Moreover, we also have found that CBG inhibits the fibrotic muscular remodeling during the obesity state, which was revealed by a significant upregulation of secreted matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9) as well as collagen type 1, and type 3 (COL-1A1 and COL-3A1) expression, which contributes to the regulation of extracellular matrix turnover and probably may increase the regenerative capacity of the skeletal muscles. This evidence concerns the gene COL3A1 and obesity due to melanocortin 4 receptor deficiency.
