Cover: NGR-1_177-233 induces nuclear translocation of STAT3, NCI-H520 (A) and NCI-H441 (B) cells were grown on glass coverslips and growth-arrested for 48 h. The cells were stimulated with NRG-1_177-244 (10^-8 M) at 10 min, 30 min, and 1 h, and stained for STAT3, following an FITC-conjugated antibody (green). Nuclei were stained with DAPI.
