Figure 4. mRNA expression of PTRF in skeletal muscle, and quantitative RT-PCR of mRNAs for caveolins.
(A) RT-PCR analysis revealed a single band for PTRF mRNA (arrow) in a control subject, but no detectable product was seen in P1–P5. M, marker. (B–D) By quantitative RT-PCR, mRNA for CAV1, CAV2, and CAV3 normalized with GAPDH expression was not decreased in P1–P5.
