e_re22( EMT ):
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.

Keratin-14, 18, 19, Vimentin are putative direct HIF1 target genes
Genes induced by HIF-1 in cancer cells include KRT-14, 18, 19, Vimentin, VEGF
HIF1 target genes include TGFB3, VEGF
VEGF is induced by hypoxia in a HIF1-dependent way
Prokinecticin 1 (EG-VEGF) is induced by hypoxia through a potential HIF1-dependent mechanism indicates that this gene is in the same homeostatic cascade as VEGF, Flt1 and erythropoietinPMID:17987801 PMID:16716598
