Recent technological and analytical breakthroughs in genomics and proteomics have deepened our understanding related to the multifaceted nature of cancer. Because of therapeutically challenging nature of cancer, there has been a renewed interest in phytochemistry, and much attention is currently being given to the identification of signaling pathway inhibitors. Data obtained through high-throughput technologies has provided a broader landscape of wiring maps of complex oncogenic signaling networks, thus revealing novel therapeutic opportunities. Increasingly, it is being realized that although our knowledge related to physiological . . .and pathophysiological roles of signal transduction cascades has evolved rapidly, the clinical development of signaling pathway inhibitors has been challenging. Quercetin has attracted considerable attention because of its amazingly high pharmacological value. Research over decades has sequentially shown that quercetin effectively inhibited cancer development and progression. In this review, we have attempted to set the spotlight on the regulation of different cell signaling pathways by quercetin. We partition this multicomponent review into how quercetin effectively regulates the Wnt/ß-catenin pathway, Janus kinase-signal transducer and activator of transcription pathway, and vascular endothelial growth factor/vascular endothelial growth factor receptor signaling cascade in different types of cancers. We also provide an overview of the regulation of NOTCH and SHH pathways by quercetin. MicroRNAs (miRNAs) have also emerged as versatile regulators of cancer, and contemporary studies have shed light on the ability of quercetin to control different miRNAs in various cancers. We have scattered information related to NOTCH and SHH pathways, and future studies must converge on the investigation of these pathways to see how quercetin modulates the signaling machinery of these pathways. © 2018 Wiley Periodicals, Inc Daha fazlası Daha az

Wealth of information gleaned from decades of high-impact research work; scientists have disentangled the complicated web of versatile regulators that underlie cancer development and progression. Use of structural biology approaches and functional genomics have helped us to gain new insights into complex nature of cancer, and it is now clear that genetic/epigenetic mutations, overexpression of oncogenes, inactivation of tumor suppressors, loss of apoptosis, and versatility of protein binding partners have contributory roles in carcinogenesis and metastatic spread. It is becoming progressively more understandable that reprogramming o . . .f gene expression during and nontranscriptional changes during cancer development and progression are initiated and controlled by deregulated signal transduction cascades, all of which collectively create an incalculable complexity. Data obtained through preclinical and clinical trials revealed that alterations in the targeted oncogenes and other downstream, and parallel pathways played a central role in the development of resistance against different therapeutics. Phytochemicals have regained limelight, and different natural products are currently being tested for efficacy in preclinical studies. Apigenin, a plant-derived flavonoid has considerable pharmacological value and is reportedly involved in the regulation of different signaling cascades. In this review, we have attempted to summarize rapidly evolving understanding of molecular biologists and pharmacologists about the potential of apigenin in the regulation of deregulated signaling pathways in different cancers. We have emphasized on the regulation of WNT/ß-catenin and janus kinase/signal transducers and activators of transcription (JAK-STAT) pathways. We also comprehensively discuss how apigenin restored apoptosis in tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-resistant cancers. The review also gives a snapshot of microRNAs (miRNAs) that regulate wide-ranging biological processes, and it is now clear that each miRNA can control hundreds of gene targets. Apigenin was noted to upregulate miR-520b and miR-101 in different cancers to inhibit tumor growth. Moreover, apigenin-induced apoptotic rate was significantly higher when used in combination with miR-423-5p inhibitors or miR-138 mimics. Better comprehension of linear and integrated signaling pathways will be helpful in effective therapeutic targeting of deregulated signaling pathways to inhibit/prevent cancer. © 2018 Wiley Periodicals, Inc Daha fazlası Daha az

Entry of ß-elemene into various phases of clinical trials advocates its significance as a premium candidate likely to gain access to mainstream medicine. Based on the insights gleaned from decades of research, it seems increasingly transparent that ß-elemene has shown significant ability to modulate multiple cell signaling pathways in different cancers. We partition this multicomponent review into how ß-elemene strategically modulates various signal transduction cascades. We have individually summarized regulation of tumor necrosis factor related apoptosis-inducing ligand, signal transducers and activators of transcription, transfor . . .ming growth factor/SMAD, NOTCH, and mammalian target of rapamycin pathways by ß-elemene. Last, we will discuss the results of clinical trials of ß-elemene and how effectively we can use these findings to stratify patients who can benefit most from ß-elemene. © 2019 Wiley Periodicals, Inc Daha fazlası Daha az
