Solanesol alleviates metal oxide nanoparticles generated toxicity in human placental BeWo cells

Recent research has provided evidence that metal oxide nanoparticles (NPs) have the potential to traverse the placental barrier, potentially endangering the health of both pregnant individuals and the developing fetus. The function of oxidative stress is of utmost importance in the pathophysiology of poor pregnancy outcomes. The therapeutic potential of solanesol in mitigating pregnancy complications is attributed to its robust antioxidant activity. The objective of this work was to inspect the preventative effects of solanesol on the detrimental effects generated by CuO and NiO NPs in human placental cells (BeWo). It was noticed that the exposure of BeWo cells to solanesol at concentrations ranging from 1 to 100 mu g/ml for a duration of 24 h did not result in any harmful effects. However, the presence of CuO and NiO NPs led to a dose-dependent decrease in cell viability when exposed to dosages of 5 to 200 mu g/ml for 24 h. It is noteworthy that solanesol significantly reduced the cyto-toxicity that CuO and NiO NPs generated in BeWo cells. The data on apoptosis also demonstrated that CuO and NiO NPs have effect on the expression of the apoptotic gene caspase-3 and the decline of mitochondrial mem-brane potential. However, this effect was effectively reversed when solanesol was administered in combination with NPs. The findings of the mechanistic investigation indicate that the CuO and NiO NPs induced oxidative stress was notably negated when solanesol was concurrently treated. This paper presents novel findings indi-cating that the toxicity generated by CuO and NiO NPs in human placental cells was significantly alleviated by solanesol. Further work is necessary to explore the pharmacological potential of solanesol against nanoparticle-generated pregnancy problems.

Automated summary

Recent research has found that metal oxide nanoparticles may pose a threat to the health of pregnant individuals and developing fetuses. This study aimed to investigate the preventative effects of solanesol on the harmful effects caused by copper oxide (CuO) and nickel oxide (NiO) nanoparticles in human placental cells. The results showed that solanesol significantly alleviated the cytotoxicity and apoptosis induced by the nanoparticles. Further research is needed to explore the pharmacological potential of solanesol against nanoparticle-generated pregnancy problems.
