Critical importance of the Notch1

TSG1, HGS, and STAM2 appear critical in the importance of the NOTCH1.

We have stressed the importance of the NOTCH in cancer and wanted to provide some of the proof for the supportive evidence found in the literature.  The Notch through its interaction with MAML1, easily affects EP300 leading to activation of TSG, a critical gene in the action of P53.  Indeed P53 acts by activating TSG which leads to an increasing inhibitory activity of p21 on CDKs, blocking as a result cell division and therefore proliferation.
Inhibition at the NOTCH will therefore remove breaks to cell division and will mark a significant tendency to cancer incurability!
And I wish things stop there, but they don't:
The Activation of TSG will disturb the resting HSG which bothers the Merlin and blocks NF2 leading to the loss of growth control by contact of surrounding cells, the cell losing control of its growth...Hyperplasia can easily ensue!
The HSG now excited, engages the STAM2 and 3 things:

1. Interaction with JAK1 leading to metastasis

" Expression of JAK1 in cancer cells enables individual cells to contract, potentially allowing them to escape their tumor and metastasize to other parts of the body (wikipedia)"
the involvement of JAK-1 multiply the worsening of the situation because it will excite: PTPN11

" PTPN11 is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation." 
and with the ELP gene, the process will affect the SMAD3 leading to loss of control of proliferation and normal ubiquitylation of inhibitory proteins.

2.S TAM2 will engage Cytokin Receptors  (Cullins)

3. STAM2 will engage the tract to E3.

But the engagement of the Notch does still not stop there...

the GSK3B comes into play! and ....
