目的研究應用潘生丁(DP)阻斷平衡型核苷轉(zhuǎn)運載體(hENTs)后，5-氟尿嘧啶(5-FU)對胰腺癌細胞株Panc-1凋亡及細胞周期的影響。方法將Panc-1細胞分為hENTs未阻斷組和hENTs阻斷組，hENTs阻斷組再根據(jù)DP濃度分為5 μmol/L DP組和10 μmol/L DP組。各組細胞分別在含有1.5×106 ng/L 5-FU或不含5-FU的培養(yǎng)液中培養(yǎng)24 h后，流式細胞儀檢測細胞的凋亡率和細胞周期改變。結(jié)果①各組細胞凋亡檢測結(jié)果： 在含有1.5×106 ng/L 5-FU培養(yǎng)液中培養(yǎng)24 h后，5 μmol/L 及10 μmol/L DP組的細胞凋亡率明顯高于未阻斷組(P lt;0.05)，10 μmol/L DP組又明顯高于5 μmol/L DP組(P lt;0.05); 在不含5-FU的培養(yǎng)液中培養(yǎng)24 h后，各組之間細胞凋亡率比較差異無統(tǒng)計學意義(P gt;0.05)。②各組細胞周期檢測結(jié)果： 在含有1.5×106 ng/L 5-FU培養(yǎng)液中培養(yǎng)24 h后，未阻斷組細胞進入合成期(S期)的比例減少，停滯在合成前期(G1期),5 μmol/L DP組及10 μmol/L DP組的細胞進入合成期(S期)的比例較未阻斷組進一步減少(P lt;0.05)，且隨著DP濃度的增加，細胞進入合成期(S期)的比例減少得更多(P lt;0.05)，5 μmol/L DP組和10 μmol/L DP組進入合成期（S期）的比例分別是未阻斷組的87.09%和74.06%。5-FU對細胞合成后期(G2期)的影響較小，除5 μmol/L DP組較未阻斷組G2期細胞數(shù)量增加有統(tǒng)計學意義(P lt;0.05)外，其余各組之間差異均無統(tǒng)計學意義(P gt;0.05); 在不含5-FU的培養(yǎng)液中培養(yǎng)24 h后，各組細胞周期中各期無明顯改變，各組之間比較差異均無統(tǒng)計學意義(P gt;0.05)。結(jié)論在胰腺癌細胞株Panc-1中，DP阻斷細胞膜上hENTs后，能顯著增強5-FU對胰腺癌細胞促凋亡作用及抑制胰腺癌細胞分裂增殖的作用，這種增強作用可能與阻斷hENTs后細胞內(nèi)5-FU濃度提高有關，而與DP本身作用無關。
