氚β辐射对神经细胞迁移相关因子表达的影响
Effects of Tritium β Irradiation on the Expression of Regulated Factors Associated with the Neural Cell Migration
摘要
Abstract
To explore the effects of HTO β irradiation on neural cell migration primary neural ceils were exposed to β rays from 0, 3.7 ×10^3, 3.7 ×10^4, 3.7 ×10^5 and 3.7 ×10^6 Bq/mL HTO for 24 h respectively., The migration distance of neural cells was measured with Leica AF 6000 live cell workstation, [Ca^2+] in neurons were detected using Fluo-3-AM fluorescent probe and flow cytometry, and the expressions of β-tubulin and NCAM proteins in neurons were assayed by Western blot. Results showed that: with the augmentation of HTO concentration and the increase of β irradiation doses, the distance of neural cells migration accordingly was reduced, intracellular free calcium ions in neurons were incremented, and the expressions of ~-tubulin and NCAM protein also were decreased. It suggested that HTO β irradiation may cause the alterations of the regulated factors associated with neural cell migration to prevent neural cell from migrating.关键词
