Invited review article featured on cover of Chemical
Research in Toxicology (July 1998)
The May 1998, Volume 11, Number 5, issue
of Chemical Research in Toxicology featured a graphic entitled
"Arylamine-DNA Adducts" taken from an article co-authored by ORNL
staff member, Brian E. Hingerty. The article is "Nuclear Magnetic
Resonance Solution Structures of Covalent Aromatic Amine-DNA Adducts and
Their Mutagenic Relevance," by Dinshaw J. Patel, Bing Mao, Zhengtian
Gu, Brian E. Hingerty, Andry Gorin, Ashis K. Basu, and Suse Broyde. This
invited review article featured a comprehensive review of all high
resolution nuclear magnetic resonance solution structures of DNAs damaged
by carcinogenic polycyclic aromatic amines, substances which are widespread
in the environmental in tobacco smoke, automobile exhaust, and broiled
foods. Much of the featured work represented seminal studies carried out
in a collaboration involving the high resolution NMR laboratory of Dinshaw
Patel at Memorial Sloan Kettering Cancer Center with Suse Broyde at New
York University and Brian Hingerty at ORNL. The NERSC computer center at
Lawrence Berkeley National Laboratory was the primary site for the
computations in this extensive collaboratory. The studies have revealed
the structural themes that these mutagenic substances adopt when attached
to DNA, providing for the first time the molecular views which reveal the
initiation event of carcinogenesis by these environmental
chemicalstheir attack on DNA which can lead to a mutation that may
eventually produce tumors.
