Figure 1. LPS and VSV promote Ets2 expression and nuclear translocation. (A, B) Ets2 mRNA expression in mouse primary peritoneal macrophages stimulated with 100 ng/ml LPS (A) or VSV at an MOI of 10 (B) for the indicated times, as detected by real-time PCR (n=3). (C) Immunoblot analysis and quantification of Ets2 expression in mouse primary peritoneal macrophages stimulated with 100 ng/ml LPS or VSV at an MOI of 10 for the indicated times. (D, E) Immunoblot analysis (D) and quantitative measurement (E) of nuclear/total lysate ratio of Ets2 of mouse primary peritoneal macrophages pretreated with SB203580, PD98059, or SP600125 (20 μM for 30 min) and then stimulated with or without 100 ng/ml LPS for 3 h. U6 was used as an internal reference for the nucleus. Data are shown as the mean ± s.d. Student’s t-test compared with the control group. *, P<0.05, and **, P<0.01.
