槲皮素以及槲皮素联合顺铂对子宫颈癌细胞黏附、迁移和侵袭的影响

摘要

Objective To explore the effects of quercetin and quercetin in combination with cisplatin on adhesion, migration and invasion of HeLa cells. Methods Adhesion, migration and invasion of HeLa cells treated with quercetin and quercetin in combination with cisplatin were measured by adhesion assay, wound healing assay, and transwell chamber method respectively. Results The results showed that quercetin and quercetin in combination with cisplatin could inhibit adhesion, migration and invasion of HeLa cells. The adhesive ratio, migration rate and the invasiveness were negatively proportional to concentration of quercetin and quercetin in combination with cisplatin. With increasing concentration of quercetin from 20 to 80 μmol/L, the adhesive ratio decreased from ( 82. 2±1. 5 ) % to ( 48. 4±1. 1 ) % ; the migration rote decreased from (7.26±0. 20) μm/h to (3.78±0. 64) μm/h; the invasiveness decreased from ( 124. 3± 1. 5) piece to (90. 7±2. 1 ) piece(P <0. 05). In quercetin and quereetin in combination with 10 μmol/L cisplatin treatment group, with quercetin concentration increasing from 20 to 80 μmol/L, the adhesive ratio decreased from (42. 6±1. 2) % to ( 27. 5±1. 7 ) %, the migration rate decreased from ( 2. 20±0. 33) μm/h to (0.72±0. 19) μm/h and the invasiveness decreased from (78.7±2.5) piece to (44.0±4.0) piece (P < 0. 05 ). Compared with the quercetin groups, querectin in combination with cisplatin groups had significantly higher inhibitory effects ( P < 0. 05 ). Conclusions Quercetin and quercetin in combination with cisplatin can inhibit adhesion and migration and invasion of HeLa cells. Quercetin can enhance the inhibitory effect of cisplatin on HeLa cell adhesion, migration and invasion.%目的 探讨槲皮素以及槲皮素联合顺铂对宫颈癌细胞黏附、迁移和侵袭的影响.方法 以不同浓度(20、40、80 μmol/L)槲皮素以及槲皮素联合顺铂(10 μmol/L)处理宫颈癌细胞株HeLa细胞,采用细胞黏附实验、划痕实验和穿膜小室侵袭实验分别检测处理前后HeLa细胞黏附率、迁移速度以及侵袭力(以穿膜细胞数表示)的变化.结果 不同浓度的槲皮素处理后,随着槲皮素浓度从20 μmol/L增加至80 μmol/L,细胞黏附率由(82.2±1.5)%降至(48.4±1.1)%;细胞迁移速度由(7.26±0.20)μm/h降至(3.78±0.64)μm/h;穿膜细胞数由(124.3±1.5)个降至(90.7±2.1)个,分别比较,差异均有统计学意义(P<0.05).顺铂联合槲皮素处理后,随着槲皮素浓度从20 μmol/L增加至80 μmol/L,细胞黏附率由(42.6±1.2)%降至(27.5±1.7)%;细胞迁移速度由(2.20±0.33) μm/h降至(0.72±0.19) μm/h;穿膜细胞数由(78.7±2.5)个降至(44.0±4.0)个,分别比较,差异均有统计学意义(P<0.05).槲皮素联合顺铂处理后对HeLa细胞黏附、迁移和侵袭的抑制作用明显强于单纯槲皮素处理者(P<0.05).结论 槲皮素以及槲皮素联合顺铂能抑制HeLa细胞黏附、迁移及侵袭,槲皮素能增强顺铂对HeLa细胞黏附、迁移及侵袭的抑制作用.
