ABSTRACT
OBJECTIVE@#To investigate the expression of ubiquitin and cullin-1 (cul-1) in benign and malignant lesions of the lung and to determine their clinicopathological significance.@*METHODS@#EnVison immunohistochemistry was used to detect the expression of ubiquitin and cul-1 in the conventional paraffin-embedded sections from the specimens of lung cancer (n = 80) and benign lesion tissues of the lung (n = 20). We also analyzed the relation of the expression of ubiquitin and cul-1 with the clinical stage, differentiation, and with or without lymphatic metastasis.@*RESULTS@#The positive rates of ubiquitin and cul-1 were significantly higher in lung cancer (51.3% and 60.0%) than those in benign lesion tissues of the lung (20.0% and 30.0%; P < 0.05). Positive rates of ubiquitin and cul-1 were all significantly lower in the middle and high-differentiated, Stage I approximately II, and no lymphatic metastasis patients with lung cancer than those in no- or low-differentiated, Stage III approximately IV, and lymphatic metastasis patients with lung cancer tissues (P < 0.01 approximately 0.05). High consistency was found between the positive expression of ubiquitin and cul-1 in lung cancer tissues (chi(2) = 4.04, P < 0.05).@*CONCLUSION@#Expression of ubiquitin and cul-1 in lung cancer tissues may be closely related to the carcinogenesis, progression, clinical biological behaviors, and prognosis of lung cancer.
