Figure 1.
Cancer cachexia exacerbates atrophy in denervated mouse skeletal muscles. Photographs of anesthetized control (CNT) and cancer cachexia (CCX) mice (A). Images after mouse laparotomy in CNT (B) and CCX mice (C). Note that CCX mice showed extensive intraperitoneal tumor growth (dotted circle). The body (D) and heart (E) weight in each group. Bars show the mean and SEM results from 6 to 7 mice per group. §P < 0.05 vs. CNT. The muscle wet weight of fast-twitch gastrocnemius (F) and plantaris muscles (G) and slow-twitch soleus muscles (H) from CNT and CCX mice, with or without denervation (DEN). Bars show the mean and SEM results from 6 to 7 muscles per group. Statistical significance was set at P < 0.05: main effect of aCCX and bDEN; cinteraction of CCX and DEN; difference vs. *CNT without DEN, #CNT with DEN, and †CCX without DEN.
