摘要:
目的 研究褪黑素对大鼠乳腺癌组织中雌激素受体表达的影响,分析褪黑素在乳腺癌发生发展中的作用。方法 选用 2月龄清洁级雌性SD大鼠90只,接种大鼠乳腺癌细胞,随机分为注射生理盐水对照组、7.5 mg/(kg·d)注射褪黑素组、15 mg/ (kg·d)注射褪黑素组,10 d后乳腺癌大鼠荷瘤模型建立成功并取乳腺癌组织,采用免疫组化法检测乳腺癌中雌激素受体的表 达情况。结果 注射褪黑素组的大鼠乳腺癌组织雌激素受体表达指数低于注射生理盐水对照组,随着注射褪黑素剂量上升, 雌激素受体表达指数进一步下降,差异具有统计学意义(P<0.05)。结论 褪黑素能抑制乳腺癌组织中雌激素受体的表达,可 能是褪黑素拮抗乳腺癌发生发展的途径之一。
Abstract:
Objective To study the effect of melatonin on the expression of estrogen receptor in rats breast cancer, and to analyze the role of melatonin in the development of breast cancer. Methods Ninety female rats of clean grade SD in age 2 months were selected, and the breast cancer cells were inoculated in the rats. The rats were randomly divided to control group injected with saline, group injected with melatonin at a dose of 7.5 mg/(kg·d), group injected with melatonin at a dose of 15 mg/(kg·d). The breast cancer tumor bearing models of rats were established on the 10th day after inoculating, and the tissues of breast cancer were taken out. The expression of estrogen receptor in breast cancer was detected by immunohistochemistry method. Results The estrogen receptor expression index of rats breast cancer tissues in the group injected with melatonin was lower than that in the control group injected with saline, the estrogen receptor expression index further decreased with the increase of the dose of melatonin. Above differences were statistically significant. Conclusion Melatonin can inhibit the expression of estrogen receptor in breast cancer tissues, which may be one of the ways to prevent the development of breast cancer.
