英文摘要

Context: The incidence of papillary thyroid cancer (PTC) shows a predominance in females, with a male: female ratio of 1: 3, and none of the known risk factors are associated with gender difference. Increasing evidence indicates a role of estrogen in thyroid tumorigenesis, but the mechanism involved remains largely unknown.

Objective: This study aimed to assess the contribution of autophagy to estrogen receptor alpha (ER alpha)-mediated growth of PTC.

Design: The expression of ER alpha in thyroid tissue of patients with PTC tissues was analyzed. Cell viability, proliferation, and apoptosis were evaluated after chemical and genetic inhibition of autophagy. Autophagy in PTC cell lines BCPAP and BCPAP-ER alpha was assessed.

Results: ER alpha expression was increased in PTC tissues compared with the adjacent nontumor tissues. Estrogen induced autophagy in an ER alpha-dependent manner. Autophagy induced by estrogen/ER alpha is associated with generation of reactive oxygen species, activation of ERK1/2, and the survival/growth of PTC cells. Chemical and genetic inhibition of autophagy dramatically decreased tumor cell survival and promoted apoptosis, confirming the positive role of autophagy in the growth of PTC.

Conclusions: ER alpha contributes to the growth of PTC by enhancing an important prosurvival catabolic process, autophagy, in PTC cells. The inhibition of autophagy promotes apoptosis, implicating a novel strategy for the treatment of ER alpha-positive PTC.
