中华鳖7种组织SOX基因表达的RT-PCR分析 总被引:3,自引:0,他引:3
In this paper, RT PCR analysis on SOX gene of seven tissues from the Chinese soft shelled turtle (Pelodiscus sinensis) was studied, and SOX gene fragments of expression from the testicle, brain, heart, kidney and spleen were cloned using RT PCR products.The results show that SOX genes has specific expression in the testicle, brain, spleen, cardiac muscle and kidney and isn't expression in muscle, liver and ovary of femel.The results of sequence reveal that the SOX genes of expression in the testicle are TSSOX1、TSSOX4 TSSOX5 and TSSOX9, and those are TSSOX2 and TSSOX4 in the brain, and this is TSSOX4 in the spleen and heart tissue, and those are TSSOX2 and TSSOX3 in the kidney tissue.This suggests that the SOX gene act important role not only on the sex determination, but also on the development of neural system, immunocyte system and the differentiation of male germ cell. 相似文献

本文分析了锯缘摄龟和齿缘摄龟的核型与Ag-NORs,结果:2FKn均为52,核型模式9+5+12。但锯缘摄龟AN=78, 其NOR位于A组No.4的长臂上,而齿缘摄龟AN=76,NOR位于A组的No.7的长臂。作者对这两种摄龟核型的结构特点和NOR位置差异的细胞分类学意义进行了讨论。G[2]G[-2]
Abstract:In this paper, the karyotypes and Ag-NORs of FKPyxidea mouhtiiand FKCyclemys dentatafrom China were studies. It was found that the 2FKn=52, the karyotypic formula is 9+5+12 in this two species. But FKP. mouhtiihas AN=78, its NORs located on the No.4 q of group A, while AN=76, NORs located on No.7 q of group A in FKC. dentata. The cytotaxonomical value of the features of karyotypic structure and the positinal differentiation of NORs between this two spepies is preliminarily discussed. 相似文献

中华鳖4个Sox基因保守区的序列分析 总被引:14,自引:2,他引:12
采用PCR技术,扩增和克隆了中华鳖Sox基因(TSSox)。经DNA序列分析显示,Sox基因在系统进化上十分保守,其中TSSox4与鸟类LF4基因编码的氨基酸序列完全相同、与人类SOX4和Sox4编码的序列仅一个氨基酸的差异;TSSox5与鸟类的LF5基因的编码也仅一个氨基酸发生了改变;TSSox2与海龟的TSox2相似性最高。4条TSSox序列中,TSSox与人SRY基因序列相似性最高,达75%;序列上的相似性可能暗示了它们在功能上的保守性。 相似文献

三种龟类动物的细胞遗传研究 总被引:2,自引:0,他引:2
本文以外周血淋巴细胞为材料,首次报道马来闭壳龟和地龟的核型,G带,C带和Ag-NORs,以及平胸龟的G带和C带,发现平胸龟的核型与前人报道的有差异。研究结果表明:平胸龟2n=54(14M+4ST+8T+28m),N.F.=72,7+6+14。A组No.6q per有一次缢痕。Ag-NORs位于A组的No.7 q ter。其全部染色体的着丝粒区均显示阳性C带,并且A组的No.7整条异染色质化;马来闭 相似文献
