregnancy has long been recognized as a hazard, increasing the incidence of premature delivery, spontaneous abortion, low birth weight, and neonatal mortality. There is also an increase in the o......阅读全文

CDH2基因突变与药物因子介绍
这个基因编码一个典型的钙粘蛋白和钙粘蛋白超家族的成员。选择性剪接导致多个转录变体，其中至少一个编码前蛋白，经蛋白质水解处理后生成钙依赖性细胞粘附分子和糖蛋白。这种蛋白质在左右不对称的建立、神经系统的发育以及软骨和骨的形成中起作用。[由RefSeq提供，2015年11月]This gene encod
