摘要:

根据扩展莫尼茨绦虫转录组测序结果,选取在虫体不同发育节片(即头颈节、幼节、成节和孕节)差异表达的10个基因KIFC1、Kif17、SmadD、β转录生长因子、β转录生长因子受体、HSD5、嘌啉毒素胺基肽酶、甲硫氨酸胺基肽酶2, 以及转录因子fork和Sox,利用实时定量PCR技术验证上述基因在扩展莫尼茨绦虫各发育阶段节片中mRNA转录情况。结果表明,与靶标基因在虫体头颈节的转录水平相比,KIFC1,Kif17基因在幼节的表达呈明显的上调趋势(P<0.01)。KIFC1、Kif17、β转录生长因子受体和嘌啉毒素胺基肽酶基因在成节的表达呈上调趋势(P<0.01)。HSD5、β转录生长因子受体和甲硫氨酸胺基肽酶2基因在孕节的表达呈上调趋势(P<0.01)。

Abstract:

According to the results of transcriptome sequencing in Moniezia expansa, 10 functional genes which represent different expression patterns in different developmental proglottids were selected, including KIFC1, Kif17, tgf-beta, SmadD, tgf-beta receptor, HSD5, aminopeptidase puromycin, Methionine aminopeptidase 2, transcription factor fork head and Sox transcription factor. A real-time fluorescent quantitative PCR assay was developed for detection of mRNA expression level of these taget genes with its beta-tubulin as an internal control. The results showed that compared to scolex-neck proglottids, the mRNA levels of 2 genes(KIFC1, Kif17) in immature proglottides, 4 genes(KIFC1, Kif17, tgf-beta receptor, and aminopeptidase puromycin) in mature proglottides, and 3 genes(HSD5, tgf-beta receptor, and Methionine aminopeptidase 2) in gravid proglottides were up-regulated (P<0.01).
