Abstract
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) may represent the quintessential example of a moonlighting protein. The latter are a new, intriguing class of cell proteins which exhibit multiple activities in different subcellular locales apart from their initially, well-characterized function. As such, apart from its classical role in energy production, membrane-bound GAPDH is required for membrane fusion, endocytosis and, intriguingly, for iron transport. Cytoplasmic GAPDH regulates mRNA stability and is required for ER to Golgi trafficking. Nuclear GAPDH is involved in apoptosis, transcriptional gene regulation, the maintenance of DNA integrity, as well as nuclear tRNA export. Paradoxically, the etiology of a number of human pathologies is dependent upon GAPDH structure and function. In particular, recent evidence indicates a significant role for moonlighting GAPDH in tumorigenesis. Specifically, these include its role in the survival of tumor cells, in tumor angiogenesis, as well as its control of tumor cell gene expression and posttranscriptional regulation of tumor cell mRNA. Each of these activities correlates with increased tumor progression and, unfortunately, a poor prognosis for the afflicted individual.

Abstract
The importance of mitochondria as oxygen sensors as well as producers of ATP and reactive oxygen species (ROS) has recently become a focal point of cancer research. However, in the case of melanoma, little information is available to what extent cellular bioenergetics processes contribute to the progression of the disease and related to it, whether oxidative phosphorylation (OXPHOS) has a prominent role in advanced melanoma. In this study we demonstrate that compared to melanocytes, metastatic melanoma cells have elevated levels of OXPHOS. Furthermore, treating metastatic melanoma cells with the drug, Elesclomol, which induces cancer cell apoptosis through oxidative stress, we document by way of stable isotope labeling with amino acids in cell culture (SILAC) that proteins participating in OXPHOS are downregulated. We also provide evidence that melanoma cells with high levels of glycolysis are more resistant to Elesclomol. We further show that Elesclomol upregulates hypoxia inducible factor 1-α (HIF-1α), and that prolonged exposure of melanoma cells to this drug leads to selection of melanoma cells with high levels of glycolysis. Taken together, our findings suggest that molecular targeting of OXPHOS may have efficacy for advanced melanoma.
