Abstract
Homozygous Groggy dams, which carry a Cacna1a missense mutation, often
show no interest in their offspring, leading to frequent offspring deaths due to lack of
nurturing. The present study aimed to clarify whether the Cacna1a
mutation contributes to impaired attachment behaviors between dam and offspring. The open
field test showed that homozygous female rats exhibited markedly short travel distance,
whereas no difference was found between the motor activity of heterozygous females and
that of wild types (WT). A series of behavioral tests was performed to compare the
mother–offspring relationship between WT and heterozygous rats. Performance in the pup
retrieval test was significantly less successful in heterozygous than WT dams. During the
experiment, heterozygous dams spent significantly less time licking and crouching than WT
dams. The offspring dam-seeking behavior test revealed that heterozygous pups’
vocalizations were significantly less frequent and shorter than those of WT pups. Although
no significant difference was found between WT and heterozygous offspring in the olfactory
sense test, using a piece of chocolate, heterozygous pups took significantly longer to
reach a sample of the dam’s bedding. Taken together, these findings suggest that the
Cacna1a mutation impairs both the dam’s maternal behavior and the
offspring’s attachment behavior toward the 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 discriminate between these effects. We tested whether the diet of the F0 dam or the exposure experienced by the F1 pups in utero is the most significant predictor of maternal behaviour. Neither factor significantly influenced pup retrieval behaviours. However, strikingly, F1 in utero exposure was a significant predictor of maternal behaviour in the 15 min immediately following pup retrieval while F0 diet had no discernable effect. Our findings suggest that in utero exposure to HF diet programmes physiological changes in the offspring which influence the maternal behaviours of their dam after birth.

Abstract
Objectives: Early life represents a sensitive and critical period for an individual. Nutrition plays a crucial role in the maturation and functional development of the central nervous system. Inadequate nutrition before birth and during the postnatal life can seriously interfere with brain development and lead to behavioral and neurological disorders such as learning disabilities and psychiatric diseases. In addition, the quality of mother-infant interactions represents an important adaptive pathway that prepares offspring for the conditions of life. In this work, we asked if protein malnutrition alters maternal care and offspring development and if these phenotypes can be transmitted to next generation.Methods: Female mice were fed with a normal or hypoproteic diet during pregnancy and lactation. Nurturing behaviors, i.e. arched, blanket and passive nursing, and liking and grooming of the pups, were evaluated from postnatal day 1 (PD1) to postnatal day 7 (PD7). The same protocol was employed to evaluate maternal behavior for filial generation 1 (F1) and filial generation 2 (F2) dams. Offspring development was evaluated for F1, F2, and F3 generations. Developmental landmarks and neurological reflexes were assessed from PD8 until complete development of the landmark or acquisition of the reflex.Results: Our results show that malnourished dams provide a lesser and more fragmented maternal care than their normally fed counterparts. This altered maternal behavior as well as the delay in the physical and neurological development observed in the offspring from malnourished mothers was transmitted up to two generations at least.Conclusion: These results highlight the harmful effects of protein malnutrition even for generations that are not directly exposed to this environmental adversity.

Abstract
Calorie restriction (CR) during sensitive perinatal periods has consistently been demonstrated to alter the development of a variety of physiological systems, which consequently affect behavior. This study compared the social behavior and sexual behavior of the adult male offspring of mothers administered a 25% CR at one of four times in the perinatal period: a brief period preconception, during gestation, during lactation, or a lifelong restriction (beginning at conception and continuing throughout life). Levels of serum testosterone were also determined in these animals. Social interaction increased in the gestation and lifelong CR groups. The lifelong group also exhibited more dominant type behaviors. CR during preconception and lactation resulted in offspring that displayed an enhanced and more efficient copulatory pattern compared to all other conditions. This was demonstrated by a reduced frequency of intromissions, shorter latency to ejaculation, and a greater frequency of ejaculations by the preconception and lactation group compared to some, if not all of the other CR groups and controls. Serum testosterone was significantly higher in the preconception group compared to controls. These findings indicate that CR during specific periods of development can differentially alter the social behavioral phenotype and hormone levels in adulthood.
