PNPLA2 and injury: To further evaluate the possible impact of Foxn1/Hif-1α on dWAT functional reconstruction after skin injury, we analyzed the expression of genes involved in de novo lipogenesis (Srebp1c—sterol regulatory element-binding protein 1c, Fasn—fatty acid synthase and Glut1 and Glut4—transmembrane glucose transporters; Figure 7A–D) and lipolysis (Atgl—adipose triglyceride lipase; Figure 7E).
