Annotated Information
Name
Approved symbol:MIR205HG
Approved name：MIR205 host gene
HGNC ID HGNC:43562
Previous name：MIR205 host gene (non-protein coding)
Alias symbol：LINC00510
RefSeq ID：NR_145435
Characteristics
MIR205HG is an intergenic 940 bp long non-coding RNA, located on human chromosome chr1q32.2, consisting four exons (GenBank) [1].
Function
MIR205HG is involved in colony formation and migration of HNSCC cells and is required for pro-tumorigenic activities of the mutant p53 protein[1]. Down-regulation of MIR205HG expression significantly reduced cell proliferation, cell migration and clonogenic activity of head and neck cancer cells. Expression of MIR205HG was significantly increased in HNSCC with mutated TP53 when compared with matched non-tumoral tissues. Furthermore, MIR205HG expression levels were significantly higher in tumoral samples with mutant p53 than in tumoral tissues expressing wild-type p53 [1]..
MIR205HG depletes endogenous miR-590-3p leading to elevated levels of ccnb and cdk1 in HNSCCs carrying mutated TP53, thereby leading to increased cell proliferation in head & neck squamous cell carcinoma (HNSCC) [1].
Expression
MIR205HG is overexpressed in tumor samples from TCGA and also in a cohort of HNSCC patients [1].
Regulation
MIR205HG is regulated by p53 through binding to regulatory elements located in the upstream region of the first exon of MIR205HG [1].
Diseases
- Head & neck squamous cell carcinoma (HNSCC) [1]
