["To determine whether treatment of rat dams with oleoyl-estrone (OE) has an effect on the offspring's long-term response to diet restriction during lactation.", 'Control, OE-treated, and diet-restricted dams were treated up to day 15 of lactation. Changes in food intake and body weight were recorded for dams and their pups. After weaning, pups received a 4-week standard diet followed by a 4-week period of high-fat diet. Lipid, protein, and energy content of pups plus energy intake and efficiency. Serum metabolites (glucose, urea, and cholesterol) and serum hormones (adiponectin, leptin, insulin, and sexual hormones).', 'Neither pups from dams in the OE-treated nor in the diet-restricted group showed significant changes in weight, though these two groups ingested 79% of food ingested by controls. At weaning, the pups from OE-treated rats were smaller than those of the control or diet-restricted groups. These pups maintained the differences in size and lipid content during the 4-week standard-diet period, whereas pups from diet-restricted dams showed a sharp decrease in their lipid content. During the 4 weeks of high-fat diet, the male offspring from OE-treated dams increased the difference in lipid content in relation to the pups from control dams whereas in females the differences decreased. Female offspring from diet-restricted dams showed the most marked changes in metabolite and hormone levels in relation to controls.'] Does maternal treatment with oleoyl-estrone induce resistance to lipid accrual in their descendants?
