Galectin-1 inhibits radiation-induced cell death. Clonogenic survival curves were compared between (a) galectin-1 knockdown and scrambled RNA in HeLa cells 48 h after transfection (b) galectin-1 cDNA and GFP vectors in HeLa cells (c) galectin-1 knockdown and scrambled RNA in C33A cells 48 h after transfection (d) galectin-1 cDNA and GFP vectors in C33A cells. Cells were irradiated and clonogenic assay performed 12 to 14 days following irradiation. Clonogenic assays were performed during three independent experiments at each paired condition (with and without galectin-1 modulation). The error bar represents the standard error of mean: ^*P<0.05, ^**P<0.01, and ^***P<0.001
