Annotated Information
Approved Symbol
DANCR
Approved Name
DANCR: Differentiation antagonizing non-protein coding RNA（HGNC nomenclature). "anti-differentiation ncRNA", "anti-differentiation noncoding RNA", lncRNA-ANCR[1] KIAA0114,"KIAA0114"[2] "small nucleolar RNA host gene 13 (non-protein coding)", SNHG13 "adipogenesis up-regulated transcript 2", AGU2[3]
Characteristics
The DANCR gene is 855-base-pair long noncoding RNA located on human chromosome 4, with the closest adjacent annotated genes located 54.8 kb upstream of (USP46) and 28.7 kb downstream from (ERVMER34-1) the DANCR locus. The DANCR locus consists of three exons and harbors a microRNA (MIR4449) and a snoRNA (SNORA26) in introns 1 and 2, respectively. These small RNAs are not coordinately expressed with DANCR and are not part of the mature DANCR transcript. [1]. DANCR contains another conserved GC-rich region in the first intron, which may be processed as a not-yet-annotated small functional RNA. This notion does, however, require more intensive analysis of the function of DANCR. From an evolutionary perspective, it is of interest that transcription units of DANCR as well as AGD2 are shaped by retrotransposons. AGU2 contains a long terminal repeat (LTR)-like element, which provides its polyA signal.[3]
Function
DANCRsuppresses a genetic program associated with epidermal differentiation. Depleting DANCR in progenitor-containing populations, without any other stimuli, led to rapid differentiation gene induction. In epidermis, ANCR loss abolished the normal exclusion of differentiation from the progenitor-containing compartment. The DANCR lncRNA is thus required to enforce the undifferentiated cell state within epidermis [1].
Regulation
AGU2 induction conteol DANCR regulation[3].
Disease
- Breast Cancer [4]
- Colorectal Cancer [4]

Expression
Long non-coding RNAs-DANCR is a valuable cancer-related lncRNA that its dysregulated expression was found in a variety of malignancies, including hepatocellular carcinoma, breast cancer, glioma, colorectal cancer,gastric cancer, and lung cancer. The aberrant expressions of DANCR have been shown to contribute to proliferation,migration and invasion of cancer cells [4]
