Trio is a new kind of database system that supports data, uncertainty, and lineage in a fully integrated manner. The first Trio prototype, dubbed Trio-One, is built on top of a conventional DBMS...

Mesoscopic modeling for nucleic acid chain dynamics (2005)

Sales-Pardo, M., Guimera, R., Moreira, A. A., Widom, J., Amaral, L. A. N.

To gain a deeper insight into cellular processes such as transcription and translation, one needs to uncover the mechanisms controlling the configurational changes of nucleic acids. As a step toward...

Polymer reptation and nucleosome repositioning (2001)

Schiessel, H., Widom, J., Bruinsma, R. F., Gelbart, W. M.

We consider how beads can diffuse along a chain that wraps them, without becoming displaced from the chain; our proposed mechanism is analogous to the reptation of "stored length" in more familiar...

Protocols for Integrity Constraint Checking in Federated Databases (1997)

Widom, J.

A federated database is comprised of multiple interconnected database systems that primarily operate independently but cooperate to a certain extent. Global integrity constraints can be very useful...

Implementing Set-Oriented Production Rules as an Extension to Starburst (1991)

Widom, J., Lindsay, B.G., Cockrane, R.J.

This paper describes the implementation of a set-oriented database production rule language proposed in earlier papers. Our implementation uses the extensibility features of the Starburst database...

Nucleosome packaging and nucleosome positioning of genomic DNA

Lowary, P. T., Widom, J.

The goals of this study were to assess the extent to which bulk genomic DNA sequences contribute to their own packaging in nucleosomes and to reveal the relationship between nucleosome packaging and...

Twist constraints on linker DNA in the 30-nm chromatin fiber: implications for nucleosome phasing.

Yao, J, Lowary, P T, Widom, J

Previous work has shown that nucleosome repeat lengths, and hence linker DNA lengths, are preferentially quantized to a set of values differing by integral multiples of the helical twist of DNA. An...

A relationship between the helical twist of DNA and the ordered positioning of nucleosomes in all eukaryotic cells.

Widom, J

A large number of measurements of nucleosome repeat lengths are analyzed and are found to exhibit preferential quantization to a set of values related by integral multiples of the helical twist of...

Direct detection of linker DNA bending in defined-length oligomers of chromatin.

Yao, J, Lowary, P T, Widom, J

Linker DNA, which connects between nucleosomes in chromatin, is short and, therefore, may be essentially straight and inflexible. We have carried out hydrodynamic and electron microscopic studies of...

Effects of Histone Tail Domains on the Rate of Transcriptional Elongation through a Nucleosome

Protacio, R. U., Li, G., Lowary, P. T., Widom, J.

The N-terminal tail domains of the core histones play important roles in gene regulation, but the exact mechanisms through which they act are not known. Recent studies suggest that the tail domains...

Poly(dA-dT) Promoter Elements Increase the Equilibrium Accessibility of Nucleosomal DNA Target Sites

Anderson, J. D., Widom, J.

Polypurine tracts are important elements of eukaryotic promoters. They are believed to somehow destabilize chromatin, but the mechanism of their action is not known. We show that incorporating an A16...

Spontaneous Access of Proteins to Buried Nucleosomal DNA Target Sites Occurs via a Mechanism That Is Distinct from Nucleosome Translocation

Anderson, J. D., Thåström, A., Widom, J.

Intrinsic nucleosome dynamics termed “site exposure” provides spontaneous and cooperative access to buried regions of nucleosomal DNA in vitro. Two different mechanisms for site exposure have...

Effectiveness of natural and synthetic complexes of porin and O polysaccharide as vaccines against Brucella abortus in mice.

Winter, A J, Rowe, G E, Duncan, J R, Eis, M J, Widom, J, Ganem, B, ...

A single vaccination of mice with a complex of porin and smooth lipopolysaccharide (porin-S-LPS) extracted from virulent Brucella abortus 2308 provided significant protection (P less than 0.01 to P...

Higher-order structure of Saccharomyces cerevisiae chromatin.

Lowary, P T, Widom, J

We have developed a method for partially purifying chromatin from Saccharomyces cerevisiae (baker's yeast) to a level suitable for studies of its higher-order folding. This has required the use of...

DNA twisting flexibility and the formation of sharply looped protein–DNA complexes

Cloutier, T. E., Widom, J.

Gene-regulatory complexes often require that pairs of DNA-bound proteins interact by looping-out short (often ≈100-bp) stretches of DNA. The loops can vary in detailed length and sequence and,...

Higher-order structure of long repeat chromatin.

Widom, J, Finch, J T, Thomas, J O
