However, the inhibition of cell proliferation by miR‐34b/c‐5p overexpression was primarily consistent with the silencing of NK1R‐Tr, but not NK1R‐FL, in breast cancer and miR‐34b/c‐5p overexpression and NK1R‐Tr silencing both induced cell cycle G2/M arrest and apoptosis; furthermore, SP only partly rescued this effect. The gene discussed is TACR1; the disease is breast cancer.
