Does the mechanism for detoxification of hydrogen sulfide using deep-sea invertebrates exist also in shallow-water one?

有人认为，生活在热液喷口和冷泉的无脊椎动物通过在细胞中积累牛磺酸及其相关化合物来解毒硫化氢。在本研究中，我们尝试对牛磺酸转运体(TAUT)的mRNA进行定量，以确定这种硫化氢解毒机制是否普遍存在于浅水和深海无脊椎动物中。根据硫化物暴露实验的结果，深水和浅水贻贝都有可能使用相同的机制来解毒硫化氢。

It has been suggested that the invertebrates which inhabit at hydrothermal vents and cold seeps detoxify the hydrogen sulfide by accumulating taurine and its related compounds in their cells. In this study, we attempted quantification of taurine transporter(TAUT) mRNA to resolve whether this mechanism for detoxification of hydrogen sulfide universally exist among shallow-water and deep-sea invertebrates. On the basis of the result of sulfide exposure experiment, both deep-and shallow-water mussel showed the possibility of using the same mechanism for detoxification of hydrogen sulfide.
