目的 观察鼻咽癌患者癌组织中RhoA蛋白-Rho激酶蛋白表达情况。方法 收集增城市人民医院2009年2月—2014年6月耳鼻喉科住院治疗,进行活检的鼻咽癌患者切除标本共62例,包括癌组织及癌旁组织。通过SABC免疫组织化学法检测患者癌组织及癌旁组织中RhoA蛋白-Rho激酶蛋白表达情况。结果 鼻咽癌组织RhoA蛋白阳性表达率及Rho激酶蛋白阳性率高于癌旁组织(P=0.00);鼻咽癌癌组织RhoA及Rho激酶表达在年龄及性别分布上无差异,而TNM分期中Ⅲ期+Ⅳ期RhoA及Rho激酶表达阳性率高于Ⅰ期+Ⅱ期患者,同时存在淋巴结转移患者其RhoA及Rho激酶表达阳性率高于未转移患者。结论 鼻咽癌患者癌组织中RhoA蛋白及Rho激酶表达阳性率高,TNM分期越高及存在淋巴结转移者其RhoA蛋白及Rho激酶表达阳性率越高。RhoA-Rho激酶信号通路参与了鼻咽癌发生发展的过程。
Objective To observe the expression of RhoA-Rho kinase protein in patients with nasopharyngeal carcinoma tissue. Methods Collecting 62 cases of patients with nasopharyngeal carcinoma who hospitalized and hadbiopsyof specimens, including carcinoma tissues and adjacent tissues in department of otolaryngology-head and neck surgery from February 2010 to October 2014. The expression of RhoA-Rho kinase protein in carcinoma tissues and adjacent tissues was detected with SABC immune histochemical method. Results Positive expression rate of nasophryngeal carcinoma tissue RhoA protein and Rho kinase protein was significantly higher than that of adjacent tissues, and there was no obvious difference in age and sex between the expression of nasopharyngeal carcinoma tissue RhoA and Rho kinase(P=0.00), while patients being in the third and fourth periods of TNM stage had a higher positive expression rate of RhoA and Rho kinase than those being in the first and second periods. At the same time, RhoA and Rho kinase positive expression rate in patients with lymph node metastasis was higher than that in those without lymph node metastasis. Conclusion Positive expression rate of RhoA protein and Rho kinase in patients with nasopharyngeal carcinoma. The higher TNM stage is, the higher positive expression rate of RhoA protein and Rho kinase in lymph node metastasis is. RhoA-Rho kinase signaling pathways involved in the occurrence and development of nasopharyngeal carcinoma.
