Contents
Annotated Information
Name
BDNF-AS:BDNF antisense RNA 1 (HGNC nomenclature)
BDNF-AS1, BT2A, BT2B, BT2C, BT2D, NCRNA00049, "non-protein coding RNA 49" [1]
LncBook ID: HSALNT0288893.
Characteristics
Genomic organization of the human BDNF locus showing[1]
BDNF-AS is approximately 200 kb downstream from the BDNF promoter and it is located on the positive strand of chromosome-11. Transcription from this site gives rise to 16–25 splice variant long ncRNAs with 6–8 exons8. Exon-5 of BDNF-AS, which contain 225-nucleotides of full complementarity to BDNF mRNA (overlapping) and exon-4 (non-overlapping) are common between all these variants . [1]
It belongs to the category of "Antisense" in lncRNA classification[1].
Function
Antisense-mediated regulation of sense mRNA and protein[1]
BDNF-AS tonically represses BDNF sense RNA transcription by altering chromatin structure at the BDNF locus, which in turn reduces endogenous BDNF protein and function[1].
BDNF-AS represses chromatin by recruiting Polycomb Repressive Complex 2 (PRC2) to the BDNF promoter region[1].
BDNF-AS siRNA induces activation of the BDNF–TrkB–PI3K/Akt pathway following hypoxia/reoxygenation(H/R)-induced neurotoxicity[2].
Expression
BDNF-AS mRNA levels are generally 10–100 fold higher than BDNF-AS transcript, except in testis, kidney, and heart, which contain equal or higher levels of BDNF-AS. Both transcripts are expressed in brain, muscle and embryonic tissues. BDNF mRNA levels were relatively low in all post-natal tissues examined except in brain, bladder, heart, and skeletal muscle. In rhesus monkey and mouse tissues, both transcripts are co-expressed in many tissues, which suggest BDNF-AS potential for regulation of BDNF mRNA[1].
BDNF expression was significantly downregulated in patients with cerebral infarction, whereas the expression of BDNF-AS was significantly upregulated. In both human cortical neurons (HCN2) and human astrocytes, H/R significantly induced the expression of BDNF-AS, but significantly decreased BDNF expression[2].
