Feeling a bit cagey: Morpholino‐based antisense reagents have been caged through oligonucleotide cyclization (see scheme), enabling photocontrol of gene expression in zebrafish embryos and larvae. Using these reagents, the timing of exocrine cell fate commitment in the developing pancreas has been examined.
感觉有点笼统:基于吗啉代的反义试剂已通过寡核苷酸环化(见方案)被笼子笼罩,从而能够对斑马鱼胚胎和幼虫中的基因表达进行光控制。使用这些试剂,已经检查了发育中的胰腺中外分泌细胞命运承诺的时间。
