Heredity, nutrition, and craniofacial differentiation in weanling rats: A multivariate analysis

Abstract: The effects of paternal heredity, congenital variation, and preweaning nutrition on craniofacial growth were studied on weanling Wistar (W), Holtzman (H), and their reciprocal crosses, W/H and H/W, male rats. Between-group Mahalanobis D distances were calculated from the measurements made on lateral and vertical X-rays. Preweaning nutrition evoked the largest cranial differences, and paternal heredity the lowest; the effect of congenital variation was intermediate between these extremes. It is concluded that "… Show more

“…In order to achieve this goal, mouse embryos were exposed to maternal undernutrition, an environmentally induced perturbation with well documented effects on cranial growth (Pucciarelli and Goya, 1983;Pucciarelli and Oyhenart, 1987;Pucciarelli, 1991;Oyhenart et al, 1994;Cesani et al, 2006;Gonzalez et al, 2011a). Particularly, we analyze brain and skull phenotypes in mouse fetuses at E18.5 from an experimental model of maternal undernutrition to assess: a) the association between skull shape and brain size; b) coordinated shape variation between the skull and the brain as well as the allometric effect on their covariation; and c) coordinated shape changes between the neurocranium and the face, and the allometric effect on their covariation.…”

“…Por otra parte, Pucciarelli conjuntamente con otros integrantes de su equipo de investigación, continuaron empleando rasgos continuos con el objetivo de determinar: (a) la influencia de la nutrición materna sobre el crecimiento y la morfología de la descendencia considerando los períodos de gestación y lactancia (Pucciarelli y Oyhenart, 1987a, b;Oyhenart et al, 1994Oyhenart et al, , 1996, (b) la expresión del dimorfismo sexual y su manifestación cronológica en condiciones control (nutrición normal) y experimental (desnutrición proteico-calórica) (Oyhenart, 1988;Oyhenart et al, 2003a) y (c) los efectos de la hormona de crecimiento y de los esteroides gonadales sobre la recuperación del crecimiento y el patrón de dimorfismo sexual (Oyhenart y Pucciarelli, 1991, 1992Orden, 1997;Orden et al, 1998;Oyhenart et al, 2003b). Esta línea de investigación fue continuada por el equipo integrado por Fabián Quintero, Luis Guimarey, María Cecilia Fucini y Evelia Oyhenart.…”

“…Estos criterios han orientado numerosos estudios experimentales sobre el crecimiento craneofacial (Du Brul, 1965;Pucciarelli, 1981;Dahinten y Pucciarelli, 1986, Oyhenart, 1988Dressino, 1991, Oyhenart et al, 1994, Orden, 1997Orden et al, 1998). La mayoría de estos trabajos buscan explicar las modificaciones craneofaciales como producto adaptativo a demandas funcionales frente a determinados tipos de estreses, tales como el nutricional.…”
