RELA and lung carcinoma: Our present results have demonstrated that TBrC and T significantly inhibits both the growth of human lung cancer A549 and H460 cell lines as well as the TNFα-induced nuclear transcriptional activation of NF-κB p65 in A549 cells without affecting cell viability of the normal human lung cells (Figure 5), suggesting that TBrC and T of tea could display more benefits in vivo than in vitro against SARS-CoV-2 damage to human health.
