Name
Approved symbol : MIR31HG: MIR31 host gene
Alias symbols: LOC554202, hsa-lnc-31, LncHIFCAR
HGNC ID: HGNC:37187
LncBook transcript ID: HSALNT0289179
Characteristics
The LOC554202 gene which does not contain an open reading frame is located at chromosome 9p21.3. LOC554202 is transcribed from 4 exons resulting in a spliced transcript of ~2.2 kb[1].
Function
Higher expression of Loc554202 in breast cancer tissues was associated with larger tumor size and a more advanced clinical stage, suggesting that the expression of Loc554202 could be used as a diagnostic and prognostic breast cancer marker[1].
Hsa-lnc-31 has an overall effect in sustaining myoblast proliferation and counteracting differentiation[2].
Disease
- Breast cancer
Expression
Loc554202 is significantly increased compared with normal control, and associated with advanced pathologic stage and tumor size. Moreover, knockdown of Loc554202 decreased breast cancer cell proliferation, induced apoptosis and inhibits migration/invasion in vitro and impeded tumorigenesis in vivo[1].
LOC554202 is down-regulated in the TNBC cell lines of basal subtype and over-expressed in the luminal counterparts, CpG island methylation plays an important role in silencing of the LOC554202 genes[1].
Hsa-lnc-31 RNA is abundant in proliferating human myoblasts and is downregulated upon differentiation[2].
