Abstract

Several studies have shown that cancer cells can be "phenotypically reversed", thus achieving a "tumor reversion", by losing malignant hallmarks as migrating and invasive capabilities. These findings suggest that genome activity can switch to assume a different functional configuration, i.e. a different Gene Regulatory Network pattern. Indeed, once "destabilized", cancer cells enter into a critical transition phase that can be adequately "oriented" by yet unidentified morphogenetic factors - acting on both cells and their microenvironment - that trigger an orchestrated array of structural and epigenetic changes. Such process can bypass genetic abnormalities, through rerouting cells toward a benign phenotype. Oocytes and embryonic tissues, obtained by animals and humans, display such "reprogramming" capability, as a number of yet scarcely identified embryo-derived factors can revert the malignant phenotype of several types of tumors. Mechanisms involved in the reversion process include the modification of cell-microenvironment cross talk (mostly through cytoskeleton reshaping), chromatin opening, demethylation, and epigenetic changes, modulation of biochemical pathways, comprising TCTP-p53, PI3K-AKT, FGF, Wnt, and TGF-8-dependent cascades. Results herein discussed promise to open new perspectives not only in the comprehension of cancer biology but also toward different therapeutic options, as suggested by a few preliminary clinical studies.
