Rapidly developing resistance against different therapeutics is a major stumbling block in the standardization of therapy. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-mediated signaling has emerged as one of the most highly and extensively studied signal transduction cascade that induces apoptosis in cancer cells. Rapidly emerging cutting-edge research has helped us to develop a better understanding of the signaling machinery involved in inducing apoptotic cell death. However, excitingly, cancer cells develop resistance against TRAIL-induced apoptosis through different modes. Loss of cell surface expression . . . of TRAIL receptors and imbalance of stoichiometric ratios of pro- and anti-apoptotic proteins play instrumental roles in rewiring the machinery of cancer cells to develop resistance against TRAIL-based therapeutics. Natural products have shown excellent potential to restore apoptosis in TRAIL-resistant cancer cell lines and in mice xenografted with TRAIL-resistant cancer cells. Significantly refined information has previously been added and continues to enrich the existing pool of knowledge related to the natural-product-mediated upregulation of death receptors, rebalancing of pro- and anti-apoptotic proteins in different cancers. In this mini review, we will set spotlight on the most recently published high-impact research related to underlying mechanisms of TRAIL resistance and how these deregulations can be targeted by natural products to restore TRAIL-mediated apoptosis in different cancers. © 2019 by the authors.

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

Based on the exciting insights gleaned from decades of ground-breaking research, it has become evident that deregulated signaling pathways play instrumental role in cancer development and progression. Interestingly discovery of non-coding RNAs has revolutionized our understanding related to transcription, post-transcription and translation. Modern era has witnessed landmark discoveries in the field of molecular cancer and non-coding RNA biology has undergone tremendous broadening. There has been an exponential growth in the list of publications related to non-coding RNAs and overwhelmingly increasing classes of non-coding RNAs are a . . .dding new layers of complexity to already complicated nature of cancer. Regulation of TGF/SMAD signaling by miRNAs and LncRNAs has opened new horizons for therapeutic targeting of TGF/SMAD pathway. In this review we have set spotlight on central role of LncRNAs in modulation of TGF/ SMAD pathway. Major proportion of the available evidence is underlining positive role of LncRNAs in contextual regulation of TGF/SMAD pathway. LncRNAs are vital to these regulatory networks because they provide a background support to make the TGF/SMAD mediated intracellular signaling more smooth or make transduction cascade more flexible in response to cues from extracellular environment. Therefore, in accordance with this notion, MALAT1, OIP5-AS1, MIR100HG, HOTAIR, ANRIL, PVT1, AFAP1-AS1, SPRY4-IT, ZEB2NAT, TUG1 and Lnc-SNHG1 have been reported to positively regulate TGF/SMAD signaling. In this review, we have focused on the regulation of TGF/SMAD signaling by LncRNAs and how these non-coding RNAs can be therapeutically exploited. Short-interfering RNA (siRNA) and natural products are currently being tested for efficacy against different LncRNAs. Nanotechnological strategies to efficiently deliver LncRNA-targeting siRNAs are also currently being investigated in different cancers. © 2018 by the C.M.B. Association.

Review | 2020 | Gene737 , pp.1 - 6

There has always been a quest to search for synthetic and natural compounds having premium pharmacological properties and minimum off-target and/or side effects. Therefore, in accordance with this approach, scientists have given special attention to the molecules having remarkable ability to target oncogenic protein network, restore drug sensitivity and induce apoptosis in cancer cells. The mechanisms through which general anesthetics modulated wide-ranging deregulated cell signaling pathways and non-coding RNAs remained unclear. However, rapidly accumulating experimentally verified evidence has started to resolve this long-standing . . . mystery and a knowledge about these important molecular targets has surfaced and how these drugs act at the molecular level is becoming more understandable. In this review we have given special attention to available evidence related to ability of propofol to modulate Wnt/ß-catenin, JAK/STAT and mTOR-driven pathway. Excitingly, great strides have been made in sharpening our concepts related to potential of propofol to modulate non-coding RNAs in different cancers. Collectively, these latest findings offer interesting, unexplored opportunities to target deregulated signaling pathways to induce apoptosis in drug-resistant cancers. © 2020 Elsevier B.V Daha fazlası Daha az

Maslinic acid is gradually gaining attention as an excellent pharmacologically active product because of its premium biological properties. In this review we will focus on chemopreventive properties of Maslinic acid against different cancers. Seemingly, available data is limited and we have yet to unravel how Maslinic acid therapeutically targeted oncogenic cell signal transduction cascades in different cancers. Moreover, there are visible knowledge gaps about the ability of Maslinic acid to modulate oncogenic and tumor . . .suppressor microRNAs in various cancers. © 2018 by the C.M.B.

