Bottom Line: Blood and carcass as well as retroperitoneal, epididymal, and subcutaneous white adipose tissues were collected.Food intake and body weight were lower in TC and TT, and metabolic efficiency was reduced in TT.Ingestion of hydrogenated vegetable fat by the mother during gestation and lactation could promote deleterious consequences, even after the withdrawal of the causal factor.

ABSTRACT
We examine whether feeding pregnant and lactating rats hydrogenated fats rich in trans fatty acids modifies the plasma lipid profiles and the expression of adipokines involved with insulin resistance and cardiovascular disease in their 90-day-old offspring. Pregnant and lactating Wistar rats were fed with either a control diet (C group) or one enriched with hydrogenated vegetable fat (T group). Upon weaning, the male pups were sorted into four groups: CC, mothers were receiving C and pups were kept on C; CT, mothers were receiving C and pups were fed with T; TT, mothers were receiving T and pups were kept on T; TC, mothers were receiving T and pups were fed with C. Pups' food intake and body weight were quantified weekly and the pups were killed at day 90 of life by decapitation. Blood and carcass as well as retroperitoneal, epididymal, and subcutaneous white adipose tissues were collected. Food intake and body weight were lower in TC and TT, and metabolic efficiency was reduced in TT. Offspring of TT and TC rats had increased white adipose tissue PAI-1 gene expression. Insulin receptor was higher in TT than other groups. Ingestion of hydrogenated vegetable fat by the mother during gestation and lactation could promote deleterious consequences, even after the withdrawal of the causal factor.

Adiponectin mRNA quantification in retroperitoneal white adipose tissue. CC, mothers fed C diet and offspring fed C diet; CT, mothers fed C diet and offspring fed T diet; TT, mothers fed T diet and offspring fed T diet; TC, mothers fed T diet and offspring fed C diet. Data are means ± SE of six determinations per group. Results are expressed in arbitrary units, stipulating 100 as the control value. p < 0.05.

Mentions: Adiponectin gene expression in RET of the CT group was higher than in the CC group (Figure 3). On the other hand, a decrease was observed in PAI-1 gene expression in the CT group (Fig 4A) compared with the other groups.
