Abstract

To explore the effect of alpha1,2-fucosyltransferase (alpha1,2-FT) gene on the biological behavior of ovarian carcinoma cells, the expression vector pcDNA3.1 -HFUT-H which containing human alpha1,2-FT gene coding region was constructed and transfected into ovarian carcinoma cell line RMG-I. alpha1,2-FT gene expression, Lewis y antigen expression, alpha1,2-FT activity, rates of cell growth and tumorogenesis in nude mice were compared before and after RMG-I being transfected. The transfection of alpha1,2-FT gene significantly increased the expression of alpha1,2-FT gene and Lewis y antigen in RMG-I cells. After the transfection, RMG-I cells showed remarkable improvement of alpha1,2-FT activity, cell proliferation, the ability of colony formation in soft agar and tumorogenesis in nude mice. The growth rates of alpha1,2-FT gene transfected RMG-I cells were obviously increased, presenting that the proportion of the cells in G2-M and S phases was obviously increased from 2.05% to 7.32% and from 23.95% to 33.27% respectively, and that of the cells in G1 phase was obviously decreased from 74.14% to 59.46%, as compared with the control group. These findings indicate that alpha1,2-FT and Lewis y antigen have the ability to enhance the pr...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.
