Metabolomic profiles delineate potential role for sarcosine in prostate cancer progression.

Nature 457(7231) , 910-4, (2009)

Multiple, complex molecular events characterize cancer development and progression. Deciphering the molecular networks that distinguish organ-confined disease from metastatic disease may lead to the identification of critical biomarkers for cancer invasion an...

Relationship between glycopeptide production and resistance in the actinomycete Nonomuraea sp. ATCC 39727.

Antimicrob. Agents Chemother. 58(9) , 5191-201, (2014)

Glycopeptides and β-lactams inhibit bacterial peptidoglycan synthesis in Gram-positive bacteria; resistance to these antibiotics is studied intensively in enterococci and staphylococci because of their relevance to infectious disease. Much less is known about...

Bond dissociation of the dipeptide dialanine and its derivative alanine anhydride induced by low energy electrons.

J. Chem. Phys. 134(5) , 054305, (2011)

Dissociative electron attachment to dialanine and alanine anhydride has been studied in the gas phase utilizing a double focusing two sector field mass spectrometer. We show that low-energy electrons (i.e., electrons with kinetic energies from near zero up to...

Experimental strategies for functional annotation and metabolism discovery: targeted screening of solute binding proteins and unbiased panning of metabolomes.

Biochemistry 54(3) , 909-31, (2015)

The rate at which genome sequencing data is accruing demands enhanced methods for functional annotation and metabolism discovery. Solute binding proteins (SBPs) facilitate the transport of the first reactant in a metabolic pathway, thereby constraining the re...

Infrared spectroscopy of the alanine dipeptide analog in liquid water with DFT-MD. Direct evidence for P(II)/beta conformations.

Phys. Chem. Chem. Phys. 12 , 10198-10209, (2010)

Following our previous work [J. Phys. Chem. B. Lett., 2009, 113, 10059], DFT-based molecular dynamics (DFTMD) simulations of 2-Ala peptide (i.e. Ac-Ala-NHMe dialanine peptide analog with methyl group caps at the extremities) immersed in liquid water at room t...

Atomic multipoles: electrostatic potential fit, local reference axis systems, and conformational dependence.

J. Comput. Chem. 33(20) , 1673-88, (2012)

Currently, all standard force fields for biomolecular simulations use point charges to model intermolecular electrostatic interactions. This is a fast and simple approach but has deficiencies when the electrostatic potential (ESP) is compared to that from ab ...

Kinetic mechanism and inhibition of Mycobacterium tuberculosis D-alanine:D-alanine ligase by the antibiotic D-cycloserine.

FEBS J. 280(4) , 1150-66, (2013)

D-cycloserine (DCS) is an antibiotic that is currently used in second-line treatment of tuberculosis. DCS is a structural analogue of D-alanine, and targets two enzymes involved in the cytosolic stages of peptidoglycan synthesis: alanine racemase (Alr) and D-...

Selenium and selenomethionine levels in prostate cancer patients.

Cancer Detect. Prev. 28(1) , 8-16, (2004)

Selenium (Se) and selenomethionine (Se-Met) have been identified as potential chemopreventive agents of prostate cancer. Using an assay for the speciation (separation and identification) and quantification of selenoamino acids, Se-Met was profiled in serum an...

Urinary unconjugated 5 alpha-androstane-3 alpha, 17 beta-diol in patients with prostatic tumours.

Urol. Res. 10(2) , 81-4, (1982)

A sensitive and reliable radioimmunoassay (RIA) for urinary unconjugated 5 alpha-androstane-3 alpha, 17 beta-diol is described. The mean overall recovery of unconjugated 5 alpha-androstane-3 alpha, 17 beta-diol was found to be 57.4%. The sensitivity of the as...

Plasma carotenoids, retinol, and tocopherols and the risk of prostate cancer in the European Prospective Investigation into Cancer and Nutrition study.

Am. J. Clin. Nutr. 86(3) , 672-81, (2007)

Previous studies suggest that high plasma concentrations of carotenoids, retinol, or tocopherols may reduce the risk of prostate cancer.We aimed to examine the associations between plasma concentrations of 7 carotenoids, retinol, alpha-tocopherol, and gamma-t...
