MAPK6-DT, a divergent lncRNA (long noncoding RNA) of MAPK6 overexpressed in liver tumorigenesis.

Annotated Information

Name

Approved symbol:MAPK6-DT

Approved name:MAPK6 divergent transcript

HGNC ID HGNC:53900

Alias symbol:lncMAPK6

RefSeq ID:NR_156732

Characteristics

MAPK6-DT is a divergent lncRNA (long noncoding RNA) of MAPK6 with chromosomal location at 15q21.2. Divergent lncRNAs, often modulate their nearby genes in cis, are positively-related to their nearby genes. As a divergent lncRNA of MAPK6, lncMAPK6 is co-expressed with MAPK6 in liver tumor and TICs.

Function

LncMAPK6 regulates the expression of MAPK6 through transcriptional activation. LncMAPK6 promotes liver tumor propagation and TIC self-renewal through MAPK6. LncMAPK6 interacts with and recruits RNA polymerase II to MAPK6 promoter, and finally activates the transcription of MAPK6. Through MAPK6 transcriptional regulation, lncMAPK6 drives MARK signaling activation.

Regulation

MAPK6 is critical for the function of lncMAPK6 as after MAPK6 knockout, lncMAPK6 had no effect on liver TIC self-renewal. LncMAPK6 had no effect on tumor invasion if MAPK6 was knockout, further confirming the importance of MAPK6 in lncMAPK6 signaling

Expression

Overexpression of MAPK6 in liver tumor and TICs. Expression profiles of MAPK components were shown as heatmap. Blue denoted low expression and red denoted high expression. [1].

lncMAPK6 overexpression through CRISPRa strategy promoted the self-renewal of liver TICs.[1]

Diseases

Liver cancer [1]
