Erythrocebus patas (patas) monkeys were used to model antiretroviral (ARV) drug in human immunodeficiency virus type 1-infected pregnant women.
Pregnant patas dams were given human-equivalent doses of ARVs daily during 50% of gestation. Mesenchymal cells, cultured from bone marrow of patas offspring obtained at birth and at 1 and 3 years of age, were examined for genotoxicity, including centrosomal amplification, micronuclei, and micronuclei containing whole chromosomes.
Compared with controls, statistically significant increases (P < .05) in centrosomal amplification, micronuclei, and micronuclei containing whole chromosomes were found in mesenchymal cells from most groups of offspring at the 3 time points.
Transplacental nucleoside reverse-transcriptase inhibitor exposures induced fetal genotoxicity that was persistent for 3 years.
食蟹猴(patas)被用于模拟人类免疫缺陷病毒 1 型感染孕妇的抗逆转录病毒(ARV)药物。
在妊娠的 50%期间,给予妊娠食蟹猴每日给予相当于人类的 ARV 剂量。从出生和 1 岁和 3 岁时获得的食蟹猴后代的骨髓中培养间充质细胞,检查其遗传毒性,包括中心体扩增、微核和含有整条染色体的微核。
与对照组相比,在 3 个时间点,来自大多数后代组的间充质细胞中,中心体扩增、微核和含有整条染色体的微核均有统计学意义的增加(P <.05)。
