摘要

背景:替诺福韦(Tenofovir, TFV)可引起部分患者肾小管功能障碍(KTD),但其机制尚不清楚。TFV转运蛋白的遗传变异是有牵连的;我们探讨了ABCC10是否转运TFV,以及ABCC10单核苷酸多态性(SNPs)是否与KTD相关。方法:在亲本和abcc10转染的HEK293细胞(HEK293- abcc10)、CD4(+)细胞和单核细胞来源的巨噬细胞(MDMs)中评估TFV的积累。底物特异性由头孢菌素(ABCC10抑制剂)和小干扰RNA (siRNA)研究证实。在人类免疫缺陷病毒阳性KTD患者(n = 19)或无KTD患者(对照组;N = 96)。使用Haploview进行SNP和单倍型分析。结果:HEK293- abcc10细胞系中TFV的积累明显低于亲本HEK293细胞(低35%;P = .02); this was reversed by cepharanthine. siRNA knockdown of ABCC10 resulted in increased accumulation of TFV in CD4(+) cells (18%; P = .04) and MDMs (25%; P = .04). Two ABCC10 SNPs (rs9349256: odds ratio [OR], 2.3; P = .02; rs2125739, OR, 2.0; P = .05) and their haplotype (OR, 2.1; P = .05) were significantly associated with KTD. rs9349256 was associated with urine phosphorus wasting (P = .02) and beta2 microglobulinuria (P = .04). CONCLUSIONS: TFV is a substrate for ABCC10, and genetic variability within the ABCC10 gene may influence TFV renal tubular transport and contribute to the development of KTD. These results need to be replicated in other cohorts.
