Abstract

The development and treatment of cancer presents a complex interaction between tumor and host. Provision of nutrients not only enables the maintenance of nutritional status, but also provides substrates and signals for immunity, tumor metabolism and protection of the host from treatment toxicities. Fat is one dietary element that has been explored for its role in cancer development. While the bulk of these studies have been observational or experimental, the evidence assembled suggests that dietary lipids behave uniquely to prevent or promote cancers. An additional aspect of cancer development is the role of adipose tissue as a source of, and a responder to, inflammatory signals that may be involved in tumor development. This Special Issue of Nutrients focuses on fat and cancer. The contributors to this Special Issue are well-recognized leaders in the field of cancer and have unique areas of focus including metabolism, immunology, biochemistry, epidemiology and nutrition. Each contribution highlights the latest research in these areas and what is known about fat and cancer with topics ranging from diet and cancer prevention, mechanisms of n-3 fatty acids on tumor development and the role of adipose tissue in cancer development and progression.

Abstract

Human cancers frequently arise from exposure to chemicals, although radiation, oxidation, and genetic factors play critical roles as well. DNA damage by these agents in a cell is an important first step in the process of carcinogenesis. DNA repair processes have evolved to repair these damages. However, the replication of damaged DNA may occur frequently prior to repair, resulting in gene mutations and the generation of altered proteins. Mutations in an oncogene, a tumor-suppressor gene, or a gene that controls the cell cycle give rise to a clonal cell population with an advantage in proliferation. The complex process of carcinogenesis includes many such events, but has been generally considered to be comprised of the three main stages known as initiation, promotion, and progression, which ultimately give rise to the induction of human cancer. The articles published in this book entitled “Chemically-Induced DNA Damage, Mutagenesis, and Cancer” provide an overview on the topic of the “consequence of DNA damage” in the context of human cancer with their challenges and highlights.

Abstract

Dear Colleagues, Malignant tumors develop distant metastases, e.g., small clusters of cells that detach from the primitive site and colonize distant organs and tissues. Unlike the primary masses, metastases are often difficult to fully eradicate by surgery ablation and are almost always the primary object of chemo- and/or immune-therapies. The presence of metastases at tumor diagnosis is responsible for the unfavorable prognosis and of relapses even after initially successful tumor therapies. The lack of success of chemo- and immune-therapy approaches depends on many factors among which, the inadequate capacity of the anti-tumor drugs of reaching appropriate concentrations in the organs and tissues involved in the metastatic growth is a major concern. Another factor is the complexity of the metastasis biology and of their molecular behavior, evidencing a population of tumor cells with a genetic compartment different from that of the tumor of origin. The involvement of host cells and factors recruited by the metastatic cells and committed to support the metastatic growth is also an event crucial for the lack of success of the anti-tumor therapy. The knowledge of the molecular biology of metastases is mandatory to support the search for chemical agents to treat the metastatic determinants and to control of the neoplastic disease. This Special Issue on “Chemical and Molecular Approach to Tumor Metastases” will explore the impact of biology, molecular medicine and chemistry on all aspects related to tumor metastases from the biological and molecular aspects of the metastatic growth, including the relationships between the metastatic cells and the host environment, and the search for druggable determinants useful for the chemical analysis of agents selectively active against tumor metastases. With the combination of invited reviews and original papers from prominent scientists working on all aspects of molecular medicine and cancer therapy, such as, but not limited to: drug delivery, genomics, chemoprevention, drug discovery, we aim to sample recent progress in molecular and chemical aspects of therapy of malignant tumors. Clinical success studies and evidences of novel compounds are particularly welcome.

Abstract

This Special Issue focuses on recent research on the important emerging and neglected tropical diseases (NTDs) in South and South East Asia and Northern Australia. This region stretches from Afghanistan in the west to Papua New Guinea in the east, and includes the Indian subcontinent, mainland South-East Asia (Indo China), maritime South East Asia, and the tropical regions of Australia. Many of these areas are highly endemic for important NTDs and emerging infectious diseases including lymphatic filariasis, leprosy, soil-transmitted helminthiases (hookworm, Trichuris, Ascaris, and Strongyloides), food-borne trematodiases, schistosomiasis, dengue/chikungunya/zika, leptospirosis, meloidosis, scabies, trachoma, and yaws. Several of these diseases are targeted for elimination or enhanced control by the World Health Organization in the next 5 to 10 years, although some have chronic lasting sequelae needing lifelong management. Control methods used include preventive chemotherapy, enhanced screening and treatment, intensified disease management, vector control, interruption of human to animal transmission, environmental/sanitation improvements and disability prevention/mitigation.
