A peer group of researchers (Ekinci et al., 2018; Samarghandian et al., 2019) in another study evaluated the anticancer role of thymoquinone against human lung cancer cell line (A549 cells) via lowering the viability, inducing apoptotic cell death, enhancing the Bax/Bcl‐2 ratio, upregulating the p53 expression, and activating the caspase‐3 and caspase‐9, respectively (Ekinci et al., 2018; Samarghandian et al., 2019). The gene discussed is TP53; the disease is lung cancer.
