We have analyzed the expression patterns of two Fox genes, FoxE and FoxQ, in the ascidian Ciona intestinalis. Expression of Ci-FoxE was specific to the endostyle of adults, being prominent in the thyroid-equivalent region of zone 7. Ci-FoxQ was expressed in several endodermal organs of adult ascidians, such as the endostyle, branchial sac and esophagus. In the endostyle, the pattern of Ci-FoxQ expression was similar to that of CiTTF-1, being prominent in the thyroid-equivalent regions of zones 7 and 8. Therefore, these Fox genes may perform thyroid-equivalent functions in the ascidian endostyle.
我们分析了海鞘Ciona intestinalis中两个Fox基因FoxE和FoxQ的表达模式。Ci-FoxE的表达在成体的内柱中具有特异性，在7区的甲状腺等效区域尤为显著。Ci-FoxQ在成年海鞘的几个内胚层器官中表达，如内柱、鳃囊和食管。在内柱中，Ci-FoxQ的表达模式与CiTTF-1相似，在7区和8区的甲状腺等效区域尤为显著。因此，这些Fox基因可能在海鞘内柱中发挥甲状腺等效功能。
