Background:
This study investigated the clinical implication of TNK2 expression in esophageal cancer patients' cancer tissue samples.
Methods:
The expression of TNK2 in esophageal cancer tissues and para-carcinoma tissue was assessed with immunohistochemistry and Western blot analysis; besides, the proteins of CDC42, EGFR, and Akt were also analyzed. Then, Kaplan-Meier survival curves of TNK2 protein expression level were assayed with 184 esophageal cancer patients from TCGA database. Moreover, with multiple linear regression analysis, we detected the correlations of TNK2 expression associated with tumor differentiation degree and metastasis status.
Results:
It revealed that TNK2 was highly expressed in the cytoplasm of esophageal cancer tissues compared with para-carcinoma tissue; besides, the proteins of CDC42, EGFR, and Akt were also up-regulated in different levels of esophageal cancer tissues. However, there was no significant difference of the overall survival time of TNK2 protein expression in 184 esophageal cancer patients from TCGA database (p = 0.37). But, in the included study samples of our study, there was positive coefficience between TNK2 protein expression and differentiation degree in esophageal cancer with multiple linear regression analysis [R = 0.928, 95% confidence interval (0.085-0.12)].
Conclusion:
Our results indicated that TNK2 was a potential diagnostic marker and promoted esophageal cancer progression through activating EGFR-AKT signaling.
