A protein secreted by tumors, known as ADAMTSL4, plays a central role in cancer cachexia by locally activating the TGF-β signaling pathway in muscle and fat tissue. [^1]

Researchers at Helmholtz Munich, the Heidelberg Faculty of Medicine, the German Center for Diabetes Research, and the Technical University of Munich identified a previously unknown mechanism that drives cancer cachexia. [^2]

Dr. Juliano Machado, first author of the study and postdoc at the Institute for Diabetes and Cancer, said that switching off ADAMTSL4 production in tumor cells significantly reduced muscle and fat mass loss in mice. [^3]

The team found elevated ADAMTSL4 levels in the blood of several mouse models of cancer cachexia and in patients with colorectal and lung cancer. [^4]

Dr. Mauricio Berriel Diaz, research group leader at the Institute for Diabetes and Cancer (IDC) at Helmholtz Munich, stated that the team wanted to understand which signals from the tumor trigger the breakdown of muscle and fat tissue. [^5]
