| Research Abstract |
MicroRNAs (miRsare) ~22 nucleotide non-coding RNA molecules that regulate gene expression post-transcriptionally. Competitive endogenous RNAs (ceRNAs) sequester miRs to regulate mRNA transcripts containing common microRNA recognition elements. We investigated the relationship among the PTEN, PTENP1 by qRT-PCR in 40 cancer cell lines. In the 40 gastric cancer patients, we found a remarkably strong correlation between the expression revels of the PTEN and PTENP1. Next, we indicates that high expression of miR-223 had a significant adverse impact on the survival of esophageal squamous cell carcinoma patients through repression of the function of FBXW7. We sought that 3'UTR of FBXW7 will be therapy sponge which decoy of onco-miRs targeted FBXW7. However, up-regulated 3'UTR of FBXW7 did not affect the expression of miRs and FBXW7. Next, we suggests that miR-200b regulates the ZEB1/2 in gastric cancer and thus controls EMT in gastric cancer.
