 A corrigendum on Lacticaseibacillus casei CNCM I-5663 supplementation maintained muscle mass in a model of frail rodents by Giron, M., Thomas, M., Jarzaguet, M., Mayeur, C., Ferrere, G., Noordine, M.-L., Bornes, S., Dardevet, D., Chassard, C., and Savary-Auzeloux, I.

In the published article, there was an error in the legend for Figure 6A as published. The title on Y-axis is “Protein content in hindlimb muscle (mg/g).” The corrected legend appears below.

Levels of protein, insulin pathway mediators, and proteolysis-related gene expression in the muscles of 18-month-old rats fed an ad libitum (AL) diet or a food-restricted (R) diet over a one-month period; one food-restricted group received a probiotic supplement – strain 63 (R+63). (A) Protein levels in hindlimb muscles (gastrocnemius, soleus, tibialis anterior, and extensor digitorum longus). (B) Levels of proteins involved in the AKT/mTOR/S6K pathway: ratio of phosphorylated proteins, p-S6 (Ser235/236), and p-eIF2α (Ser51), to total proteins, S6 and eIF2α. (C) Expression levels of muscle proteolysis genes, namely those related to the regulation of the ubiquitin-proteasome-dependent pathway (Atrogin-1 and MuRF-1) and autophagy pathway (Lc3b, ATG16L, and Cathepsin L). Values are means ± SEM. Differences in letters indicate a significant difference between groups (Kruskal–Wallis test and Dunn's post hoc test, p ≤ 0.05, n = 61 rats).

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
