| Research Abstract |
The present study aims at examing the radiation-sensitizing effect of G2 checkpoint abrogators against solid cancers and discovering the new anti-cancer agent which brings both benefits, enhancing the therapeutic efficacy and decreasing adverse effects of cancer radiotherapy. We examined the effects of various G2 checkpoint abrogators on G2 arrest induction and antiproliferative effect by X-ray irradiation against esophageal cancer cell line, TE5. Cell cycle analysis and trypan blue exclusion assay showed that UCN-01 abrogated G2 arrest and potentiated growth inhibition, respectively. Furthermore, Western blotting demonstrated that UCN-01 decreased the protein level of Chk1 kinase activated by X-ray irradiation.
