In Lea V Weber’s (Weber et al., 2016) experiments, they also demonstrated a significant reduction in the growth rate of MCF-7 breast cancer cells after stimulation with the TRPV1 agonist capsaicin, a finding consistent with the results of Vercelli et al. Zheng et al. (2016) further showed that capsaicin was able to potentiate the antitumour effect of pirorubicin. This evidence concerns the gene TRPV1 and breast carcinoma.
