硼替佐米单药及联合5-氟尿嘧啶对绒癌细胞增殖与凋亡的影响

硼替佐米单药及联合5-氟尿嘧啶对绒癌细胞增殖与凋亡的影响摘要：目的：探究硼替佐米单药及联合5-氟尿嘧啶（5-FU）对绒癌细胞增殖与凋亡的影响。方法：采用CCK-8法、流式细胞仪和Westernblot法评估硼替佐米单药及联合5-FU对绒癌细胞株COLO205的抑制作用和促进凋亡作用。结果：硼替佐米及5-FU均能够抑制COLO205细胞的增殖且呈剂量及时间依赖性关系，且联合应用可增加细胞凋亡率。Westernblot结果显示，硼替佐米及5-FU单药或联合应用均能够上调Bax、下调Bcl-2，促进细胞凋亡，而联合应用的效果更为明显。结论：硼替佐米及5-FU单药或联合应用均具有抗绒癌作用且可促进细胞凋亡，其中联合应用的疗效最佳。
