Abstract

Cytochrome P-450 CYP2C9 enzyme is involved in the metabolism of xenobiotics and carcinogens. Variant alleles CYP2C9*2 and CYP2C9*3 encode enzymes with altered properties, and CYP2C9*2 has been related to lung cancer risk. The frequency of CYP2C9 variant alleles was analyzed in genomic DNA from 104 patients with lung cancer and in 197 healthy controls. No statistically significant differences in CYP2C9 genotypes, allele frequencies or predicted phenotypes were observed between overall patients and controls. Unconditional logistic regression for the interaction smoking/genotype indicate P values of 0.66 and 0.62 for carriers of CYP2C9*2 and CYP2C9*3, respectively, versus individuals without these mutations. The P values for the same interaction in carriers of one and two mutated genes were 0.56 and 0.67, respectively, versus individuals homozygous for non-mutated genes. Independent analyses of histological types of lung cancer also indicated the absence of statistically significant differences as compared to healthy subjects. Association between CYP2C9 polymorphism and lung cancer risk was not identified in this study.

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.
