This book was released on 2018-02-19 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroautophagy, the major lysosomal pathway for recycling intracellular components including whole organelles, has emerged as a key process modulating tumorigenesis, tumor–stroma interactions, and cancer therapy. An impressive number of studies over the past decade have unraveled the plastic role of autophagy during tumor development and dissemination. The discoveries that autophagy may either support or repress neoplastic growth and contextually favor or weaken resistance and impact antitumor immunity have spurred efforts from many laboratories trying to conceptualize the complex role of autophagy in cancer using cellular and preclinical models. This complexity is further accentuated by recent findings highlighting that various autophagy-related genes have roles beyond this catabolic mechanism and interface with oncogenic pathways, other trafficking and degradation mechanisms and the cell death machinery. From a therapeutic perspective, knowledge of how autophagy modulates the tumor microenvironment is crucial to devise autophagy-targeting strategies using smart combination of drugs or anticancer modalities. This eBook contains a collection of reviews by autophagy researchers and provides a background to the state-of-the-art in the field of autophagy in cancer, focusing on various aspects of autophagy regulation ranging from its molecular components to its cell autonomous role, e.g. in cell division and oncogenesis, miRNAs regulation, cross-talk with cell death pathways as well as cell non-autonomous role, e.g. in secretion, interface with tumor stroma and clinical prospects of autophagy-based biomarkers and autophagy modulators in anticancer therapy. This eBook is part of the TransAutophagy initiative to better understand the clinical implications of autophagy in cancer.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract Although great strides have been made over the decades in development and optimization of anti-cancer therapies, even highly effective drugs often fail to completely eliminate tumors. Residual tumor cells can enter into a state of dormancy for prolonged periods of time but eventually are able to regain proliferative capacity and reemerge as chemotherapy-resistant disease. Because recurrent disease is a leading contributor to patient's mortality, it is paramount to identify strategies for effectively destroying residual tumor cells. Cytotoxic drugs and ionizing radiation are used as standard therapies in a variety of cancers. These modalities induce apoptosis, autophagy and senescence. Senescence is a state of prolonged growth arrest, which cells are able to eventually escape regaining proliferative capacity. Autophagy is generally considered to be a protective mechanism; however, it can take non-protective or even cytotoxic form in response to anti-cancer treatments. Furthermore, chemotherapy or radiation induced autophagy was shown to be a contributor to the immune response against tumor cells. Using a model of Triple Negative Breast Cancer, we were able to show increased immunosurveillance of tumor cells after enhanced autophagy was achieved by combining epigenetic remodeling with chemotherapy. Alternatively, we were able to achieved effective clearance of tumor cells induced into senescence by chemotherapy or radiation by the senolytic drug ABT-263 (Navitoclax). In summary, autophagy and senescence alone or in concert, can be induced by conventional anti-tumor modalities. Those processes can be modulated independently to achieve clearance of residual tumor cells following anti-cancer therapies.

