Rapid emergence of hepatitis C virus protease inhibitor resistance is expected

Description: Approximately 170 million people worldwide are infected with hepatitis C virus (HCV). Current therapy, consisting of pegylated interferon (PEG-IFN) and ribavirin (RBV), leads to sustained viral elimination in only about 45% of patients treated. Telaprevir (VX-950), a novel HCV NS3-4A serine protease inhibitor, has demonstrated substantial antiviral activity in patients with chronic hepatitis C genotype 1 infection. However, some patients experience viral breakthrough during dosing, with drug re… more

High quality copy number and genotype data from FFPE samples using Molecular Inversion Probe (MIP) microarrays

Description: A major challenge facing DNA copy number (CN) studies of tumors is that most banked samples with extensive clinical follow-up information are Formalin-Fixed Paraffin Embedded (FFPE). DNA from FFPE samples generally underperforms or suffers high failure rates compared to fresh frozen samples because of DNA degradation and cross-linking during FFPE fixation and processing. As FFPE protocols may vary widely between labs and samples may be stored for decades at room temperature, an ideal FFPE CN te… more

Genomic analysis of the symbiotic marine crenarchaeon, Cenarchaeumsymbiosum

Description: Crenarchaea are ubiquitous and abundant microbial constituents of soils, sediments, lakes and ocean waters, yet relatively little is known about their fundamental evolutionary, ecological, and physiological properties. To better describe the ubiquitous nonthermophilic Crenarchaea, we analyzed the genome sequence of one representative, the uncultivated sponge symbiont, Cenarchaeum symbiosum. C. symbiosum genotypes coinhabiting the same host partitioned into two dominant populations, correspondin… more

Functional genomics, an integrated approach. Final report for the Trieste component

Description: Phage display offers the possibility of selecting polypeptides (and the genes which encode them) from libraries of 10 billion or more different polypeptides on the basis of their abilities to bind target proteins and subdomains. The general principle of phage display relies on the coupling of phenotype and genotype in the phage. The specific aims of this project were threefold: (1) to produce a large phagemid antibody library; (2) to develop a general method for deriving antibodies against the … more

Characterization of chemically modified hyperthermophilic enzymes for chemical syntheses and bioremediation reactions. 1998 annual progress report

Description: 'Remediation processes frequently involve species possessing limited solubility in water. The authors are interested in novel strategies that use molecularly-engineered enzymes with enhanced activity and stability for the remediation of recalcitrant compounds in organic media. Organic biocatalysis may be motivated by the nature of the substrate itself, or by augmented mass transport, ease of product recovery, or novel reaction pathways afforded by the organic solvent. However, naturally-occurri… more

Characterization of chemically modified enzymes for bioremediation-reactions. 1997 annual progress report

Description: 'Many, if not most, biological transformation reactions of interest to US Department of Energy (DOE) site remediation involve substrates that are only sparingly soluble in aqueous environments. Hence, destruction of these recalcitrant and toxic materials would benefit tremendously if their degradation could be performed in nonaqueous environments. Organic biocatalysis may be motivated by the nature of the substrate itself, augmented mass transport, ease of product recovery, or novel reaction pa… more

A novel biomarker for beryllium sensitization in humans. 1998 annual progress report

Description: 'Beryllium reactive T-lymphocytes can be used as an indicator of sensitization. Traditionally, their presence is detected by an in vitro proliferation assay. However, this test is capricious (results varying from day to day in the same laboratory) and insensitive (rarely positive before clinical symptoms ). The objective of this project is to obtain and characterize beryllium reactive T-cells from peripheral blood using the hprt T-cell mutation assay. T-cells are selected on the basis of their … more

A novel biomarker for beryllium sensitization in humans. 1997 annual progress report

Description: 'Overall, this project is designed to identify the beryllium reactive T-cell clones that are proliferating in vivo in individuals sensitized to beryllium. The basic method for identifying such clones is the hprt T-cell mutation assay. The rationale is that in vivo proliferating T-lymphocytes are more likely to undergo hprt mutations and/or be included in hprt mutant fractions of T-cells isolated from peripheral blood. T-lymphocytes isolated as hprt mutants from beryllium sensitized individuals … more

Putting Tumors in Context

Description: The interactions between cancer cells and their micro- and macroenvironment create a context that promotes tumor growth and protects it from immune attack. The functional association of cancer cells with their surrounding tissues forms a new 'organ' that changes as malignancy progresses. Investigation of this process might provide new insights into the mechanisms of tumorigenesis and could also lead to new therapeutic targets. Under normal conditions, ORGANS are made up of TISSUES that exchange… more

Genetic characterization of Lophopyrum elongatum salt tolerance and associated ion regulation as expressed in bread wheat. Final technical report

Description: Lophopyrum elongatum is a highly salt-tolerant relative of wheat. Its salt tolerance is partially expressed in the amphiploid from a cross between wheat cv. Chinese Spring and L. elongatum. Genetic studies showed that the tolerance of gradually imposed salt stress is controlled by L. elongatum chromosomes 3E, 4E, 5E, and 7E and the tolerance of suddenly imposed salt stress by chromosomes 3E, 5E, 6E, and 7E. In wheat, rye, barley, and Dasypyrum, chromosomes of the same homoeologous groups, 3, 5,… more

Mechanisms and genetic control of interspecific crossing barriers in Lycopersicon. Final report

Description: Deficiency of Lycopersicon esculentum allele (E) was observed from the RFLP and isozyme data of the F{sub 2} populations derived from the cross L. esculentum x L. pennellii. The genome composition of the F{sub 2} populations containing L. pennellii cytoplasm (F{sub 2}{sup Lp4}) has a lower proportion of the homozygous L. pennellii (PP) genotypes and a higher proportion of heterozygote (EP) genotypes than that of the F{sub 2} populations containing L. esculentum cytoplasm (F{sub 2}{sup Le}).

A theoretical analysis of population genetics of plants on restored habitats

Description: Seed and propagules used for habitat restoration are not likely to be closely adapted to local site conditions. Rapid changes of genotypes frequencies on local microsites and/or microevolution would allow plants to become better adapted to a site. These same factors would help to maintain genetic diversity and ensure the survival of small endangered populations. The authors used population genetics models to examine the selection of genotypes during establishment on restored sites. Vegetative s… more
