“…The IC50 values were 479.15 and 351.6 µg/mL by NRU and MTT assay, respectively (Figure 2). According to the earlier studies, The NiO-NPs induced cellular death in human neuron, liver, lung, airway epithelial, and breast cells and rat kidney epithelial cells (Abudayyak et al 2017a;Ahamed, 2011;Ahamed et al, 2013;Ahmad et al, 2013;Chang et al, 2018;Di Bucchianico et al, 2018;Horie et al, 2011;Lanone et al, 2009;Lee et al, 2015;Mohamed et al, 2018;Siddiqui et al, 2012). We could indicate that Caco-2 cells were more vulnerable than other previously studied cells to cytotoxic damage induced by NiO-NPs.…”
