VEGF mediated signaling in oral cancer

Lin, X. | Khalid, S. | Qureshi, M.Z. | Attar, Rukset | Yaylim, I. | Ucak, I. | Ismail, M.

Review | 2016 | Cellular and Molecular Biology62 ( 14 ) , pp.64 - 68

Increasingly it is being realized that oral cancer arises from genetic/epigenetic mutations, dysregulations of spatio-temporally controlled signal transduction cascades and loss of apoptosis. Epidemiological studies have provided a stronger association between tobacco use (chewed and smoked) and oral cancer. Nevertheless, alcohol has also gained attention as a significant risk factor, having a multiplicative synergistic cancer promoting effect with tobacco. Vascular Endothelial Growth Factor (VEGF) mediated signaling has gained limelight because of its instrumental role in endothelial cell proliferation, survival, invasion, migratio . . .n, chemotaxis of bone marrow (BM)-derived progenitor cells, vasodilation and vascular permeability. In this review we provide most recent updates on involvement of VEGF/VEGFR signaling axis in oral cancer. We partition this multi-component review into different sections and summarize latest advancements related to therapies against VEGF/VEGFR signaling axis and how microRNAs tactfully modulate VEGF and VEGFR in oral cancers. Data obtained through preclinical and clinical studies has revealed that therapeutic benefits associated with VEGF-targeted therapy are complicated in different cancers and involve myriad of mechanisms. A better understanding of VEGF/VEGFR mediated signaling in oral cancers and testing of novel therapeutic agents in preclinical models will prove to be helpful in effective translation of safest drugs from benchtop to the bedside. © 2016 by the C.M.B Daha fazlası Daha az

Targeting of BCR-ABL: Lessons learned from BCR-ABL inhibition

Lin, X. | Qureshi, M.Z. | Attar, Rukset | Khalid, S. | Tahir, F. | Yaqub, A. | Ismail, M.

Review | 2016 | Cellular and Molecular Biology62 ( 12 ) , pp.129 - 137

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 Daha fazlası Daha az

Regulation of cell signaling pathways by berberine in different cancers: Searching for missing pieces of an incomplete JIG-saw puzzle for an effective cancer therapy

Farooqi, A.A. | Qureshi, M.Z. | Khalid, S. | Attar, Rukset | Martinelli, C. | Sabitaliyevich, U.Y. | Xu, B.

Article | 2019 | Cancers11 ( 4 ) , pp.129 - 137

There has been a renewed interest in the identification of natural products having premium pharmacological properties and minimum off-target effects. In accordance with this approach, natural product research has experienced an exponential growth in the past two decades and has yielded a stream of preclinical and clinical insights which have deeply improved our knowledge related to the multifaceted nature of cancer and strategies to therapeutically target deregulated signaling pathways in different cancers. In this review, we have set the spotlight on the scientifically proven ability of berberine to effectively target a myriad of d . . .eregulated pathways. © 2019 by the authors.

How sesquiterpenes modulate signaling cascades in cancers

Jabeen, S. | Qureshi, M.Z. | Attar, Rukset | Aslam, A. | Kanwal, S. | Khalid, S. | Ismail, M.

Review | 2016 | Cellular and Molecular Biology62 ( 7 ) , pp.110 - 117

Data obtained from high-throughput technologies has started to shed light on the interplay between signal transduction cascades and chromatin modifications thus adding another layer of complexity to the already complex regulation of the protein network. Based on the insights gleaned from almost a decade of research, it has now been convincingly revealed that sesquiterpenes effectively modulated different intracellular signaling cascades in different cancers. In this review we summarize how sesquiterpenes mediated Wnt, Shh, Notch and TRAIL induced signaling cascades. © 2016 by the C.M.B. Association. All rights reserved.

Bitter gourd (Momordica charantia) as a rich source of bioactive components to combat cancer naturally: Are we on the right track to fully unlock its potential as inhibitor of deregulated signaling pathways

Farooqi, A.A. | Khalid, S. | Tahir, F. | Sabitaliyevich, U.Y. | Yaylim, I. | Attar, Rukset | Xu, B.

Article | 2018 | Food and Chemical Toxicology119 , pp.98 - 105

Research over decades has progressively explored pharmacological actions of bitter gourd (Momordica charantia). Biologically and pharmacologically active molecules isolated from M. charantia have shown significant anti-cancer activity in cancer cell lines and xenografted mice. In this review spotlight was set on the bioactive compounds isolated from M. charantia that effectively inhibited cancer development and progression via regulation of protein network in cancer cells. We summarize most recent high-quality research work in cancer cell lines and xenografted mice related to tumor suppressive role-play of M. charantia and its bioac . . .tive compounds. Although M. charantia mediated health promoting, anti-diabetic, hepatoprotective, anti-inflammatory effects have been extensively investigated, there is insufficient information related to regulation of signaling networks by bioactive molecules obtained from M. charantia in different cancers. M. charantia has been shown to modulate AKT/mTOR/p70S6K signaling, p38MAPK-MAPKAPK-2/HSP-27 pathway, cell cycle regulatory proteins and apoptosis-associated proteins in different cancers. However, still there are visible knowledge gaps related to the drug targets in different cancers because we have not yet developed comprehensive understanding of the M. charantia mediated regulation of signal transduction pathways. To explore these questions, experimental platforms are needed that can prove to be helpful in getting a step closer to personalized medicine. © 2018 Elsevier Lt Daha fazlası Daha az
