MIR503HG, a lncRNA which is likely originated at least 370 Myr ago in the tetrapod ancestor, may functions like H19 by promoting miRNA transcription, preferentially in the placenta and in an imprinted manner.

Annotated Information

Name

MIR503HG: MIR503 host gene(HGNC nomenclature)

"H19 X-linked co-expressed lncRNA", H19X, MGC16121[1]

Characteristics

Expression pattern for an X-linked H19 co-expressed lncRNA (H19X, identified as ENSG00000223749 in the Ensembl database), in five tetrapod species.[1]

MIG503HG could potentially promote the transcription of between 2 and 7 miRNAs in different species, such as Human,mouse,Opossum,platyous,xenopus,. This lncRNA (that we name H19X, for H19 X-linked co-expressed lncRNA) is ikely originated at least 370 Myr ago, in the tetrapod ancestor[1].

Fuction

H19X is a neighbour of Rsx, the lncRNA that drives imprinted X-inactivation in marsupials, suggesting that H19X may itself be imprinted. These results suggest that H19X may function like H19, by promoting miRNA transcription, preferentially in the placenta and in an imprinted manner[1].

Expression

Expression pattern appears to have dramatically shifted during evolution, from an ancestral testes-predominant pattern to preferential expression in the chorioallantoic placenta of eutherians[1].

Disease

choriocarcinoma

Evolution

Expression pattern appears to have dramatically shifted during evolution, from an ancestral testes-predominant pattern to preferential expression in the chorioallantoic placenta of eutherians[1].
