The cis-(5R,6S)-thymine glycol lesion occupies the wobble position when mismatched with deoxyguanosine in DNA.

18 Oct 2009 Oxidative damage to 5-methylcytosine in DNA, followed by deamination, yields thymine glycol (Tg), 5,6-dihydroxy-5,6-dihydrothymine, mispaired with deoxyguanosine. The structure of the 5R Tg.G mismatch pair has been refined using a combination of ... Read more...

A lectin HPLC method to enrich selectively-glycosylated peptides from complex biological samples.

29 Sep 2009 Glycans are an important class of post-translational modifications. Typically found on secreted and extracellular molecules, glycan structures signal the internal status of the cell. Glycans on tumor cells tend to have abundant sialic acid and ... Read more...

High-throughput ultra-high-performance liquid chromatography/tandem mass spectrometry quantitation of insulin-like growth factor-I and leucine-rich alpha-2-glycoprotein in serum as biomarkers of recombinant human growth hormone administration.

29 Sep 2009 Insulin-like growth factor-I (IGF-I) is a known biomarker of recombinant human growth hormone (rhGH) abuse, and is also used clinically to confirm acromegaly. The protein leucine-rich alpha-2-glycoprotein (LRG) was recently identified as a putative ... Read more...
