Proteins and disease

Proteomics is a valuable new technology used in the development of novel and more effective drugs following the identification and characterization of disease-causing proteins. Proteins also provide useful molecular markers for the diagnosis of specific diseases. In essence, proteomics provides the link between genes, proteins, and diseases and complements the information obtained by genomics. [Pg.542]

Hydroxymethyl-6-methyluracil (1043) was prepared many years ago from 6-methyl-uracil and formaldehyde, or in other ways. Since 1956 it has received much attention in the USSR under the (transliterated) name pentoxyl or pentoxil. It is used in several anaemic and disease conditions. For example, a mixture of folic acid and pentoxyl quickly reduces the anaemia resulting from lead poisoning pentoxyl stimulates the supply of serum protein after massive blood loss it stimulates wound healing it stimulates the immune response in typhus infection and it potentiates the action of sulfonamides in pneumococcus infections (70MI21300). [Pg.154]

The separation of proteins and peptides mixtures is the objective of protein biochemisdy. Albumin (Mr 66 000) concentration in a biological fluid (seaim, urine or cerebrbrospinal fluid) is assayed as markers for a series disease, such as nephritic syndrome or chronic glomuleronephritis. In diabetic patients the progression of microalbuminuria is accompanied by an increase in urinary concentrations of human semm albumen. In normal the excretion of albumin is 20 (tg/ml, in pathology - 20-200 p.g/ml. [Pg.100]

Several chemical compounds may cause inflammation or constriction of the blood vessel wall (vasoconstriction). Ergot alkaloids at high doses cause constriction and thickening of the vessel wall. Allylamine may also induce constriction of coronary arteries, thickening of their smooth muscle walls, and a disease state that corresponds to coronary heart disease. The culprit is a toxic reactive metabolite of allylamine, acrolein, that binds covalently to nucleophilic groups of proteins and nucleic acids in the cardiac myocytes. [Pg.297]

FIGURE 1.25 The virus life cycle. Viruses are mobile bits of genetic iuformatiou encapsulated in a protein coat. The genetic material can be either DNA or RNA. Once this genetic material gains entry to its host cell, it takes over the host machinery for macromolecular synthesis and subverts it to the synthesis of viral-specific nucleic acids and proteins. These virus components are then assembled into mature virus particles that are released from the cell. Often, this parasitic cycle of virus infection leads to cell death and disease. [Pg.31]

Viruses are small infectious agents composed of a nucleic acid genome (DNA or RNA) encased by structural proteins and in some cases a lipid envelope. They are the causative agents of a number of human infectious diseases, the most important for public health today being acquired immunodeficiency syndrome (AIDS), hepatitis, influenza, measles, and vituses causing diarrhoea (e.g., rotavirus). In addition, certain viruses contribute to the development of cancer. Antiviral drugs inhibit viral replication by specifically targeting viral enzymes or functions and are used to treat specific virus-associated diseases. [Pg.196]

Pasteurella multocida toxin (PMT) is the major pathogenic factor responsible for atrophic rhinitis, a disease which is characterized by bone loss in the nose of pigs. PMT is a 145 kDa single-chain exotoxin, which activates Goq protein (but not Gan) and stimulates phospholipase C 3. In addition, G12/i3 proteins and subsequently Rho pathways are activated. [Pg.247]

A number of different low molecular weight compounds are known to stablize proteins in their native conformation and, therefore, may be effective in correcting of protein folding abnormalities in vivo. Relevant compounds are iV-acetyl-L-lysine, L-camitine, taurine, betaine, ectoine, and hydroxy-ectoine [4]. Some of these chemical chaperones and pharmacological chaperones are already used in clinical trials to combat protein folding diseases, such as cystic fibrosis. [Pg.350]

Genetic disorders of HDL metabolism have also resulted in greater understanding of the molecular regulation of HDL metabolism. Nonsense or missense mutations in apoA-I can result in substantially reduced HDL-C levels due to rapid catabolism of structurally abnormal or truncated apoA-I proteins. Tangier disease is a rare autosomal codominant disorder characterized by markedly low HDL-C and apoA-I levels and caused... [Pg.698]

PARs are coupled to multiple G-proteins and mediate a number of well-defined cellular responses via classical second messenger and kinase pathways. PARs are differentially expressed in cells of the vasculature as well in the brain, lung, gastrointestinal tract, skin as well as other highly vascularised tissues and evidence suggests distinct physiological functions and roles in disease states [2]. [Pg.1020]

Transgenic animals are genetically engineered animals, which allow the functional assessment of specific genes or proteins in health and disease. [Pg.1233]

Fatal hereditary disorder that typically presents in the neonatal period. Clinical features include an array of hepatic, renal and neurological dysfunctions. Patients with Zellweger syndrome rarely survive the first year of life. The disease is caused by mutations in the Pex proteins leading to an defective import of peroxisomal matrix proteins and consequently to a loss of most peroxisomal metabolic pathways. [Pg.1483]
