In NMuMG cells treated with TGFB1 Snail1 RNA and protein are induced 1 h after addition of the cytokine preceding Zeb1 up-regulation that requires 6???8 h.
Zeb1 gene expression is caused by increased RNA levels but also by enhanced protein stability and is markedly dependent on Snail1 because depletion of this protein prevents Zeb1 protein and RNA up-regulation

TGFB can activate both SNAI1 and SNAI2 and thus promote EMT via both SMAD-dependent and -independent pathways

Activation of Slug (SNAI2) by two mechanisms:
-transcriptional activation of Slug by the CTNNB1and TCF/LEF complex
-activation of the ERK pathway.
When adherens junctions are established in dense cultures, ErbB1/2 and the ERK pathway become inactive, CTNNB1 is localized at adherens junctions, Slug expression is reduced, and E-cadherin transcription is induced.
Antibody-mediated disruption of adherens junctions led to nuclear CTNNB1 localization and enhanced beta-catenin signaling, induction of Slug and inhibition of E-cadherin expression.

Snail1 induces Snail2 transcription.
Snail is able to induce the expression of Slug and all other neural crest markers (Zic5, FoxD3, Twist and Ets1)

Snail2 activates the Snail2 promoter

Twist1 binds to an E-box on the proximate Snail2 promoter to induce its transcription.

HMGA2 directly binds to the SNAIL1 promoter and acts as a transcriptional regulator of SNAIL1 expression.
HMGA2 cooperates with SMAD3 and SMAD4 to execute a dramatic super-induction of the SNAIL1 promoter.
Same results were obtained with SNAI2, ZEB1, ZEB2 and TWIST1
HMGA2 cooperates with TGFB1 signaling to represse ID2 transcriptomal expression
