LINC01667 and gastric cancer: To further confirm the relationship between LINC01667 and miR-138-5p, LINC01667 was overexpressed (Figure 6D) and the results revealed that the expression of miR-138-5p was significantly upregulated in gastric cancer cells treated with BD, while overexpression of LINC01667 could inhibit the expression of miR-138-5p (Figure 6E).
