Melanoma (skin cancer) found to be easily prevented with low-cost Vitamin B-3

(Natural News) Researchers from the University of Sydney, Australia believe that nicotinamide (vitamin B3) can be used to prevent the incidence of melanoma, a deadly form of skin cancer. The study, published in Photodermatology, Photoimmunology, and Photomedicine, demonstrates the efficacy of vitamin B3 in reducing or even reversing DNA damage and inflammation caused by ultraviolet...

. Wondrak Metabolic reprogramming is a molecular hallmark of cancer. Recently, we have reported the overexpression of glyoxalase 1 (encoded by GLO1), a glutathione-dependent enzyme involved in detoxification of the reactive glycolytic byproduct methylglyoxal, in human malignant melanoma cell culture models and clinical samples. However, the specific role of GLO1 in melanomagenesis remains largely unexplored. Here, using genetic target modulation, we report the identification of GLO1 as a novel molecular determinant of invasion and metastasis in malignant melanoma. First, A375 human malignant melanoma cells with GLO1 de...

ckert Current treatments for metastatic cutaneous melanoma include immunotherapies and drugs targeting key molecules of the mitogen-activated protein kinase (MAPK) pathway, which is often activated by BRAF driver mutations. Overall responses from patients with metastatic BRAF mutant melanoma are better with therapies combining BRAF and mitogen-activated protein kinase kinase (MEK) inhibitors. However, most patients that initially respond to therapies develop drug resistance within months. Acquired resistance to targeted therapies can be due to additional genetic alterations in melanoma cells and to non-genetic events f...

Mutated IDH1/2 produces the metabolite 2-hydroxyglutarate (2HG), which interferes with epigenetic regulation of gene expression, and thus may promote tumorigenesis. Data for IDH1 inhibitors show that 30-40% of AML patients respond to monotherapy with a median duration of response of 8 mont...

Non-melanoma skin cancer (NMSC) is the most common cancer in fair-skinned adults and comprises basal-cell carcinoma (BCC) and squamous-cell carcinoma (SCC). Its incidence reaches 1/100 person-year in Australia (Lomas et al. 2012), and is still on the rise worldwide (Madan et al. 2010). Development of NMSC depends on genetic and environmental factors. Particularly, there is clear evidence that cumulative sun exposure contributes to the development of NMSC (Ananthaswamy et al. 1997; Madan et al. 2010).

Abstract Cutaneous metastases (CMs) signal the spread of a primary tumor to the skin and dermis, particularly in patients with melanoma or with breast, lung, or gastrointestinal cancers. Although these lesions may present as superficial and painless, some CMs may lead to ulceration, drainage, and discomfort, causing distress to patients. Oncology nurses require knowledge about the clinical presentation of CMs, including incidence, pathophysiology, diagnostic evaluation, and complex symptomatology, as well as standard treatment and care for patients. In addition, nurses can provide psychosocial interventions to ass...

AbstractSkin cancers remain the most common group of cancers globally, and the incidence continues to rise. Although localized skin cancers tend to have excellent outcomes following surgical excisions, the less common cases that become surgically unresectable or metastatic have been associated with poor prognosis and suboptimal treatment responses to cytotoxic chemotherapy. Development of monoclonal antibodies to programmed cell death-1 receptor and its ligand (PD-1/PD-L1) have transformed the management of metastatic melanoma, squamous cell carcinoma, and Merkel cell carcinoma. These agents, as monotherapies, are associat...
