Alteration of the ERα/ERβ balance is a critical step in breast cancer development and progression, and selective restoration of the activity of estrogen receptors has been proposed as one of the major therapeutic approaches for breast cancer. In this issue of JCI, Cheng et al. show that, by differentially modulating the stability of ERα and ERβ, PES1 increases the ERα/ERβ ratio and triggers breast tumor growth. These findings highlight PES1 as a potential target for the treatment of breast cancer.
雌激素受体(ER)α/β 平衡的改变是乳腺癌发生和发展的关键步骤,选择性恢复雌激素受体的活性已被提议作为乳腺癌的主要治疗方法之一。在本期 JCI 中,Cheng 等人表明,通过差异调节 ERα 和 ERβ 的稳定性,PES1 增加了 ERα/ERβ 比值并引发乳腺肿瘤生长。这些发现强调了 PES1 作为治疗乳腺癌的潜在靶点。
