For example, under hypoxia, Goodarzi et al. found that tRFAsp-GTC and tRFGly-TCC produced by breast cancer cells competitively bind YBX1 and replace the 3′UTR in YBX1, resulting in reduced stability of endogenous oncogene transcripts, thereby inhibiting tumor cell proliferation 40. This evidence concerns the gene YBX1 and neoplasm.
