Gly-tRF targets NDFIP2 (Nedd4 family interacting protein 2) to promote tumor cell migration,75 LeuCAG3′tsRNA binds to the mRNA of ribosomal proteins (RPS28 and RPS15) to enhance the cell apoptosis process,102 and 5′-tRF-Gly directly targets CEACAM1 (carcinoembryonic antigen-related cell adhesion molecule 1) to reduce tumor size and metastasis.77 This evidence concerns the gene RPS15 and neoplasm.
