Abstract:
Background and objective Progesterone and adiponectin receptor family member 3 (PAQR3) is a recently discovered tumor suppressor gene,which affects the development of a tumor by inhibiting cell proliferation,cell malignant transformation,angiogenesis,and tumor metastasis.This study investigates the expression of PAQR3 in lung cancer and its clinical significance.Methods A total of 106 patients with lung cancer received surgical treatment in hospital,and adjacent normal tissues of these patients were utilized as control group.The diagnosis of all patients was confirmed through clinical pathology.The expression of PAQR3 protein was detected by immunohistochemistry in lung cancer and adjacent normal tissues.The clinical significance of its expression was also investigated.Results The positive expression rate of PAQR3 protein in lung cancer was lower than that in adjacent normal tissues (P＜0.01).The positive expression rate of PAQR3 protein was unrelated to age,tumor size,and gender,but it exhibited a significant relationship with the pathological type and differentiation,TNM staging,and lymph node metastasis (P＜0.05).Kaplan-Meier survival analysis showed that the five-year survival rate of patients with PAQR3 protein positive expression was higher than that in patients with negative expression (P=0.026).Conclusion The expression of PAQR3 protein significantly decreased in lung cancer,indicating that PAQR3 protein plays an important role in the pathogenesis of PAQR3 in lung cancer.
