JADRR is a key functional link that connects the DDR to histone H4 acetylation and play a potential role in breast tumorigenesis.
Contents
Annotated Information
Name
JADRR: JADE1 adjacent regulatory RNA (HGNC nomenclature)
INXS:lncRNA-JADE [1]
Characteristics
LncRNA-JADE,an independent transcript which contains no overlapping sequence with the transcripts from its neighbouring genes, is transcribed in the opposite orientation to the Jade1 gene, while its human homologue has the same orientation as Jade1.LncRNA-JADE and Jade1 genes have distinct promoters at the chromosomal region 3qB in mouse[1].
Function
LncRNA-JADE as an important link that connects the DNA damage signalling to the Jade1-mediated H4 acetylation[1].
LncRNA-JADE may supress the DNA damage-induced apoptosis and decrease the sensitizition of cells to DNA damaging agents[1].
LncRNA-JADE promotes cell proliferation, inhibits DNA damage checkpoints, and reduces the cellular sensitivity to DNA damaging drugs, suggesting that lncRNA-JADE possibly has the proto-oncogene properties[1].
Regulation
The transactivation of lncRNA-JADE is regulated by the ATM-NF-κB signalling in the DDR [1]
Diseases
- Breast cancer[1]
Expression
lncRNA-JADE showed very low or undetectable expression levels in all of normal breast tissues. However, breast tumours exhibited overexpressed lncRNA-JADE, some tumour samples even had high or very high levels of lncRNA-JADE[1].
