32P-postlabelling analysis of DNA adducts in white blood cells of humans exposed to residential wood combustion particulate matter

Environmental and Molecular Mutagenesis
G A HeussenG M Alink


Residential wood combustion (RWC) in open fireplaces poses a possible health risk because of the emission into the indoor air of mutagenic and carcinogenic compounds. In the present report it was investigated whether this emission leads to enhanced levels of DNA adducts in white blood cells (WBC) of exposed subjects. Under conditions that most likely reflect the Dutch pattern of use of open fireplaces, RWC increased both indoor air mutagenicity and levels of benzo(a)pyrene (B(a)P) and pyrene. The indirect mutagenicity showed a stronger increase than the direct mutagenicity. The increase in indirect mutagenicity was not directly correlated with the increase in the levels of B(a)P and pyrene. 32P-postlabelling analysis of DNA adducts following nuclease P1 enrichment or butanol extraction revealed low adduct levels. No combustion-related increase in the amount of adducts was observed. Possible explanations for the lack of correlation between air monitoring data and WBC DNA adduct levels are discussed.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
