Regulation of cell death receptor S-nitrosylation and apoptotic signaling by Sorafenib in hepatoblastoma cells

Nitric oxide (NO) plays a relevant role during cell death regulation in tumor cells. The overexpression of nitric oxide synthase type III (NOS-3) induces oxidative and nitrosative stress, p53 and cell death receptor expression and apoptosis in hepatoblastoma cells. S-nitrosylation of cell death receptor modulates apoptosis. Sorafenib is the unique recommended molecular-targeted drug for the treatment of patients with advanced hepatocellular carcinoma. The present study was addressed to elucidate the potential role of NO during Sorafenib-induced cell death in HepG2 cells. We determined the intra- and extracellular NO concentration, cell death receptor expression and their S-nitrosylation modifications, and apoptotic signaling in Sorafenib-treated HepG2 cells. The effect of NO donors on above parameters has also been determined. Sorafenib induced apoptosis in HepG2 cells. However, low concentration of the drug (10nM) increased cell death receptor expression, as well as caspase-8 and -9 activation, but without activation of downstream apoptotic markers. In contrast, Sorafenib (10 µM) reduced upstream apoptotic parameters but increased caspase-3 activation and DNA fragmentation in HepG2 cells. The shift of cell death signaling pathway was associated with a reduction of S-nitrosylation of cell death receptors in Sorafenib-treated cells. The administration of NO donors increased S-nitrosylation of cell death receptors and overall induction of cell death markers in control and Sorafenib-treated cells. In conclusion, Sorafenib induced alteration of cell death receptor S-nitrosylation status which may have a relevant repercussion on cell death signaling in hepatoblastoma cells.Instituto de Salud Carlos III PI13/00021Ministerio de Economía y Competitividad BFU2012-32056Consejería de Economía, Innovación, Ciencia y Empleo, Junta de Andalucía BIO-0216Consejería de Economía, Innovación, Ciencia y Empleo, Junta de Andalucía CTS-6264Consejería de Salud, Junta de Andalucía PI13/ 0002

Post-Franco Theatre

In the multiple realms and layers that comprise the contemporary Spanish theatrical landscape, “crisis” would seem to be the word that most often lingers in the air, as though it were a common mantra, ready to roll off the tongue of so many theatre professionals with such enormous ease, and even enthusiasm, that one is prompted to wonder whether it might indeed be a miracle that the contemporary technological revolution – coupled with perpetual quandaries concerning public and private funding for the arts – had not by now brought an end to the evolution of the oldest of live arts, or, at the very least, an end to drama as we know it

Benito Pérez Galdós

In Galdós\u27 time, the tensions between such diverse phenomena as coins and credit, free trade and protectionist tariffs, factory work and domestic economy, masculine and feminine, and private and public exacerbated friction among peoples—those of pueblo and rural origins, whose voices rasped and whose bright colors raked the eye, and a nascent, insecure bourgeosie who, fearful of the masses, strove to imitate the aristocracy. Old and new converged also with the question of suffrage and citizenship to aggravate social malaise and political upheavals—Carlist wars, palace intrigues, the Revolution of 1868 and overthrow of Queen Isabel, the brief reign of Amadeo of Savoy, the aborted First Republic and the Bourbon Restoration (1875-1885), which reached Spain from England in the imported person of Alfonso XII. These turbulent events undergird the cultural, historical, and political events of the novels by Benito Pérez Galdós (1843–1920) to be discussed in this chapter. Galdós is the author of seventy-seven novels, twenty-six original plays, and numerous occasional pieces, written between 1867 and 1920. These divide into two main categories: the historical and the contemporary social novels, now more appropriately described as novels of modernity The forty-six historical novels, called Episodios nacionales, make up five series, each consisting of ten interconnected novels, except the fifth series, left unfinished. The thirty-one novels of modernity, published between 1870 and 1915, also divide into two groups: Novelas de la primera época ( Novels of the Early Period, 1870–1879) and Las novelas de la serie contemporánea ( The Contemporary Social Novels, 1881–1915). The novels of the early period comprise Galdós\u27 first attempts at novel writing, as well as four so-called thesis novels : Doña Perfecta (1876), the sequel Gloria (1876–1877), Marianela (1878), and La familia de León Roch ( The Family of León Roch, 1878–1879). The next group of novels represents what Galdós called his segunda manera —his second style, a different kind of writing ... a more sophisticated and varied mode of narrative presentation
