Bcl-2 family on guard at the ER
Samali, Afshin; Sanjeev, Gupta; Ní Chonghaile, Tríona; MacDonald, David C; Szegezdi, Eva (American Physiological Society, 2009)The endoplasmic reticulum (ER) is the main site for protein folding, lipid biosynthesis and calcium storage in the cell. Disturbances of these critical cellular functions lead to ER stress. The ER responds to disturbances ... -
Decorated macrocycles via ring-closing double-reductive amination. Identification of an apoptosis inducer of leukemic cells that at least partially antagonizes a 5-HT2 receptor
Zhou, Jian; Reidy, Mairead; O'Reilly, Ciaran; Jarikote, Dilip V.; Negi, Arvind; Samali, Afshin; Szegezdi, Eva; Murphy, Paul V. (American Chemical Society, 2015-03-16)A build-couple-pair strategy, including double-reductive amination macrocyclization, has been used to generate decorated macrocycles (eannaphanes) with an embedded triazole and monosaccharide. Biological screening led to ... -
Kinetics in signal transduction pathways involving promiscuous oligomerizing receptors can be determined by receptor specificity: Apoptosis induction by TRAIL
Szegezdi, Eva; Mahalingam, Devalingam (American Society for Biochemistry and Molecular Biology, 2012)Here we show by computer modeling that kinetics and outcome of signal transduction in case of hetero-oligomerizing receptors of a promiscuous ligand largely depend on the relative amounts of its receptors. Promiscuous ... -
Mechanisms of ER Stress-Mediated Mitochondrial Membrane Permeabilization
Gupta, Sanjeev; Cuffe, Lorraine; Szegezdi, Eva; Logue, Susan E.; Neary, Catherine; Healy, Sandra; Samali, Afshin (2010)During apoptosis, the process of mitochondrial outer membrane permeabilization (MOMP) represents a point-of-no-return as it commits the cell to death. Here we have assessed the role of caspases, Bcl-2 family members and ... -
The Proteasome Inhibitor Bortezomib Sensitizes AML with Myelomonocytic Differentiation to TRAIL Mediated Apoptosis
van Dijk, Marianne; Murphy, Eoin; Morrell, Ruth; O'Dwyer, Michael; Szegezdi, Eva; Samali, Afshin (2011)Acute myeloid leukemia (AML) is an aggressive stem cell malignancy that is difficult to treat. There are limitations to the current treatment regimes especially after disease relapse, and therefore new therapeutic agents ... -
Rapid and efficient cancer cell killing mediated by high-affinity death receptor homotrimerizing TRAIL variants
Natoni, Alessandro; Szegezdi, Eva; Samali, Afshin (Macmillan Publishers Limited, 2010)The tumour necrosis factor family member TNF-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in a variety of cancer cells through the activation of death receptors 4 (DR4) and 5 (DR5) and is considered ...
