Outline
To investigate the expression and clinical significance of protein-O-fucosyltransferase 1 in non-small cell lung cancer (NSCLC), so as to provide a reference for the diagnosis and treatment of NSCLC.
The expression of POFUT1in NSCLC was determined by TCGA, UALCAN database and immunohistochemistry. Based on the clinical data form TCGA database were extracted for survival analysis by Kaplan-Meier method, and analysis of the effect of POFUT1 mRNA expression level on prognosis of patients with NSCLC.
POFUT1 was highly expression in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) tissues (all P<0.05). The expression level of POFUT1 mRNA in LUAD was correlated with clinical stage (P<0.001) and that in LUSC was correlated with tumor size (P<0.001). COX regression analysis showed that high mRNA expression of POFUT1 (P=0.012), tumor size, clinical stage and lymph node metastasis were associated with the prognosis of LUAD patients (all P<0.001), and clinical stage III-IV was an independent risk factor for LUAD patients. Tumor size (P=0.001), clinical stage III-IV (P=0.006) and high expression of POFUT1 mRNA (P=0.049) were associated with the prognosis of LUSC patients, and tumor size greater than 5cm and high expression of POFUT1 were independent risk factors for LUSC patients. The survival analysis result showed that the survival rate of patients with high expression of POFUT1 was significantly lower than that of patients with low expression.
POFUT1 is highly expressed in NSCLC tissues, and high POFUT1 expression is correlated with poor prognosis in patients. POFUT1 can serve as a biomarker for prognostic evaluation of NSCLC.
