Figure 1: Fructose transiently induces genes involved in lipogenesis during adipocyte maturation. Expression of important lipogenic genes is shown in the presence (red squares) and in the absence of fructose (blue diamonds). -axis: relative expression compared to expression of actin mRNA. FASN and GPAM are strongly induced between day ten and sixteen. The insulin-dependent glucose transporter GLUT4 follows the same course. No significant differences are seen for leptin expression. Each symbol depicts one qPCR measurement per dish in a representative experiment.
