Transcriptomic Nomeclature
CAHM: colon adenocarcinoma hypermethylated(non-protein coding)(HGNC nomenclature)
LINC00468, "long intergenic non-protein coding RNA 468"[1]
Characteristics
CAHM located adjacent to the gene QKI, is hypermyethylated in colorectal neoplasia.[1]
Function
CAHM showed specially hypermethylated in colorectal neoplasia compared with lung, prostate and breast cancer[1].
The levels of hypermethylated CAHM of CRC patients were increased in blood than normals. Moreover, the increaseing levels of mythylated CAHM was correlated with advancing disease stage, which may act as a potential marker for CRC substypes.
Expression
CAHM and its neighboring gene QKI were both downregulated in colorectal neoplasia because of hypermethylation, which suggests their high positive correlation.
