Dietary supplements have improved the prevention of insulin resistance and metabolic diseases, which became a research hotspot in food science and nutrition. Obesity and insulin resistance, caused by a high-fat diet, eventually result in severe metabolic diseases, can be prevented with the dietary supplement D-chiro-inositol (DCI). In this work, we isolated mice primary hepatocytes with palmitic acid stimulation and DCI was applied to compare and contrast its effects of in primary hepatocyte biology. Before and after intervention with DCI, we used RNA-Seq technology to establish a primary hepatocyte transcriptome gene profile. We found that both PA and DCI cause a wide variation in gene expression. Particularly, we found that DCI plays critical role in this model by acting on glycolysis and gluconeogenesis. Overall, we generated extensive transcripts from primary hepatocytes and uncovered new functions and gene targets for DCI.
膳食补充剂改善了胰岛素抵抗和代谢性疾病的预防,这成为食品科学和营养领域的研究热点。高脂肪饮食引起的肥胖和胰岛素抵抗最终会导致严重的代谢性疾病,而膳食补充剂 D-手性肌醇(DCI)可以预防这种疾病。在这项工作中,我们用棕榈酸刺激分离了小鼠原代肝细胞,并应用 DCI 来比较和对比其在原代肝细胞生物学中的作用。在 DCI 干预前后,我们使用 RNA-Seq 技术建立了原代肝细胞转录组基因图谱。我们发现 PA 和 DCI 都会引起基因表达的广泛变化。特别是,我们发现 DCI 通过作用于糖酵解和糖异生在该模型中发挥关键作用。总的来说,我们从原代肝细胞中生成了大量的转录本,并揭示了 DCI 的新功能和基因靶点。
