Allergic inflammation has been known to enhance the metastatic potential of tumor
cells. The role of histone deacetylase-3 (HDAC3) in allergic skin inflammation
was reported. We investigated HDAC3 involvement in the allergic
inflammation-promotion of metastatic potential of tumor cells. Passive systemic
anaphylaxis (PSA) induced HDAC3 expression and Fc?RI signaling in BALB/c mice.
PSA enhanced the tumorigenic and metastatic potential of mouse melanoma cells in
HDAC3- and monocyte chemoattractant protein 1-(MCP1)-dependent manner. The
PSA-mediated enhancement of metastatic potential involved the induction of HDAC3,
MCP1, and CD11b (a macrophage marker) expression in the lung tumor tissues. We
examined an interaction between anaphylaxis and tumor growth and metastasis at
the molecular level. Conditioned medium from antigen-stimulated bone
marrow-derived mouse mast cell cultures induced the expression of HDAC3, MCP1,
and CCR2, a receptor for MCP1, in B16F1 mouse melanoma cells and enhanced
migration and invasion potential of B16F1 cells. The conditioned medium from
B16F10 cultures induced the activation of Fc?RI signaling in lung mast cells in
an HDAC3-dependent manner. Fc?RI signaling was observed in lung tumors derived
from B16F10 cells. Target scan analysis predicted HDAC3 to be as a target of
miR-384, and miR-384 and HDAC3 were found to form a feedback regulatory loop.
miR-384, which is decreased by PSA, negatively regulated HDAC3 expression,
allergic inflammation, and the positive feedback regulatory loop between
anaphylaxis and tumor metastasis. We show the miR-384/HDAC3 feedback loop to be a
novel regulator of the positive feedback relationship between anaphylaxis and
tumor metastasis.
