Cholesteryl ester transfer protein (CETP) shuttles various lipids between lipoproteins, resulting in the net transfer of cholesteryl esters from atheroprotective, high-density lipoproteins (HDL) to atherogenic, lower-density species. Inhibition of CETP raises HDL cholesterol and may potentially be used to treat cardiovascular disease. Here we describe the(More)
Anaplastic lymphoma kinase gene (ALK) fusions have been identified in approximately 5% of non-small-cell lung carcinomas (NSCLCs) and define a distinct subpopulation of patients with lung cancer who are highly responsive to ALK kinase inhibitors, such as crizotinib. Because of this profound therapeutic implication, the latest National Comprehensive Cancer(More)
Variation in individual response to statin therapy has been widely studied for a potential genetic component. Multiple genes have been identified as potential modulators of statin response, but few study findings have replicated. To further examine these associations, 2735 individuals on statin therapy, half on atorvastatin and the other half divided among(More)
PURPOSE [(18)F]FLT (3'-Fluoro-3' deoxythymidine)-PET imaging was proposed as a tool for measuring in vivo tumor cell proliferation. The aim of this article was to validate the use of [(18)F]FLT-PET imaging for measuring xenograft proliferation and subsequent monitoring of targeted therapy. EXPERIMENTAL DESIGN In exponentially growing xenografts, factors(More)
Approximately 7% of non-small cell lung carcinomas (NSCLCs) harbor oncogenic fusions involving ALK, ROS1, and RET. Although tumors harboring ALK fusions are highly sensitive to crizotinib, emerging preclinical and clinical data demonstrate that patients with ROS1 or RET fusions may also benefit from inhibitors targeting these kinases. Using a(More)
Purpose: [F]FLT (30-Fluoro-30 deoxythymidine)–PET imaging was proposed as a tool for measuring in vivo tumor cell proliferation. The aim of this article was to validate the use of [F]FLT–PET imaging for measuring xenograft proliferation and subsequent monitoring of targeted therapy. Experimental Design: In exponentially growing xenografts, factors that(More)
Squalene synthase catalyzes the first committed step in cholesterol biosynthesis and thus is important as a potential target for therapeutic intervention. In order to determine the important functional domains of the protein, the amino and carboxyl terminal regions thought to be involved in membrane association of the enzyme were removed genetically. The 30(More)
To better understand the role of cholesteryl ester transfer protein (CETP) in cardiovascular disease, nine polymorphisms spanning the gene from the upstream promoter region to beyond the 3'UTR were genotyped in 2553 individuals from multiple ethnic groups and with different cardiovascular disease profiles. The frequency of four of these SNPs varied by(More)
The emerging application of pharmacogenomics in the clinical trial setting requires careful comparison with more traditional phenotyping methodologies, particularly in the drug metabolism area where phenotyping is used extensively. The research objectives of this study were 1) to assess the utility of cytochrome P450 2D6 (CYP2D6) genotyping as an(More)
The aim of this study was to determine the distribution of known oncogenic driver mutations in female never-smoker Asian patients with lung adenocarcinoma. We analyzed 214 mutations across 26 lung cancer-associated genes and three fusion genes using the MassARRAY LungCarta Panel and the ALK, ROS1, and RET fusion assays in 198 consecutively resected lung(More)
