“GAS5”的意思、由来-开放百科全书

GAS5 noncoding RNA, which accumulates in growth arrested cells, acts as a decoy hormone response element for the glucocorticoid receptor (GR) and hence blocks the upregulation of gene expression by activated GR.^[3]^[4]

A number of studies have linked GAS5 to apoptosis and it may play a role in the progression of some types of cancer.^[5]^[6]^[7]

The GAS5 introns host several snoRNA sequences, including SNORD81, SNORD47, SNORD80, SNORD79, SNORD78, SNORD44, SNORD77, SNORD76, SNORD75 and SNORD74.^[2]^[8]^[9]^[10] These intronic sequences are more conserved than the exons of the host gene, these sorts of genes are often called "inside-out genes".^[11]

It was recently discovered that the nonsense-mediated degradation pathway can regulate the function of the GAS5 in mammalian cells.^[12]
