LINC-ROR, a long non-coding RNA gene that regulates the reprogramming of pluripotent stem cells.
Contents
Annotated Information
Name
Approved symbol: LINC-ROR
Approved name: long intergenic non-protein coding RNA, regulator of reprogramming
HGNC ID: HGNC:43773
Previous names: 7SK, 7SK small nuclear
Alias symbols: lincRNA-RoR; lincRNA-ST8SIA3; ROR
RefSeq ID: NR_048536
Characteristics
The LINC-ROR gene is 2.6 kb in length, located in chromosome 18 (18q21.31), consisting of four exons [1].
Function
LINC-ROR is first found to modulate reprogramming of human induced pluripotent stem cells. LINC-ROR is p53 repressor in response to DNA damage [2].
LINC-ROR can suppress p53 translation through direct interaction with the heterogeneous nuclear ribonucleoprotein I (hnRNP I), and inhibit p53-mediated cell cycle arrest and apoptosis [1].
LINC-ROR also functions as an endogenous miRNA sponge and antagonizes miR-145 to critically regulate the levels of pluripotency transcription factors Oct4, Sox2, and Nanog, in order to ensure embryonic stem cell self-renewal [3][4].
A competition for miR-145 between linc-RoR and mRNAs encoding the core TFs[4].
LINC-ROR is involved in modulation of hypoxia-signaling pathways through modulation of HIF-1a and its downstream targets [5].
Regulation
LINC-ROR and p53 form a RoR-p53 autoregulatory feedback loop where p53 transcriptionally induces RoR expression [1].
LINC-ROR transcription is mainly controlled by the core TFs Oct4, Sox2, and Nanog [2][3][4].
Diseases
malignant liver cancer [5]
Expression
LINC-ROR is highly expressed in embryonic stem cells and iPSCs [1].
In self-renewing human embryonic stem cells (hESCs), LINC-ROR is expressed at a high level [3][4].
LINC-ROR expression is increased in hypoxic regions within tumor cell xenografts in vivo and is highly expressed in extracellular RNA released by hepatocellular cancer (HCC) cells during hypoxia [5].
