High-mobility group box 1 (HMGB1) protein acts as a DNA chaperone for nuclear
homeostasis. It translocates into the cytosol and is secreted into extracellular
spaces, triggering proinflammatory cytokines and acting as a mediator in
fibrosis. We determined whether HMGB1 plays a role in normal dermal fibrosis and
keloid, and is involved with transforming growth factor ?. We investigated the
translocation and active release of HMGB1 from normal dermal fibroblasts under
lipopolysaccharide stimuli, and the redistribution of nuclear HMGB1 into the
cytoplasm of keloid fibroblasts. HMGB1 and its effector toll-like receptors and
receptors for advanced glycation end product proteins are actively expressed in
keloid tissues. Exogenous HMGB1 can induce the proliferation of human dermal
fibroblasts, and could act as a profibrogenic molecule to produce collagen,
decrease MMP-1, and increase TIMP-1 mRNA expression. Moreover, administration of
HMGB1 increased the expression level of TGF-?1 and internal signaling molecules,
such as Smad 2 and 3, phosphorylated Smad 2/3 complex, Erk 1/2, Akt, and NF-?B.
Collectively, we demonstrate that HMGB1 treatment increases the expression level
of collagen types I and III, elastin, and fibronectin in dermal spheroid
cultures, thus making HMGB1 a promising therapeutic target for treatment of
profibrogenic diseases.
