Fig. 4. Expression of PPAR
and adipsin transcripts in 3T3-L1 transfectants.
Total RNA isolated on days 0, 1, 2, 3, 5 and 7 after adipogenic induction was
analyzed by semi-quantitative RT-PCR as described in Materials and Methods.
Results are representative of five independent experiments on three individual
clones of each transfectant type. The levels of PPAR
and adipsin
transcripts markedly increased in control cells during differentiation. In
1-PDX cells, the increase was significantly lower for adipsin and not
observed for PPAR
.
