Fig. 2From: Knockdown of ribosomal protein S15A induces human glioblastoma cell apoptosisLentivirus-mediated knockdown of RPS15A suppresses cell viability and the colony formation ability of U251 cells. a Growth curve of U251 cells with three treatments (shCon, shRPS15A-1, and shRPS15A-2) determined by MTT assay. b Representative images of colonies formed in U251 cells with three treatments (shCon, shRPS15A-1, and shRPS15A-2) measured by the colony formation assay. c Statistical analysis of colony formation ability as shown. The experiments was performed in triplicate and repeated three times. **p < 0.01, ***p < 0.001Back to article page
