白细胞介素-35对肝癌细胞株HepG2增殖和迁移能力的影响

摘要

Objective To investigate effects of interleukin-35 (IL-35) on proliferation,invasion and migration of a HepG2 cell line in vitro.Methods Enzyme-linked immunosorbent assay (ELISA) was used to determine peripheral blood expression levels of IL-35 in hepatocellular carcinoma patients and in normal healthy subjects.The effects of exogenous IL-35 on cell proliferation activity of HepG2 in vitro were measured using CCK-8 assay.The transwell invasion and scratch test were used to study the invasive and migration abilities.Results The content of IL-35 protein in hepatocellular carcinoma patients (HCC) was significantly higher than in healthy individuals [(118.45 ±28.66) ng/L vs (39.56 ± 11.15) ng/L,P ＜0.05].Exogenous IL-35 significantly promoted proliferation,invasion and migration abilities of HepG2 cells in vitro (P ＜ 0.05).Conclusions The level of IL-35 was elevated significantly in hepatocellular carcinoma patients.IL-35 had biological characteristics of promoting HCC cell proliferation,invasion and migration.%目的 探讨白细胞介素-35(IL-35)对肝癌细胞株HepG2增殖活性、迁移和侵袭能力的影响.方法 采用酶联免疫吸附法(ELISA)法检测肝细胞癌(HCC)患者和正常体检者外周血IL-35含量;CCK-8法检测外源性IL-35在体外对肝癌细胞增殖活性的影响;Transwell侵袭和划痕实验检测外源性IL-35对肝癌细胞侵袭和迁移能力的影响.结果 IL-35在HCC患者外周血的IL-35含量[(118.45±28.66) ng/L]显著高于健康体检者外周血[(39.56 ± 11.15) ng/L,P＜0.05];加入外源性人重组IL-35可以显著促进HepG2细胞的增殖活性、侵袭和迁移能力(P＜0.05).结论 IL-35具有促进肝癌细胞增殖、迁移和侵袭的生物学特性.
