In this issue of Developmental Cell, Infante et al. (2015) compare regulatory DNA sequences in mice, lizards, and limbless snakes to reveal widespread sharing of enhancer activity in developing limbs and genitalia. Genetic deletion of a limb-genital enhancer demonstrates that common regulatory elements affect development of both appendages.
在本期《发育细胞》中，Infante 等人（2015）比较了小鼠、蜥蜴和无肢蛇的调控 DNA 序列，揭示了在发育中的四肢和生殖器中广泛存在的增强子活性共享。肢体-生殖器增强子的遗传缺失表明，常见的调控元件影响了两种附肢的发育。
