Instead, when injected in mice, tumors unable to cause BWL—such as the triple-negative breast cancer 4T1 [11]—neither MuRF1 nor apelin expression in muscles appeared altered (Figure 2G,H) as well as the expression of atrogin-1 and Musa1 (Supplementary Figure S1G,H). The gene discussed is FBXO32; the disease is triple-negative breast carcinoma.
