Indeed, pharmacological inhibition or silencing of KCa3.1 modulated oxidative phosphorylation (Kovalenko et al. 2016) and a mitochondriotropic version of the small molecule inhibitor TRAM‐34 (mitoTRAM‐34) efficiently killed tumor cells by inducing apoptosis (Bachmann et al. 2022). This evidence concerns the gene KCNN4 and neoplasm.
