Testicular histopathological lesions like detachment, atrophy and vacuolization of germ cells were observed. The results showed that increased dosage of ZnO NPs correspondingly up-regulated the IRE1α, XBP1s, BIP, and CHOP (P<0.05) which are genes related to ER stress. These observations indicated that ZnO NPs had adverse effects on the male reproductive system in a dose-dependent manner possibly through ER stress. The expression of caspase-3 was significantly increased in all the treated groups (P<0.001), which reflected the possible activation of apoptosis. Additionally, there was significant down-regulation of the gene StAR (P<0.05), a key player in testosterone synthesis. When an ER-stress inhibitor salubrinal was administered to the 450 mg/kg ZnO NPs treatment group, the damages to the seminiferous tube and vacuolization of Sertoli and Leydig cells were not observed. Furthermore, the testosterone levels in the serum were similar to the control group after the subsequent salubrinal treatment.Conclusion: It may be inferred that the ZnO NP’s reproductive toxicity in male mice occurred via apoptosis and ER-stress signaling pathway.Keywords: zinc oxide nanoparticles, male reproductive toxicity, endoplasmic reticulum stressTang YChen BHong WChen LYao LZhao YAguilar ZPXu HDove Medical Pressarticlezinc oxide nanoparticlesmale reproductive toxicityendoplasmic reticulum stressMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 14, Pp 9563-9576 (2019) |
