Abstract

We report a study of polymorphism for seven short tandem repeat (STR) loci in Japanese and Chinese populations. Among 104 to 134 individuals in the both population samples, eight alleles were revealed for locus PLA2, thirteen for D3S1359, eleven for FGA, eight for D8S315 (kw38), ten for D8S1132, five for CYP19, and seven for D3S2459. They correspondingly constituted 10 to 39 genotypes therein. For most of the STRs, there was only a single allele active as the most frequent one among the others, except locus D3S1359 in Chinese samples (two alleles, 206 bp and 210 bp, frequency = 0.273 each). Also, the population genotype configurations were locus specific, varying in the patterns of commonest genotypes on each locus, e.g., one pattern for loci CYP19, D3S1359, and D8S315, one and two for loci PLA2 and D3S2459, two for locus D8S1132, and one and four for locus FGA. The distributions of observed genotypes were in Hardy-Weinberg Equilibrium. Furthermore, the seven STRs were exhibited highly polymorphic and informative for the both populations, and the alleles could be easily separated in electrophoresis and correctly interpreted with side-to-side allelic ladders. Together, the results suggest that the tri- and tetra-meric STRs are u...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.
