Open golden hill to wait besides will many in-house natural resources on the net of dimensions swims besides the enterprise, for small network swims in the help the company undertakes poineering, established a net to swim before two years grandly industrial fund -- 18 fund, agree by royal network CEO in Chen Tianqiao guides tall canal to appear personally, listen attentively to taletelling of the person that do poineering work.

In this exper iment,we took the advantage of RNAi technique,microinjected tinman and singless dsRNA into the early embryos in Drosophila respectively and got these two genes' RNAi phenotypes,which were very similar to that of their mutant,showing heart tube defects or no heart precursors formation.tinman dsRNA eve caused visceral mesoderm defects and the somatic muscles disruption,yet wingless dsRNA only affected heart precursors and had no effect on visceral mesoderm and somatic muscles,indicationg that the heart-related genes dsRNA interference worked effectively and exclusively in Drosophila.

实验运用RNAi技术，分别将tinman和wingless的dsRNA注入果蝇的早期胚胎，得到了这两个基因的dsRNA干扰表型，与两个基因的突变体表型非常相似，都表现为果蝇心脏前体细胞不能形成或心脏管缺失。尤其是tinman基因的dsRNA，还引起了肠中胚层缺失和体壁肌肉组织的紊乱，而wingless基因的dsRNA却只影响心脏的形成，而不影响肠中胚层，说明dsRNA干扰具有非常强的特异性，因而不失为研究果蝇心脏发育基因功能的有效方法。
