RoR can also function as a negative regulator of p53 through interaction with an RNA binding protein, heterogeneous nuclear ribonucleoprotein I. Importantly, a 28-base RoR sequence carrying hnRNP I binding motifs is essential and suffcient for p53 repression. In addition, it can inhibit p53-mediated cell cycle arrest and apoptosis.<ref name="ref2" /> | RoR can also function as a negative regulator of p53 through interaction with an RNA binding protein, heterogeneous nuclear ribonucleoprotein I.

Annotated Information
Name
LINC-ROR:long intergenic non-protein coding RNA, regulator of reprogramming[1]
Characteristics
The RoR gene is 2.6 kb in length, located in chromosome 18 (hg19 chr18:54,721,802-54,739,350), consisting of four exons. [2]
Cellular Localization
18q21.31
Function
LINC-ROR can modulate reprogramming of human differentiated cells to induce pluripotent stem cells.[1]
RoR can also function as a negative regulator of p53 through interaction with an RNA binding protein, heterogeneous nuclear ribonucleoprotein I. Importantly, a 28-base RoR sequence carrying hnRNP I binding motifs is essential and suffcient for p53 repression. In addition, it can inhibit p53-mediated cell cycle arrest and apoptosis.[2]
Linc-RoR functions as an endogenous miRNA sponge for differentiation-related miRNAs. and linc-RoR, miRNAs, and the core TFs can form a regulatory circuit consisting of autoregulatory and dualnegative feedback loops during embryonic stem cell (ESC) self-renewal. This regulatory loop maintains a relative balance in self-renewing human embryonic stem cells (hESCs) to resist slight environmental changes and to elicit a rapid response to strong differentiation signals that promote hESCs differentiation. [4]
Linc-RoR modulates miR-145 levels, a sits overexpression diminishes endogenous miR-145 in self-renewing hESCs and drastically delays the increase in miR-145 upon hESC differentiation.[3]
Linc-RoR can modulate cellular responses during hypoxic stress through modulation of HIF-1a and its downstream targets.[5]
Regulation
RoR-p53 autoregulatory feedback loop where p53 transcriptionally induces RoR expression. [2] Linc-RoR transcription ias mainly controlled by the core TFs Oct4, Sox2, and Nanog.[2]
Diseases
malignant liver cancer [5]
Expression
RoR is highly expressed in embryonic stem cells and iPSCs.[2]
In self-renewing human embryonic stem cells (hESCs), linc-RoR is expressed at a high level and removes trace transcribed miRNAs when hESCs are subjected to temporary and slight differentiation agents.[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]
