Write a 6 page essay on Targets of Anti-metastatic Drug Development.
Therefore, in this literature review, the paper describes some of the candidate targets for the anti-metastatic drugs development and the progress that has been made, so far, in developing effective drugs.
It is clear that driving oncogenic mutations are necessary for metastasis. A number of the oncogenic mutations so far identified affect cell fate regulation, genomic maintenance and cell survival (Glinsky and Raz, 2010, p. 1788). . These initiating and resultant progression events may also turn out indispensable for metastases establishment at a secondary site. Patient analysis has shown that agents targeting oncogenic mutations or amplifications, such as mutant BRAF in melanoma, amplified HER2 in breast-cancer, have demonstrated substantial effects controlling metastatic disease (Platt and Raz, 1992, P. 438),.
Nonetheless, metastasis disease treatment might be sophisticated by the differential demonstration, activity or a combination of oncogenes in metastases during metastatic recurrence (McGarty and Block, 2006, p. 151). For instance, HER2 expression is high in estrogen receptor (ER)+HER2- of luminal breast cancer cells via tumour necrosis factor fantasticfamily member 11-RABKL signalling in the microenvironment of bones. The effectiveness of targeted therapies concerning metastatic environments is presently limited through the drug resistance that often happens in metastatic relapse. Resistance of this nature is always because of the coming up of de novo mutations. Furthermore, the adaptive ability of oncogenic signalling networks for overcoming monotherapy attract new drug targets as well as strategies for inhibiting feedback-regulated pathways. Therefore, constant efforts to maximize target therapies for such oncogenic drivers and to defeat drug resistance will be essential for treating metastatic disease.
It has been found that tumour cells augment their intrinsic mobility through adopting cellular programs that
