Among the biological processes regulated by TRPV2 channel during metastatic progression, TRPV2 has been notably associated with proliferation, for instance in esophageal squamous cell carcinoma (Kudou et al, 2019), or with the progression toward a pro‐invasive phenotype in prostate and bladder cancers (Monet et al, 2009; Liu & Wang, 2013; Oulidi et al, 2013). The gene discussed is TRPV2; the disease is urinary bladder cancer.
