Abstract: Cancer cell biology takes advantage of identifying diverse cellular signaling pathways that are disrupted
in cancer. Signaling pathways are an important means of communication from the exterior of cell to intracellular
mediators, as well as intracellular interactions that govern diverse cellular processes. Oncogenic mutations
or abnormal expression of signaling components disrupt the regulatory networks that govern cell function,
thus enabling tumor cells to undergo dysregulated mitogenesis, to resist apoptosis, and to promote invasion to
neighboring tissues. Unraveling of dysregulated signaling pathways may advance the understanding of tumor
pathophysiology and lead to the improvement of targeted tumor therapy. In this review article, different signaling
pathways and how their dysregulation contributes to the development of tumors have been discussed.
