The aim of this study was to analyze possible alterations (morphological and inflammatory) in the ocular cells of fetuses from mothers with insulin resistance exposed to saturated fatty acids through the period of pregnancy.
Wistar female rats were induced to develop insulin resistance before pregnancy. Fetuses' skulls were collected on the 20th day of intrauterine life. The rats were separated on the first day of management into two groups according to the diet applied: control group (C): diet containing soybean oil as a source of fat; and saturated fatty acid group (S): diet containing butter as a source of fat.
Histological and immunohistochemical analyses have been conducted. The immunohistochemical analyses of interleukin 6, suppressor of cytokine signaling, 3 and signal transducer and activator of transcription 3 did not demonstrate alterations in the expression of proteins in the fetuses of mothers fed with a saturated fatty diet. Moreover, no histopathological changes were noticed between groups.
The saturated fatty diet does not induce tissue changes or activate the Janus kinase/signal transducer and activator of transcription signaling pathway during eye development in the fetuses of mothers with insulin resistance.
本研究旨在分析孕期暴露于饱和脂肪酸的胰岛素抵抗母亲所生胎儿眼部细胞可能发生的改变(形态学和炎症方面)。
在怀孕前诱导Wistar雌性大鼠产生胰岛素抵抗。在子宫内生活的第20天收集胎儿的颅骨。在管理的第一天,根据所应用的饮食将大鼠分为两组:对照组(C):以大豆油为脂肪来源的饮食;饱和脂肪酸组(S):以黄油为脂肪来源的饮食。
进行了组织学和免疫组织化学分析。白细胞介素6、细胞因子信号转导抑制因子3和信号转导及转录激活因子3的免疫组织化学分析未显示喂食饱和脂肪饮食的母亲所生胎儿中蛋白质表达有改变。此外,两组之间未观察到组织病理学变化。
饱和脂肪饮食不会在胰岛素抵抗母亲所生胎儿的眼睛发育过程中诱导组织变化或激活 Janus激酶/信号转导及转录激活因子信号通路。
