To test this, we analyzed survivin expression by immunochemistry in ascites from 11 patients without obesity but with different tumors (stomach, serous ovarian carcinoma, ovarian clear cell, rectum, bile duct, colon and pleural mesothelioma) and from 5 patients without obesity and without tumors (cirrhosis, congestive heart failure and ovarian cystadenoma with mesothelial hyperplasia). Here, BIRC5 is linked to Obesity.
