This book was released on 2013 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breast cancer is a serious public health issue, and a full understanding of its etiology and pathophysiology is a primary focus in the field. Molecularly, the combined action of a plethora of factors in multiple pathways is involved in the regulation of the breast tumoriogenic process. Characterization of a more complete spectrum of the molecular factors will provide insights into the development of new and improved diagnostic, prognostic and therapeutic tools for treating breast cancer. To this end, my studies utilize a combination of molecular biology and bioinformatic methods, to uncover the mechanisms underlying the regulation of gene expression and growth in human breast cancer cells. To investigate the molecular crosstalk of the estrogen and c-Jun N-terminal kinase 1 (JNK1) signaling pathways, I monitored the genomic localization of estrogen receptor [alpha] (ER[alpha]) and JNK1 in basal and estrogen-stimulated MCF-7 breast cancer cells. I found that JNK1 binds to the promoter of many genes. ER[alpha] is required for the binding of JNK1 to the estrogen-induced sites, and JNK1 in turn functions as a coregulator of ER[alpha]. The convergence of ER[alpha] and JNK1 at target promoters regulates estrogen-dependent gene expression, as well as downstream estrogendependent cell growth responses. Furthermore, the implication of long noncoding RNAs (lncRNAs) in breast cancer is also coming to light. I developed a computational approach that integrates information from multiple genomic datasets, and generated a comprehensive catalog of 1888 expressed lncRNA genes in MCF-7 cells. Almost half of them are first annotated in this study, and more than a quarter are estrogen-regulated. Close examination revealed many interesting features. Interestingly, cell type-specific expression of lncRNAs predicts the intrinsic molecular subtypes of breast cancer, suggesting its potential utility as prognostic marker. Lastly, by selecting lncRNAs with elevated expression in breast tumors, and whose differential expression across a wide spectrum of tissues and cell types correlates with important cell viability genes, we identified a number of lncRNAs that are required for the normal growth of human breast cancer cells. Collectively, my studies expanded our understanding of the molecular mechanisms underlying breast cancer biology, and suggested new targets for therapeutic interventions.

Available in PDF, EPUB and Kindle. Book excerpt: The Ninth Annual Pezcoller Symposium entitled "The Biology of Tumors" was held in Rovereto, Italy, June 4-7, 1997. It focused on the genetic mechanisms underlying het erogeneity of tumor cell populations and tumor cell differentiation, on interactions be tween tumor cells and cells of host defenses, and the mechanisms of angiogenesis. With presentations at the cutting edge of progress and stimulating discussions, this symposium addressed issues related to phenomena concerned with cell regulation and cell interactions as determined by activated genes through the appropriate and timely media tion of gene products. Important methodologies that would allow scientists to measure dif ferentially genes and gene products and thus validate many of the mechanisms of control currently proposed were considered, as were the molecular basis of tumor recognition by the immune system, interactions between cells and molecular mechanisms of cell regula tion as they are affected by or implemented through these interactions. The molecular and cellular mechanisms of tumor vascularization were also discussed. It was recognized that angiogenesis provides a potential site of therapeutic intervention and this makes it even more important to understand the mechanisms underlying it. We wish to thank the participants in the symposium for their substantial contribu tions and their participation in the spirited discussions that followed. We would also like to thank Drs.

This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Breast Cancer: Cellular and Molecular Biology [Kluwer Academic Pub lishers, 1988], we tried to present an introduction to the emerging basic studies on steroid receptors, oncogenes, and growth factors in the regulation of normal and malignant mammary epithelium. The response to this volume was superb, indicating a tremendous interest in basic growth regulatory mechanisms governing breast cancer and controlling its malignant progres sion. In the two years since its publication, much new and exciting in formation has been published and the full interplay of regulatory mechanisms is now beginning to emerge. We have divided this book into four sections that we hope will unify important concepts and help to crystallize areas of consensus and/or disagreement among a diverse group of basic and clinical scientists working on the disease. The first section is devoted to studies on oncogenes, antioncogenes, proliferation, and tumor prognosis. The first chapter, by Sunderland and McGuire, introduces the characteristics of breast cancer as studied by patho logists to establish prognostic outcome. Of particular interest is a new proto oncogene called HER-2 (or neu), which is rapidly becoming accepted as a valuable new tumor marker of poor prognosis. The second chapter, by Lee Bookstein and Lee, introduces the best known antioncogene, the retinoblas toma antioncogene, whose expression is sometimes lost in breast cancer. Malignant progression appears to be influenced by the balance of proto oncogene and antioncogene expression.

Download or read book P270 AND THE SWI SNF Complex in Breast Cancer written by and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breast cancer arises from a series of harmful mutations to genes important for the normal regulation of cell growth and differentiation. Identification of the gene products whose loss is important in the development of the cancer is the primary means of determining who is at risk. There is an acute need for a more comprehensive understanding of the gene products that contribute to regulation, and the consequences of their failures. Gene products implicated in estrogen-responsive pathways are particularly likely to be significant in tumongenesis because exposure to estrogen is one of the most important contributory factors for the development of breast cancer. Our lab has cloned a new gene, p270, which codes for a protein that has structural characteristics and biochemical properties suggesting that it plays a significant role in the regulation of gene expression in response to estrogen. This project is designed to test this possibility by analyzing p270 expression and function in normal and breast cancer cells. This analysis will advance our understanding of the molecular mechanisms underlying normal breast development and carcinogenesis. These studies are likely to identify new markers for diagnosis and prognosis. They may ultimately lead to the design of therapeutic strategies based on the function of p270. These studies are particularly likely to open up new perspectives and stimulate new initiatives in the search for a cure for breast cancer.

