Abstract: MiRNA is a class of small endogenous non-coding molecule RNA with regulatory functions,which regulates the target genes at the post-transcriptional level by binding with 3′untranslated regions(3′UTR)specifically.Nuclear factor kappaB(NF-κB)is a kind of significant intranuclear transcription factor.Being activized,it easily combines with the fixed nucleotide sequence in promoter region to initiate gene transcription and participates in the invasion and metastasis of gastric cancer.Recent researches showed that miRNA not only influences on tumor invasion and metastasis by regulating the expression of downstream target gene NF-κB,and itself also could be regulated by NF-κB transcription factors.This essay mainly narrates the expression of microRNA and NF-κB in gastric carcinoma,and summarize the influence to the invasion and metastasis of gastric cancer cells by regulating thier expression interction.

Key words: Gastric cancer, MicroRNA, NF-κB
