许多外源性物质通过改变靶基因的转录来调节细胞功能。使用基于基因转录水平的敏感和特异性生物标志物可能有助于澄清与人类暴露于化学品环境浓度相关的低剂量区域的剂量反应曲线形状。我们已经量化的基因转录诱导的2,3,7,8-四氯二苯并-p-二恶英在动物模型和人类使用的北方分析和PCR为基础的方法。此外,我们描述了一种快速和敏感的体外测定,我们已经用来筛选化学品和生物样品的能力,改变基因转录。虽然我们研究中的一些终点(如细胞色素P-450 1A 1)是暴露和剂量的预测指标,但其他基因反应(如生长因子)更为复杂,代表了关键事件、进展或对病理学改变的适应。总之,有毒物质诱导的基因转录的测量将有助于生物标志物在解决人类健康和环境引起的疾病的问题的有用性。
Numerous xenobiotics regulate cellular functions by altering transcription of target genes. Use of sensitive and specific biomarkers based on gene transcript levels may help clarify the shape of the dose-response curve in the low-dose region associated with human exposures to environmental concentrations of chemicals. We have quantified gene transcription induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin in both animal models and humans with the use of Northern analysis and PCR-based methods. In addition, we describe a rapid and sensitive in vitro assay that we have used to screen chemicals and biological samples for their ability to alter gene transcription. Whereas some of the endpoints in our studies such as cytochrome P-450 1A1 are predictive indicators of exposure and dose, other gene responses such as growth factors are more complex and represent a critical event, progression, or adaptation to a pathological alteration. In conclusion, measurement of toxicant-induced gene transcription will contribute to the usefulness of biomarkers in addressing issues of human health and environmentally induced disease.
