  • 功能：
    Cytokine that may play an important role during carcinogenesis and metanephric kidney organogenesis, as a BMP antagonist required for early limb outgrowth and patterning in maintaining the FGF4-SHH feedback loop. Down-regulates the BMP4 signaling in a dose-dependent manner. Antagonist of BMP2; inhibits BMP2-mediated differentiation of osteoblasts (in vitro). Acts as inhibitor of monocyte chemotaxis. Can inhibit the growth or viability of normal cells but not transformed cells when is overexpressed.

    13. GREM1 is frequently expressed by myofibroblasts in scars or in the stroma of basal cell carcinomas, suggesting that GREM1 expression can be a marker for activated myofibroblasts in the cancer stroma or in scar tissue. PMID: 28346486

PMID: 27428020
    16. Gremlin1 protein expression in colorectal cancer associates with low tumour stage and extended survival independently of tumour stage, suggesting that it represents a relevant prognostic indicator in colorectal cancer PMID: 27257976
    17. The results suggest that inhibition of BMP-2 by Gremlin-1 occurs by a mechanism that is distinct from other known inhibitors such as Noggin and Chordin and study propose a novel model of BMP-2-Gremlin-1 interaction yet not seen among any BMP antagonists, and cannot rule out that several different oligomeric states could be found, depending on the concentration of the two proteins. PMID: 27036124

    22. The critical element of the Gremlin-1 molecule for regulating MIF-induced chemotactic activity lies at the C-terminal region. A single amino acid exchange of an arginine to an alanine residue is sufficient to abolish the antagonistic effect of Gremlin-1 on MIF. The Gremlin-1 mutant R172A failed to reduce MIF-induced monocyte differentiation into macrophages. PMID: 26872252

    40. we show that epithelial expression of GREM1 also occurs in traditional serrated adenomas, sporadic premalignant lesions with a hitherto unknown pathogenesis, and these lesions can be considered the sporadic equivalents of HMPS polyps. PMID: 25419707
    41. Gremlin could participate in renal fibrosis by inducing EMT in tubular epithelial cells through activation of Smad pathway and induction of TGF-b PMID: 24949470
