Macrophage activation determines muscle wasting in pancreatic cancer.

ABSTRACT: The contribution of non-cancer tumoral microenvironment to cachexia is vastly unclear. Despite advances in understanding the signals involved in cancer cachexia progression, the exact time point of cachexia onset remains unpredictable. The transgenic Kras^LSL-G12D/+;Trp53^flox/flox;Pdx1-Cre (KP₂C) GEMM is a clinically relevant model, with the timing of cancer cachexia progression from the pre-cachectic, early-onset, to severe cachexia showed that the onset of cachexia was associated with differences in muscle wasting. The exact cell-of-origin in different types of non-cancer cells in the tumoral microenvironment and the circulating blood, which drives cachexia, remains unclear.
