Principal component analysis somparing the before treatment proteins (green circles) with after treatment proteins in the methylene blue group (blue circles) and control group (red circles).

Notes: There is some clustering observed before and after treatment. Fourteen proteins that contributed to the PCA were selected of 87 proteins (prolactin, TGF-α, TNF-RI, growth hormone, kallikrein-6, GM-CSF, CD30-L, thrombopoietin, prostasin, MMP-3, CXCL-11, EMMPRIN, HE4, and IFN-γ). The significance level was P=0.4.

Abbreviations: PCA, principal component analysis. TGF, transforming growth factor; TNF, tumor necrosis factor; GM-CSF, granulocyte macrophage colony-stimulating factor; MMP, matrix metalloproteinase; CXCL, (C-X-C) motif ligand; IFN, interferon.
