This result points to the existence of a tumor progression barrier different to p53.
However, no clear cut results were proposed ascertaining the existence of a molecular progression scheme between early carcinoma (stage 1), invasive (stage 2 and 3) and metastatic (stage 4) CRC.
However, one valid mathematical possibility is that the most important "hallmark of cancer", a unifying principle above all, is the existence of a measurable gradual "progression" from a well-differentiated gene expression profile (corresponding to a healthy tissue).
The vast majority of SMN1-deleted SMA patients carrying two SMN2 copies suffer from type I or II SMA, while only few patients (∼2%) develop a mild (type III SMA) phenotype (9), suggesting the existence of a yet unknown factor counteracting disease progression.
However, a relevant fraction of shared mutations significantly shifted their cancer cell fraction (CCF), while others were lost or acquired, suggesting the existence of a dynamic competition between subclones during disease progression.
Numerous in vivo studies in animals suggest the existence of a vicious cycle in the pathogenesis and progression of an osteolytic metastasis [ 4, 26, 27].
On the other hand, PI3K/AKT antagonizes TGFbeta-induced cytostatic responses and causes the shift in TGFbeta/SMAD signaling to its tumor-promoting mode during malignant tumor progression, thus indicating the existence of a signaling interplay between TGFbeta and PI3K/AKT pathways.
While CIN can act as a driver of cancer genome evolution and tumor progression, recent findings point to the existence of a threshold level beyond which CIN becomes a barrier to tumor growth, and therefore, it can be exploited therapeutically.

An increasing body of evidence supports the existence of a strong link between inflammation, endothelial dysfunction, and the onset and progression of atherosclerosis.
