摘要

背景与目的：内质网分子伴侣29(endoplasmic reticulum molecular chaperons 29，ERp29)是一种内质网应激蛋白，其高表达与肿瘤转移相关。本研究旨在探讨ERp29在小鼠腹水型肝癌高、低淋巴道转移株中的表达及与肝癌淋巴道转移的关系。方法：构建小鼠腹水型肝癌细胞株(高转移株Hca-F、低转移株Hca-P)淋巴道转移动物模型，通过免疫组织化学、蛋白质印迹法(Western blot)和流式细胞仪等方法检测ERp29在Hca-F、Hca-P细胞株中的表达情况。结果：免疫组织化学检测结果显示，ERp29在Hca-F、Hca-P中均呈阳性表达，定位于细胞质，部分细胞核也有表达。Western blot检测结果显示，ERp29在Hca-F、Hca-P中的表达吸光度值分别为0.97±0.03和1.17±0.03，ERp29在Hca-F细胞株中的表达(吸光度值)明显低于Hca-P，差异有统计学意义(P＜0.01)。流式细胞仪检测结果显示，ERp29在Hca-F细胞株中的相对荧光强度值(375.27±47.33)显著低于Hca-P(623.91±46.80)，差异有统计学意义(P＜0.01)。结论：ERp29在小鼠腹水型肝癌细胞株Hca-F和Hca-P均有表达，且在Hca-F中表达较低，而在Hca-P中表达较高。ERp29可能与肝癌淋巴道转移密切相关。

Abstract

Background and purpose: ERp29 belongs to endoplasmic reticulum stress proteins and might play roles in neoplasm metastasis. This study aimed to investigate the expression of ERp29 in Hca-F and Hca-P cells and to elucidate its role in lymphatic metastasis. Methods: Immunohistochemistry

Western blot and flow cytometry analysis were used to detect the expression of ERp29 in Hca-F and Hca-P. Results: The results of immunohistochemistry suggested that ERp29 protein was located at cytoplasm of hepatic cells and some were also detected in the nucleus. The results of western blot suggested that ERp29 had positive expression in Hca-F and Hca-P cells. Its expression in Hca-F cells was apparently lower than that in Hca-P cells. And there was statically different between Hca-F and Hca-P cells (P0.01). The relative fluorescence intensity of ERp29 protein was significantly lower in Hca-F cells (375.27±47.33) than that in Hca-F cells (623.91±46.80) by flow cytometry (P0.01). Conclusion: The different expression of ERp29 may be related to the potential ability of tumor lymphatic metastasis in Hca-F and Hca-P cells.
