Call it the cellular equivalent of big glasses, a funny nose and a fake mustache.
Bone marrow stem cells attracted to the site of a cancerous growth frequently take on the outward appearance of the malignant cells around them, University of Florida researchers report in a paper to be published in the August issue of Stem Cells.

A phase II clinical trial of an angiogenesis inhibitor to treat glioblastoma has shown promise in a majority of patients tested, say researchers at Massachusetts General Hospital and Harvard Medical School. But they also say that the novel imaging and biomarker studies they performed as treatment was underway have revealed why the treatment, AZD2171, ultimately failed, and what might improve the response.

A small molecule derived from the spacer domain of the tumor-suppressor gene Rb2/p130 has demonstrated the ability to inhibit tumor growth in vivo and could be developed into an anti-cancer therapeutic, according to researchers at Temple University's Sbarro Institute for Cancer Research and Molecular Medicine.

A new study suggests how a notorious cancer gene may contribute to tumor growth.
