Oestrogen receptor (ER)-positive breast cancer is one of the common forms of breast cancer affecting women worldwide. ER-positive breast cancer patients are subjected to anti-oestrogen therapy such as selective oestrogen receptor modulator (SERM) and aromatase inhibitors (AIs). Recently, the emergence of resistance to anti-oestrogen treatment is under intensive focus. The different mechanisms postulated to explain the occurrence of resistance in ER-positive breast cancer treatment include the loss of ER function and the crosstalk between signalling pathways in cancer cells. Recent literature highlighted that the cholesterol biosynthesis pathway acts as a novel mechanism underlying resistance to oestrogen deprivation. The present study aimed to highlight the role of cholesterol biosynthesis in anti-oestrogen treatment resistance, putatively suggesting an alternative plant-based treatment using andrographolide from . The hypolipidaemic effect of andrographolide can be utilised to prevent the resistance in the treatment of ER-positive breast cancer contributed by cholesterol biosynthesis.
雌激素受体(ER)阳性乳腺癌是影响全球女性的常见乳腺癌形式之一。ER阳性乳腺癌患者会接受抗雌激素治疗,如选择性雌激素受体调节剂(SERM)和芳香化酶抑制剂(AI)。最近,抗雌激素治疗耐药性的出现受到了密切关注。为解释ER阳性乳腺癌治疗中耐药性产生而提出的不同机制包括ER功能丧失以及癌细胞信号通路之间的相互作用。最近的文献强调,胆固醇生物合成途径是雌激素剥夺耐药性的一种新机制。本研究旨在突出胆固醇生物合成在抗雌激素治疗耐药性中的作用,推测性地提出使用穿心莲内酯进行基于植物的替代治疗。穿心莲内酯的降血脂作用可用于预防胆固醇生物合成导致的ER阳性乳腺癌治疗中的耐药性。
