Glucocorticoids are associated with lipid metabolism and their abnormal expression has an important function in the development of metabolic syndrome. The 11β‑hydroxysteroid dehydrogenase type 1 (11β‑HSD1) is a metabolic enzyme of glucocorticoids and may be a potential drug target for the treatment of metabolic syndrome. However, the association between the systemic expression of 11β‑HSD1 and metabolic syndrome remains to be elucidated. The present study used a cytomegalovirus promoter to obtain mice that systemically overexpressed the 11β‑HSD1 gene...

Both fasting and treatment with a high-fat diet (HFD) can dramatically change fat metabolism in the liver and, thus, are commonly used methods to investigate hepatic fat metabolism and related diseases. Here, the gene expression profiles of pig liver under both conditions were investigated and changes in hepatic triacylglycerol (TG) levels under different diet conditions were determined. In this study, both fasting and HFD conditions significantly increased hepatic TG levels and serum levels of cholesterol, TG, high-density lipoprotein, low-density lipoprotein, and apolipoprotein B...

The tea green leafhopper, Empoasca vitis Göthe, is one of the most serious pests in tea growing areas. This study investigated the roles played by olfaction and vision in host orientation behavior. The compound eye of E. vitis was found to be a photopic eye; few olfactory sensilla were found on the antennae, while abundant gustatory sensilla were recorded on the mouthparts. Three opsin genes (EV_LWop, EV_UVop, EV_Bop) were isolated and found to be mainly expressed in the compound eye compared with other parts of the body...

Neural tube defects (NTDs) occur secondary to failed closure of the neural tube between the third and fourth weeks of gestation. The worldwide incidence ranges from 0.3 to 200 per 10,000 births with the United States of American NTD incidence at around 3-6.3 per 10,000 dependent on race and socioeconomic background. Human NTD incidence has fallen by 35-50% in North America due to mandatory folic acid fortification of enriched cereal grain products since 1998. The US Food and Drug Administration has approved the folic acid fortification of corn masa flour with the goal to further reduce the incidence of NTDs, especially among individuals who are Hispanic...

Female under-nutrition during early pregnancy may affect the physiological pattern of the transcriptomic profile in the endometrium. We aimed to determine if restricted diet applied to females during peri-conceptional period, that is, from the onset of the oestrus until day nine of pregnancy, alters transcriptomic profile in the endometrium during the peri-implantation period. The restricted diet gilts were fed forage, in which the dose of proteins and energy had been reduced by 30% compared to normal diet...

Carotenoids have important roles in bird behavior, including pigmentation for sexual signaling and improving color vision via retinal oil droplets. Yellow carotenoids are diet-derived, but red carotenoids (ketocarotenoids) are typically synthesized from yellow precursors via a carotenoid ketolase. Recent research on passerines has provided evidence that a cytochrome p450 enzyme, CYP2J19, is responsible for this reaction, though it is unclear if this function is phylogenetically restricted. Here I provide evidence that CYP2J19 is the carotenoid ketolase common to Aves using the genomes of 65 birds and the retinal transcriptomes of 15 avian taxa...

Trichoplusia ni insect larvae infected with vectors derived from the Autographa californica multiple nucleopolyhedrovirus (AcMNPV), are an excellent alternative to insect cells cultured in conventional bioreactors to produce recombinant proteins because productivity and cost-efficiency reasons. However, there is still a lot of work to do to reduce the manual procedures commonly required in this production platform that limit its scalability. To increase the scalability of this platform technology, a current bottleneck to be circumvented in the future is the need of injection for the inoculation of larvae with polyhedrin negative baculovirus vectors (Polh-) because of the lack of oral infectivity of these viruses, which are commonly used for production in insect cell cultures...

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder that is closely associated with insulin resistance and type 2 diabetes. Previous studies have suggested that hepatocyte nuclear factor 1b (HNF1b) ameliorates insulin resistance. However, the role of HNF1b in the regulation of lipid metabolism and hepatic steatosis remains poorly understood. We found that HNF1b expression was decreased in steatotic livers. We injected mice with lentivirus (LV) expressing HNF1b shRNA to generate mice with hepatic knockdown of HNF1b...

