CCAT2, a novel long noncoding RNA transcript (lncRNA) harboring a single nucleotide polymorphism rs6983267 SNP, promotes tumor growth, metastasis, and chromosomal instability, including colon cancer[1] and non-small cell lung cancer [2]
Contents
Annotated Information
Name
CCAT2, colon cancer-associated transcript 2 (CCAT2) (HGNC nomenclature)
Characteristics
CCAT2 is transcribed from chromosome 8q24, a very conserved region harboring a single nucleotide polymorphism rs6983267, which has been identified in various genome-wide association studies . [2]
Function
CCAT2 promotes cancer growth and metastasis and induces chromosomal instability. CCAT2 can regulates MYC transcription. CCAT2 responds to WNT signaling. [1] CCAT2 is a lung adenocarcinoma-specific lncRNA and promotes invasion of NSCLC and highlight its potential as a biomarker for lymph node metastasis.[2]
Regulation
rs6983267 status affects the CCAT2 expression, providing an additional mechanism linking the risk allele of rs6983267 with higher CRC risk. CCAT2 shows significant association with MYC expression levels, suggesting that the SNP status may also affect CCAT2 function as an RNA transcript. [1]
Diseases
Expression
CCAT2 is expressed at high levels in MSS CRC tumor tissues and influences MYC levels, but has very low-level expression in normal colon tissues. [1]
