High mobility group box 1 (HMGB1) is a cytokine with a key role in tissue regeneration and angiogenesis. Previous studies have shown that topical application of HMGB1 to skin wounds of mouse models of diabetes enhanced vessel density and accelerated wound healing, suggesting that diabetes may affect endogenous HMGB1 functions. Dipeptidyl peptidase IV(More)
UNLABELLED Recently developed proteomic technologies allow to profile thousands of proteins within a high-throughput approach towards biomarker discovery, although results are not as satisfactory as expected. In the present study we demonstrate that serum proteome denaturation is a key underestimated feature; in fact, a new differential denaturation(More)
The role of tissue transglutaminase (TG-2, TGase-2) in cancer development is still a fascinating field of research. The available reports do not elucidate fully its mechanism of action, due to the limitations of in vitro approaches. Therefore, to understand TG-2 role in cancer, we carried out an in vivo study with a more direct approach. TG-2 was in vivo(More)
In this study, we have evaluated the potential antineoplastic effects of α-mangostin (α-M), the most representative xanthone in Garcinia mangostana pericarp, on melanoma cell lines. This xanthone markedly inhibits the proliferation of high-metastatic B16-F10 melanoma cells. Furthermore, by deeply analyzing which steps in the metastatic process are(More)
Melanoma is the most aggressive skin-cancer, showing high mortality at advanced stages. Platelet Derived Growth Factor Receptor-alpha (PDGFR-alpha) potently inhibits melanoma- and endothelium-proliferation and its expression is significantly reduced in melanoma-biopsies, suggesting that melanoma progression eliminates cells expressing PDGFR-alpha. In the(More)
Migration is a key cellular function with important implications in cell physiology. Impairment of such function is observed in angiogenesis, cancer, central nervous system development, and many other physiological and pathological events. Serum is considered among the most potent physiological chemotactic stimuli. Transglutaminase 2 (TG2) is involved in(More)
