摘要: 目的:探讨人生长激素释放激素受体剪接变异体1型(GHRHR SV1)对肝癌细胞系HepG2增殖的影响,阐明GHRHR SV1对人肿瘤细胞的促增殖作用。方法:将GHRHR SV1真核表达载体导入HepG2细胞建立HepG2-SV1细胞系。设计对照组(野生型HepG2)、空载质粒组(HepG2-pCDNA3.0细胞系)和干扰组(HepG2-SV1细胞系)。采用PCR和Westernblotting法鉴定HepG2-SV1细胞系,CCK-8法检测各组细胞的增殖率,克隆形成实验检测各组细胞的单克隆形成率,细胞划痕实验检测细胞的迁移率。结果:PCR与Westernblotting法检测,构建的HepG2-SV1细胞系能稳定表达GHRHR SV1;CCK-8法检测,干扰组HepG2-SV1细胞系的增殖率高于空载质粒组HepG2-pcDNA3.0细胞系(P<0.05);克隆形成实验,干扰组HepG2-SV1细胞系的单克隆形成率约为空载质粒组HepG2-pcDNA3.0细胞系的3.5倍(P<0.05);细胞划痕实验,所构建的干扰组HepG2-SV1细胞系的迁移率高于空载质粒组HepG2-pcDNA3.0细胞系(P<0.05)。结论:GHRHR SV1能促进HepG2细胞的增殖。

Abstract: Objective: To investigate the effect of human growth hormone releasing hormone receptor splice variant type 1 (GHRHR SV1) on the proliferation of human liver cancer HepG2 cells, and to clarify the proliferation effect of GHRHR SV1 on the human cancer cells. Methods: The GHRHR SV1 plasmids were transfected into the human HepG2 cells to construct the HepG2-SV1 cell line. HepG2 group(HepG2 cells),HepG2-empty group(HepG2-pcDNA3.0 cell line) and HepG2-SV1 group(HepG2-SV1 cells) were set up. PCR and Western blotting methods were used to identify the HepG2-SV1 cell line;CCK-8 method was used to detect prolifernation rate of cells;colony formation assay was used to detect the colony formation rate of cells;cell wound healing assay was used to evaluate the migration rate of cells. Results: The PCR and Western blotting results showed the HepG2-SV1 cell line expressed GHRHR SV1 steadily.The CCK-8 results showed that the proliferation rate of the HepG2-SV1 cells in HepG2-SV1 group was higher than that of the HepG2-pcDNA3.0 cells in HepG2-empty group(P<0.05).The colony formation assay results showed that the colony formation rate of HepG2-SV1 cells in HepG2-SV1 group was 3.5 times higher than that of the HepG2-pcDNA3.0 cells in HepG2-empty group(P<0.05).The cell wound scratch assay results showed that the migration rate of the HepG2-SV1 cells in HepG2-SV1 group was higher than that of the HepG2-pcDNA3.0 cells in HepG2-empty group(P<0.05). Conclusion: GHRHR SV1 could increase the proliferation of HepG2 cells.

Key words: HepG2 cells, cell proliferation, colony formation rate, migration rate, human growth hormone releasing hormone receptor splice variant type 1
