Correction: Stable atrogin-1 (Fbxo32) and MuRF1 (Trim63) gene expression is involved in the protective mechanism in soleus muscle of hibernating Daurian ground squirrels (Spermophilus dauricus)

There was an error published in Biol. Open (2016) 5, 62-71 (doi:10.1242/bio.015776).

In Fig. 4, the Autumn-control image in panel B was erroneously a duplication of the Autumn-HU image in panel D.

Fig. 4.

(corrected). Effects of HU in different seasons on SOL ultrastructure in Daurian ground squirrels. Ultrastructure of longitudinal (A,C,E,G) and transverse (B,D,F,H) sections of soleus muscle in Autumn-control (A,B), Autumn-HU (C,D),Winter-control (E,F) and Winter-HU (G,H), showing several anomalies in the SOL ultrastructure of the two HU groups: disruptions of the sarcomeres with widening of the inter-fiber spaces (black arrows); irregular and discontinuous Z line (white arrows); hardly recognizable A and I bands and Z (black arrowheads); relative excess of actin filaments and decreases in amount of myosin filaments (white arrowheads); disruptions in the hexagonal arrangement (asterisks).

The corrected figure is shown below.
