Figure 1. Upregulation of TNKS1BP1 by ionizing radiation (IR) and its effect on the radiosensitivity of cells.
(A) Immunoblotting hybridization showing the increased expression of TNKS1BP1 protein in HeLa cells at given times after exposed to 4 Gy of γ-rays. (B) Immunoblotting hybridization showing the increased expression of TNKS1BP1 protein in MCF7, HepG2 and L02 cells at 4 h after different doses of γ-rays. (C) Increased TNKS1BP1 protein levels in both cytoplasm and nuclei in HeLa cells at 4 h after 4 Gy of γ-rays. (D) Quantitative real-time RT-PCR analysis showing the increased mRNA expression of TNKS1BP1 in HeLa cells at 2 h after 4 Gy of γ-rays. (E) Depletion of TNKS1BP1 expression in HeLa cells mediated by specific shRNA. (F) Depletion of TNKS1BP1 expression in HepG2 cells mediated by specific shRNA. (G) TNKS1BP1 depleted HeLa-shTNKS1BP1 cells became much more sensitive to IR as compared to the control HeLa-NC cells. (H) TNKS1BP1 depleted HepG2-shTNKS1BP1 cells became much more sensitive to IR as compared to the control HepG2-NC cells.
