ATF3 decreases the growth potential of HPV-positive cells. SiHa cells infected with shp53- or shLuc-expressing Lentiviruses were further infected with retroviruses expressing ATF3 or its vector pBabe for 2 days. The infected cells (200/well) were plated into 6-well plates, and cultured for 14 days. The colonies were stained with crystal violet (A) and counted (B).
