Abstract

Genomic studies demonstrate that, although the majority of the mammalian genome is transcribed, only about 2% of these transcripts are code for proteins. We investigated how the long, polyadenylated Evf2 noncoding RNA regulates transcription of the homeodomain transcription factors DLX5 and DLX6 in the developing mouse forebrain. We found that, in developing ventral forebrain, Evf2 recruited DLX and MECP2 transcription factors to important DNA regulatory elements in the Dlx5/6 intergenic region and controlled Dlx5, Dlx6 and Gad1 expression through trans and cis-acting mechanisms. Evf2 mouse mutants had reduced numbers of GABAergic interneurons in early postnatal hippocampus and dentate gyrus. Although the numbers of GABAergic interneurons and Gad1 RNA levels returned to normal in Evf2 mutant adult hippocampus, reduced synaptic inhibition occurred. These results suggest that noncoding RNA-dependent balanced gene regulation in embryonic brain is critical for proper formation of GABA-dependent neuronal circuitry in adult brain.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
