Abstract: Objective To detect the expression of KCNK5 in papillary thyroid carcinoma(PTC)tissues and investigate its correlation with clinicopathological characteristics and prognosis in patients with PTC. Methods Immunohistochemistry and western blotting were used to detect the expression of KCNK5 in PTC tissues and paraneoplastic normal tissues, and the relationship between KCNK5 and the clinicopathological characteristics of PTC was analyzed; moreover, the relationship between KCNK5 and the prognosis of PTC was analyzed using the KM Plotter database. Results Immunohistochemical results showed that KCNK5 was expressed in the cytosol, nuclear membrane, and cytoplasm of PTC cells, and KCNK5 was either not expressed or weakly positively expressed in paraneoplastic normal tissues. Western blotting and immunohistochemical semi-quantitative integration showed that the expression level of KCNK5 in PTC tissues was significantly higher than that in paraneoplastic normal tissues(P<0.05). KCNK5 expression was positively correlated with TNM stage and lymph node metastasis in PTC patients(both P<0.05); multivariate logistic regression analysis further indicated that KCNK5 expression was related to lymph node metastasis(P<0.05). Kaplan-Meier analysis showed that the survival rate of patients with a high KCNK5 expression was significantly lower than that of patients with a low KCNK5 expression(P<0.01). Conclusion KCNK5 is closely associated with lymph node metastasis and prognosis of PTC patients and has the potential to become an indicator of PTC prognosis.

[3] This study aims to evaluate the level of expression of cyclin E2 in hypopharyngeal cancer and its relationship with clinical characteristics as well as prognosis. MethodsThe protein levels of cyclin E2 in tumor tissues and adjacent normal tissues were assessed by immunohistochemistry staining in 50 cases of hypopharyngeal cancer. The relationship between the expression level of cyclin E2 and clinical data was analyzed using the SPSS software. ResultsProtein levels of cyclin E2 in hypopharyngeal cancer were higher than protein levels of cyclin E2 in normal tissue(Z=-5.764,P=0.000). The cyclin E2 level in tumor tissue correlated with the tumor staging(Z=-1.995, P=0.046)and lymph node metastasis(Z=-2.176, P=0.030). The 5-year survival rates of patients with cyclin E2 positive and negative expression were 40.2% and 81.8%, respectively. Patients with high expression levels of cyclin E2 had a lower survival rate(χ=6.317, P=0.012). ConclusionThe abnormal expression of cyclin E2 protein in tumor tissues indicates that cyclin E2 may be involved in the development of hypopharyngeal cancer and could be a potential diagnostic and prognostic molecular marker..
