Further, with a semi-quantitative RT-PCR technique, the temporal expression of UuMAPKKK-like in U. unicinctus coelomic fluid cells was measured after stimulated by sulfide. The mRNA transcript of UuMAPKKK-like was low in the control and short time stressed (2 h, 6 h) groups, up-regulated gradually after 12h stimulation, and then reached its maximum level at 48h.
