Download or read book Molecular mechanisms of cellular stress responses in cancer and their therapeutic implications written by Megan Chircop and published by Frontiers Media SA. This book was released on 2015-03-06 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to stress, cells can activate a myriad of signalling pathways to bring about a specific cellular outcome, including cell cycle arrest, DNA repair, senescence and apoptosis. This response is pivotal for tumour suppression as all of these outcomes result in restriction of the growth and/or elimination of damaged and pre-malignant cells. Thus, a large number of anti-cancer agents target specific components of stress response signalling pathways with the aim of causing tumour regression by stimulating cell death. However, the efficacy of these agents is often impaired due to mutations in genes that are involved in these stress-responsive signalling pathways and instead the oncogenic potential of a cell is increased leading to the initiation and/or progression of tumourigenesis. Moreover, these genetic defects can increase or contribute to resistance to chemotherapeutic agents and/or radiotherapy. Modulating the outcome of cellular stress responses towards cell death in tumour cells without affecting surrounding normal cells is thus one of the ultimate aims in the development of new cancer therapeutics. To achieve this aim, a detailed understanding of cellular stress response pathways and their aberrations in cancer is required. This Research topic aims to reflect the broadness and complexity of this important area of cancer research.

Download or read book Cellular Response to Physical Stress and Therapeutic Application written by Kondo Takashi Shimizu Tadamichi and published by . This book was released on 2014-05-14 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not all that cannot be seized is an illusion! Many effective powers in nature cannot be seized, including magnetism, electricity and sound. However, they contribute to shaping the quality of human life on a daily basis, transcending health and disease as they interact with the human body. Magnetism is important for stability on earth; however, exposure of the body to magnetic fields is not inert. Such exposure has been reported to alter hormone secretion and stimulate bone formation in vivo. Its coupling with electricity provides light and heat to our planet at certain wavelengths. Yet, the infiltration of shorter or longer wavelengths can be disastrous. For instance, ultraviolet radiation can cause inflammatory skin reactions and carcinogenesis at certain levels. In addition, ionizing radiation is claimed to be the driving force for the origin of power resources on earth, while human exposure to radiation is related to the world's most devastating events. On the other hand, sound, which is a mechanical wave, has been reported to affect cells at inaudible levels, causing alterations in the gene expression and cell death. All these energies as such are identified to exert physical stresses in a biological milieu especially when thresholds of exposure are exceeded. But still "hard times" have significance! Researchers have been accumulating knowledge on the biological effects of these physical stressors and their underlying mechanisms on the molecular and genetic levels, that over years they were able to achieve control over these physical stressors for the benefit of human kind. Nowadays, we see most of these energies employed in diagnosis such as magnetic resonance imaging (MRI) and ultrasound as well as in therapeutics. In our rigorous war against cancer, numerous patients have been cured from tumors by physical means such as ionizing radiation, heating (RF and MW hyperthermia or ablation) or high intensity focused ultrasound (HIFU). Through the chapters of this book, the readers will get introduced to such physical stressors and their biological effects. Recent findings on molecular mechanisms will be thoroughly presented. In addition, perspectives on the modulation of these energies to achieve further therapeutic advantages will be discussed.

Download or read book Using Phylogenetically Conserved Stress Responses to Discover Natural Products with Anticancer Activity written by and published by . This book was released on 2005 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: One unique feature of cancer cells that can be exploited for anticancer drug discovery is their dependence on their own cellular stress responses to survive the stressful acidotic, hypoxic and nutrient-deprived conditions within the tumor. Reasoning that desert organisms surviving under stressful conditions may have evolved to produce small molecule metabolites capable of modulating heat shock protein 90 (Hsp90) function, and/or other cell stress responses, we employed the cellular heat shock response in a moderate-throughput phenotypic assay. This strategy has resulted in the isolation and characterization of a number of small molecule natural products with heat shock induction activity from these organisms. Three such natural products are the subject of this study. In a limited structure-activity relationship (SAR) study, a previously known Hsp90 inhibitor radicicol (RAD), and several structurally related molecules including the fungal metabolite monocillin 1 (MON) were found to interact with Hsp90. In addition, RAD and MON were shown to lead to the degradation of Hsp90 client proteins involved in the cancer cell survival the estrogen receptor (ER) and the insulin-like growth factor receptor 1 (IGF-1R). We further characterized MON and showed that by targeting the molecular chaperone Hsp90, this compound induces components of the heat shock response at the transcriptional and translational levels, and leads to the acquisition of a thermotolerant phenotype in seedlings of the plant Arabidopsis thaliana. These findings support our hypothesis that there is ecological significance to the elaboration of small molecules that target stress responses. A number of extracts active in our phenotypic assay contained small molecules with no apparent Hsp90 activity. One such extract afforded terrecyclic acid A (TCA) with significant anti-tumor activity against a panel of human cancer cell lines. To characterize the biological activities of TCA we examined three key stress responsesthe heat shock, oxidative, and inflammatory responsesand show that TCA destabilizes these pathways associated with cancer cell survival through induction of oxidative stress (ROS), and inhibition of NF-kappaB transactivation. The isolation of RAD, MON and TCA from Sonoran desert organisms provides proof of principle that we have developed an effective strategy for the discovery of small molecule modulators of cellular stress responses that can serve as leads for the development of new anticancer drugs with novel mechanisms of action.

Download or read book Heat Shock Proteins in Cancer written by Stuart K. Calderwood and published by Springer Science & Business Media. This book was released on 2007-09-09 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat shock proteins are emerging as important molecules in the development of cancer and as key targets in cancer therapy. These proteins enhance the growth of cancer cells and protect tumors from treatments such as drugs or surgery. However, new drugs have recently been developed particularly those targeting heat shock protein 90. As heat shock protein 90 functions to stabilize many of the oncogenes and growth promoting proteins in cancer cells, such drugs have broad specificity in many types of cancer cell and offer the possibility of evading the development of resistance through point mutation or use of compensatory pathways. Heat shock proteins have a further property that makes them tempting targets in cancer immunotherapy. These proteins have the ability to induce an inflammatory response when released in tumors and to carry tumor antigens to antigen presenting cells. They have thus become important components of anticancer vaccines. Overall, heat shock proteins are important new targets in molecular cancer therapy and can be approached in a number of contrasting approaches to therapy.

This book was released on 2016-12-28 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autophagy: Cancer, Other Pathologies, Inflammation, Immunity, Infection, and Aging is an eleven volume series that discusses in detail all aspects of autophagy machinery in the context of health, cancer, and other pathologies. Autophagy maintains homeostasis during starvation or stress conditions by balancing the synthesis of cellular components and their deregulation by autophagy. This series discusses the characterization of autophagosome-enriched vaccines and its efficacy in cancer immunotherapy. Autophagy serves to maintain healthy cells, tissues, and organs, but also promotes cancer survival and growth of established tumors. Impaired or deregulated autophagy can also contribute to disease pathogenesis. Understanding the importance and necessity of the role of autophagy in health and disease is vital for the studies of cancer, aging, neurodegeneration, immunology, and infectious diseases. Comprehensive and forward-thinking, these books offer a valuable guide to cellular processes while also inciting researchers to explore their potentially important connections.
