miR-221-5p is upregulated in CAFS and , miR-141, miR-200b, miR-101-3p are downregulated
TGF-??, IL-6 and RPS6KB1 are predicted as targets for miR-200b/c, IL-6, GRB2 are predicted as targets for miR-141

miR-200b targets Ets-1 and is down-regulated by Hypoxia to induce Angiogenic response of Endothelial cells
Overexpression of Est-1 reverses the phenotypic changes caused by miR-200b, supporting that miR-200b inhibits the angiogenic response via silencing of Est-1

The MIR200 family comprises 5 members (MIR200A, B, C, MIR141 and MIR429).
These 5 members are clustered and expressed as 2 separate polycistronic pri-miRNA transcripts, miR200B-200A-429 and miR200C-141.
These 2 transcripts are located on human chromosomes 1 and 12, respectively.

The gene expressions of MMP-1, MMP-3, and MMP-9 and gelatinolytic activity of MMP-9 were significantly increased in high ETS-1 expression cells.
Low ETS-1 expression cells could not spread on a vitronectin substratum, and the phosphorylation of focal adhesion kinase was markedly impaired because of the reduced expression of integrin b3

TCF8 (ZEB1) regulates cell invasion and migration via MMP1 expression.
TCF8 is likely to be dispensable for endothelial cell motility.
One possible mechanism underlying the increased invasiveness and migration might be the up-regulated digestion of ECMs via TCF8-mediated transcriptional regulation of the gene encoding MMP1.
MMP1 induction during tube formation was significantly enhanced in Matrigel when TCF8 was silenced

MiR-200b Regulates Ets-1-associated Genes
Suppression of endogenous miR-200b induced MMP-1 and VEGFR2 expressions
Overexpression of Ets-1 did not completely reverse miR- 200b-associated MMP-1 and VEGFR2 down-regulation.
It indicates that miR-200b, apart from targeting Ets-1, might silence other target proteins involved in transcription of the indicated genes.

Our results indicate that MT1-MMP is a direct down-stream target in the Wnt signaling pathway, and that one of the ways accumulated beta-catenin contributes to colorectal carcinogenesis is by transactivating this gene.
MT1-MMP is one target gene of Lef-1/Tcf-4 (Takahashi et al, 2002)
