Abstract Metabolism homeostasis plays an important role in progenitor‐cell differentiation to adipocytes, but less is known about the whole transcriptional profiling of cellular metabolism during adipogenesis. We got the first insight into the whole transcriptional profiling of cellular metabolism during adipogenesis from human mesenchymal stem cells (hMSCs) by the RNA‐Seq technique. There were 1,998, 2,629, 3,112, and 3,054 differentially expressed genes (DEGs) at Days 7, 14, 21, and 28, respectively, during adipogenesis. The most enriched phosphatidylinositol 3′ kinase–serine/threonine kinase (PI3K‐Akt) signaling pathway stimulated and directly regulated cellular metabolism by priming glucose aerobic glycolysis, arginine and proline metabolism, glutathione metabolism, and arachidonic acid metabolism during adipogenesis, targeting the potential key genes, such as fatty acid synthase (FABP4), phosphoenolpyruvate carboxykinase 1 (PKC1), stearoyl‐CoA desaturase (SCD), and solute carrier family 2 member 1 of Gluts (SLC2A1). And it confirmed PCK1 as the key player for cellular metabolism by small interfering RNA. A comprehensive understanding of cellular metabolism and its regulatory axis of the signaling pathway during adipogenesis would reveal new study and therapy targets for fat metabolism disorders.
