The three mammalian transforming growth factor beta (TGF-beta) isoforms are each secreted in a latent complex in which TGF-beta homodimers are non-covalently associated with homodimers of their respective pro-peptide called the latency-associated peptide (LAP). Release of TGF-beta from its LAP, called activation, is required for binding of TGF-beta to(More)
The chromatographic quantitation of 8-oxoguanine adducts in DNA is widespread in the literature, although results obtained by HPLC of 8-oxodeoxyguanosine do not always agree with levels determined by GC-MS. To help explain this discrepancy, here we describe a novel procedure for the analysis of 8-oxoguanine adducts in DNA. Although it proved difficult to(More)
The oxidative base lesion 8-oxo-deoxyguanosine (8-oxo-dG) has been identified in DNA isolated from normal tissue and may occur at elevated levels during disease. However, the use of phenol during DNA extraction may artificially elevate the detected levels of this lesion. Herein, we have performed a comparative methodological study using both pronase E and(More)
Oxidative damage is thought to play a role in the aetiology of aging and a number of diseases including cancer, chronic inflammation, ischemia, degenerative arterial and autoimmune diseases [I]. 8-oxodeoxyguanosine (8-oxodG), an oxidative DNA adduct. has gained much popularity as a biomarker of damage to DNA. HPLC combined with electrochemical detection(More)
