Annotated Information

Name

FEZF1-AS1:FEZF1 antisense RNA 1[1]

Characteristics

FEZF1-AS1 is a conserved ~2.6-kb RNA transcribed from the plus strand of chromosome 7, on the opposite strand of the gene coding FEZF1 protein (7q31.32), including 611 nucleotides of full complementarity between the frst FEZF1-AS1 exon and FEZF1 exons 1 [1]. FEZF1-AS1 is an lncRNA producing a 2564 bp transcript, located in chromosome 7[2].

It belongs to the category of "Antisense" in lncRNA classification.

Cellular Localization

7q31.32

Function

Downregulation of FEZF1-AS1 expression signifcantly inhibited the CRC cells proliferation, migration and invasiveness, suppressed S-phase entry in vitro, repressed tumor growth and metastasis in vivo, and also reduced its sense-cognate gene FEZF1 mRNA and protein expression in CRC cells[1].

FEZF1-AS1 boost gastric cancer cell proliferation:(I) SP1 accelerated FEZF1-AS1 overexpressioon in gastric cancer; (II) FEZF1 -AS1 caused G1-S arrest contributing to proliferation; (III) FEZF1 -AS1 repressed p21 transcription by recruiting LSD1 causing H3K4me2 demethylation at the p21 promoter in gastric cancer. FEZF1-AS1 promoted gastric cancer cell proliferation and tumorigenesis in vivio and vivo by affecting cell cycle progression.[2].

Disease

  • Colorectal carcinoma[1]
  • Gastric cancer[2]
