In conclusion, miR-140-3p directly bound to SNHG12 in GC and down-regulated the expression of SNHG12, reduced the binding of SNHG12 and HuR, inhibited the nuclear transportation and the binding between HuR and mRNA of FAM83B, thereby downregulating the transcription of FAM83B, and eventually, the growth and metastasis of GC were inhibited (Fig. 10). Here, ELAVL1 is linked to gastric cancer.
