Association of the c.385C>A (p.Pro129Thr) polymorphism of the fatty acid amide hydrolase gene with anorexia nervosa in the Japanese population.

Hide Abstract
The functional c.385C>A single-nucleotide polymorphism (SNP) in the fatty acid amide hydrolase (FAAH) gene, one of the major degrading enzymes of endocannabinoids, is reportedly associated with anorexia nervosa (AN). We genotyped the c.385C>A SNP (rs324420) in 762 lifetime AN and 605 control participants in Japan. There were significant differences in the genotype and allele frequencies of c.385C>A between the AN and control groups. The minor 385A allele was less frequent in the AN participants than in the controls (allele-wise, odds ratio = 0.799, 95% confidence interval [CI] 0.653-0.976, P = 0.028). When the cases were subdivided into lifetime restricting subtype AN and AN with a history of binge eating or purging, only the restricting AN group exhibited a significant association (allele-wise, odds ratio = 0.717, 95% CI 0.557-0.922, P = 0.0094). Our results suggest that having the minor 385A allele of the FAAH gene may be protective against AN, especially restricting AN. This finding supports the possible role of the endocannabinoid system in susceptibility to AN.

Induction of AhR-mediated gene transcription by coffee.
PLoS ONE

Show Abstract
Hide Abstract
Aryl hydrocarbon receptor (AhR) is classically known to be activated by xenobiotics such as dioxins and polycyclic aromatic hydrocarbons (PAHs). Although it has been reported that PAHs are contained in roasted coffee beans, in general coffee beverages are not considered to be AhR activators. We tested whether exposure to coffee would activate AhR in cultured cells.

Dipeptidyl-peptidase 4 inhibitors have become one of the most popular antidiabetic drugs. However, what kind of combinations with other drugs were advantageous was not known. Here, we tried to elucidate it in a real-life clinical setting.

No association of brain-derived neurotrophic factor Val66Met polymorphism with anorexia nervosa in Japanese.

Show Abstract
Hide Abstract
The Met66 allele of the Val66Met polymorphism in the brain-derived neurotrophic factor (BDNF) gene has been reported to be associated with anorexia nervosa (AN), and also lower minimum body mass index (BMI) and higher harm avoidance in AN. We genotyped the Val66Met polymorphism (rs6265) in 689 AN cases and 573 control subjects. There were no significant differences in the genotype or allele frequencies of the Val66Met between AN and control subjects (allele wise, odds ratio?=?0.920, 95% CI 0.785-1.079, P?=?0.305). No difference was found in minimum BMIs related to Val66Met in AN (one-way ANOVA, P?>?0.05). Harm avoidance scores on the Temperament and Character Inventory were lower in the Met66 allele carriers (P?=?0.0074) contrary to the previous report. Thus we were unable to replicate the previous findings that the Met66 allele of the BDNF is associated with AN and that the minimum BMI is lower or the harm avoidance score is higher in AN patients with the Met66 allele.

A ghrelin gene variant may predict crossover rate from restricting-type anorexia nervosa to other phenotypes of eating disorders: a retrospective survival analysis.
Psychiatr. Genet.

Show Abstract
Hide Abstract
Patients with anorexia nervosa restricting type (AN-R) often develop bulimic symptoms and crossover to AN-binge eating/purging type (AN-BP), or to bulimia nervosa (BN). We have reported earlier that genetic variants of an orexigenic peptide ghrelin are associated with BN. Here, the relationship between a ghrelin gene variant and the rate of change from AN-R to other phenotypes of eating disorders (EDs) was investigated.

A SNP of NPC1L1 affects cholesterol absorption in Japanese.

Show Abstract
Hide Abstract
Ezetimibe is known to target Niemann-Pick Type C1 Like1 (NPC1L1), a key protein in intestinal cholesterol absorption, and thus to decrease serum LDL-cholesterol (LDL-C) levels. The response of serum LDL-C levels to ezetimibe was reported to differe among NPC1L1 haplotypes.We analyzed NPC1L1 genotypes in Japanese and investigated differences in markers of cholesterol synthesis/absorption among the genotypes.

Critical promoter region for statin-induced human endothelial nitric oxide synthase (eNOS) transcription in EA.hy926 cells.
J. Atheroscler. Thromb.
Show Abstract
Hide Abstract
Statins have many anti-atherogenic effects apart from reducing the serum level of low density lipoprotein cholesterol (LDL-C). For instance, statins can enhance the expression of endothelial nitric oxide synthase (eNOS), at least partly by upregulating its transcription. Although it has been reported that -786 T/C polymorphism of the promoter region has an important influence on statininduced transcription of the human eNOS gene, much remains unclear about statin-induced eNOS transcription. We tried to identify other statin-responsive promoter regions.

Serum from methimazole-treated patients induces activation of aryl hydrocarbon receptor, a transcription factor that binds to dioxin-response elements.
Thyroid
Show Abstract
Hide Abstract
The aryl hydrocarbon receptor (AhR) is a transcription factor that is activated by xenobiotic substances such as dioxin. After activation, it binds to dioxin response elements of DNA, thereby inducing transcription of a variety of xenobiotic metabolizing enzymes. To investigate whether AhR-activating substances accumulate in patients with endocrine disorders, we tested serum samples for AhR-stimulating activity.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
