Subcellular localization of lnc-ORA in proliferating and differentiating myoblasts.A, subcellular localization of lnc-ORA by FISH in myoblasts. Special FISH probes against lnc-ORA, U6, and 18S were modified by Cy3 in red. 18S is a cytoplasmic marker, and U6 is a nuclear marker. The nucleus was stained by DAPI in blue. The scale bar represents 50 μm. B, subcellular localization of lnc-ORA by FISH in myotubes. Special FISH probes against lnc-ORA, U6, and 18S were modified by Cy3 in red. 18S is a cytoplasmic marker, and U6 is a nuclear marker. The nucleus was stained by DAPI in blue. The scale bar represents 50 μm. DAPI, 4′,6-diamidino-2-phenylindole; lnc, long noncoding; lnc-ORA, obesity-related lncRNA.
