Mutagens from the cooking of food. I. Improved extraction and characterization of mutagenic fractions from cooked ground beef

Mutation Research

Abstract

Ground beef was fried at 200 degrees C (392 degrees F) to a well-done, non-charred state, and the extracted organic base fraction was found to be highly mutagenic in Salmonella strain TA1538 (6300 revertants/100 g equivalent, gE, fresh weight). The neutral and acidic extracts showed no mutagenic activity in any of the 5 standard strains of Salmonella. A new procedure based upon extraction and protein precipitation with acetone is described, which is simpler and more efficient than previously described methods. The organic base fraction was mutagenic only in Salmonella strains TA1537, TA1538, and TA98, all sensitive to frameshift mutations. Strains sensitive to base-substitution mutations showed no activity. Metabolic activation was an absolute requirement for mutagenesis; however cell toxicity was decreased by the presence of S9 activation mixture. After normal cooking, more than 20 times as much mutagenic material remained in the meat as was recovered in the pan grease and vapors. The results confirm that mutagens are formed under conventional frying conditions, and show that mutagen can be isolated by an improved extraction method.

COVID-19

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

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.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
