雌激素受体(ER)在正常乳房发育中起着至关重要的作用,并在最常见的乳腺癌亚型中表达。重要的是,它的表达对内分泌治疗的反应具有很高的预测性。目前雌激素受体阳性乳腺癌的内分泌治疗针对多个水平的雌激素受体功能。这些包括靶向雌激素水平,阻断雌激素在内质网的作用,以及降低内质网水平。然而,治疗的最终效果受到内在或获得性耐药性的限制。确定导致敏感性和耐药性的因素和途径仍然是改善乳腺癌治疗的一个挑战。随着对内质网协同作用、其协同调节因子以及其他细胞内信号级联的影响的更好理解,乳腺癌治疗的改进正在出现。
Estrogen receptor (ER) has a crucial role in normal breast development and is expressed in the most common breast cancer subtypes. Importantly, its expression is very highly predictive for response to endocrine therapy. Current endocrine therapies for ER-positive breast cancers target ER function at multiple levels. These include targeting the level of estrogen, blocking estrogen action at the ER, and decreasing ER levels. However, the ultimate effectiveness of therapy is limited by either intrinsic or acquired resistance. Identifying the factors and pathways responsible for sensitivity and resistance remains a challenge in improving the treatment of breast cancer. With a better understanding of coordinated action of ER, its coregulatory factors, and the influence of other intracellular signaling cascades, improvements in breast cancer therapy are emerging.
