Example text

Once that initial invasion takes place, the disease evolves through progressive spreading stages: local invasion, regional metastasis (mostly lymph nodes), distant metastasis. 3 Local Invasion Local invasion is a complex process that depends on a series of steps. Some of the cellular functions (and their corresponding genes) involved in tumor invasion are attachment (integrins, CD44, VLA-4, ICAM-1, OPN), dissociation (cadherins), basement membrane disruption (collagens, fibronectin, elastin, proteoglycans), proteolysis of ECM (matrix metalloproteinases, interstitial collagenases, stromelysins, gelatinases, TIMPs), and motility (HGF, IGF-II, ATX, vitronectin, fibronectin, laminin, type I and IV collagen, thrombospondin, IGF-I, IL-8, histamine) [4].

To understand the complexity of the molecular changes involved in cancer, it is important to keep in mind that many genes may play a role in more than one of these functions. As an example, p53 is a TSG that is inactivated in a significant proportion of cancers and plays a role in several p53-dependant apoptosis pathways [87] or is involved in p53-mediated inhibition of tumor angiogenesis [88]. In addition, it has been shown that p53 plays central roles in DNA repair [89] regulation of cell motility [90].

Correlation of these signatures with clinical observations can yield information useful to physicians in support of patient management decisions such as selection of effective cancer treatment. In addition, the ability to rapidly and efficiently identify a reliable set of disease-specific biomarkers is key to enable a future of personalized medicine. A significant challenge for the medical community is to devise practical means to discover these complex molecular signatures in the clinical setting.
