Species differences in central oxytocin receptor gene expression: Comparative analysis of promoter sequences

Abstract

The distribution of oxytocin binding sites in the brain is highly variable among mammals. Using two species of microtine rodents (voles) with strikingly different patterns of oxytocin binding sites in the brain, we demonstrate that these differences are due to differences in region specific gene expression and not post-translational processing. The distribution of oxytocin receptor mRNA closely resembles the distribution of oxytocin receptor binding sites in both species. Analysis of the 5' flanking region of the oxytocin receptor gene from both species reveals few differences in potential regulatory elements which could explain the differences in gene expression. These data suggest that species differences in oxytocin receptor binding are due to species differences in: i) distant DNA sequences further upstream or downstream which may influence expression; ii) the distribution of regulatory proteins such as transcription factors in the brain or iii) epigenetic factors, such as prenatal and perinatal environment which may affect gene expression in the adult.

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.
