Abstract:

This study determined the effects of a high-fat diet and plasminogen activator inhibitor-1 deficiency (Pai1(-/-)) on the bone structure in male C57BL/6 mice bearing Lewis lung carcinoma (LLC) in lungs. Significant reduction in bone volume fraction (BV/TV), trabecular number (Tb.N) and bone mineral density (BMD) in femurs and vertebrae were found in LLC-bearing mice compared to non-tumor-bearing mice. In LLC-bearing mice, the high-fat diet compared to the AIN93G control diet significantly reduced BV/TV, Tb.N and BMD in femurs and BV/TV in vertebrae. The high-fat diet significantly reduced BMD in vertebrae in wild-type mice but not in Pai1(-/-) mice. Compared to wild-type mice, PAI1 deficiency significantly increased BV/TV and Tb.N in femurs. The plasma concentration of osteocalcin was significantly lower and that of tartrate-resistant acid phosphatase 5b (TRAP5b) was significantly higher in LLC-bearing mice. The high-fat diet significantly reduced plasma osteocalcin and increased TRAP5b. Deficiency in PAI1 prevented the high-fat diet-induced increases in plasma TRAP5b. These findings demonstrate that a high-fat diet enhances, whereas PAI1 deficiency, attenuates metastasis-associated bone loss, indicating that a high-fat diet and PAI1 contribute to metastasis-associated bone deterioration.
