Available in PDF, EPUB and Kindle. Book excerpt: The Special Issue on high grade serous ovarian cancer (HGSOC) and the contribution of the tumor microenviroment (TME) consists of reviews contributed by leaders in the OC field. As HGSOC metastases have a highly complex TME, there is an urgent need to better understand the TME in general, its distinct components in particular, and the role of the TME in the context of disease recurrence and development of chemoresistance. The Special Issue incorporates the current understanding of the different parts of thd TME components, including the cancer cells themselves, the cells surrounding the cancer cells or stromal cells, and the cells of the immune system, which are attracted to the site of metastases. In addition to these cells of the TME, the role of various cellular factors made by the cells of the TME are also the subject of the reviews. In addition, reviews in this Special Issue cover the complex relationships between the molecular mechanisms of HGSOC progression, including genomic, epigenomic and transcriptomic changes and changes in the immune cell landscape, as these may provide attractive new molecular targets for HGSOC therapy.

Book Synopsis Advances in Epithelial Ovarian Cancer: Model Systems, Microenvironmental Influences, Therapy, and Origins by : Viive Maarika Howell
Download or read book Advances in Epithelial Ovarian Cancer: Model Systems, Microenvironmental Influences, Therapy, and Origins written by Viive Maarika Howell and published by Frontiers Media SA. This book was released on 2016-02-03 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This eBook provides a compendium of the current state-of-the-art in research tools for, and understanding of, the critical research areas in epithelial ovarian cancer (EOC) with a strong emphasis on (HG-SOC). Research areas covered include therapy response and development, microenvironmental influences and the etiology and progression of EOC. Ten articles detail established and novel in vivo and in vitro model systems. These include primary and immortalized cell culture in 2D and 3D as well as genetically engineered, transgenic, spontaneous, syngeneic, classical xenograft and patient derived xenograft mouse models. The generation of genetically engineered mouse models of HG-SOC has been a major dilemma as models with the oncogenic aberrations common in the human malignancy do not accurately recapitulate HG-SOC. Conversely, commonly used HG-SOC cell lines have been found to not harbor the expected genetic changes. These issues as well as the rapid acceptance of patient derived xenograft models are reviewed. Five articles discuss different aspects of the tumor microenvironment including its role in therapy resistance, disease progression and metastasis. Mutation of BRCA1/2 continues to be the best defined risk factor for HG-SOC. Three articles discuss BRCA-loss in the context of disease development, targeted therapies and changes in preventative measures proposed for mutation carriers in light of the recent advances in knowledge regarding the origins of this malignancy. An image of HG-SOC with reduced BRCA1 expression is featured on the cover (image by VM Howell). A major clinical issue for patients with HG-SOC is the development of therapy resistance. Five articles focus on therapy resistance and different ways to overcome resistance. Overall, this eBook is an outstanding resource to aid researchers design their programs of research and determine the most appropriate and up-to-date EOC model systems to address their research questions.
Book Synopsis Deciphering the Immunosuppressive Landscape of High-grade Serous Ovarian Cancer by : Julian Smazynski
Download or read book Deciphering the Immunosuppressive Landscape of High-grade Serous Ovarian Cancer written by Julian Smazynski and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High-grade serous ovarian cancer (HGSC) remains the most common and lethal subtype of ovarian cancer with a 5-year survival rate of ~30%, highlighting an urgent need for new treatments. Cancer immunotherapy has emerged as an efficacious strategy aimed at harnessing the exquisite capabilities of our immune system to destroy malignant cells. However, the development of more effective immunotherapies is hampered by our limited understanding of the phenotype of bona fide tumor-reactive T cells versus irrelevant bystanders. Further, T cells that exhibit tumor specificity appear to encompass a tissue resident memory (TRM) phenotype but combat a harsh immunosuppressive tumor microenvironment, often leading to an exhausted phenotypic state and evasion of immune-mediated destruction. These insights have led to rapid clinical implementation of so-called "checkpoint blockade" therapies that re-invigorate T cell-mediated tumor destruction by blocking surface inhibitory receptors or ligands. Thus, by identifying the phenotype of prognostically favourable TRM T cells and the immunosuppressive networks they face, my thesis work tackles a critical challenge in designing the next generation of therapeutic interventions for this disease. To address this challenge, I hypothesized that (1) the TRM phenotype could be modulated for improving adoptive T cell therapy; (2) TRM TIL characterized by the co-expression of CD103, PD-1, and CD39 in HGSC provide improved prognostic benefit indicative of enriched tumor reactivity; (3) the TIGIT/CD155 signalling axis plays a crucial role in shaping the immunosuppressive landscape impeding TRM T cells in HGSC. Firstly, I developed methods for modulating the TRM phenotype on expanded human and murine T cells for adoptive cell therapy and assessed the therapeutic impact of these phenotypes. Secondly, we applied high-dimensional flow cytometry, single-cell sequencing, and multiplexed immunofluorescence to primary human HGSC specimens to explore the single-cell phenotypic profiles and prognostic significance of tumor-infiltrating T cells co-expressing three putative markers of tumor reactivity: CD39, CD103, and PD-1. These 'triple-positive' T cells exhibited a highly activated/exhausted phenotype and superior prognostic value relative to all other T-cell subsets, suggesting these markers enrich for tumor-reactive clones. Furthermore, these triple-positive cells exhibited heightened expression of the inhibitory checkpoint TIGIT, which plays a prominent role in tumor-mediated immune suppression. Finally, to explore the therapeutic implications of this finding, we investigated the relationship between the TIGIT signaling axis on TIL and prognosis in HGSC. Once again utilizing high-dimensional flow cytometry, multi-color histological imaging, and gene expression profiling we found T cells from HGSC frequently express TIGIT ex vivo and post-clinical expansion. Further, CD155, the dominant ligand for TIGIT, was largely expressed on malignant epithelium in HGSC and showed a negative association with immune infiltration. Thus, TRM T cells represents a compelling immunotherapeutic immune subset in HGSC and one that could be bolstered by immune checkpoint inhibition of the TIGIT/CD155 axis.

