Height is a complex genetic trait that involves multiple genetic loci. Recently, 44 loci associated with height were identified in Caucasian individuals by large-scale genome-wide association (GWA) studies. To identify genetic variants influencing height in the Korean population, we analyzed GWA data from 8842 Korean individuals and identified 15 genomic(More)
The Bradyrhizobium japonicum NtrBC two-component system is a critical regulator of cellular nitrogen metabolism, including the acquisition and catabolism of nitrogenous compounds. To better define the roles of this system, genome-wide transcriptional profiling was performed to identify the NtrC regulon during the response to nitrogen limitation. Upon cells(More)
Single nucleotide polymorphisms (SNPs) appeal to the forensic DNA community because of their abundance in the human genome, low mutation rate, small amplicon size, and feasibility of high-throughput genotyping technologies. In an initial screening, we identified six SNP markers of sex determination by resequencing the amelogenin genes and the zinc finger(More)
Flavonoids, secondary plant metabolites which mainly have a polyphenolic structure, play an important role in plant-microbe communications for nitrogen-fixing symbiosis. Among 10 polyphenolic compounds isolated from soybean roots in our previous study, coumestrol showed the highest antioxidant activity. In this study, its effect on the soybean nodulation(More)
Lipopolysaccharides (LPSs) are major components of the outer membrane of Gram-negative bacteria and are essential for their growth and survival. They act as a structural barrier and play an important role in the interaction with eukaryotic hosts. Here we demonstrate that a photosynthetic Bradyrhizobium strain, symbiont of Aeschynomene legumes, synthesizes a(More)
In this study, we attempted to purify and characterize glutaminase (EC. 3.5.1.2) from Lactobacillus reuteri KCTC3594. The glutaminase was purified approximately 21-fold from the cell-free extract of L. reuteri KCTC3594 by protamine sulfate treatment and chromatography methods including anion exchange and gel filtration. The sizes of two major bands of the(More)
This study investigated the effects of umbelliferone (UF) on alcoholic fatty liver and its underlying mechanism. Rats were fed a Lieber-DeCarli liquid diet with 36% of calories as alcohol with or without UF (0.05 g/L) for 8 weeks. Pair-fed rats received an isocaloric carbohydrate liquid diet. UF significantly reduced the severity of alcohol-induced body(More)
There is increasing evidence that alcohol-induced white adipose tissue (WAT) dysfunction contributes to disturbance of hepatic lipid metabolism. This study investigated the effects of scopoletin on lipid homeostasis and inflammation at the WAT and liver in chronic alcohol-fed rats. Rats were fed a liquid diet containing 5% alcohol with or without two doses(More)
A genome-wide transcriptional profile of Bradyrhizobium japonicum, the nitrogen-fixing endosymbiont of the soybean plant, revealed differential expression of approximately 15% of the genome after a 1 mM treatment with the phytohormone indole-3-acetic acid (IAA). A total of 1,323 genes were differentially expressed (619 up-regulated and 704 down-regulated)(More)
Propionibacterium acnes has been known to be involved in the pathology of acne. However, the definite mechanism in the development of acne and the inflammation are unknown. For P. acnes, a transformation method has not been established, although it is believed to be a basic tool for gene manipulation. This study attempted to develop a P. acnes(More)
