Relation Between Obesity and Blunted Striatal Response to Food Is Moderated by Taq IA A1 Allele

Abstract

The dorsal striatum plays a role in consummatory food reward, and striatal dopamine receptors are reduced in obese individuals, relative to lean individuals, which suggests that the striatum and dopaminergic signaling in the striatum may contribute to the development of obesity. Thus, we tested whether striatal activation in response to food intake is related to current and future increases in body mass and whether these relations are moderated by the presence of the A1 allele of the Taq IA restriction fragment length polymorphism, which is associated with dopamine D2 receptor ( DRD2 ) gene binding in the striatum and compromised striatal dopamine signaling. Cross-sectional and prospective data from two functional magnetic resonance imaging studies support these hypotheses, which implies that individuals may overeat to compensate for a hypofunctioning dorsal striatum, particularly those with genetic polymorphisms thought to attenuate dopamine signaling in this region.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Enhanced activity in brain regions that process palatability could make obese subjects favour food over other natural reinforcers, whereas decreased activation of dopaminergic targets by actual food consumption might lead to overconsumption to compensate for weak D2R-mediated signalling.

    “An enhanced activity in brain regions that process palatability could make obese subjects favour food over other natural reinforcers, whereas decreased activation of dopaminergic targets by the actual food consumption might lead to overconsumption as a means to compensate for weak D2R-mediated signalling (93).”

  • Blunted DA activation by consumption of drug or food could trigger overconsumption to compensate for the blunted reward circuit response.

    “Since this is not what is seen in the clinic, it was suggested that blunted DA activation by consumption (of drug or food) could trigger overconsumption to compensate for the blunted response of the reward circuit (46).”

    From The Addictive Dimensionality of Obesity (2013) · cites this paper as [46]

  • In contrast to adult research, studies using only adolescent participants found the A1 allele is associated with decreased reward reactivity in ventral and dorsal striatum.

    “In contrast to the adult research, the few studies using only adolescent participants found that the A1 allele is associated with decreased reward reactivity in ventral (Stice and Dagher 2010) and dorsal (Stice, Spoor et al. 2008) striatum.”

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.
