Keywords | 食道癌 / 食道癌細胞株 / siRNA / Rad51 / CDK4/6阻害薬 / Palbociclib / DNA2本鎖切断 / 相同組換え修復 / 化学放射線療法感受性 / 食道扁平上皮癌 / 化学放射線療法 / 切除不能進行・再発食道癌 / 白金製剤 / DNA損傷 / E2F1 |
Outline of Research at the Start |
食道扁平上皮癌の化学放射線療法感受性に関与する相互組換え修復の主要因子であるRad51発現を調節するE2F1/Rb-CDK4/6/Cyclin D1経路に着目し、CDK4/6阻害薬による化学放射線療法の感受性の改善効果を検討する。
|
Outline of Final Research Achievements |
1) Inhibition of Rad51 expression by siRNA in esophageal cancer cell lines improved sensitivity to cisplatin.2) Suppression of Rad51 expression by siRNA in esophageal cancer cell lines improved sensitivity to radiation.3) We focused on E2F1 as a factor that binds to the promoter region of Rad51, and treatment of the cell lines with Palbociclib, a CDK4/6 inhibitor, reduced Rad51 protein expression.(4) Treatment with Palbociclib in Rad51-high expressing cell lines increased sensitivity to cisplatin.

Academic Significance and Societal Importance of the Research Achievements |
食道扁平上皮癌の化学放射線療法感受性に関与する相互組換え修復の主要因子であるRad51発現を調節するE2F1/Rb-CDK4/6/Cyclin D1経路に着目し、CDK4/6阻害薬による化学放射線療法の感受性の改善効果を検討する。同経路を標的とした相互組換え修復の抑制による化学放射線療法感受性の向上に関する研究は存在しない。本研究により難治性癌である食道扁平上皮癌に対する化学放射線療法の奏効割合が大きく改善する可能性があり、本研究の意義は大きいと考える。
