From: The cell nuclei of skeletal muscle cells are transcriptionally active in hibernating edible dormice
Myonuclei from euthermic (a, e) and hibernating (b-d, f) edible dormice; LRWhite embedding, EDTA staining. a-d. Immunolabelling with anti-DNA/RNA hybrid molecule antibody: the signal occurs in both nucleoplasm, where it is mainly associated to PF (arrows), and in nucleolar DFC (arrowheads). The amorphous body (AB) is unlabelled. e, f. Immunolabelling with anti-phosphorylated polymerase II antibody: a specific signal is present over PF (thick arrows). Bars = 0.2 μm.
