Chromosome
1q32.3
Characteristics
FLVCR1-AS1 is a 2-exon gene and it appears to have arisen after duplication of the hFLVCR locus.[1] FLVCR1-AS1 has two transcripts and both exon 2 isoforms share the same polyA signal.(Figure A )
Expression
FLVCR1-AS1 is expressed in a wide variety of tissues, including colon tumor, uterine tumor, placenta, lung tumor, brain tumor, neural tissue, fatal liver/spleen, bone marrow, aorta and kiney.(Figure C ) [1]
lncRNA FLVCR1‐AS1 was extremely up‐regulated in HCC tissues and cell lines. [2]
Function
Both splice forms of the FLVCR1-AS1 cDNA encode identical 103 aa ORFs that include a 163 nt MER41D interspersed repeat. [1]
FLVCR1‐AS1 acted as a competitive endogenous RNAs to sponge miR‐513c which targeted the mRNA of MET for degradation. By directly sponging miR‐513c, FLVCR1‐AS1 increased MET expression in HCC, and then promoted HCC progression.[2]
Disease
hepatocellular carcinoma [2]
