Fluctuations in biological and bioinspired electron-transfer reactions
(2010)Central to theories of electron transfer (ET) is the idea that nuclear motion generates a transition state that enables electron flow to proceed, but nuclear motion also induces fluctuations in the donor-acceptor (DA) ...

Free energy simulations come of age: Protein-ligand recognition
(2002)In recent years, molecular dynamics simulations of biomolecular free energy differences have benefited from significant methodological advances and increased computer power. Applications to molecular recognition provide ...

Free energy simulations: The meaning of the individual contributions from a component analysis
(1994)A theoretical analysis is made of the decomposition into contributions from individual interactions of the free energy calculated by thermodynamic integration. It is demonstrated that such a decomposition, often referred ...

Genetic evidence for a trans-heterozygous model for cystogenesis in autosomal dominant polycystic kidney disease
(2000)Polycystic kidney disease (ADPKD) is a condition with an autosomal dominant mode of inheritance and adult onset. Two forms of the disease, ADPKD1 and ADPKD2, caused by mutations in PKD1 and PKD2, respectively, are very ...

Genotype-renal function correlation in type 2 autosomal dominant polycystic kidney disease
(2003)Autosomal dominant polycystic kidney disease (ADPKD) is a common Mendelian disorder that affects approximately 1 in 1000 live births. Mutations of two genes, PKD1 and PKD2, account for the disease in approximately 80 to ...

In vivo, site-specific, covalent conjugation of quantum dots to proteins via split-intein splicing
(2012)The ability to target proteins with nanostructures and/or nanodevices in vivo is important for understanding and controlling their biological function. Quantum dots (QDs) serve as an ideal model nanostructure due to their ...

Insulin-mimetic action of vanadium compounds on osteoblast-like cells in culture
(1997)Vanadium compounds mimic insulin actions in different cell types. The present study concerns the insulin-like effects of three vanadium(V) derivatives and one vanadium(IV) complex on osteoblast-like (UMR106 and MC3T3E1) ...

Intein-mediated site-specific conjugation of Quantum Dots to proteins in vivo
(2009)We describe an intein based method to site-specifically conjugate Quantum Dots (QDs) to target proteins in vivo. This approach allows the covalent conjugation of any nanostructure and/or nanodevice to any protein and thus ...

Investigation of the stability of polyelectrolyte multilayer coatings in open-tubular capillary electrochromatography using laser scanning confocal microscopy
(2005)A simple polyelectrolyte multilayer (PEM) coating procedure was used for the development of stable modified capillaries. PEM coatings were constructed in fused-silica capillaries using alternating rinses of cationic and ...

Loss of heterozygosity in polycystic kidney disease with a missense mutation in the repeated region of PKD1
(1998)Loss of heterozygosity (LOH) is a molecular phenomenon that denotes the loss of one of the two alleles at a specific locus. It is frequently associated with tumour suppressor genes in various cancers and also with ...

Medullary cystic kidney disease with hyperuricemia and gout in a large Cypriot family: No allelism with nephronophthisis type 1
(1998)We describe a large Cypriot family with an interstitial type of nephropathy, inherited as an autosomal dominant trait that led to end stage renal failure between 51 to 78 years of age (mean 62.2 years). Twenty-three people ...

Molecular optimization using computational multi-objective methods
(2007)Improving the profile of a molecule for the drug-discovery process requires the simultaneous optimization of numerous, often competing objectives. Traditionally, standard chemo-informatics methods ignored this problem and ...

Non-isotopic RNase cleavage assay for mutation detection in MEFV, the gene responsible for familial Mediterranean fever, in a cohort of Greek patients
(2004)Background: The MEFV gene is responsible for familial Mediterranean fever (FMF). Several disease associated mutations have been identified. The range of genetic variation in MEFV in Greek patients has not been determined. ...

Novel PKD1 deletions and missense variants in a cohort of Hellenic polycystic kidney disease families
(2001)The autosomal dominant form of polycystic kidney disease is a very frequent genetically heterogeneous inherited condition affecting approximately 1: 1000 individuals of the Caucasian population. The main symptom is the ...

Pathways, pathway tubes, pathway docking, and propagators in electron transfer proteins
(1995)The simplest views of long-range electron transfer utilize flat one-dimensional barrier tunneling models, neglecting structural details of the protein medium. The pathway model of protein electron transfer reintroduces ...

Article
PKD2, a gene for polycystic kidney disease that encodes an integral membrane protein
(1996)A second gene for autosomal dominant polycystic kidney disease was identified by positional cloning. Nonsense mutations in this gene (PKD2) segregated with the disease in three PKD2 families. The predicted 968-amino acid ...

Polarized distribution of Bcr-Abl in migrating myeloid cells and co-localization of Bcr-Abl and its target proteins
(1999)Bcr-Abl plays a critical role in the pathogenesis of Philadelphia chromosome-positive leukemia. Although a large number of substrates and interacting proteins of Bcr-Abl have been identified, it remains unclear whether ...

The Polycomb Group Protein SUZ12 regulates histone H3 lysine 9 methylation and HP1α distribution
(2007)Regulation of histone methylation is critical for proper gene expression and chromosome function. Suppressor of Zeste 12 (SUZ12) is a requisite member of the EED/EZH2 histone methyltransferase complexes, and is required ...

Predicting the acid/base behavior of proteins: A constant-pH monte carlo approach with generalized born solvent
(2010)The acid/base properties of proteins are essential in biochemistry, and proton binding is a valuable reporter on electrostatic interactions. We propose a constant-pH Monte Carlo strategy to compute protonation free energies ...

Prenatal diagnosis of aneuploidy using artificial neural networks in relation to health economics
(Springer Verlag, 2016)The early detection of fetal chromosomal abnormalities such as aneuploidies, has been an important subject in medicine over the last thirty years. A pregnant woman is advised by the doctor to perform an amniocentesis test, ...
