Abstract
AIM: To investigate the expression of transketolase like-1 (TKTL1) protein and mRNA and to analyze its clinical significance in esophageal squamous cell carcinoma (ESCC).
METHODS: The expression of TKTL1 protein and mRNA was detected by immunohistochemistry and in situ hybridization in 62 ESCC specimens, 31 tumor-adjacent atypical hyperplastic epithelial specimens, and 62 normal esophageal mucosal specimens, respectively.
RESULTS: The positive rates of TKTL1 protein expression in normal esophageal epithelium, tumor-adjacent atypical hyperplastic epithelium and ESCC were 17.7% (11/62), 29.0% (9/31) and 53.2% (33/62), respectively, with significant differences among the three groups (all P < 0.05). TKTL1 protein expression was closely correlated with infiltrative depth, lymphatic metastasis and TNM grade in ESCC (all P < 0.05). The positive rates of TKTL1 mRNA expression in normal esophageal epithelium, tumor-adjacent atypical hyperplastic epithelium and ESCC were 4.8% (3/62), 22.6% (7/31) and 43.5% (27/62), respectively, with significant difference among the three groups (all P < 0.05). TKTL1 mRNA expression was closely associated with infiltrative depth, lymphatic metastasis and TNM grade in ESCC (all P < 0.05). There is a positive correlation between TKTL1 mRNA and protein expression (γp = 0.302, P < 0.01).
CONCLUSION: TKTL1 expression may be associated with the development, invasion and metastasis of ESSC.
