Thymoquinone effects on cancer stem cells, Bashmail et al. (2020), showed that thymoquinone alone or in combination with paclitaxel decreased CD44+/CD24− stem cell clones in both MCF-7 and T47D cells (breast cancer) through the inhibition of EMT and the down-regulation of TWIST-1 gene [280]. This evidence concerns the gene CD24 and breast carcinoma.
