Serum Amyloid A Proteins and Their Impact on Metastasis and Immune Biology in Cancer

Cancers (Basel). 2021 Jun 25;13(13):3179. doi: 10.3390/cancers13133179.


Cancer triggers the systemic release of inflammatory molecules that support cancer cell metastasis and immune evasion. Notably, this biology shows striking similarity to an acute phase response that is coordinated by the liver. Consistent with this, a role for the liver in defining cancer biology is becoming increasingly appreciated. Understanding the mechanisms that link acute phase biology to metastasis and immune evasion in cancer may reveal vulnerable pathways and novel therapeutic targets. Herein, we discuss a link between acute phase biology and cancer with a focus on serum amyloid A proteins and their involvement in regulating the metastatic cascade and cancer immunobiology.

Keywords: acute phase response; cancer; immune cells; immunotherapy; liver; metastasis; serum amyloid A.
