APOA1-AS, an antisense transcript of APOA1, functions as a negative transcpritional regulator of APOA1 by modulating distinct histone methylation patterns.

Annotated Information

Name

Figure 1. APO gene cluster and APOA1-AS NAT organization on human chromosome 11. [1].

APOA1-AS: Apolipoprotein A-1 antisense RNA(HGNC nomenclature)

Characteristics

APOA1-AS is transcribed from the positive strand of chromosome 11 and has two exons, positioned ~20kb apart. It shares a 123 nucleotide-long region overlapping with the fourth exon of APOA1 mRNA.(Figure 1)

Function

Figure 2. Characterization of the expression profiles of APOA1 and APOA1-AS. [1].

APOA1-AS functions in cis to modulate histone methylation patterns of APOA1, through the recruitment of LSD1 and PRC2. Targeting APOA1-AS using short antisense oligonucleotides will enhance APOA1's expressopn level. APOA1-AS also regulates the transcription of APOC3 and APOA4, which are located in close proximity on the chromatin. [1]

Expression

APOA1 and APOA1-AS are expressed in all tissues examined, but there their expression levels are quite different. APOA1 mRNA’s expression level is highest in liver, small intestine and colon, while APOA1-AS is highly expressed in ovary, cervix, testis and thyroid. The ratio of APOA1/APOA1-AS varies among the tissues examined.(Figure 2) [1]

Note: For each edit version that is contributed by a specific person, his/her contribution is quantified as its edit quality multiplied by its edit quantity; the edit quantity amounts to the edit distance in comparsion with its previous version (that is, the minimum number of edit operations required to transform one string into the other), and the edit quality corresponds to whether the edit persists in comparison with the last version, ranging from -1, when the edit is entirely reverted (short-lived), to 1, indicating that the edit is totally preserved in the last version (long-lived). Please also note that contribution quantification may take time to reflect recent edits.
*Since one person may perform many discontinuous edits for a wiki page, contribution score is the sum of quantified contributions over all participated edits.
#Multiple successive edits provided by a researcher are counted as one edit.
ΛSummed edit quantity is the sum of edit quantities over all participated edits.
Averaged edit quality is the edit quality normalized over all participated edits.
