[求助] 很捉急 求大神

To further our understanding of FOG gene function during cardiac development, we utilized zebrafish to examine FOG’s role in the early steps
of heart morphogenesis. We identified fragments of three fog genes in the zebrafish genomic database and isolated full-length coding sequences
for each of these genes by using a combination of RT-PCR and 5V-RACE. One gene was similar to murine FOG-1 (fog1), while the remaining two
were similar to murine FOG-2 (fog2a and fog2b). All Fog proteins were able to physically interact with GATA4 and function as transcriptional corepressors.
Whole-mount in situ hybridization revealed fog1 expression in the heart, the hematopoietic system, and the brain, while fog2a and
fog2b expression was restricted to the brain. Injection of zebrafish embryos with a morpholino directed against fog1 resulted in embryos with a
large pericardial effusion and an unlooped heart tube. This looping defect could be rescued by co-injection of mRNA encoding murine FOG-1, but
not by mRNA encoding FOG-1 lacking the FOG repression motif. Taken together, these results demonstrate the importance of FOG proteins for
zebrafish cardiac development and suggest a previously unappreciated role for FOG proteins in heart looping that is dependent on the FOG
repression motif.

让我们进一步了解雾基因功能的心脏发育过程中,我们利用斑马鱼研究在早期步骤雾的作用心脏形态。我们发现在斑马鱼基因组数据库三雾基因片段和全长编码序列的分离为每个这些基因采用RT-PCR和5v-race组合。一个基因与小鼠FOG-1(Fog1),而剩下的两个类似于小鼠fog-2(fog2a和fog2b)。所有雾蛋白能够与GATA4和功能的转录抑制因子相互作用。整体原位杂交显示在心脏Fog1表达,造血系统,和大脑,而fog2a和fog2b表达被限制到大脑。以吗啉针对Fog1斑马鱼胚胎注射导致胚胎与大量心包积液和环运动心管。被编码小鼠FOG-1 mRNA的共注射救出这个循环的缺陷,但不通过编码FOG-1缺乏雾压抑主题mRNA。总之,这些结果表明,雾的蛋白质的重要性斑马鱼心脏发育和建议雾蛋白在心脏循环是依赖于雾先前赏识的作用压抑的主题。D 2005 Elsevier公司保留所有权利
