| 目的：研究900 MHz手机辐射对人视网膜色素上皮细胞(RPE)增殖活性及转化生长因子β2(TGF-β2)表达的影响。 方法：RPE细胞体外培养和传代后分组。给予900 MHz手机电磁辐射者为辐射组,未给予辐射者为对照组。CCK8法检测RPE细胞的增殖活性。Real-Time PCR法检测TGF-β2 mRNA的表达。ELISA法检测RPE细胞培养上清液中TGF-β2的蛋白含量。结果：与对照组相比,辐射组RPE细胞的增殖活性降低,TGF-β2 mRNA表达增加,RPE细胞培养上清中TGF-β2含量上调,且差异具有统计学意义(P<0.05)。结论： 900 MHz的手机辐射在一定程度上影响了体外培养的RPE细胞的增殖活性及TGF-β2的表达与分泌,手机辐射有可能与受TGF-β2调控的眼部疾病相关。 |

| Objective: To investigate the effect of 900 MHz mobile phone radiation on proliferative activity and expression of transforming growth factor-β2(TGF-β2) in human retinal pigment epithelium (RPE). Methods: RPE cells were cultured and passaged in vitro and divided into two groups. The radiation group was given exposure with a 900 MHz mobile phone in call and the control group were not given any exposure. Proliferation of RPE cells was detected by the cell-counting kit-8 (CCK8) assay. The expression of TGF-β2 mRNA and protein secretion were measured by Real-Time quantitative polymerase chain reaction (Real-Time PCR) and Enzyme-linked immunosorbent assay (ELISA), respectively. Results：The viability of RPE cells in radiation group was inhibited compared to the control group. The level of TGF-β2 mRNA and secretion was up-regulated under the exposure in contrast with the control group. The differences were statistically significant(P<0.05). Conclusions：900 MHz mobile phone radiation altered the proliferative activity and the expression of TGF-β2 in RPE cells in some experimental condition and might have an underlying association with some eye diseases related with TGF-β2. |
