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......閱讀全文

CDH2基因突變與藥物因子介紹
這個基因編碼一個典型的鈣粘蛋白和鈣粘蛋白超家族的成員。選擇性剪接導致多個轉錄變體，其中至少一個編碼前蛋白，經蛋白質水解處理后生成鈣依賴性細胞粘附分子和糖蛋白。這種蛋白質在左右不對稱的建立、神經系統的發育以及軟骨和骨的形成中起作用。[由RefSeq提供，2015年11月]This gene encod
