Book excerpt: Exosomes are nano-vesicles released into the microenvironment by different cell types including normal and cancer cells. Initial studies showed that these extracellular vesicles are used by cells to get rid of obsolete cellular molecules, toxic end products and drugs. Exosomes have acquired a lot of attention because of their ability to act as mediator of cell-cell communication. They have tetraspanin proteins on their membrane and contain lipids, proteins, mRNAs and non-coding RNAs. In this work we explore the potential of exosomal microRNAs and IncRNAs as mediators of cell communication. In this study, we demonstrate that exosomes carrying non-coding RNA can be transferred among different cell lines through direct uptake. We show that miR-10b, highly expressed in metastatic breast cancer MDA-MB-231 cells as compared to non-metastatic breast cancer cells or nonmalignant breast cells, is actively secreted into conditioned medium via exosomes. In particular, nSMase2 or ceramide promotes the exosome-mediated miR-10b secretion whereas ceramide inhibitor suppresses this secretion. Moreover, upon uptake, miR-10b can suppress the protein level of its target genes such as HOXD10 and KLF4, indicating its functional significance. Finally, treatment with exosomes derived from MDA-MB-231 cells could induce the invasion ability of nonmalignant HMLE cells. We also found that IncRNA BC200 is upregulated in breast cancer and actively secreted by cancer cells. BC200 is transcriptionally induced by estradiol (E2) in ER positive breast cancer cell lines and is vital for cell growth and viability. BC200 knockout, generated using CRISPR/Cas9 technique induces growth inhibition and cell apoptosis. Of great interest, BC200 knockout enhances expression of pro-apoptotic bcl-XS variant at both mRNA and protein level. Further studies confirmed that BC200 binds with hnRNP A2/B1 and thereby facilitates binding of hnRNP A2/B1 with bcl-X mRNA. In vivo study in mice shows that BC200 knockout MCF-7 cells had a marked reduction in tumor weight as compared to donor control tumor. The regulation of bd-X alternative splicing depends upon endogenous expression of BC200 that would help hnRNP A2/B1 to position itself on bd-X mRNA and modulate splicing in favor of bcl-XL. Thus, loss of BC200 leads to generation of bcl-XS protein synthesis and apoptosis. Together, these results suggest that BC200 functions as a negative regulator of apoptosis in breast cancer and thus, it may serve as a potential target for cancer therapies. Work done in this study suggests that a set of specific non-coding RNAs may play an important role in modulating tumor microenvironment through exosomes. Thus, a better understanding of this process may aid in the development of novel therapeutic agents.

This book was released on 2023-03-14 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Non-coding RNA Transcripts in Cancer Therapy: Pre-clinical and Clinical Implications' provides a new insight towards role of non-coding RNAs molecules including microRNAs, long non-coding RNAs and circular RNAs in cancer. The reason of focusing on cancer is that this malignant disease is responsible for high death around the world and after cardiovascular diseases, it is a leading cause of death. In the current book, the basic information and knowledge about ncRNAs, their biogenesis and their biological functions are covered. It is shown that ncRNAs can regulate expression level of genes at transcriptional and post-transcriptional levels and therefore, ncRNAs are master and key players in molecular pathways. Then, the impact of regulation of molecular pathways by ncRNAs on important molecular mechanisms such as proliferation, metastasis, epithelial-to-mesenchymal transition, apoptosis and autophagy are described. All of these aspects are integrated in cancer and for treatment of this disease. In case of miRNAs, their biogenesis and biological functions in physiological conditions are described. Then, impact of miRNAs on proliferation, metastasis, therapy response (drug resistance and radio-resistance) is described. For lncRNAs and circRNAs, a same way is followed and their biogenesis and functional roles in cells are discussed. At the next step, function of lncRNAs and circRNAs in regulating proliferation, metastasis and therapy response (chemoresistance and radio-resistance) is introduced. These subjects are discussed based on pre-clinical studies and in order to make the book more comprehensive and broaden its scope, the function of exosomal ncRNAs in diagnosis and prognosis of cancer patients is described.

Download or read book Intercellular Communication in Cancer written by Mustapha Kandouz and published by Springer. This book was released on 2015-11-20 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells are by nature compelled to live in groups. They develop dependence over signaling cues received from their microenvironment, in particular from other cells, whether of their own “kind” or of a different type. Therefore, communicating with these cells is a critical aspect of their behavior and fate, as they live and die normally or as they undergo disease-related pathological changes, with dramatic repercussions. In this book, we have asked expert researchers in the field of Intercellular Communication in Cancer to provide chapters on different aspects of interaction between neighboring cells, in the context of cancer diseases. We have specifically focused our efforts on membrane-to-membrane contact-based rather than growth factors-mediated modes of intercellular communications. The contributing authors provide an extensive overview of their respective area of specialization, with an in-depth discussion of the molecular mechanisms of cell-cell interactions, the impact on tumor progression and response to therapies, as well as the cancer diagnostic value of this scientific information. This book aims to introduce essential aspects of the normal and pathological cellular fate and homeostasis to both scientists and clinicians, and also to provide established researchers with an update on the novelties and future directions this expanding field is witnessing.

