Smad proteins act as Transcriptional Activators via functional interactions with the Transcription factor Sp1

Myc represses differentiation-induced p21 expression via Miz-1-dependent interaction with the p21 core promoter
Myc binds the p21 core promoter in vitro through interaction with Miz-1
Myc and Miz-1 interact with the p21 promoter in vivo
PMID:15155580
Snail regulates cell-cycle progression and survival:
Snail regulates components of the early to late G1 transition and the G1/S checkpoint.
Snail represses Cyclin D2 transcription and increases p21/Cip1 transcription.

Myc: an ubiquitous mediator of cell growth and proliferation
Myc can both activate and repress transcription, depending on the nature of associated factors
TGFB downregulates Myc to cause cell cycle arrest.
TGFB activates p15INK4B and/or p21CIP1 (inhibitor of CDKs) ==> CDK inhibition by TGFB
TGFB downregulates cdc25A (a phosphatase, activator of CDKs) ==> CDK inhibition by TGFB

MYC induces DNA damage throuh an increase in ROS production, innapropriate DNA synthesis and abrogation of DNA repair

MYC in complex with CDK2 alone inhibit senescence through the inhibition of p16 and p21 expression as well as TERT and BMI1 expression increase. MYC in complex with CDK2 and p27KIP1 induces senescence through the expression increase of p16 and p21 as well as TERT and BMI1 expression decrease. WRN inhibit MYC induced senescence.
