(A) Clonogenic assay, comparing the radiosensitivity of Hek293 cell line stabile transfected with an empty vector or with a plasmid overexpressing phosphatase and tensin homologue deleted on chromosome 10 (PTEN). (B) Western blot analysis for PTEN, RAD51 and β-actin. Notice that overexpression of PTEN is associated with overexpression of Rad51 in the stabile transfected PTEN cell line.
