人群中肝脏CYP 3A 4水平存在巨大差异,这被认为导致个体对药物的反应不同。CYP 3A 4的转录受转录因子如CYP 3A 4 X受体(PXR)的调控。先前报道miRNA hsa-miR-148 a影响HepG 2细胞和日本人群中PXR的表达。在这项研究中,我们在中国汉族人群(N = 24)中进行了类似的相关性研究。  未发现hsa-miR-148 a与PXR表达或CYP 3A 4表达显著相关。我们的研究结果表明,hsa-miR-148 a在中国汉族人群肝脏PXR或CYP 3A 4表达的调控中不起主要作用。
There is a huge variability of hepatic CYP3A4 level in human populations, which was believed to contribute to different responses to drugs among individuals. Transcription of CYP3A4 was regulated by transcription factors such as pregnane X receptor (PXR). MiRNA hsa-miR-148a was previously reported to influence PXR expression in HepG2 cells and in Japanese populations. In this study, we conducted a similar correlation study in Chinese Han population (N = 24). No significant correlation of hsa-miR-148a was found with PXR expression or CYP3A4 expression. Our results suggest that hsa-miR-148a does not play a major role in the regulation of PXR or CYP3A4 expression in human livers from Chinese Han population.
