Cancer is a multifaceted and genomically complex disease and rapidly accumulating high impact research is deepening our understanding related to the mechanisms underlying cancer development, progression and resistance to therapeutics. Increasingly it is being realized that genetic/epigenetic mutations, inactivation of tumor suppressor genes, overexpression of oncogenes, deregulation of intracellular signaling cascades and loss of apoptosis are some of the extensively studied aspects. Confluence of information suggested that rapidly developing resistance to therapeutics is adding another layer of complexity and overwhelmingly increas . . .ing preclinical studies are identifying different natural agents with efficacy and minimal off-target effects. We partition this multi-component review into citrus fruits and their bioactive ingredients mediating rebalancing of pro- and anti-apoptotic proteins to induce apoptosis in resistant cancer cells. We also discuss how oncogenic protein networks are targeted in cancer cells and how these findings may be verified in preclinical studies
In 1960 researchers reported that balanced translocation between chromosomes 22 and 9 resulted in the generation of Philadelphia chromosome. This breakthrough revolutionized our knowledge related to leukemia biology and contemporary studies revealed that chromosomal translocation resulted in the fusion between the 5' segment of BCR gene and 3' segment of the ABL gene to form BCR/ABL fusion gene. Research over the years has progressively and systematically improved our understanding of the genetic and proteomic basis of Leukemia. Genome-wide profiling studies, including genome sequencing and microarray analysis, have helped us in ide . . .ntification of different intracellular signaling cascades that are frequently mutated in Leukemia. We partition this multi-component review into different sections related to biochemical characteristics of BCR-ABL+ cells, underlying mechanism of generation of mutations and crosstalk of BCR-ABL with various intracellular signaling cascades. We also summarize how BCR-ABL encoding mRNA is negatively regulated by different miRNAs and the strategies which are currently being used to effectively target BCR-ABL protein. We also provide an overview of the natural products which have been used for targeting of BCR-ABL protein. Better understanding of the protein network of Philadelphia positive leukemic cells will prove to be helpful in getting a step closer to personalized medicine
