Available in PDF, EPUB and Kindle. Book excerpt: Antiestrogens and selective estrogen receptor modulators (SERMs) such as tamoxifen are effective in controlling the progression of estrogen receptor (ER)- positive breast tumors to more invasive phenotypes. However, over time, many patients acquire resistance to tamoxifen. The mechanisms underlying tamoxifen resistance remain elusive. Proline-, glutamic acid-, and leucine-rich protein-1) (PELP1) is a novel ER coactivator that plays a role in both genomic and nongenomic actions of ER. PELP1 is predominantly localized in the nucleus in hormonally responsive tissues, but recent studies suggest that PELP1 may be exclusively localized in the cytoplasm in cancer cells. We found that MCF-7 cells engineered to specifically express PELP1 in the cytoplasm (PELP1-cyto), exhibited hypersensitivity to estrogen but resistance to tamoxifen. In addition, PELP1-cyto cells exhibited increased association of PELP1 with Src, enhanced MAPK activation, and constitutive stimulation of AKT. Altered localization of PELP1 was sufficient to trigger PELP1's interaction with the p85 subunit of P13 kinase and P13 activation. Consistent with these findings, human tumors expressing PELP1'S in the cytoplasm showed increased AKT activation. Our results suggest that altered localization of coactivators such as PELP1'S promotes resistance to hormonal therapy, presumably via stimulation of nongenomic estrogen responses such as activation of MAPK and AKT.

Book excerpt: Breast Cancer - From Biology to Medicine thoroughly examines breast cancer from basic definitions, to cellular and molecular biology, to diagnosis and treatment. This book also has some additional focus on preclinical and clinical results in diagnosis and treatment of breast cancer. The book begins with introduction on epidemiology and pathophysiology of breast cancer in Section 1. In Section 2, the subsequent chapters introduce molecular and cellular biology of breast cancer with some particular signaling pathways, the gene expression, as well as the gene methylation and genomic imprinting, especially the existence of breast cancer stem cells. In Section 3, some new diagnostic methods and updated therapies from surgery, chemotherapy, hormone therapy, immunotherapy, radiotherapy, and some complementary therapies are discussed. This book provides a succinct yet comprehensive overview of breast cancer for advanced students, graduate students, and researchers as well as those working with breast cancer in a clinical setting.

Book Synopsis Tumorigenesis Research Advances by : David K. Wong
Download or read book Tumorigenesis Research Advances written by David K. Wong and published by Nova Publishers. This book was released on 2007 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tumourigenesis is the formation of tumours in the body, often caused by oncogenes. These tumours are the result of uncontrollable reproduction (cell division) due to alterations in the cell's genetic code, creating lesions in the tissue where they reside. Tumourigenesis can be divided into tumour initiation, promotion and progression. Oncogenomics often studies tumours caused by such a condition in hope of pinpointing genes -- pieces of genetic information -- that are susceptible to being changed (mutated) by external factors like ultraviolet light, toxic chemicals, and other carcinogens. The range of normal genetic alterations that a person's DNA undergoes over time is extraordinarily large, so it is hard to detect exactly what cause tumourigenesis. This book presents the latest research advances in the field.

Book Synopsis Estrogen Receptor and Breast Cancer by : Xiaoting Zhang
Download or read book Estrogen Receptor and Breast Cancer written by Xiaoting Zhang and published by Humana Press. This book was released on 2019-11-08 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of ER by Dr. Elwood Jensen exactly 60 years ago has not only led to the birth of a whole new vital nuclear receptor research field but also made a rapid, direct and lasting impact on the treatment and prevention of breast cancer. Since that landmark discovery, tremendous progress has been made in our understanding of the molecular functions of ER and development of targeted therapies against ER pathways for breast cancer treatment. However, there is currently no book available addressing these discoveries and recent advancement in a historical and systematic fashion. This book is intended to provide comprehensive, most up-to-date information on the history and recent advancement of ER and breast cancer by world renowned leaders in the field. These chapters include the history of the discovery of ER; physiological and pathological roles of ER; recent discovery of ER cistrome, transcriptome and its regulation of noncoding RNAs such as microRNAs and enhancer RNAs in breast cancer; development and clinical practices of the first targeted therapy Tamoxifen and other antiestrogens for breast cancer treatment; structural basis of ER and antiestrogen actions; molecular insights into endocrine resistance; the role of ER mutants, ER-beta and environmental estrogens in breast cancer; and emerging state-of-the-art therapeutic approaches currently in development to overcome treatment resistance and future perspectives. The book will provide undergraduate and graduate students, basic scientists and clinical cancer researchers, residents, fellows, as well as clinicians, oncology educators and the general public a thorough and authoritative review of these exciting topics.

Book Synopsis Therapeutic Resistance to Anti-hormonal Drugs in Breast Cancer by : Stephen Hiscox
Download or read book Therapeutic Resistance to Anti-hormonal Drugs in Breast Cancer written by Stephen Hiscox and published by Springer Science & Business Media. This book was released on 2009-01-11 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main causes of failure in the treatment of breast cancer is the intrinsic presence of, or development of, drug resistance by the cancer cells. Recent studies on the mechanisms of cancer drug resistance have yielded important information highlighting both how tumour cells may escape these therapeutic constraints and that drug resistance may further impinge on tumour cell functions that may ultimately promote an adverse cell phenotype. New targets have been identified with potential therapeutic applications in resistant breast cancer leading to the subsequent evaluation of inhibitors of these targets in preclinical studies. Importantly, there is increasing evidence from such studies demonstrating the benefit of novel combination strategies as potential avenues for future drug regimens. Written by experts in the subject area, this book covers the molecular details and functional consequences of endocrine resistance in breast cancer with particular emphasis on the future applications of novel drug combinations that may be utilized to circumvent resistance and improve anti-tumour effects. This book represents a timely publication in the field of breast cancer research, providing current knowledge in the area of drug resistance and will be important reading material for clinicians and researchers alike.
