Abstract

The transcriptional coactivator with PDZ-binding motif (TAZ) functions as a downstream regulatory target in the Hippo signaling pathway that plays various roles. We previously developed a cell-based assay and identified the TAZ activator IBS008738 as a potential therapeutic target for glucocorticoid-induced atrophy. To further explore the application of IBS008738 in various muscle-related diseases, we examined the function of IBS008738 in inflammatory cytokine-mediated mouse muscle responses after traumatic brain injury (TBI). Preliminary screening suggested that IBS008738 treatments increased the levels of IL-10 in C2C12 cells. In TBI and sham control mice, we compared the effect of IBS008738 treatments on TNF α, IL-6, and IL-10 mRNA levels, muscle morphologic changes, and macrophage phenotype changes. Our findings support that the TAZ activator IBS008738 decreases muscle wasting by upregulating IL-10 and inhibiting TNF α and IL-6, and this process is implemented by changing the macrophage phenotypes. These results indicate a new mechanism of the TAZ activator as a potential therapy for atrophy.
