目的:探讨松针油对人乳腺癌细胞(MCF7)影响及可能损伤、凋亡及自噬的机制。方法:用不同浓度的松针油处理MCF7细胞24、48及72h后观察,用噻咗蓝(MTT)比色法测定MCF7细胞生长抑制;电镜下观察细胞凋亡的形态改变;流式细胞仪测定P53的表达及荧光法测定乳腺癌细胞自噬,流式细胞仪测定细胞凋亡率及银染法(TRAP-PCR)法测定端粒酶的活性变化。结果:不同浓度下的松针油对MCF的增值均有一定的抑制作用,能诱导MCF7细胞损伤、凋亡及自噬,且与作用时间及剂量明显相关。结论:松针油可通过抑制端粒酶的活性,促进P53、LC3-II表达来诱导MCF7细胞损伤、凋亡及自噬。

Objective:To study the influence MCF7 cells by pine needle oil and possible mechanism of trauma、apoptosis and autophagy.Methods Observed MCF7 cells with different concentrations of pine oil in 24、48 and 72h,detected growth inhibition rate of by thiazole blue colorimetry,cell morphologic changes were examined by electro-microscope,messuring expression of P53 by low cytometry,and autophagy of breast cancer cell with florescence,the rate of appptotic cells by flow cytometry and telomerase activity by TRAP assay.Result:Suppression MCF7 growth、trauma、apoptosis and autophagy by different concentrations of pine needle oil ,and correlated with active time and dosage obviously.Conclusion:Telomerase activity can be curbed by pine needle oil.MCF7 cell trauma ,apoptosis and autophagy can be accelerated by pine needle oil.