Book Synopsis Ovarian Cancers by : Eric Pujade-Lauraine
Download or read book Ovarian Cancers written by Eric Pujade-Lauraine and published by Springer. This book was released on 2016-10-17 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the latest developments in the concepts and management of ovarian cancer. The new data presented throughout opens the way to radically different therapeutic approaches. Surgery remains the core of ovarian cancer treatment, but its ultimate goal and the standard surgical procedure have evolved, giving rise to the question of how to label expert centers for debulking surgery. Neo-adjuvant chemotherapy is becoming more popular and is also a new field for testing novel drug combinations. Over recent years, ovarian cancer management has embraced molecular biology. It is now more correct to talk about cancers of the ovary rather than ovarian cancer, since it is not a unique disease but several entities with different molecular drivers. The significant advances in drugs targeting the microenvironment or the tumor cell DNA repair mechanisms are presented in detail together with exciting future perspectives. All these advances would not have been possible without collaborative groups such as the GINECO group in France and their integration in wider clinical research networks at the European (ENGOT) and international (GCIG) level.

Book Synopsis Differential Expression at the Proteomic Level of Stem-cell Markers and Other Gene Markers in High-grade Serous Vs. Other Subtypes of Ovarian Cancer by : Lipilekha Mukherjee
Download or read book Differential Expression at the Proteomic Level of Stem-cell Markers and Other Gene Markers in High-grade Serous Vs. Other Subtypes of Ovarian Cancer written by Lipilekha Mukherjee and published by . This book was released on 2017 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ovarian carcinoma is the most lethal neoplasm and the fifth leading cause of death in women due to gynecological malignancies. It is estimated that there are 225,000 new cases diagnosed and 140,000 deaths occurring annually worldwide. Among the different subtypes, widely heterogeneous high-grade serous ovarian cancer (HGSOC) poses a great challenge to modern chemotherapy due to its high recurrence rate and resistance to standard treatments. Both of those causes are linked to the presence of a small subpopulation of cancer stem cells (CSCs) in the tumor microenvironment. Recent studies suggest that survival timeline and disease recurrence are linked to the variable expression of both cancer CSC and other gene biomarkers in cancer cells. Therefore, using Western blot and immunohistochemistry analyses, we assessed the expression of a host of CSC and other gene products at the whole-cell level in total protein extracts and sub-cellular levels in PFA-fixed cells from three HGSOC and five non-HGSOC cell lines. We found that no CSCmarkers were expressed in monolayer two-dimensional cultures that could differentiate HGSOCs from non-HGSOCs. In fact, no CSC-biomarker proteins were detected in any of the subtypes of the cancer-cell lines in our studies. Upon assessing other gene biomarkers at the proteomic level, we observed prominent differential expression patterns among the HGSOC and non-HGSOC subtypes and even within a subtype but no definite pattern to distinguish HGSOCs from non- HGSOCs. In conclusion, determining a differential protein expression profile in subtypes of ovarian cancer requires much further attention in order to provide earlier detection methods and personalized treatment options for patients.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: Tumor establishment, metastatic spreading and poor survival in ovarian cancer is strongly associated with progressive derangement of the patientu2019s immune system. Accumulating evidence suggests that immune impairment is influenced by the production and presence of cytokines in the tumor microenvironment.Methods: Cytokine mRNA profiles in tumor tissue and peripheral blood mononuclear cells (PBMC) were analyzed in patients with high grade serous carcinoma (HGSC) of the ovary and compared to patients with benign ovarian conditions and controls with normal ovaries. Cytokine assessment was done by real-time quantitative RT-PCR and specific primers and probes for 12 cytokines-IFN-u03b3, IL-1u03b2, IL-2, IL-4, IL-6, IL-8, IL-10, IL-15, TNF-u03b1, TNF-u03b2/LTA, TGF-u03b21, and GM-CSF chosen to distinguish between cytotoxic Th1, humoral Th2, regulatory Th3/Tr1 and inflammatory responses.Results: The cytokine mRNA response in the HGSC patients was significantly up regulated compared to patients with benign ovarian conditions and normal ovary controls confirming the immunogenicity of HGSC and implying immune recognition and reaction locally in the tumor microenvironment and systemically in the peripheral blood. There was an up-regulation of inflammatory and inhibitory cytokine mRNA promoting tumor progression, T-regulatory cell priming and T-regulatory cell-mediated immune suppression. In contrast, there was an inability to mount the crucially important IFN gamma response needed for upregulation of the cytotoxic anti-tumor response in the local microenvironment. In addition, systemic IL-4- mediated Th2 response prevailed in the peripheral blood deviating the systemic defense towards humoral immunity.Conclusions: Taken together, these results suggest local and systemic cytokine cooperation promoting tumor survival, progression and immune escape. Our study confirms and extends previous investigations and contributes to the evaluation of potential cytokine candidates for diagnostic cytokine mRNA profiles and for future therapeutic interventions based on cytokine inhibition.
