Abstract

Figure S3. Deterioration of physical condition in MDATO/OSM tumor-bearing mice treated with TET. a MDATO/OSM tumor-bearing mice treated with tetracycline (+TET) lost, on average, 11.4% of their body weight during TET treatment, compared with −TET mice, which gained an average of 5.5% of their body weight over the same period. b Representative image of mice with MDATO/OSM tumors +TET shows prominent spinal column, muscle wasting, and lack of visible adipose tissue. c Gross morphology of normal (left) and abnormal kidneys (right). Normal kidneys have a distinct border between the medulla and the cortex, with the cortex shown in a darker pink/red color and the medulla shown in a lighter pink color. This indicates that normal blood perfusion was taking place. Abnormal kidneys were either both pale and hypoperfused (middle) or damaged (right), with no clear distinction between the cortex and the medulla. d One hundred percent of mice in the +TET group have abnormal kidney morphologies, whereas only 25% of the mice in the −TET group have abnormal kidneys. **p < 0.01 by Fisher’s exact test. e Sera from mice with abnormal kidneys have a statistically significant higher level of OSM than sera from mice with normal kidneys. Data are expressed as mean ± SEM. *p < 0.05, **p < 0.01, and ***p < 0.001 by two-tailed Student’s t test. (ZIP 135 kb
