Abstract
miR-25 was identified as an essential oncogene by promoting the growth and metastasis through TOB1 in gastric cancer (GC). The function of the single nucleotide polymorphism (SNP) located in the mature region of miR-25 (rs41274221) has not been investigated. In this study, we aimed to explore the involvement of rs41274221 in miR-25 in gastric cancer. We found that SNP rs41274221 in miR-25 was participated in the occurrence of GC by acting as a tumor protective factor associating with the tumor growth and metastasis. Besides, further investigation found that upregulation of miR-25 with AA genotype could attenuate the proliferation and invasion of tumor cells caused by wild-type miR-25. The dual-luciferase reporter assay also confirmed that miR-25 harbored the A allele which caused an incapacitation of binding at the TOB1. In conclusion, rs41274221 in miR-25 was a subgroup which may protect the patients from further growth and metastasis of gastric cancer and might serve as a novel biomarker for the disease.Entities:
