BANCR, BRAF activated non-coding RNA,serves as an important regulator in tumorigenesis.

Annotated Information

Name

BANCR: BRAF-activated non-protein coding RNA (HGNC nomenclature) LINC00586 [1]

Alias

LINC00586

Characteristics

BANCR is a four-exon transcript of 693 bp that is found in a 60 kb gene desert region on chromosome 9. The genes proximal to BANCR are not altered by changes in BANCR expression, indicating that this lncRNA is not a cis regulator of neighbouring genes [2].

BANCR locus is enriched for chromatin marks associated with active transcription, and interestingly, the BANCR promoter was shown to be enriched for STAT1 transcription factor binding in HeLa-s3 cells (ENCODE ChIP-seq data) [2].

Expression

BANCR expression is downregulated and correlated with poor prognosis of NSCLC [1].

BANCR is overexpressed in melanoma cells and crucial for melanoma cell migration. Specifically, BANCR expression is significantly lower at the later stages of tumor development, and in tumors that had undergone extensive metastasis[1].

BANCR is upregulated in Eosinophilic esophagitis (EoE) and induces in interleukin-13 (IL-13)-treated primary esophageal epithelial cells [3]

BANCR is downregulated in colorectal cancer tissues [4].

Regulation

Histone acetylation is a key factor in controlling lncRNA BANCR expression [1].

Function

BANCR overexpression suppresses NSCLC cell invasion and metastasis by affecting EMT[1]

BANCR inhibits migration and invasion of NSCLC cells and induces apoptosis, which possibly also affectes EMT [1].

Downregulation of BANCR may be a negative prognostic factor for NSCLC patients, and indicative of poor survival rates and a higher risk for cancer metastasis [1].

BANCR is a novel BRAFV600E-induced lncRNA that regulates melanoma cell migration in vitro in part by regulating expression of CXCL11 [2]. The genes proximal to BANCR are not altered by changes in BANCR expression, indicating that this lncRNA is not a cis regulator of neighbouring genes [2].

BANCR promotes proliferation in malignant melanoma by regulating MAPK pathway activation and this is is not only ERK1/2-dependent but also JNK-dependent[5].

BANCR regulates cell proliferation by targeting p21, and its effects were likely posttranscriptional [4].

BANCR is involved in the development of a variety of cancers, and it is supposed to be used as the biomarker for cancer diagnosis and threapy [1][6][7][8][9][10][11][12].
