Book excerpt: The primary physiological role of estrogens is the development of secondary sexual characteristics including development and function of the normal breast, reproductive system, bone homeostasis, cognitive functions and cardiovascular system. Estrogen has also been implicated as a major player in the progression of normal breast epithelial tissue to a carcinoma. The role of estrogens in breast cancer has been studied extensively and mainly attributed to the transcriptional activation of growth genes through the estrogen receptor. Along with activation of genes, estrogen is also responsible for repression of many genes. Anti-estrogens antagonize both gene activation and gene repression by estrogen. However, the significance and physiological relevance of gene repression by estrogen is poorly understood. mRNA profiling of MCF-7 breast cancer cells combined with a detailed gene ontology analysis revealed that the genes repressed by estrogen are mostly involved in tumor progression including invasion, drug resistance, angiogenesis and immune evasion. This study looks at the mechanism and impact of estrogen in repressing these tumor progression genes in breast cancer cells; we found that estrogen suppresses the invasiveness of breast cancer cells in a manner that is antagonized by anti-estrogens and is independent of HER2 status. These studies have implications in understanding the incidence of invasive breast cancer following hormone replacement therapy and long term anti-estrogen treatment and may also aid in the development of superior drugs for adjuvant treatment in breast cancer. Variability in response to chemotherapeutic drugs among patients is a longstanding issue in the treatment of several cancers. Likewise, in advanced lung cancer, patient response to the recently introduced drug, pemetrexed is variable. Pemetrexed is an antifolate approved for the first-line treatment of advanced non-squamous non-small cell lung cancer. Dexamethasone was added to the treatment regimen with pemetrexed to alleviate the serious side effect of severe skin rash observed in many patients. Dexamethasone is administered to patients the day before, the day of and the day after pemetrexed chemotherapy. We show that treatment of non-squamous non-small cell lung cancer cell line models with dexamethasone causes a reduction in the S-phase fraction of cells along with a decrease in the expression of thymidylate synthase and dihydrofolate reductase, which are primary and secondary targets of pemetrexed, respectively. As a consequence of these effects of dexamethasone pemetrexed cytotoxicity is attenuated. The response to dexamethasone is variable among different cell line models. Our correlative and functional studies demonstrate that the variability in pemetrexed sensitivity is causally related to variability in the expression of the glucocorticoid receptor isoform alpha, i.e. cells with relatively lower expression of the receptor fail to respond to dexamethasone and hence are sensitive to pemetrexed. These results could help to predict response to pemetrexed therapy leading to the development of individualized treatment strategies.

Available in PDF, EPUB and Kindle. Book excerpt: Breast and prostate cancers are both hormone-dependent, at least in some stages of their progression. Hormonal manipulation represents an important therapeutic approach. Although most of breast and prostate cancers initially respond to hormone therapy, most tumors reinitiate to growth. Finally, hormone-resistant and metastatic breast and prostate cancers may develop. Thus, the challenge is the dissection of mechanisms by which steroid receptor signaling pathways continue to influence cell growth and invasiveness. Compelling evidence indicates that steroid hormones elicit non-genomic responses in extra-nuclear compartment of target cells. In this cellular location, steroid-coupled receptors rapidly recruit signaling effectors or scaffold proteins and activate multiple pathways leading to proliferation, survival, migration and invasiveness. The immediate challenge is the dissection of key events regulating the steroid response of target tissues to prevent progression and improve treatment of breast and prostate cancers.

Available in PDF, EPUB and Kindle. Book excerpt: This volume provides comprehensive coverage of the current knowledge of the physiology of the endocrine system and hormone synthesis and release, transport, and action at the molecular and cellular levels. It presents essential as well as in-depth information of value to both medical students and specialists in Endocrinology, Gynecology, Pediatrics, and Internal Medicine. Although it is well established that the endocrine system regulates essential functions involved in growth, reproduction, and homeostasis, it is increasingly being recognized that this complex regulatory system comprises not only hormones secreted by the classic endocrine glands but also hormones and regulatory factors produced by many organs, and involves extensive crosstalk with the neural and immune system. At the same time, our knowledge of the molecular basis of hormone action has greatly improved. Understanding this complexity of endocrine physiology is crucial to prevent endocrine disorders, to improve the sensitivity of our diagnostic tools, and to provide the rationale for pharmacological, immunological, or genetic interventions. It is such understanding that this book is designed to foster.

Book excerpt: Though overall cancer incidence and mortality have continued to decline in recent years, cancer continues to devastate the lives of far too many Americans. In 2009 alone, 1.5 million American men, women, and children were diagnosed with cancer, and 562,000 died from the disease. There is a growing body of evidence linking environmental exposures to cancer. The Pres. Cancer Panel dedicated its 2008¿2009 activities to examining the impact of environmental factors on cancer risk. The Panel considered industrial, occupational, and agricultural exposures as well as exposures related to medical practice, military activities, modern lifestyles, and natural sources. This report presents the Panel¿s recommend. to mitigate or eliminate these barriers. Illus.

This book was released on 2012-12-06 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite recent advances in adjuvant therapies of cancer, the regi mens of postoperative adjuvant chemotherapy treatment which are presently available fail to cure the majority of cancer patients. Pre operative (neoadjuvant) chemotherapy represents a new approach in drug scheduling, based on sound theoretical, pharmacokinetic, and experimental principles. The preoperative timing of chemotherapy before definitive sur gery is not a minor change in the therapy of cancer. To be successful, large numbers of practitioners and their patients must participate. Substantial alterations of many aspects of the present management of cancer will have to follow. Therefore, before such therapy can be fully and routinely implemented, results of the novel treatment and its rationale have to be carefully evaluated. In preoperative treatment, other features will likely gain impor tance. For the first time, clinicians have a chance to follow the in vivo response of the tumor exposed to preoperative chemotherapy. The subsequent histological assessment of the tumor sample may likely become an important prognostic guide, permitting more re fined individual approaches to the planning of postoperative adju vant treatment. The value of such a treatment strategy can already be appreciated in the clinical setting, as seen from the therapy of osteosarcoma. Furthermore, preoperative chemotherapy might render previously inoperable tumors operable and hence resectable with a curative intention. The preoperative reduction of tumor bulk may also effectively decrease the need for more radical operations, permitting a more uniform adoption of conservative surgery.
