Figure 4. AREG up-regulates SPRY2 expression through EGFR in another human ovarian cancer cell line.

Figure 4

A. OVCAR5 cells were treated with 10 ng/mL AREG (AR) for different time periods, and SPRY2 protein levels were examined by Western blot. B. OVCAR5 cells were pre-treated with vehicle control (DMSO) or 10 μM AG1478 for 1 h and then treated with vehicle control (Ctrl) or 10 ng/mL AREG (AR) for 3 h. SPRY2 protein levels were examined by Western blot. C. OVCAR5 cells were transfected with 50 nM control siRNA (si-Ctrl) or EGFR siRNA (si-EGFR) for 48 h and then treated with vehicle control (Ctrl) or 10 ng/mL AREG (AR) for 3 h. The protein levels of SPRY2 and EGFR were examined by Western blot. The results are presented as the mean ± SEM of at least three independent experiments. Values without a common letter are significantly different (P < 0.05).
