lüll Pro-oncogenic and anti-oncogenic pathways: opportunities and challenges of cancer therapy Zhang J; Chen YH; Lu QFuture Oncol 2010[Apr]; 6 (4): 587-603Carcinogenesis is the uncontrolled growth of cells gaining the potential to invade and disrupt vital tissue functions. This malignant process includes the occurrence of 'unwanted' gene mutations that induce the transformation of normal cells, for example, by overactivation of pro-oncogenic pathways and inactivation of tumor-suppressive or anti-oncogenic pathways. It is now recognized that the number of major signaling pathways that control oncogenesis is not unlimited; therefore, suppressing these pathways can conceivably lead to a cancer cure. However, the clinical application of cancer intervention has not matched up to scientific expectations. Increasing numbers of studies have revealed that many oncogenic-signaling elements show double faces, in which they can promote or suppress cancer pathogenesis depending on tissue type, cancer stage, gene dosage and their interaction with other players in carcinogenesis. This complexity of oncogenic signaling poses challenges to traditional cancer therapy and calls for considerable caution when designing an anticancer drug strategy. We propose future oncology interventions with the concept of integrative cancer therapy.|Antineoplastic Agents/pharmacology/*therapeutic use[MESH]|Humans[MESH]|Neoplasms/*drug therapy[MESH]|Proto-Oncogenes/drug effects[MESH]|Signal Transduction/drug effects[MESH] |
