The literature on apoptosis has grown tremendously in recent years, and the mechanisms that are involved in this programmed cell death pathway have been enlightened. It is now known that apoptosis takes place starting from early development to adult stage for the homeostasis of multicellular organisms, during disease development and in response to different(More)
Cancer cells frequently exhibit gross chromosomal alterations such as translocations, deletions, or gene amplifications an important source of chromosomal instability in malignant cells. One of the better-documented examples is the formation of anaphase bridges-chromosomes pulled in opposite directions by the spindle apparatus. Anaphase bridges are(More)
The Fas/Fas Ligand (FasL) system and survivin have counteracting roles in cell survival. Therefore, we explored the role of circulating soluble Fas (sFas) and the tissue levels of Fas and survivin with regard to response to chemotherapy in lung cancer patients. Serum samples from 52 lung cancer patients and 54 control subjects (19 benign lung disease and 35(More)
Aortic aneurysm is a complex multifactorial disease, and its molecular mechanism is not understood. In thoracic aortic aneurysm (TAA), the expansion of the aortic wall is lead by extracellular matrix (ECM) degeneration in the medial layer, which leads to weakening of the aortic wall. This dilatation may end in rupture and-if untreated-death. The aortic(More)
Aortic aneurysms (AA) are characterized by structural deterioration leading to progressive dilation. During the development of AA, two key structural changes are pronounced, one being degradation of extracellular matrix and the other loss of smooth muscle cells (SMCs) through apoptosis. Reactive oxygen species (ROS) are produced above physiological levels(More)
Having the correct number of centrosomes is crucial for proper chromosome segregation during cell division and for the prevention of aneuploidy, a hallmark of many cancer cells. Several recent studies (Basto et al., 2008; Kwon et al., 2008; Yang et al., 2008) reveal the importance of mechanisms that protect against the consequences of harboring too many(More)
Metal based chemotherapeutic drugs are widely used as an effective method to defeat various cancers. In this study, the mechanism of action of a novel therapeutic agent, [Pd(sac)(terpy)](sac)·4H2O (sac = saccharinate, and terpy = 2,2':6',2″-terpyridine) was studied. To better understand the proteomic changes in response to this agent, we performed nano(More)
Oxysterols, oxygenated derivatives of cholesterol, are found abundantly in the plasma and atherosclerotic plaques, a common risk factor for thoracic aortic aneurysms (TAAs). Among the oxysterols, namely 7-ketocholesterol (7-KC) and 25-hydroxycholesterol (25-OHC), lead both to induction of reactive oxygen species (ROS) in cells and to apoptosis in smooth(More)
Metal-based compounds represent promising anticancer therapeutic agents. In this study, the mechanism of action of a novel metal-based drug, a palladium(II) (Pd) complex ([PdCl(terpy)](sac)·2H2O, terpy=2,2':6',2''-terpyridine and sac=saccharinate), was elucidated. The tested compound induced cytotoxicity in nine different human cancer cell lines that(More)
The outcome in patients with breast cancer is not satisfactory to date, although new chemotherapy regimens have been introduced in clinics. Therefore, novel approaches are required for better management of patients with breast cancer. In this study, we tested the cytotoxic activity of a new combination of fenretinide, a synthetic retinoid, with(More)
