To investigate molecular and cellular mechanisms of central pattern generators (CPG) functioning, we previously selected candidate genes mutations of which are accompanied with deviations in Drosophila melanogaster motor activity. In this research we tested locomotor parameters in lines with post transcriptional silencing of 12 candidate gene in Drosophila central nervous system. Silencing was provided by synthesis of interfering RNA by means of GAL4/UAS system under control of CNS-specific gene promoters (elav, nrv2, appl, tsh). It was found that RNA interference of most genes are accompanied with changes in one or several locomotor parameters. Pattern of revealed deviations under control of different promotors makes it possible to determine the genes that activity in nervous system is necessary for proper functioning of locomotor CPG.
为了研究中枢模式发生器(CPG)功能的分子和细胞机制,我们之前筛选了一些候选基因,这些基因的突变会伴随着黑腹果蝇运动活性的偏差。在本研究中,我们测试了果蝇中枢神经系统中12个候选基因转录后沉默品系的运动参数。通过GAL4/UAS系统在中枢神经系统特异性基因启动子(elav、nrv2、appl、tsh)的控制下合成干扰RNA来实现基因沉默。结果发现,大多数基因的RNA干扰都伴随着一个或几个运动参数的变化。在不同启动子控制下所揭示的偏差模式,使得确定那些在神经系统中的活性对于运动CPG的正常功能所必需的基因成为可能。
