Figure 9. Proposed mechanism of IS-induced muscle atrophy.

Figure 9

IS accumulates in muscle cells via Oat where IS activates NADPH oxidase and the AHR pathway to cause increased ROS production. The enhanced ROS production, in turn, triggers inflammatory cytokines (TNF-α, IL-6 and TGF-β1) induce myostatin and atrogin-1 expression that are involved in muscle wasting.
