Role of S100A7 in regulating inflammatory pathways during mammary tumorigenesis

Psoriasin (S100A7) has been shown to be highly expressed in invasive estrogen receptor negative breast cancers. Expression of S100A7 in human breast tumors represents a poor prognostic marker and correlates with lymphocyte infiltration in high-grade morphology. Recent studies have shown that S100A7 downregulation in ER- cells lines inhibits tumor growth in in vivo mouse model systems. However, not much is known about its mechanisms in regulating breast cancers.