Download or read book Genes Oncogenes and Hormones written by Robert B. Dickson and published by Springer Science & Business Media. This book was released on 1992-10-31 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where do you begin to look for a recent, authoritative article on the diagnosis or management of a particular malignancy? The few general oncology textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. Certain general journals frequently publish good in-depth reviews of cancer topics, and published symposium lectures are often the best overviews available. Unfortunately, these reviews and supplements appear sporadically, and the reader can never be sure when a topic of special interest will be covered. Cancer Treatment and Research is a series of authoritative volumes that aim to meet this need. It is an attempt to establish a critical mass of oncology literature covering virtually all oncology topics, revised frequently to keep the coverage up to date, and easily available on a single library shelf or by a single personal subscription. We have approached the problem in the following fashion: first, by dividing the oncology literature into specific subdivisions such as lung cancer, genitourinary cancer, pediatric oncology, etc.; and second, by asking eminent authorities in each of these areas to edit a volume on the specific topic on an annual or biannual basis. Each topic and tumor type is covered in a volume appearing frequently and predictably, discussing current di agnosis, staging, markers, all forms of treatment modalities, basic biology, and more.

Download or read book Cancer Biology How Science Works written by Carsten Carlberg and published by Springer Nature. This book was released on 2021-07-05 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer is a collection of diseases that can affect basically every organ of our body, all of which have in common uncontrolled cellular growth. The cells forming our body have the potential to grow in the context of wound healing or for the constant replacement of cells in our blood, skin or intestine. Behind every newly diagnosed malignant tumor in adulthood there is an individual history of probably 20 or more years of tumorigenesis. Therefore, malignant tumor formation often takes time making cancer in most cases to an aging-related disease that we seem not to be able to evade. However, tumorigenesis is dependent on multiple environmental influences, many of which we have under control by lifestyle decisions, such as retaining from smoking, selecting healthy food and being physically active. Thus, cancer preventive interventions are the most effective way to fight against cancer. This textbook wants not only to describe basic mechanisms leading to cancer but also to provide the readers with a more holistic view including cancer surveaillance mechanisms of the immune system. We will place these insights in the context of the personal consequences of everyone’s lifestyle decisions. The content of the book is linked to the lecture course in “Cancer Biology”, which is given by Prof. Carlberg since 2005 at the University of Eastern Finland in Kuopio. Moreover, biological processes explained in this book will be set into a clinical context using the experience of Dr. Velleuer in the daily care in oncology. This book also relates to the textbooks “Mechanisms of Gene Regulation: How Science Works” (ISBN 978-3-030-52321-3), “Human Epigenetics: How Science Works” (ISBN 978-3-030-22907-8) and “Nutrigenomics: How Science Works” (ISBN 978-3-030-36948-4), the studying of which may be interesting to readers who like to get more detailed information.

This book was released on 2024-01-11 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic scientific background Breast cancer is one of the most common cancer and the most frequent cause of cancer death among women worldwide. Currently, subtyping breast cancers into hormone receptor (HR) positive, human epidermal growth factor receptor-2 overexpressing (HER2+), and triple negative breast cancer (TNBC) is the basis of diagnosing and treating this disease. The main treatment strategies for breast cancer include surgery, endocrine therapy, molecular targeted therapy, chemotherapy, radiotherapy, immunotherapy and gene therapy. However, resistance of breast cancer cells to chemotherapeutic agents, molecular targeted therapies and immunotherapy may occur either intrinsically or de nova, and is often ultimately responsible for treatment failure. Therefore, drug resistance poses a major challenge to breast cancer treatment. Current developments: Drug resistance in breast cancer is a complex clinical condition originating from a wide range of molecular alterations. The development of endocrine therapy resistance is believed to be associated with many cellular changes, such as ESR1 gene mutations, bypassing estrogen signaling pathway and altered tamoxifen metabolism. Meanwhile, changes in immune response, alternation of drug-binding property and downstream pathways are involved in the mechanisms of drug resistance in HER2+ breast cancer. In addition, resistance to chemotherapeutic agents predominantly arises from increased drug efflux and cross resistance. Current studies suggest that treatment strategies and therapeutics have to be designed specifically to each patient in different clinical situations. The use of modern genomic, proteomic and functional analytical techniques has contributed to identify novel genes and signaling networks involved in breast cancer drug resistance. Moreover, the use of high-throughput techniques in combination with bioinformatics and systems biology approaches has aided the interrogation of clinical samples and allowed the identification of molecular signatures and genotypes that predict responses to certain drugs. Despite much progress has been made in the field of breast cancer drug resistance, such as combination therapy and drug-loaded nanoparticles, the complexity and variability of drug resistance mechanism still inevitably lead to the continuous occurrence of drug resistance. Therefore, with the increasing amounts of anti-breast cancer agents, there are now unprecedented opportunities to understand and overcome drug resistance through further research into mechanisms and corresponding strategies, which will help achieve lasting disease control and bring survival benefits to patients with advanced cancer. Papers of interest: The current Research Topic of Frontiers in Pharmacology focuses on publishing Original Research, Review articles and Case Reports focusing on (a) elucidating mechanisms of drug resistance in breast cancer, target mutations, tumor microenvironment, undiscovered genes and signaling pathways; (b) promising drug delivery systems that can enhance the sensitivity of anti- breast cancer agents to various tumors; (c) strategies that can improve patient care during bio-chemotherapeutic treatments; (d) small molecule compounds that are effective against drug-resistant breast tumors (e) biomarkers of chemotherapy resistance in breast cancer patients and (f) in vitro and in vivo models. Guidelines for article of submission: - Authors must stick to the set guidelines for ethical practices by the Frontiers journals. - The main content of the article must have certain innovation and research significance. - The authors should describe the construction method of drug-resistant cell lines when using them for experiments in the article.
