Cover photograph (Copyright © 2007, American Society for Microbiology. All Rights Reserved.): Subcellular localization of FATP1 in skeletal muscle. Soleus muscle from mice fasted overnight after intraperitoneal injection of insulin is shown. Muscle strips were fixed in 2\% paraformaldehyde, thick sectioned, and stained with antibodies against caveolin 3 (blue), FATP1 (red), and CD36 (green). Nuclei were stained with DAPI (4′,6′-diamidino-2-phenylindole) and are pseudocolored in turquoise. Three-dimensional reconstructions of confocal image stacks and overlay of the different channels were performed using the Volocity program. Caveolin 3 served as a plasma membrane marker illustrating that after insulin stimulation FATP1 is predominantly localized to the sarcolemma.
