Individual differences in emotional expressivity predict oxytocin responses to cortisol administration: relevance to breast cancer?

Tops, Mattie, van Peer, Jacobien M., Korf, Jakob·2007·Biological Psychology

Abstract

Reduced emotional expression has been consistently related to susceptibility or fast progression of breast cancer. Breast cancer development and reduced emotional expression have both been related to rejection- and separation-related conditions. The neuropeptide oxytocin is low in response to rejection or separation. Recent results suggest that oxytocin may protect against the development of breast cancer and slow its progression. In the present study, we investigated if individual differences in emotional expressivity relate to basal or cortisol-stimulated plasma oxytocin. Healthy female subjects were treated with placebo or 35mg of cortisol orally in a double-blind within-subject study. Seventy minutes later, blood was sampled for determination of oxytocin and cortisol levels. We found an interaction between treatment condition and Emotional Expression-out scores: after cortisol treatment, oxytocin levels increased proportional to Emotion Expression-out score. These preliminary findings provide a potential mechanism for associations in the literature between emotional expressive behavior and breast cancer.

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.