Download or read book Exosomes and MicroRNAs in Biomedical Science written by Hamed Mirzaei and published by Springer Nature. This book was released on 2022-06-06 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: MicroRNAs (miRNAs) are a member of the family of non-coding RNA molecules, and consist of small conserved sequences between 19–25 nucleotides in length that are responsible for regulating many cellular functions by affecting a wide range of messenger RNAs in a sequence specific manner. Fundamental biological processes like cell proliferation and growth, stress resistance, tumorigenesis, fat metabolism, and neural development have all been shown to be governed by miRNAs. miRNAs carry out the post-transcriptional silencing of gene expression via targeting the 30-untranslated region (UTR) of the complementary mRNA sequence. The dysregulation of the expression levels of various miRNAs is typical of tumor cells, and has been associated with tumor progression and poor prognosis. Many miRNAs are up-regulated in cancer, where they can silence tumor suppressor genes such as apoptosis and immune response associated genes. Therefore, it is possible to profile the expression levels of miRNAs as biomarkers, in order to diagnose cancer and noncancerous diseases. Moreover, cancer detection in the early stages is crucial in clinical situations. Characterization of miRNAs in serum, plasma, and other bodily fluids, and understanding their stability against RNase degradation, is important to assess their suitability as biomarkers and diagnostic tools. Exosomes play an important role in inter-cellular communications, and these nanosized particles have various functions in diverse physiological pathways, in normal as well as abnormal cells. Exosomes can carry diverse cargos such as mRNAs, miRNAs, and proteins that transfer information between donor and recipient cells. Furthermore, uptake of exosomes and their cargos may promote or suppress various molecular and cellular pathways, which alter the cellular behavior. Many reports have discussed the role of exosomes released from cancer cells on the progression of cancer at various stages. Exosomes and their cargos may affect the growth of the tumor, metastasis, drug resistance, immune system function, as well as angiogenesis. Therefore, exosomes have been explored as diagnostic biomarkers in many cancers. Moreover, exosomes can be used as biological vehicles to deliver different drugs and agents like doxorubicin (DOX), miRNAs, and siRNAs. The present book covers the role of exosomes and micro-RNAs in the pathogenesis and treatment of various diseases.

Download or read book The M2 Macrophage written by Tamás Röszer and published by Springer Nature. This book was released on 2020-08-03 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophages are core components of the innate immune system. Once activated, they may have either pro- or anti-inflammatory effects that include pathogen killing, safe disposal of apoptotic cells or tissue renewal. The activation state of macrophages is conceptualized by the so-called M1/M2 model of polarization. M2 macrophages are not simply antagonists of M1 macrophages; rather, they represent a network of tissue resident macrophages with roles in tissue development and organ homeostasis. M2 macrophages govern functions at the interfaces of immunity, tissue development and turnover, metabolism, and endocrine signaling. Dysfunction in M2 macrophages can ruin the healthy interplay between the immune system and metabolic processes, and lead to diseases such as insulin resistance, metabolic syndrome, and type 1 and 2 diabetes mellitus. Furthermore, M2 macrophages are essential for healthy tissue development and immunological self-tolerance. Worryingly, these functions of M2 macrophages can also be disrupted, resulting in tumor growth and autoimmunity. This book comprehensively discusses the biology of M2 macrophages, summarizes the current state of knowledge, and highlights key questions that remain unanswered.

This book was released on 2014-02-10 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tumor-Induced Immune Suppression - Prospects and Progress in Mechanisms and Therapeutic Reversal presents a comprehensive overview of large number of different mechanisms of immune dysfunction in cancer and therapeutic approaches to their correction. This includes the number of novel mechanisms that has never before been discussed in previous monographs. The last decades were characterized by substantial progress in the understanding of the role of the immune system in tumor progression. Researchers have learned how to manipulate the immune system to generate tumor specific immune response, which raises high expectations for immunotherapy to provide breakthroughs in cancer treatment. It is increasingly clear that tumor-induced abnormalities in the immune system not only hampers natural tumor immune surveillance, but also limits the effect of cancer immunotherapy. Therefore, it is critically important to understand the mechanisms of tumor-induced immune suppression to make any progress in the field and this monograph provides these important insights.
