Abstract

OBJECTIVES

Although thyroid cancer occurs much more frequently in females, the role of sex hormones in thyroid carcinogenesis is unknown. In this study, it has been investigated how 17beta-oestradiol (E2) influenced proliferation and growth of thyroid cancer cells.

MATERIALS AND METHODS

Cell proliferation and its related molecules were examined in thyroid papillary carcinoma cells (KAT5), follicular thyroid carcinoma cells (FRO) and anaplastic carcinoma cells (ARO). Levels of oestrogen receptor (ER) alpha and beta were regulated by their agonists (PPT and DPN), antagonists and siRNA.

RESULTS

E2 promoted cell proliferation. Such an effect was positively related to ERalpha but negatively to ERbeta; PPT enhanced cell proliferation while DPN inhibited it. PPT increased Bcl-2 expression while DPN decreased it. DPN also elevated Bax expression. PPT elevated the level of phosphorylated extracellular signal-regulated kinase 1/2 (pERK1/2), suggesting a positive role of ERK1/2 in E2-induced cell proliferation. Knockdown of ERalpha significantly attenuated E2-mediated Bcl-2 and pERK1/2 expression. In contrast, knockdown of ERbeta markedly enhanced them.

CONCLUSIONS

Oestrogen stimulates proliferation of thyroid cancer cells, associated with increase in Bcl-2 and decrease in Bax levels in an ERK1/2-related pathway. Imbalance between ERalpha and ERbeta may contribute to thyroid carcinogenesis.

摘要

目的

尽管甲状腺癌在女性中更为常见,但性激素在甲状腺癌发生中的作用尚不清楚。在本研究中,已对17β-雌二醇(E2)如何影响甲状腺癌细胞的增殖和生长进行了研究。

材料与方法

在甲状腺乳头状癌细胞(KAT5)、滤泡状甲状腺癌细胞(FRO)和未分化癌细胞(ARO)中检测细胞增殖及其相关分子。雌激素受体(ER)α和β的水平通过其激动剂(PPT和DPN)、拮抗剂和小干扰RNA进行调节。

结果

E2促进细胞增殖。这种作用与ERα呈正相关,与ERβ呈负相关;PPT增强细胞增殖,而DPN抑制细胞增殖。PPT增加Bcl-2表达,而DPN降低Bcl-2表达。DPN还升高Bax表达。PPT升高磷酸化细胞外信号调节激酶1/2(pERK1/2)的水平,提示ERK1/2在E2诱导的细胞增殖中起积极作用。敲低ERα显著减弱E2介导的Bcl-2和pERK1/2表达。相反,敲低ERβ则显著增强它们的表达。

结论

雌激素刺激甲状腺癌细胞增殖,与ERK1/2相关途径中Bcl-2增加和Bax水平降低有关。ERα和ERβ之间的失衡可能导致甲状腺癌的发生。
