Role of lipid peroxidation in the toxicity of T-2 toxin

Recent reports suggest that lipid peroxidation may be involved in the toxicity of T-2 toxin. In the present study the influence of T-2 toxin on two parameters of lipid peroxidation was examined: the formation of thiobarbituric acid reactive material in isolated hepatocytes and liver homogenates from rats and ethane exhalation in vivo. In isolated hepatocytes there was no significant increase in thiobarbituric acid reactive material, neither after addition of T-2 toxin in vitro nor when the toxin had been applied to the rats 15 hr before preparation of hepatocytes. In liver homogenates the amount of thiobarbituric acid reactive material was increased up to 50% over the controls, depending on the dose of T-2 toxin. The increased values are difficult to interpret, because the extent of the increase depends on the method used for determination of thiobarbituric acid reactive material. Measuring another parameter of lipid peroxidation, i.e. ethane exhalation, there was no difference between the T-2 toxin treated rats and the controls whereas carbon tetrachloride treated rats exhaled high amounts of ethane. These results suggest that lipid peroxidation does not play a major role in T-2 toxin toxicity.

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.

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.
