Session 4: Application of Molecular Biology inIn Vitro Toxicology

Toxicology in Vitro : an International Journal Published in Association with BIBRA
L Wärngård

Abstract

The implementation of molecular biology in vitro toxicology has been a challenge over the last years. The present session had the special task of discussing how this new technique could be integrated and used by toxicologists. The session consisted of five different lectures. The first lecture was an overview concerning the role of cytokines in toxicology. This lecture was followed by a discussion on the topic of how effects of xenobiotics on target cells reflect the toxicity in vivo. In the third lecture the use of gene expression pattern as molecular endpoint for mechanistic toxicity was discussed, and it was suggested that array of systems would be a valuable tool in the near future. This lecture was followed by two mechanistically related lectures dealing with lead-induced alteration of gene expression in the retina, followed by a discussion concerning mechanisms of signal transduction mediated by the dioxin receptor. These lectures demonstrated that there is a need to understand the complexity before we simplify a biological process. In summary, the session discussed future possibilities for studying toxic responses in a more mechanistically direct way and how pattern recognition of altered gene expression could be an impo...Continue Reading

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.
