PCNA and leiomyoma: In previous works, we demonstrated the anti‐leiomyoma effects of simvastatin using in vitro and in vivo models, including inhibiting proliferation in mature leiomyoma cells by suppressing PCNA expressions,21 inducing calcium‐dependent apoptosis,22 reducing ECM deposition,23 and modulating oestrogen39 and mechanotransduction signalling.26
