Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases which are involved in the proteolytic processing of several components of the extracellular matrix. As a consequence, MMPs are implicated in several physiological and pathological processes, like skeletal growth and remodelling, wound healing, cancer, arthritis, and multiple sclerosis, raising a very widespread interest toward this class of e Read More

Pre-eclampsia (PE), a characteristic hypertensive disorder of human pregnancy and a leading cause of maternal and fetal mortality and morbidity worldwide, shares some similarities with atherosclerosis, namely the involvement of oxidative stress and of endothelial dysfunction in their pathophysiologies, the presence of similar typical lesions and of common risk factors. Although it is widely accepted that regular physica Read More

Literature publications reporting the development of organophosphorus compounds, targeting aspects of signal transduction to the titled therapeutic ends, are reviewed. With respect to extracellular targets, the development of ligands to purinergic (P2), and endothelial differentiation-gene receptors (of S1P- and LPA-receptor subtypes) is charted, along with inhibitors of the production and release of tumour necrosis fa Read More

Scientific interest in defining the human body's ability to limit the effects of administered drugs and xenobiotics dates from the mid-19th century when developing knowledge and techniques in the field of organic chemistry first made such studies possible. The first experimental evidence documenting the existence of cytochrome p450 (CYP) dates to the year 1955, when an enzyme system capable of oxidizing xenobiotic c Read More

Epidemiological studies show that high density lipoprotein cholesterol (HDL-C) levels are inversely related to the risk of vascular events. Statins are the most widely prescribed drugs for the treatment of dyslipidaemias and their use for the prevention of vascular events is evidence based. Statins raise HDL-C but this effect seems to vary considerably between studies. We searched the literature to assess the relationship between st Read More

The liver plays a central role in the regulation of cholesterol homeostasis. Hepatic cholesterol content is maintained by a complex interplay between input and output pathways; alterations in the balance among these processes may lead to accumulation of excess cholesterol in body compartments with potentially deleterious consequences at the level of blood vessels (atherosclerosis) and biliary tract (gallstone diseas Read More

Characterization of liver-specific autoantigens has given a fresh impetus to research in the pathogenesis of autoimmune liver diseases, viral-triggered and drug-induced autoimmunity affecting the liver. Intriguing is the fact that most of the liver-specific autoantigens are enzymes of key importance for cell's homeostasis. Detection of autoantibodies against the respective antigens is carried out for diagnostic and research Read More

Arsenic, a known human carcinogen, can induce tumors of the skin, urinary bladder, liver and lung etc.. On the other hand, arsenic is also a novel promising anticancer agent, and can be used effectively to treat acute promyelocytic leukemia (APL) and some other tumors. These paradoxical effects of arsenic not only result from direct or indirect influences on the genetic and epigenetic levels, but are also closely correlated wi Read More
