'Imatinib dose escalation has been suggested as an effective therapy for advanced gastrointestinal stromal tumors (GIST) after progression on the standard dose. We evaluated the efficacy, tolerability, and pharmacokinetics of imatinib dose escalation. Eighty-four patients with GIST who received imatinib 800 mg/day as second-line therapy were reviewed. In 66 patients, imatinib ... More
Use of cell-SELEX to generate DNA aptamers as molecular probes of HPV-associated cervical cancer cells.

PubMed ID:22536456
'Disease-specific biomarkers are an important tool for the timely and effective management of pathological conditions, including determination of susceptibility, diagnosis, and monitoring efficacy of preventive or therapeutic strategies. Aptamers, comprising single-stranded or double-stranded DNA or RNA, can serve as biomarkers of disease or biological states. Aptamers can bind to specific ... More
A streamlined method for detecting structural variants in cancer genomes by short read paired-end sequencing.
Authors:Mijuškovic M, Brown SM, Tang Z, Lindsay CR, Efstathiadis E, Deriano L, Roth DB
Journal:PLoS One
PubMed ID:23144753
Defining the architecture of a specific cancer genome, including its structural variants, is essential for understanding tumor biology, mechanisms of oncogenesis, and for designing effective personalized therapies. Short read paired-end sequencing is currently the most sensitive method for detecting somatic mutations that arise during tumor development. However, mapping structural variants ... More
Two CRISPR-Cas systems in Methanosarcina mazei strain Gö1 display common processing features despite belonging to different types I and III.

Journal:RNA Biol
PubMed ID:23619576
The clustered regularly interspaced short palindromic repeats (CRISPR) system represents a highly adaptive and heritable defense system against foreign nucleic acids in bacteria and archaea. We analyzed the two CRISPR-Cas systems in Methanosarcina mazei strain Gö1. Although belonging to different subtypes (I-B and III-B), the leaders and repeats of both ... More
Camphor pathway redux: functional recombinant expression of 2,5- and 3,6-diketocamphane monooxygenases of Pseudomonas putida ATCC 17453 with their cognate flavin reductase catalyzing Baeyer-Villiger reactions.

PubMed ID:23524667
Whereas the biochemical properties of the monooxygenase components that catalyze the oxidation of 2,5-diketocamphane and 3,6-diketocamphane (2,5-DKCMO and 3,6-DKCMO, respectively) in the initial catabolic steps of (+) and (-) isomeric forms of camphor (CAM) metabolism in Pseudomonas putida ATCC 17453 are relatively well characterized, the actual identity of the flavin ...
