Thirty-two genes (ADAM12, AEBP1, ASPN, ATXN10, BGN, COL10A1, COL1A1, COL5A2, COL6A2, COL8A2, COMP, CTSK, DCN, DPYL3, EMILIN1, FAP, FBLN1, FBN1, GLT8D2, ISLR, ITGBL1, LOXL1, LUM, MFAP5, MMP2, MXRA5, NID2, OLFML2B, RNF144A, SPARC, SPON1, and VCAN) were consistently coexpressed with THBS2 in breast cancer (S1C Fig). The gene discussed is CTSK; the disease is breast carcinoma.
