Neonatal mice exposed to a high-fat diet in utero influence the behaviour of their nursing dam.

ABSTRACT: The behaviour of a nursing dam influences the development, physiology, and behaviour of her offspring. Maternal behaviours can be modulated both by environmental factors, including diet, and by physical or behavioural characteristics of the offspring. In most studies of the effects of the environment on maternal behaviour, F0 dams nurse their own F1 offspring. Because the F1 are indirectly exposed to the environmental stressor in utero in these studies, it is not possible to differentiate between effects on maternal behaviour from direct exposure of the dam and those mediated by changes in the F1 as a consequence of in utero exposure. In this study, we used a mouse model of high-fat (HF) diet feeding, which has been shown to influence maternal behaviours, combined with cross-fostering to d
