For many years, extracellular matrix (ECM) was considered to function as a tissue support and filler. However, we now know that ECM proteins control many cellular events through their interaction with cell-surface receptors and cytoplasmic signaling pathways. For example, they regulate cell proliferation, cell division, cell adhesion, cell migration, and apoptosis. We focus in this review on a laminin isoform, laminin-332 (for Read More

Atherosclerosis is an inflammatory disease. Monocyte-platelet interactions may play a key role in this process by various pathways. They “inflame” each other as well as adjacent cell types at the vascular wall by direct physical interactions, autocrine and paracrine activation processes. These processes promote monocyte recruitment (in)to the vascular wall - a key mechanism in atherogenesis. This article highlights the molecu Read More

Human contains 49 ATP-binding cassette (ABC) transporter genes and the multidrug resistance associated proteins (MRP1/ABCC1, MRP2/ABCC2, MRP3/ABCC3, MRP4/ABCC4, MRP5/ABCC5, MRP6/ABCC6, MRP7/ABCC10, MRP8/ABCC11 and MRP9/ABCC12) belong to the ABCC family which contains 13 members. ABCC7 is cystic fibrosis transmembrane conductance regulator; ABCC8 and ABCC9 are the sulfonylurea receptor Read More

Computational chemistry software for lead discovery has become well established in pharmaceutical industry and has found its way to the desktop computers of medicinal chemists for different purposes, providing insight on the mode of action and binding properties, and creating new ideas for lead structure refinement. In this review we investigate the performance and reliability of recent state-of-the-art data modeling techniq Read More

Renal failure, both acute and chronic, represents an important health problem by its social, sanitary and economic aspects. Mitogen-activated protein kinases (MAPK) are a family of mediators involved in the transduction of extracellular stimuli to intracellular responses. The best studied members of this family are extracellular signal-regulated kinases 1 and 2 (ERK1 and ERK2), Jun NH2-terminal kinase (JNK), p38 kinase a Read More

It is now recognized that necrosis is not the only mechanism responsible for chemically-induced cell death. It is believed that apoptosis could be the major form of cell death induced by toxicants and that necrosis is associated only with circumstances of gross cell injury. The liver is a key target organ for drug toxicity and an important effort in drugdiscovery deals with the identification of molecules with hepatotoxic potential. The Read More
