dsRNA Uptake In article 2100064 by Kristen A. Panfilio and co-workers, the cuticle exoskeleton of flour beetle larvae reveals normal anatomy (above: head-to-tail in blue-to-red) and long-term parental RNAi knockdown (below), here showing a mirror-image duplication of the abdomen (red termini to yellow center). Strong knockdown can persist for months despite transmission of full-length double-stranded RNA (dsRNA) from the mother into the egg, depleting maternal dsRNA levels.
双链RNA摄取 在克里斯汀·A·潘菲利奥及其同事发表的第2100064号文章中,面粉甲虫幼虫的角质层外骨骼显示出正常的解剖结构(上图:从蓝色头部到红色尾部)和长期的亲代RNA干扰敲低(下图),此处显示腹部的镜像重复(从红色末端到黄色中心)。尽管全长双链RNA(dsRNA)从母体传递到卵中,导致母体dsRNA水平耗尽,但强烈的敲低仍可持续数月。
