Shao et al presented their findings at the 100th AACR meeting in Denver, Co. The team identified an angiogenic role for YKL-40 in tumor growth and development. Ectopic expression of YKL-40 in MDA-MB-231 breast cancer cells and HCT-116 colon cancer cells led to an extensive angiogenic phenotype of xenografted tumors in SCID/Beige mice and these tumors were 4-8 fold larger than the tumors developed from control cells.
