动物的前部模式化是基于一组高度保守的转录因子,但在原口动物前部基因调控网络(aGRN)内的相互作用仍然是个谜。在这里,我们确定了红粉甲虫赤拟谷盗foxQ 2(Tc-foxQ 2)的直系同源物作为一种新的上游组件的aGRN。它是唇和高级大脑结构(即中央复合体和蘑菇体)发育所必需的。我们通过RNAi和热休克介导的错误表达揭示了Tc-foxQ 2相互作用。令人惊讶的是,Tc-foxQ 2和Tc-six 3相互激活,在aGRN的顶部形成了一个新的调节模块。我们的结果与海胆和刺胞动物的比较表明,foxQ 2已获得更多的上游功能在原口进化的aGRN。我们的发现扩展了对foxQ 2基因功能的认识,包括在表皮发育和中枢脑模式中的重要作用。foxQ 2和six 3在控制赤拟谷盗胚胎前部发育的基因网络的顶部形成调控模块。
Anterior patterning of animals is based on a set of highly conserved transcription factors but the interactions within the protostome anterior gene regulatory network (aGRN) remain enigmatic. Here, we identify the red flour beetle Tribolium castaneum ortholog of foxQ2 (Tc-foxQ2) as a novel upstream component of the aGRN. It is required for the development of the labrum and higher order brain structures, namely the central complex and the mushroom bodies. We reveal Tc-foxQ2 interactions by RNAi and heat shock-mediated misexpression. Surprisingly, Tc-foxQ2 and Tc-six3 mutually activate each other, forming a novel regulatory module at the top of the aGRN. Comparisons of our results with those of sea urchins and cnidarians suggest that foxQ2 has acquired more upstream functions in the aGRN during protostome evolution. Our findings expand the knowledge on foxQ2 gene function to include essential roles in epidermal development and central brain patterning. Summary: foxQ2 and six3 form a regulatory module at the top of the gene network governing anterior development of the Tribolium castaneum embryo.
