Research on Effects of Cadmium Induced Intestinal Epithelial Cell Injury and Regulation on Intestinal Stem Cells Regeneration and Differentiation in Drosophila Mid-gut
Cadmium is a typical toxic heavy metal element,which is extremely harmful for people's health in environment.To explore the harmful mechanism of cadmium in digestive system,we use the Drosophila adult mid-gut,which is proved an excellent model to study tissue damage and intestinal stem cell(ISC) regulation mechanisms.In this work,the flies were fed with different concentrations of cadmium chloride.Cadmium over intake could induce ultra-structural damage in mid-gut epithelial cells,especially the nuclear mem...
重金属镉是当今世界热点关注的重要环境污染源之一,1993年,镉及其相关化合物被国际癌症研究会(International Agency for Research on Cancer,IARC)确认为第一致癌物。重金属污染能够通过吸入性粉尘和食物被摄入体内,由于其极难由体内排出,因此能够造成毒性的积累,最终导致严重
