Sanguinarine is a natural isoquinoline alkaloid derived from the root of Sanguinaria canadensis and from other poppy fumaria species, and is known to have a broad spectrum of pharmacological properties. Here we have found that sanguinarine, at low micromolar concentrations, showed a remarkably rapid killing activity against human melanoma cells. Time-lapse videomicroscopy showed rapid morphological changes compatible with an apoptotic cell death, which was further supported by biochemical markers, including caspase activation, poly(ADP-ribose) polymerase (PARP) cleavage and DNA breakdown. Pan-caspase inhibition blocked sanguinarine-induced cell death. Sanguinarine treatment also induced an increase in intracellular calcium concentration, which was inhibited by dantrolene, and promoted cleavage of BAP-31, thus suggesting a putative role for Ca2+ release from endoplasmic reticulum and a cross-talk between endoplasmic reticulum and mitochondria in the anti-melanoma action of sanguinarine. Sanguinarine disrupted the mitochondrial transmembrane potential (ΔΨm), released cytochrome c and Smac/DIABLO from mitochondria to cytosol, and induced oxidative stress. Overexpression of Bcl-XL by gene transfer did not prevent sanguinarine-mediated cell death, oxidative stress or release of mitochondrial apoptogenic proteins. However, preincubation with N-acetyl-l-cysteine (NAC) prevented sanguinarine-induced oxidative stress, PARP cleavage, release of apoptogenic mitochondrial proteins, and cell death. Pretreatment with glutathione (GSH) also inhibited the anti-melanoma activity of sanguinarine. Thus, pretreatment with the thiol antioxidants NAC and GSH abrogated the killing activity of sanguinarine. Taking together, our data indicate that sanguinarine is a very rapid inducer of human melanoma caspase-dependent cell death that is mediated by oxidative stress. © 2013 Elsevier B.V. ; This work was supported by grants from Fundação para a Ciência e a Tecnologia (FCT) (PTDC/QUI-QUI/101409/2008 and PEst-C/SAU/LA0001/2011 co-funded by Feder/Compete/National Funds) to P.J.O.; Ministerio de Economía y Competitividad of Spain (SAF2008-02251, SAF2011-30518), Red Temática de Investigación Cooperativa en Cáncer, Instituto de Salud Carlos III, cofunded by the Fondo Europeo de Desarrollo Regional of the European Union (RD06/0020/1037 and RD12/0036/0065) to F.M.; Fondo de Investigación Sanitaria and European Commission (PS09/01915) to C.G.; Junta de Castilla y León (CSI052A11-2, CSI221A12-2, GR15-Experimental Therapeutics and Translational Oncology Program, and Biomedicine Project 2010-2011) to F.M and C.G.

Being derived from the convoluted tubules of nephron, renal pelvis, ureters, bladder and urethra, urine-derived stem cells (UDSC) have a similar phenotype to mesenchymal stroma cells (MSC) and can be reprogrammed into iPSC (induced pluripotent stem cells). Having simple, safer, low-cost and noninvasive collection procedures, the interest in UDSC has been growing in the last decade. With great potential in regenerative medicine applications, UDSC can also be used as biological models for pharmacology and toxicology tests. This review describes UDSC biological characteristics and differentiation potential and their possible use, including the potential of UDSC-derived iPSC to be used in drug discovery and toxicology, as well as in regenerative medicine. Being a new cellular platform amenable to noninvasive collection for disease stratification and personalized therapy could be a future application for UDSC. ; publishersversion ; published

Triterpenoids are a large class of naturally occurring compounds, and some potentially interesting as anticancer agents have been found to target mitochondria. The objective of the present work was to investigate the mechanisms of mitochondrial toxicity induced by novel dimethylaminopyridine (DMAP) derivatives of pentacyclic triterpenes, which were previously shown to inhibit the growth of melanoma cells in vitro. MCF-7, Hs 578T and BJ cell lines, as well as isolated hepatic mitochondria, were used to investigate direct mitochondrial effects. On isolated mitochondrial hepatic fractions, respiratory parameters, mitochondrial transmembrane electric potential, induction of the mitochondrial permeability transition (MPT) pore and ion transport-dependent osmotic swelling were measured. Our results indicate that the DMAP triterpenoid derivatives lead to fragmentation and depolarization of the mitochondrial network in situ, and to inhibition of uncoupled respiration, induction of the permeability transition pore and depolarization of isolated hepatic mitochondria. The results show that mitochondrial toxicity is an important component of the biological interaction of DMAP derivatives, which can explain the effects observed in cancer cells. ; This work was supported by projects Pest-C/SAU/LA0001/2013– 2014 and PTDC/QUI-QUI/101409/2008 funded by Fundação para a Ciência e a Tecnologia (FCT), Portugal, and cofinanced by: 'COMPETE- Programa Operacional Factores de Competitividade', QREN and European Union (FEDER-Fundo Europeu de Desenvolvimento Regional).
