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.

This book was released on 2012-11-08 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprehensively covers recent prrogress in breast cancer research. In an effort to successfully treat breast cancer, it is imperative to a) fully understand the disease with all its heterogeneity, b) understand the factors that influence the metastasis of breast cancer to distant organs making it lethal and c) understand the underlying processes that lead to the phenomenon of drug-resistance making the disease particularly incurable. The book explores all of these issues, including the phenomenon of epithelial-mesenchymal-transition, cancer stem cells as well as microRNAs in an attempt to better understand the disease in connection to its heterogeneity/metastasis/drug-resistance as well as to propose novel signaling pathways for therapeutic intervention. The profiling of tumors to molecularly classify breast cancers is also investigated so that customized targeted therapies can be developed.

Book Synopsis Multi-Drug Resistance in Cancer by : Rishabha Malviya
Download or read book Multi-Drug Resistance in Cancer written by Rishabha Malviya and published by John Wiley & Sons. This book was released on 2023-07-18 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: MULTI-DRUG RESISTANCE IN CANCER The book details the mechanisms underlying multi-drug cellular resistance and the targets of novel chemotherapeutic agents. Cancer is a major killer all over the world. Even with all the progress made, chemotherapy is still the mainstay of modern cancer treatment. The progression of the cellular defeat of numerous independent anticancer drugs in terms of their chemical structure is a major barrier to successful chemotherapy. Multi-drug resistance (MDR) is a term for the fact that most cancer patients exhibit this phenomenon. According to the numbers, drug resistance carries the blame for 90% of cancer patient deaths. Refractory cancer and tumor recurrence are common outcomes of prolonged chemotherapy. Because of the prevalence of drug-resistance mutations, the difficulty of treating tumors increases and the therapeutic efficacy of drugs decreases. Multi-Drug Resistance in Cancer: Mechanism and Treatment Strategies contains nine chapters that cover topics such as: studying the mechanics of resistance to drugs by autophagy; studies to delineate the role of efflux transporters; expression of drug transporters; resistance to targeted therapies in breast cancer; advances in metallodrug driven combination treatment for cancer; and use of natural agents for the overcoming of cancer drug resistance. The book aims to provide the latest data on the mechanisms of cellular resistance to anticancer agents currently used in clinical treatment. It provides a better understanding of the mechanisms of MDR and targets of novel chemotherapy agents which should guide future research concerning new effective strategies in cancer treatment. Audience This book is written for pharmaceutical and biomedical scientists and researchers at both the bench and in the clinic who are interested in the mechanisms and strategies for overcoming cancer’s multi-drug resistance.
Book Synopsis Molecular Mechanism of Lymph Node Metastasis in Breast Cancer by :
Download or read book Molecular Mechanism of Lymph Node Metastasis in Breast Cancer written by and published by . This book was released on 2009 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many challenges exist in the current management of metastatic breast cancer as there are fewer recognized therapeutic strategies. Therefore, a better understanding of the molecular events in the metastatic process is critical. Several reports have described correlation of hyaluronan (HA) with initiation and progression of various types of epithelial cancers. The HA synthase (HAS) isoforms encode the enzymes that produce and deposit HA while the hyaluronidase (HYAL) genes code for enzymes that degrade HA and their expression is dysregulated in various tumors as a result of transcriptional and epigenetic changes that accompany progression. In this report, we examined the expression of HAS1, HAS2 and HAS3, HYAL1 and HYAL2 and LYVE1 in mammary tumor cell with different metastatic potential (4T1, highly metastatic; Cl66, moderately metastatic; Cl66M2, low metastatic). We observed increased expression of HAS1, HAS2 and HAS3 as well as HAYL 1 and HAYL2 in aggressive mammary tumor cells. Next we stably knocked-down HAS2 and HAS3 expression and overexpressed LYVE1 in 4T1 cells and analyzed cell proliferation, migration, tumor growth and metastasis. We observed that Has2/Has3 knock-down and LYVE1 overexpression modulated mammry tumor growth and spontaneous metastasis. Together, these data demonstrate an important role of HAS2 and LYVE1 in mammary tumor growth, angiogenesis, invasion, and metastasis.

Book Synopsis Molecular Mechanisms of Metastasis Suppression in Human Breast Cancer by :
Download or read book Molecular Mechanisms of Metastasis Suppression in Human Breast Cancer written by and published by . This book was released on 2000 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our preliminary data indicated the presence of a breast carcinoma metastasis suppressor genes on human chromosome 11. The goal was to identify and begin characterizing the gene(s) responsible. Two approaches were proposed - (1) introduction of smaller pieces of chromosome 11 into cells with assessment of metastatic potential; and (2) identification of differentially expressed mRNA in metastasis suppressed cells. Progress using Approach #1 was not successful. Approach #2 was successful. We identified three novel cDNAs using differential display which were more highly expressed in the metastasis-suppressed neo11/435 hybrids. Moreover, one of those candidates, BRMS1, significantly suppressed metastasis in two human breast carcinoma cell lines when transfected and constitutively expressed. BRMS1 1 maps to 11q13, a site commonly involved in late-stage breast carcinoma. The mechanism of action appears to be novel, but was not determined during the funding period. In summary, we accomplished the stated ultimate objective for DAMD-17-96-1-6152. Results generated from DAMD-17- 96-1-6152 were used to successfully compete for funding from the National Cancer Institute to follow-up on these exciting findings.

