Abstract

The vitamin K epoxide reductase complex subunit 1 (VKORC1) gene is expressed in many tissue types, and encodes the VKORC1 protein, which is a key enzyme in the vitamin K cycle. Although researchers have focused on the effects of vitamin K on glucose metabolism, and on its role in the development of type 2 diabetes (T2DM), no consensus has yet been reached. Therefore, here we aimed to investigate the association between VKORC1 variants and the risk of T2DM. The 3673G / A (rs9923231) and 9041G / A (rs7294) VKORC1 variants were investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 100 control individuals and 100 patients with T2DM. The genomic regions were amplified by PCR; amplicons were digested using the AciI and NciI enzymes and visualized by agarose gel electrophoresis. The genotype frequencies of the 3673G / A variants were GG (22%), GA (56%), and AA (22%) in the control group and GG (19%), GA (52%), and AA (29%) in patients with T2DM (p > 0.05). The genotype frequencies of the 9041G / A variants were GG (37%), GA (53%), and AA (10%) in the control group and GG (46%), GA (45%), and AA (9%) in patients with T2DM (p > 0.05). In conclusion, we found no significant correlation between t...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.
