中文摘要：

逐渐增多的研究表明,人们生活中经常接触到的一些化学物质是导致乳腺癌发生的危险因素;同时一些研究证实,Hedgehog（Hh）信号通路在乳腺癌患者组织中存在异常激活,参与乳腺癌的发生、调节乳腺癌干细胞生物学特性、促进肿瘤组织血管新生和乳腺癌细胞侵袭转移等生物学过程。本文通过对化学物质与Hh信号通路在乳腺癌发生、发展研究的最新进展进行综述,为进一步阐述乳腺癌发病机制和乳腺癌的预防及控制提供科学线索。

英文摘要：

The controversial results of several studies suggest that certain everyday-use chemicals may be linked to breast cancer. ln recent years, extensive researches have been carried out to under-stand breast carcinogenesis and the hedgehog（Hh） signaling pathway has emerged as a critical determi-nant of human breast cancer. Aberrant Hh signaling in adults results in carcinogenesis, angiogenesis, and metastasis. This review is focused on the Hh signaling pathway and chemicals in the regulation of breast cancer development and provide an updated survey of pre-clinical and clinical trials of novel strategies to target them.