Book Synopsis Multi-Drug Resistance in Cancer by : Jun Zhou
Download or read book Multi-Drug Resistance in Cancer written by Jun Zhou and published by Humana Press. This book was released on 2012-08-09 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemotherapy is one of the major treatment options for cancer patients; however, the efficacy of chemotherapeutic management of cancer is severely limited by multidrug resistance, in that cancer cells become simultaneously resistant to many structurally and mechanistically unrelated drugs. In the past three decades, a number of mechanisms by which cancer cells acquire multidrug resistance have been discovered. In addition, the development of agents or strategies to overcome resistance has been the subject of intense study. This book contains comprehensive and up-to-date reviews of multidrug resistance mechanisms, from over-expression of ATP-binding cassette drug transporters such as P-glycoprotein, multidrug resistance-associated proteins, and breast cancer resistance p- tein to the drug ratio-dependent antagonism and the paradigm of cancer stem cells. The book also includes strategies to overcome multidrug resistance, from the development of compounds that inhibit drug transporter function to the modulation of transporter expression. In addition, this book contains techniques for the detection and imaging of drug transporters, methods for the investigation of drug resistance in animal models, and strategies to evaluate the efficacy of resistance reversal agents. The book intends to provide a state-of-the-art collection of reviews and methods for both basic and clinician investigators who are interested in cancer multidrug resistance mechanisms and reversal strategies.

Book Synopsis Radiation Responses of Chemoresistant Adenocarcinoma Cells by : Lidiya Luzhna
Download or read book Radiation Responses of Chemoresistant Adenocarcinoma Cells written by Lidiya Luzhna and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Breast cancer is a major cause of cancer-related death among women throughout the world. Treatment of breast cancer often fails due to the development of resistance to both chemo- and radiotherapy. The aim of this study was to analyze and compare the response to radiation of MCF-7 breast adenocarcinoma cells and MCF-7 cells that are resistant to doxorubicin (MCF-7/DOX). The results presented in this thesis show that drug-resistant MCF-7/DOX cells survive high doses of radiation exposure better than MCF-7 cells. Moreover, the chemo- and radioresistance of MCF-7/DOX cells share common molecular mechanisms and loss of sensitivity to radiation in chemo-resistant cells may be explained by alterations in their DNA methylation profile. The results of experiments presented in this thesis may, therefore, serve as a first step for future analysis of tumour resistance to radio- and chemotherapy and for the development of novel epigenetic strategies for reversal of breast cancer resistance to cytotoxic treatment regimens.
Book Synopsis Characterizing a Role for the LncRNA BORG During Breast Cancer Progression and Metastasis by : Alex Joseph Gooding
Download or read book Characterizing a Role for the LncRNA BORG During Breast Cancer Progression and Metastasis written by Alex Joseph Gooding and published by . This book was released on 2018 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breast cancer is the most common malignancy and second most common cause of cancer-related death in women, a clinical challenge exasperated by the lack of targeted therapies for metastasis, the most deadly component of breast cancer. Although the molecular mechanisms underpinning the dissemination of primary breast cancer cells to distant tissues remain incompletely understood, long noncoding RNAs (lncRNAs) have emerged as potent regulators of breast cancer development and progression, including the metastatic spread of disease.Through in silico and biological analyses, we identified a novel lncRNA, BMP/OP-Responsive Gene (BORG), whose expression directly correlates with aggressive breast cancer phenotypes, as well as with metastatic competence and disease recurrence in multiple clinical breast cancer patient cohorts. Mechanistically, BORG elicits the metastatic outgrowth of latent breast cancer cells by promoting the localization and transcriptional repressive activity of TRIM28, which binds BORG and induces substantial alterations in carcinoma proliferation and survival. Moreover, inhibiting BORG expression in metastatic breast cancer cells impedes their metastatic colonization of the lungs of mice, implying that BORG acts as a novel driver of the genetic and epigenetic alterations that underlie the acquisition of metastatic and recurrent phenotypes by breast cancer cells.Interestingly, the BORG-dependent transcriptome demonstrates enhanced signaling through survival and viability pathways, as well as decreased activation of cell death pathways. Accordingly, we determined that BORG expression is broadly promoted by environmental and chemotherapeutic stresses, a transcriptional response that facilitates the survival of breast cancer cells. These effects rely upon a BORG-induced induction of NF- B signaling as part of a feed-forward NF- B signaling loop, as well as its ability to bind and activate RPA1.Taken together, our mechanistic insights into BORG-mediated metastasis and chemoresistance offer the foundation necessary to develop therapies that target the molecular drivers vital to metastatic outgrowth of disseminated breast cancer cells, particularly those persisting in a dormant state.
