Artificial selection for increased maternal defense behavior in mice.
Maternal aggression is directed towards intruders by lactating females and is critical for defense of offspring. Within-family selection for increased maternal defense in outbred house mice (Mus domesticus; Hsd:ICR strain) was applied to one selected (S) line, using total duration of attacks in a 3-min test as the selection criterion. One control (C) line was maintained and both lines were prop...
متن کاملMaternal defense: breast feeding increases aggression by reducing stress.
Mothers in numerous species exhibit heightened aggression in defense of their young. This shift typically coincides with the duration of lactation in nonhuman mammals, which suggests that human mothers may display similarly accentuated aggressiveness while breast feeding. Here we report the first behavioral evidence for heightened aggression in lactating humans. Breast-feeding mothers inflicted...
متن کاملCatalase Prevents Maternal Diabetes–Induced Perinatal Programming via the Nrf2–HO-1 Defense System
We investigated whether overexpression of catalase (CAT) in renal proximal tubular cells (RPTCs) could prevent the programming of hypertension and kidney disease in the offspring of dams with maternal diabetes. Male offspring of nondiabetic and diabetic dams from two transgenic (Tg) lines (Hoxb7-green fluorescent protein [GFP]-Tg [controls] and Hoxb7/CAT-GFP-Tg, which overexpress CAT in RPTCs) ...
متن کاملInvasive Egg Predators and Food Availability Interactively Affect Maternal Investment in Egg Chemical Defense
Invasive species commonly predate the offspring of native species and eggs are the life stage most vulnerable to this predation. In many species with no maternal care, females can alter the phenotype of eggs to protect them, for instance through chemical defense. In ladybirds egg alkaloids deter predators, including invasive predatory species of ladybirds, but conversely may attract cannibals w...
متن کاملEarly disruption of maternal-zygotic interaction and activation of defense-like responses in Arabidopsis interspecific crosses.
Seed death resulting from hybridization between Arabidopsis thaliana and Arabidopsis arenosa has complex genetic determination and involves deregulation 5 to 8 d after pollination (DAP) of agamous-like genes and retroelements. To identify causal mechanisms, we compared transcriptomes of compatible and incompatible hybrids and parents at 3 DAP. Hybrids misexpressed endosperm and seed coat regula...
