Abstract

To analyze the genotypes of glucose-6-phosphate dehydrogenase (G6PD) gene mutations, and investigate the incidence of G6PD deficiency and gene frequency in She Nationality (SN) in Fujian province. G6PD deficiency was screened by NBT method, G6PD mutations identified by amplification refractory mutation system (ARMS), mismatch-PCR with a restriction endonuclease, PCR-SSCP and DNA sequencing. Among 1820 Qingshui SN and 764 Muyun SN, 101 and 104 samples were found to be abnormal, and the G6PD gene frequency accounted for 0.0607 and 0.1706 respectively. Among 54 pure ethnic descent SN samples in Muyun SN, 38 were identified as 1376G-->T, 10 as 1388G --> A and 6 as 95A-->G. The frequencies were 70.3%, 18.5% and 11.1% respectively. One case with both 1388G-->A and 95A-->G and another case with both 1376G-->T and 1388G-->A. Six 1024C-->T and one 392G -->T in Qingshui SN were identified. (1)G6PD nt1376G-->T and G6PD nt1388G-->A are two main variants in Muyun SN. Chinese ethnic groups share the similar G6PD gene variants, suggesting originated from the same ancestor. (2) 5 variants are found in SN: G6PD nt1376G-->T, nt1388G-->A, nt95A-->G, nt1024C-->T and nt392G-->T. (3) One with both nt1376G-->T and nt95A-->G mutations, another with bo...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.
