Project description:VAAM stands for an amino acid mixture simulating the composition of Vespa, a hornet larval saliva. We conducted a comparative study on metabolism-regulatory roles of VAAM, casein-simulating amino acid mixture (CAAM), and pure water on murine hepatic and adipose tissue transcriptomes. Mice were orally fed VAAM solution ( 0.675 g/ kg BW = 2% of food-derived amino acids = 0.38% of total food energy/ day), CAAM solution ( 0.675 g / kg BW/ day) or water under ad libitum for five days. Hepatic transcriptome comparison of VAAM, CAAM and water-treated groups revealed a VAAM-specific regulation of the metabolic pathway, i.e., the down-regulation of glycolysis and fatty acid oxidation, and up-regulation of poly unsaturated fatty acid synthesis and glycogenic amino acids utilization in TCA cycle. Similar transcriptomic analysis of white and brown adipose tissues (WAT and BAT) suggested the up-regulation of phospholipid synthesis in WAT and the negative regulation of cellular processes in BAT. Because these coordinated regulations of tissue transcriptomes implicated the presence of upstream signaling common to these tissues, we conducted Ingenuity Pathways Analysis of these transcriptomes with the results that estrogenic and glucagon signals seemed to be activated in liver and WAT as well as beta-adrenergic signaling did in the three tissues by administration of VAAM. Our data provide a clue to understanding the role of VAAM in metabolic regulation of multiple tissues.

Our data provide a clue to understanding the role of VAAM in metabolic regulation of multiple tissues. Mice were divided randomly into three groups, VAAM, CAAM or water administered group. VAAM, CAAM or water was orally administrated five times once a day using feeding tube. The dosage of 1.8%VAAM, 1.8%CAAM or water was 37.5 microliter per gram of body weight. On day of last administration, food was removed and mice were moved to clean cages at 8:00. The last administrations started at 10:00. At 4 hours later after last administration, mice were sacrificed by cervical dislocation to collect blood, liver, white adipose tissue (WAT) and brown adipose tissue (BAT). Small hepatic pieces were immersed into RNAlater. WAT and BAT were frozen immediately after extraction using liquid nitrogen. All samples were extracted total RNA and hybridized on Affymetrix microarrays.

Project description:The composition of the salivary microbiota has been reported to differentiate between patients with periodontitis, dental caries and orally healthy individuals. Thus, the purpose of the present investigation was to compare metaproteomic profiles of saliva in oral health and disease. Stimulated saliva samples were collected from 10 patients with periodontitis, 10 patients with dental caries and 10 orally healthy individuals. Samples were analyzed by means of shotgun proteomics. 4161 different proteins were recorded out of which 1946 and 2090 were of bacterial and human origin respectively. The human proteomic profile displayed significant overexpression of the complement system and inflammatory mediators in periodontitis and dental caries. Bacterial proteomic profiles and functional annotation were very similar in health and disease. Data revealed multiple potential salivary proteomic biomarkers of oral disease. In addition, comparable bacterial functional profiles were observed in periodontitis, dental caries and oral health, which suggest that the salivary microbiota predominantly thrives in a planktonic state expressing no characteristic disease-associated metabolic activity. Future large-scale longitudinal studies are warranted to reveal the full potential of proteomic analysis of saliva as a biomarker of oral health and disease.

Project description:This study elucidated the role of DHA-modulated genes in the development and growth of bluefin tuna (Thunnus thynnus) larvae ingesting increasing levels of DHA in their rotifer prey. The effect of feeding low, medium, and high rotifer (Brachionus rotundiformis) DHA levels (2.0, 3.6 and 10.9 mg DHA g-1 DW, respectively) was tested on 2-15 days post hatching (dph) bluefin tuna larvae. Larval DHA content markedly (P < 0.05) increased in a DHA dose-dependent manner (1.5, 3.9, 6.1 mg DHA g-1 DW larva, respectively), that was positively correlated with larval prey consumption, and growth (P < 0.05). Gene ontology enrichment analyses of DEGs demonstrated dietary DHA significantly (P < 0.05) affected different genes and biological processes at different developmental ages. The number of DHA up-regulated DEGs was highest in 10 dph larvae (408), compared to 5 (11) and 15 dph fish (34), and were mainly involved in neural and synaptic development in the brain and spinal cord. In contrast, DHA in older 15 dph larvae elicited fewer DEGs but played critical roles over a wider range of developing organs. The emerging picture underscores the importance of DHA-modulated gene expression as a driving force in bluefin tuna larval development and growth.
