LINC02086 and gastric cancer: Considering our aim to explore the specific possible mechanism of ceRNA in ASTAD, and based on the PCR results indicating high expression of that LINC02086 and LINC0253 in GC cells, we screened mRNAs in the ceRNA that were also highly expressed in ASTAD, and selected MMP3 with the highest log2FC value as the key mRNA for further study.
