Here we demonstrate that natural antisense transcripts (NATs), which are abundant in mammalian genomes, can function as repressors of specific genomic loci and that their removal or inhibition by AntagoNAT oligonucleotides leads to transient and reversible upregulation of sense gene expression. As one example, we show that Brain-Derived Neurotrophic Factor (BDNF) is under the control of a conserved noncoding antisense RNA transcript, BDNF-AS, both in vitro and in vivo. 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. By providing additional and analogous examples of endogenous mRNA upregulation, we suggest that antisense RNA mediated transcriptional suppression is a common phenomenon. In sum, we demonstrate a novel pharmacological strategy by which endogenous gene expression can be upregulated in a locus-specific manner.
