Purpose Caspases are common mediators of cell death. Evasion death including apoptosis considered to be hallmarks cancer. A deeper understanding the apoptotic cascade may aid improving cancer therapies. Our aim was characterize progression following UV-induced genotoxic injury in a defined culture model.Materials and methods Hela cells were UV-irradiated with doses ranging from 0.1 60 mJ/cm2. C...

objective we have previously shown that rose bengal (rb) alone, not as a photosensitiser, could induce apoptotic- and non-apoptotic cell death in different melanoma cell lines. to clarify rb-induced toxicity mechanisms, role of caspases and reactive oxygen specious (ros) were studied in melanoma cells. material and methods human melanoma cell lines, me 4405 and sk-mel-28 were cultured in dmem m...

U ncontrolled lymphoproliferation is a characteristic feature of lymphomas and leukemias. Nonmalignant lym-phoproliferative diseases are also observed in humans as well as in lpr (lymphoproliferation) and gld (generalized lymphad-enopathy) mice. The discoveries that spontaneous mutations of Fas (APO-1/CD95) or its ligand (FasL) were associated with the lpr and gld phenotypes led to a satisfying...

Apoptosis is a conserved cell-death process displaying characteristic morphological and molecular changes including activation of caspase proteases. Recent work challenges the accepted roles of these proteases. New investigations in mice and the nematode Caenorhabditis elegans suggest that there could be caspase-independent pathways leading to cell death. In addition, another type of cell death...

Abstract Background Apoptosis is an important process for organism’s innate immune system to respond pathogens, while also allowing cell differentiation and other essential life functions. Caspases are one of the key protease enzymes involved in apoptotic process, however there currently a very limited understanding bivalve caspase diversity function. Results In this work, we investigated prese...
