Project description:Our previous studies have linked Trans-fat and monosodium glutamate (MSG) to the development of Nonalcoholic Fatty Liver Disease (NAFLD). We have also shown that MSG can interact with another commonly consumed food additive, aspartame, to impair glucose homeostasis, which is also disrupted in NAFLD. This most recent nutrigenomic study shows how aspartame, MSG and Trans-fat can unfavorably alter hepatic and adipose tissue gene expression. We used microarray analysis to examine changes in adipose gene transcription in response to TFA MSG and/or ASP feeding in male C57Bl/6J mice.

Project description:The major surface glycoprotein (Msg) is the most abundant surface protein of Pneumocystis species. Given that Msg is present on both the cyst and trophic form of Pneumocystis, and dendritic cells play a critical role in initiating host immune responses, we undertook studies to examine activation of bone marrow-derived myeloid dendritic cells by Msg purified from P. murina. Incubation of dendritic cells with Msg did not lead to increased expression of CD40, CD80, CD86, or MHCII, or increased secretion of any of 10 cytokines. Microarray analysis identified very few differentially expressed genes. In contrast, LPS activated dendritic cells by all of these assays. However, Msg did bind to mouse mannose macrophage receptor and human DC-SIGN, two C-type lectins expressed by dendritic cells that are important in recognition of pathogen-associated high mannose glycoproteins. Deglycosylation of Msg demonstrated that this binding was dependent on glycosylation. These studies suggest that Pneumocystis has developed a mechanism to avoid activation of dendritic cells, potentially by the previously identified loss of genes that are responsible for the high level of protein mannosylation found in other fungi.

Project description:The middle silk gland (MSG) is an important silkworm sub-organ for synthesis and secretion of sericin proteins. To investigate the proteome differences among the anterior, middle, and posterior regions of silkworm MSG at the third day of the fifth instar, the extracted tissue proteins were digested in gel with trypsin followed by shotgun LC-MS/MS analysis with a LTQ-Orbitrap mass spectrometer.

Project description:To identify functions that distinguish the posterior and median cells producing fibroin and sericin in the silk gland of Bombyx mori, serial analysis of gene expression (SAGE) profiles from both silk gland regions were analyzed and compared. The construction of a B. mori reference tag collection extracted from a set of 38000 Bombyx EST sequenced from the 3’ side, helped annotating the SAGE libraries. Most of the tags appeared at similar relative concentration in the two libraries except for those corresponding to silk proteins that were found region-specific and highly abundant. Strikingly, besides tags from silk protein mRNAs, 19 tags were found in the class of high abundance in the median cell library, which were absent in the posterior cell tag collection. Except tags from SP1 mRNA, no PSG specific tags were found in the same class of abundance. The analysis of MSG-specific different transcripts led to suggest that middle silk gland cell realizes more diversified functions as those already known, of synthesis and secretion of the silk sericins. EST libraries from 11 silkworm tissues were 3’-sequenced to ensure the identification of the most terminal tag. 37,920 sequences were analyzed on ABI 3700 or 3730XL sequencers. Electrophoregrams were processed with KB Basecaller (3730XL traces) or with PHRED (3700 traces) to obtain the .phd files from which were extracted text sequences and their corresponding quality files in Fasta format (Phd2Fasta, Green and Ewing, 1995; 2002). Vector sequences and bad quality regions were removed with an home made software after identification by Lucy (Chou and Holmes, 2001). Chimera were removed by an home made software and retrotransposon sequences were masked by RepeatMasker (http://repeatmasker.org). The cleaned sequences were clusterized with TGICL package (TIGR) and assembled into contigs with CAP3 (Huang and Madan, 1999). Contigs were identified with Blastn and Blastx on GenBank and SwissProt/TREMBL, respectively. Some clusters, splitted by CAP3 procedure, have been regrouped on the basis of Blastx identity. Identitag (Keime et al., 2004) was used to extract all possible tags (forward and reverse) to create a reference database. Moreover, a quality index is attached to each tag depending to the presense of poly-A, polyadenylation signal and its proximity to 3-prime extremity in the original mRNA sequence. This database was supplemented with the tags extracted from public B. mori sequences (GenBank, Silkbase) with the same software. Tags were extracted from MSG and PSG libraries (from 2304 and 3072 sequenced inserts respectively) with the Sagenhaft software (Beissbarth et al., 2004) then identified and compared with Identitag. The assessment of significant differences among the two libraries was performed by using the Z-test used for comparison of SAGE libraries of different size (Kal et al., 1999). For graphic purpose and to avoid division by zero we used a tag value of 1 for tags that were not detected in MSG or PSG libraries. Since the two SAGE libraries showed up different TAG number, we used the Z-test for comparing the two mRNA populations.

Project description:Gender dimorphism exists in the physiological response to diet and other environmental factors. Trans-hydrogenated fatty acid (TFA) intake is associated with an increase in coronary heart disease (CHD), and gender differences in the incidence of CHD are well documented. Neonatal administration of Monosodium Glutamate (MSG) causes stunted heart growth and hypoplasticity; and gender dimorphism at the growth hormone axis has been demonstrated in MSG-treated rodents. The identification of gender dimorphism in cardiac nutrigenomics may provide the basis for gender-specific medicine in the future. We used microarray analysis to examine changes in cardiac gene transcription in response to TFA and/or MSG feeding in male and female C57Bl/6J mice.

We used microarray analysis to examine changes in cardiac gene transcription in response to TFA and/or MSG feeding in male and female C57Bl/6J mice. Our study animals were bred from female C57Bl/6J mice fed a standard chow diet until 6 weeks of age whereupon they were placed on one of 4 different dietary regimens for a period of 3 weeks prior to mating. The four dietary regimens used in this study were: [1] Standard Chow (Control diet) with ad lib drinking water. [2] Standard Chow, with ad lib drinking water containing 0.64 g/L Monosodium Glutamate (MSG diet). [3] Trans fat diet of 20% (w/w) Partially Hydrogenated Vegetable Shortening containing 8.68% w/w Trans fatty acids(TFA diet). [4] Trans fat Diet #5C4M together with ad lib drinking water containing 0.64 g/L Monosodium Glutamate (TFA+MSG diet). Following mating, the 4 groups of dams were maintained on their respective diets throughout the gestation and nursing period. Male and female offspring used in the following experiments were weighed, weaned onto the same diets and maintained on their respective dietary regimens until they reached 32 weeks of age.Cardiac tissues (8 per diet group) were used at 32 weeks for RNA extraction and hybridization on Affymetrix microarrays.