BACKGROUND: The oriental fruit fly, Bactrocera dorsalis (Hendel), is a notorious world pest infesting fruit and vegetable, which has evolved high level of resistance to many commonly used insecticides. In this study, we investigated whether tyrosine hydroxylase (TH) that is required for cuticle tanning (sclerotization and pigmentation) in many insects, could be a potential target in controlling B. dorsalis. RESULTS: We cloned TH cDNA (BdTH) of B. dorsalis, and the complete open reading frame of BdTH (KY911196) was 1737 bp in length, encoding a protein of 578 amino acids...

OBJECTIVE: Epididymal adipose tissue (EAT), a visceral fat depot, is more closely associated with metabolic dysfunction than inguinal adipose tissue (IAT), a subcutaneous depot. This study evaluated whether the nuclear receptor RORα, which controls inflammatory processes, could be implicated. METHODS: EAT and IAT were compared in a RORα loss-of-function mouse (sg/sg) and in wild-type (WT) littermates, fed a standard diet (SD) or a Western diet (WD), to evaluate the impact of RORα expression on inflammatory status and on insulin sensitivity (IS) of each fat depot according to the diet...

BACKGROUND: Rare sugars including D-allulose, D-tagatose, and D-sorbose are present in limited quantities in nature; some of these rare sugars are now commercially produced using microbial enzymes. Apart from the anti-obesity and anti-hyperglycemic activities of D-allulose, effects of these sugars on lipid metabolism have not been investigated. Therefore, we aimed to determine if and how D-tagatose and D-sorbose modulate lipid metabolism in rats. After feeding these rare sugars to rats, parameters on lipid metabolism were determined...

Communities of symbiotic microorganisms that colonize the gastrointestinal tract play an important role in food digestion and protection against opportunistic microbes. Diet diversity increases the number of symbionts in the intestines, a benefit that is considered to impose no cost for the host organism. However, less is known about the possible immunological investments that hosts have to make in order to control the infections caused by symbiont populations that increase due to diet diversity. By using taxonomical composition analysis of the 16S rRNA V3 region, we show that Enterococci are the dominating group of bacteria in the midgut of the larvae of the greater wax moth (Galleria mellonella)...

Context: Hypertension in young women is uncommon compared to young men and older women. Estrogen appears to protect most women against hypertension with incidence increasing after menopause. Since some premenopausal women develop hypertension, estrogen may play a different role in these women. Genetic variations in the estrogen receptor (ER) are associated with cardiovascular disease. ER-β, encoded by ESR2, is the ER predominantly expressed in vascular smooth muscle. Objective: To determine an association of single nucleotide polymorphisms (SNPs) in ESR2 with salt-sensitivity of blood pressure (SSBP) and estrogen status in women...

Allometric growth of ducts in the mammary glands (MG) is widely-held to be estrogen (E)-dependent. We previously discovered that the dietary fatty acid trans-10, cis-12 conjugated linoleic acid (CLA) stimulates E-independent allometric growth and TEB formation in ovariectomized mice. Given the similar phenotype induced by E and CLA, we investigated the shared and/or divergent mechanisms underlying these changes. We confirmed MG growth induced by CLA is temporally distinct from that elicited by E, then used RNA-Sequencing to compare the transcriptome of the MG during similar proliferative and morphological states...

Atherosclerosis, a serious threat to human cardiovascular health, involves inflammation throughout its various stages of development. MicroRNAs play an important regulatory role in macrophages that respond to inflammation, but the underlying mechanisms are largely unknown. In this work, we study the impact of miR-19a in macrophage-derived foam cell formation during atherogenesis. A microarray-based analysis of serums from patients with coronary heart disease in comparison with healthy controls reveals a significant enrichment of miR-19a in the serums of atherosclerosis patients...

The innate inflammatory response contributes to secondary injury in brain trauma and other disorders. Metabolic factors such as caloric restriction, ketogenic diet, and hyperglycemia influence the inflammatory response, but how this occurs is unclear. Here, we show that glucose metabolism regulates pro-inflammatory NF-κB transcriptional activity through effects on the cytosolic NADH:NAD(+) ratio and the NAD(H) sensitive transcriptional co-repressor CtBP. Reduced glucose availability reduces the NADH:NAD(+) ratio, NF-κB transcriptional activity, and pro-inflammatory gene expression in macrophages and microglia...
