Figure 1.
The mRNA levels of Retn, Tnfα, and Ccl2 in 3T3-L1 cells (preadipocyte and adipocyte) and SW872 cells treated by normoxia or IH for 24 h. The levels of the adipokine mRNAs were measured by real-time RT-PCR using Rig/RpS15 (in mouse) and β-actin (in human) as an endogenous control. Data is expressed as mean ± SE for each group (n = 4). The statistical analyses were performed using Student’s t-test.