Book Synopsis The Effects of Autophagy and Senescence on Sensitivity to Cisplatin in Head and Neck Cancer by : Zara Hafeez Siddiqui
Download or read book The Effects of Autophagy and Senescence on Sensitivity to Cisplatin in Head and Neck Cancer written by Zara Hafeez Siddiqui and published by . This book was released on 2020 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: While current treatments in cancer, such as chemotherapy and radiation, can generally be effective in eliminating disease in patients, there also exists the possibility of recurrence of cancer cells over time. In patients diagnosed with locally advanced head and neck carcinoma, about 50-60% develop a loco-regional recurrence within two years, and 20-30% of patients develop metastatic disease at distant sites in the body [5]. On a cellular level, one mechanism for this survival may be that natural mechanisms such as autophagy and senescence play a role in allowing cells to survive after undergoing treatment. One standard of care chemotherapy for head and neck cancer is cisplatin, which was used as the primary treatment in this project. HN12 cells (head and neck tumor cells; p53-null) showed significant growth arrest and decreased viability in response to 5 [mu]M cisplatin treatment, but proliferative recovery over time. It was found that apoptosis did not play a significant role in this growth arrest, as assessed by annexin V/propidium iodide assays to measure apoptotic cell death. Additionally, cisplatin was shown to induce significant levels of autophagy in head and neck tumor cells with acridine orange staining and western blot analysis; however, pharmacological inhibition of autophagy with either chloroquine (5 [mu]M), bafilomycin (5 nM), or 3-methyladenine (1 mM) did not sensitize cells to treatment with cisplatin, indicating a nonprotective role of autophagy. Additionally, HN12 cells showed significant levels of senescence, a form of cellular growth arrest, as indicated by beta-galactosidase upregulation, flattened morphology, and cell cycle arrest. Targeting of senescent cells with the senolytic ABT-263, a Bcl-2/Bcl-xl inhibitor, was effective in sensitizing cells to treatment with cisplatin, but cellular proliferation still occurred over time. Additionally, the HN30 cell line (p53 wild type) was compared to the HN12 line and experiments suggested that p53 status did not play a significant role in induction of autophagy or the sensitization to the senolytic, although more work needs to be done. Overall, these studies provide evidence that autophagy is nonprotective in the HN12 cell line in response to cisplatin treatment, and that senescence plays a role in allowing cells to survive over time. Further, ABT-263 is effective in targeting the remaining population of senescent cells after cisplatin treatment and may be a potential therapeutic mechanism in preventing the recurrence of head and neck cancers.

Download or read book Autophagy written by David A. Gewirtz and published by Elsevier Inc. Chapters. This book was released on 2013-07-29 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is currently a great deal of interest in autophagy, a process whereby a cell digests its constituents to generate energy and metabolic precursors under conditions of stress such as nutrient deprivation. Autophagy may serve as a mechanism for protection of the tumor cell from the effects of radiation and chemotherapy, but may also mediate tumor cell death in response to these challenges. Accumulating evidence indicates that autophagy is also a fundamental characteristic of stem cells, including tumor stem cells. As tumor stem cells are likely to play a central role in tumor dormancy, it appears that autophagy could contribute to the capacity of tumor stem cells to survive for extended periods of time in a dormant state and eventually give rise to recurrent tumors that are primary determinants of morbidity and mortality in cancer patients.
Book Synopsis Senolytics in Disease, Ageing and Longevity by : Daniel Muñoz-Espin
Download or read book Senolytics in Disease, Ageing and Longevity written by Daniel Muñoz-Espin and published by Springer Nature. This book was released on 2020-04-27 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers comprehensive information on the new and rapidly evolving science of identifying and targeting senescent cells, and on the exciting prospect of new diagnostic and therapeutic opportunities for stopping, and even reversing, the progression of disease and the deterioration of the human body due to ageing. According to recent United Nations data, by 2050 one in six people worldwide will be older than age 65, with peaks rising to one in four people in Europe and North America. Remarkably, the number of persons aged 80 years or older is expected to triple, from 143 million in 2019 to 426 million in 2050. First documented in the 1960s, the concept of cellular senescence as an underlying cause of ageing has been established in the course of the last decade. Using genetically engineered mouse models, researchers have demonstrated that the selective elimination of senescent cells can block and even reverse a number of age-related dysfunctions and pathologies, promoting both better health and longer life in the elderly. These include cardiovascular diseases; neurological disorders; type 1 and type 2 diabetes; inflammatory diseases; fibrosis; geriatric syndromes; chronic diseases resulting in organ dysfunction; the integrity of the musculoskeletal system; and cancer. Some senolytic agents have already progressed into trials. These include UBX0101 for the treatment of osteoarthritis (now in phase II), a cocktail of dasatinib and quercetin for the management of idiopathic pulmonary fibrosis and chronic kidney disease, and ABT-263 in combination with senescence-inducing chemotherapies for the treatment of advanced solid tumours. In addition, the book discusses pathways to early phase clinical trials and translational approaches in medicine and ageing, highlighting new opportunities as well as current limitations, challenges and alternatives. Given its scope, it will benefit a broad audience of advanced educators, researchers, graduate students and practitioners.