Central dogma of molecular biology, a term coined by Francis Crick in 1958 was considered to be the cornerstone of molecular biology unless molecular biologists challenged the idea after ground-breaking discovery of non-coding RNAs. Discovery of microRNAs marked a new era and revolutionized our understanding related to puzzling mysteries about intermediate steps between transcription and translation. Technological advancements have spawned a multitude of platforms for profiling of long-noncoding RNAs and miRNAs in different cancers. Detailed investigation of mRNA targets of miRNAs has enabled high-order analyses of interconnected ne . . .tworks and revealed affected pathways in different cancers. miR-143 has emerged as a multi-talented tumor suppressor microRNA having considerable ability to inhibit and prevent cancer via regulation of myriad of oncogenes. In this review, we will summarize most recent evidence related to characteristically unique ability of miR-143 to target different oncogenic mRNAs in different cancers. We will also comprehensively discuss how scientists have identified multiple long non-coding RNAs reportedly involved in promoting the expression of oncogenes by interfering with miR-143 mediated targeting of these oncogenes. Because of excellent ability of miR-143 to effectively target oncogenic mRNAs, researchers have started to focus on use of miR-143 mimics to restore expression of miR-143 in various cancers 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

Ampelopsin or Dihydromyricetin is gradually emerging as a high-quality natural product because of its ability to modulate wide-ranging signaling pathways. Ampelopsin (Dihydromyricetin) has been reported to effectively modulate growth factor receptor (VEGFR2 and PDGFRß) mediated signaling,  TRAIL/TRAIL-R pathway, JAK/STAT and mTOR-driven signaling in different cancers. Ampelopsin (Dihydromyricetin) has also been shown to exert inhibitory effects on the versatile regulators which trigger EMT (Epithelial-to-Mesenchymal Transition). Findings obtained from in-vitro studies are encouraging and there is a need to comprehensively analyze ho . . .w Ampelopsin (Dihydromyricetin) inhibits tumor growth in different cancer models. Better knowledge of efficacy of Ampelopsin (Dihydromyricetin) in tumor bearing mice will be helpful in maximizing its translational potential Daha fazlası Daha az

Regulation of Kisspeptin mediated signaling by non-coding RNAs in different cancers: the beginning of a new era

Farooqi, A.A. | Attar, Rukset | Bageshlooyafshar, B. | Sabitaliyevich, U.Y. | Nurmurzayevich, S.B. | Yelekenova, A.B. | Gormus, U.

Review | 2019 | Cellular and molecular biology (Noisy-le-Grand, France)65 ( 3 ) , pp.72 - 75

Kisspeptin-driven intracellular signaling has captured enormous attention because of its central role in cancer onset and progression. Wealth of information has helped us to develop a better understanding of the critical roles of Kisspeptin-mediated signaling in different cancers. However, astonishingly, we have not yet drilled down deep into the mysterious aspects associated with non-coding RNA mediated regulation of Kisspeptin-driven signaling. Therefore, in this mini-review, we will comprehensively analyze available evidence related to miRNAs and long non-coding RNAs (LncRNAs) and their ability to modulate Kisspeptin-mediated sig . . .naling. There are visible knowledge gaps about interplay between non-coding RNAs and Kisspeptin-mediated signaling. It will be appropriate to say that we have just started to scratch the surface of an entirely new regulatory layer of Kisspeptin-mediated transduction cascade. Mechanistically, it has been revealed that inhibition of Kisspeptin mediated signaling activated and stimulated the entry of NF?B into the nucleus to stimulate expression of proteins which can sequentially inactivate tumor suppressor miRNAs. miRNAs have also an instrumental role in regulation of proteins which post-translationally modify and inhibit KISS1 expression. It is becoming progressively more understandable that LncRNAs act as miRNA sponges and protect oncogenic mRNAs. However, these facets are also incompletely investigated. Identification of LncRNAs which interfere with Kisspeptin-mediated pathway either through acting as miRNA sponges or working with methylation-associated machinery will be helpful in sharpening the resolution of the pixels of the regulatory network which shapes Kisspeptin-mediated signaling Daha fazlası Daha az
