Available in PDF, EPUB and Kindle. Book excerpt: Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype that lacks estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) amplification. Thus, TNBC does not respond to traditional endocrine or HER2-targeted therapies, has a poor prognosis, and lacks effective targeted therapies. Some TNBC tumors express androgen receptor (AR) and may benefit from AR targeted therapies. However, the function of AR in TNBC and efficacy of new generation AR inhibitors are unknown. I hypothesized that AR supports proliferation, metastatic potential, and cancer stem-like cell (CSC) maintenance and that inhibition of AR will decrease tumor burden in preclinical models of breast cancer. My work demonstrates that AR exhibits nuclear expression in at least 22% of primary TNBC tumors. While AR is most abundant in the “luminal AR” (LAR) subtype, non-LAR molecular subtypes are also critically dependent on AR protein. Indeed, AR inhibition significantly reduces baseline proliferation, anchorage-independent growth, migration, and invasion and increases apoptosis in non-LAR molecular subtypes. In vivo, the AR antagonist Enzalutamide (Enza) significantly decreases viability of non-LAR xenografts. Furthermore, AR regulates amphiregulin, which partially rescues the effects of AR inhibition on proliferation, migration, and invasion. AR transcript, protein, and transcriptional activity increase in tumors cells in suspension culture compared to attached conditions suggesting that AR may also maintain CSCs. Indeed, AR inhibition decreases CSCs in vitro. In vivo, pre-treatment with Enza decreases the tumor-initiating capacity of TNBC cells in a limiting dilution assay. Breast CSCs are enriched following chemotherapy and may repopulate the tumor. Indeed, Enza significantly decreases tumor burden when administered during or after chemotherapy in vivo. In summary, AR supports proliferation, metastatic phenotypes, tumor initiating capacity and maintenance of CSCs. AR targeted therapies may represent the first effective targeted therapy for TNBC and greatly improve patient outcomes.

Book excerpt: Anoikis is defined broadly as apoptosis that is inhibited by appropriate cell-matrix interactions. Normal and tumor cells vary widely in their sensitivity to anoikis, but, in general, metastatic tumor cells are inevitably anoikis-resistant. In particular, tumor cells that possess a cancer stem cell or mesenchymal phenotype, arising from the oncogenic Epithelial-Mesenchymal Transition (EMT), are transcriptionally re-programmed to resist anoikis. While the anoikis response occurs through the mitochondrial pathway typically found in other apoptotic responses (e.g., DNA damage, death receptors, oxidative stress), the regulation of anoikis by cell-matrix signalling is unique and only partially characterized. The uniqueness of anoikis is: a. regulation by integrins, non-integrin matrix receptors, and the signaling complexes associated with them; b. regulation by metabolic changes occurring in response to attachment/detachment; c. regulation by oncogenes and tumor suppressor genes d. regulation by tumor microenvironment; e. regulation by EMT.

Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have highlighted that epithelial-mesenchymal transition (EMT) is not only about cell migration and invasion, but it can also govern many other important elements such as immunosuppression, metabolic reprogramming, senescence-associated secretory phenotype (SASP), stem cell properties, therapy resistance, and tumor microenvironment interactions. With the on-going debate about the requirement of EMT for cancer metastasis, an emerging focus on intermediate states of EMT and its reverse process mesenchymal-epithelial transition (MET) offer new ideas for metastatic requirements and the dynamics of EMT/MET during the entire metastatic cascade. Therefore, we would like to initiate discussions on viewing EMT and its downstream signaling networks as a fulcrum of cellular plasticity, and a facilitator of the adaptive responses of cancer cells to distant organ microenvironments and various therapeutic assaults. We hereby invite scientists who have prominently contributed to this field, and whose valuable insights have led to the appreciation of epithelial-mesenchymal plasticity as a more comprehensive mediator of the adaptive response of cancer cells, with huge implications in metastasis, drug resistance, tumor relapse, and patient survival.

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.
