Fig. 5. CAP350 does not affect RXR
or TR
subcellular localization. Representative images of NIH3T3 cells transfected with an expression vector for RXR
alone (A-C) or TR
alone (J-L) or cotransfected with expression vectors for RXR
and CAP350 (D-F) or TR
and CAP350 (M-O), and analyzed by indirect immunofluoresence microscopy with anti-RXR
antibody or anti-TR
antibody (green) and anti-c-Myc antibody (red) to detect tagged CAP350. The merged images indicate that CAP350 does not alter the subcellular localization of RXR
or TR
(F and O, respectively). Nuclei were detected by staining with Hoechst (B and K). (G-I) PPAR
ligand does not affect the subcellular relocalization of PPAR
in the presence of CAP350. NIH3T3 cells were transfected with expression vectors for PPAR
and CAP350 in the presence of the PPAR
ligand Panagonist B and subjected to immunostaining with anti-PPAR
antibody (green) and anti-c-Myc antibody (red) to detect tagged CAP350. The merged image (I) shows that ligand does not alter the colocalization of PPAR
and CAP350. Bars, 10 µm.
