Abstract:
FYN, one of the members of the Src family of kinases (SFKs), has been reported to be overexpressed in various types of cancers and correlated with cell motility and proliferation. However, the mechanism is still unclear. In the present study, we found that FYN was overexpressed in breast cancer and overexpression of FYN promoted cell proliferation, migration and invasion in the MCF10A cells, whereas depletion of FYN suppressed cell proliferation, migration and invasion in the MDA-MB-231 cells. Moreover, FYN upregulated the expression of mesenchymal markers and epithelial-mesenchymal transition (EMT)-related transcription factors, and downregulated the expression of epithelial markers, suggesting that FYN induces EMT in breast cancer cells. Furthermore, FYN was transcriptionally regulated by FOXO1 and mediated FGF2-induced EMT through both the PI3K/AKT and ERK/MAPK pathways.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
