Abstract

Introduction: EphA2 is a crucial oncogene in gastric cancer (GC) development and metastasis, and miR-302b can target EphA2 in gastric cancer. This study plans to investigate their relationship and clinical significance in clinical samples.

Materials and Methods: We explored the correlation of the expression of EphA2 and miR-302b, and their clinical significance in the training (n=226) cohort of GC patients, and then validated the results in the validation (n=128) cohort.

Results: miR-302b was remarkably downregulated in GC tissues, while high EphA2 expression were detected, and they were inversely correlated both in mRNA and protein, (r=-0.4209, P<0.0001; r=-0.336, P <0.001, respectively). Furthermore, the pattern of high EphA2 and low miR-302b expression were found to be associated with poor overall survival in stage IV GC patients in both training and validation cohort.

Conclusions: The expression of miR-302b and EphA2 was inversely correlated, and had prognostic significance on GC in clinic.

Keywords: miR-302b, EphA2, gastric cancer
