摘要
本研究旨在探讨 P 物质在宫颈鳞状细胞癌中的表达和功能。研究收集了本院 20 例宫颈鳞状细胞癌患者的癌组织和邻近组织。通过免疫组化和 Western 印迹分析检测 P 物质的表达。用不同浓度的 P 物质处理宫颈鳞癌细胞株 SiHa，用 EdU 试验检测 SiHa 细胞的增殖情况，用 transwell 试验检测 SiHa 细胞的侵袭能力。通过 Western 印迹分析检测 ERK1/2 的磷酸化和 MMP9 的表达。结果表明，P 物质在宫颈鳞状细胞癌细胞的细胞质和部分细胞膜中均有表达。宫颈癌组织中物质 P 的表达明显高于邻近组织。与对照组相比，物质 P 能显著促进 SiHa 细胞的增殖和侵袭，并激活 ERK1/2 的磷酸化和上调 MMP9 的表达。总之，P 物质在宫颈鳞状细胞癌中高表达，能促进宫颈癌细胞的增殖和侵袭。其机制与激活ERK1/2途径上调MMP9有关。
Substance P is overexpressed in cervical squamous cell carcinoma and promoted proliferation and invasion of cervical cancer cells in vitro.
This study aimed to investigate the expression and function of substance P in cervical squamous cell carcinoma. Cancer tissues and adjacent tissues of 20 patients with cervical squamous cell carcinoma in our hospital were collected. The expression of substance P was detected by immunohistochemistry and Western blot analysis. Cervical squamous cell carcinoma line SiHa was treated with different concentrations of substance P. The proliferation of SiHa cells was detected by EdU assay, and the invasion ability of SiHa cells was detected by transwell assay. The phosphorylation of ERK1/2 and the expression of MMP9 were detected by Western blot analysis. The results showed that substance P was expressed in the cytoplasm and some cell membranes of cervical squamous cell carcinoma cells. The expression of substance P in cervical cancer tissues was significantly higher than that in the adjacent tissues. Compared with the control group, substance P significantly promoted the proliferation and invasion of SiHa cells in a concentration dependent manner and activated the phosphorylation of ERK1/2 and upregulated the expression of MMP9 in SiHa cells. In conclusion, substance P is highly expressed in cervical squamous cell carcinoma and can promote cervical cancer cell proliferation and invasion. The mechanism is related to the activation of ERK1/2 pathway to upregulate MMP9.
期刊介绍：
The Journal publishes original papers concerning investigations by histochemical and immunohistochemical methods, and performed with the aid of light, super-resolution and electron microscopy, cytometry and imaging techniques. Coverage extends to:
functional cell and tissue biology in animals and plants;
cell differentiation and death;
cell-cell interaction and molecular trafficking;
biology of cell development and senescence;
nerve and muscle cell biology;
cellular basis of diseases.
The histochemical approach is nowadays essentially aimed at locating molecules in the very place where they exert their biological roles, and at describing dynamically specific chemical activities in living cells. Basic research on cell functional organization is essential for understanding the mechanisms underlying major biological processes such as differentiation, the control of tissue homeostasis, and the regulation of normal and tumor cell growth. Even more than in the past, the European Journal of Histochemistry, as a journal of functional cytology, represents the venue where cell scientists may present and discuss their original results, technical improvements and theories.
