ECM1 and neoplasm: The Ziegler mass spec study found that a large number of ECM proteins (BGN, CD44, CD109, DAG1, DCN, ECM1, EFEMP1, FMOD, IGFBP4, IGFBP7, LTBP1, L1CAM, LGALS1, LGALS3BP, LOXL2, LTBP1, NRCAM, P4HB, PLOD1, PPIB, TGFBI, THBS1, TLN1, and TNC) were more highly expressed in TNBC CM on average compared to in MCF-7 CM, although DCN and TGFBI were also more highly expressed in non-tumor MCF-10A CM [11].
