Fig. 2. Expression of EZI. (A) OSM-dependent LO cells were treated with OSM and harvested at 0, 0.5, 1 and 2 h after stimulation, and RNA was extracted for northern blotting. EZI mRNA was already present before stimulation and was induced slightly at 0.5 h after stimulation. (B) Expression of EZI in various adult tissues and cell lines was detected by northern blotting. (C) Expression of EZI in mouse embryonic tissues at E11.5 was examined by RT–PCR.
