Project description:Competition is a major determinant of plant community structure consisting of both species-specific and general interactions, either of which may influence competitive competency and plant abundance and size. In certain cases, competitive competency could arise from altered gene expression and plant function when an individual is confronted with new competitors. We explored competition at the molecular level by hybridizing transcripts from Centaurea maculosa (spotted knapweed), one of North America's most invasive exotic plant species, to an Arabidopsis microarray chip. Centaurea was grown in competition with Festuca idahoensis (Idaho fescue), a native grass species that generally has weak competitive effects against Centaurea; Gaillardia aristata (Indian blanketflower), a native herbaceous species that tends to be a much stronger competitor against Centaurea; or alone (control). The expression of some genes was found to be relatively uninfluenced by the type of plant neighbor, whereas other patterns of gene expression appeared to be more neighbor specific. To our knowledge, these results are the first to identify genes in an invasive plant that are induced or repressed by plant neighbors and provide a new avenue of insight into the molecular aspects of plant competitive ability. Keywords: treated vs.untreated First file, Chip 508 (9-9-05) is preliminary hyb data to see if this cross species hybridization is possible using the OAR27K chip Experiment 1 (chip 508): The Arabidopsis OAR27K gene chip was hybridized with labeled cDNA probes produced from samples of Centaurea RNA at the W.M. Keck Foundation Biotechnology Resource Laboratory, Yale University. The OAR27K gene chip consists of 70-mer oligos representing approximately 27,000 genes from Arabidopsis. Leaf and root samples were reverse-transcribed into cDNA and labeled with different fluorescent dyes (Cy3 and Cy5) using the Genisphere Array 900 kit (Cat No.W500180) (Genisphere, Hatfield PA). Labeled cDNAs were hybridized to the OAR27Kchip using the Advalytix ArrayBooster DNA Microarray Incubator (Advalytix, Boston MA). Approximately 10ug of each sample was used for hybridization.Experiment 2: Hybridization and labeling followed the procedure above, except the experimental control was Centaurea plants grown alone, and the test situations were Centaurea grown with Gaillardia or Festuca neighbors. In each experiment, RNA from Centaurea grown alone was used as the control (labeled with Cy3) and RNA from Centaurea grown with a neighbor was used as the test (labeled with Cy5). Two replicates were performed for each test situation.

Project description:Clinical studies have demonstrated that higher protein intake based on caloric restriction (CR) alleviates metabolic abnormalities. However, no study has examined the effects of plasma protein profiles on caloric restriction with protein supplementation (CRPS) in metabolic syndrome (MetS). Therefore, using a proteomic perspective, this pilot study investigated whether CRPS ameliorated metabolic abnormalities associated with MetS in middle-aged women. Methods: Plasma samples of middle-aged women with MetS in CR and CRPS groups for 12-week intervention were obtained and their protein profiles were analysed. Briefly, blood samples from qualified participants were drawn before and after the dietary treatment. Anthropometric, clinical, and biochemical variables were measured and correlated with plasma proteomics. Results: In results, we found that body mass index, total body fat, and fasting blood glucose decreased significantly after the interventions but were not different between the CR and CRPS groups. After liquid chromatography–tandem mass spectrometry analysis, the relative plasma levels of A2M, C4BPA, C1RL, C6, C8G, and PROS were significantly different between the CRPS and CR groups. These proteins are involved in inflammation, the immune system, and coagulation responses. Moreover, blood low-density lipoprotein cholesterol levels were significantly and positively correlated with C6 plasma levels in both groups. Conclusions: These findings suggest that CRPS improves inflammatory responses in middle-aged women with MetS. Specific plasma protein expression (i.e. A2M, C4BPA, C1RL, C6, C8G, and PROS) associated with the complement system was highly correlated with FBG, BLs, and body fat.

Project description:ObjectiveIncreased blood pressure (BP) is a major risk factor for cardiovascular disease (CVD) in adults. Regular consumption of nuts may improve some BP in adults whereas evidence in children is relatively lacking. This study aimed to determine the efficacy of nuts intake on BP in children.MethodsStratified cluster sampling was performed to include a total of 15,268 primary school children aged 6-12 years in urban and rural areas in Southwest China. The daily nuts intake dosage was collected by questionnaires, and generalized linear model (GLM) and logistic regression were used to analyze the relationship between nuts intake and BP.ResultsFor the total subjects, 11,130 (72.9%) participants consumed <35 g/day of nuts, 1,145 (7.5%) participants consumed 35 g/day ≤ nut <50 g/day of nuts, 2,053 (13.4%) participants consumed 50~100 g/day of nuts, and 940 (6.2%) participants consumed over 100 g/day of nut. For sex subgroup, 1,074 (13.53%) boys and 979 (13.35%) girls consumed 50~100 g/day of nuts. Compared with the 50~100 g/day of nuts intake group, systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were significantly different in <35 g/day, 35g/day ≤ nut <50 g/day, and >100 g/day nuts intake groups (all p < 0.001). The logistic regression showed that compared with the 50~100 g/day group, the other three groups are more likely associated with childhood hypertension (all p < 0.001). Therefore, a U-shaped relationship between nuts intake and BP level was identified.ConclusionsThe finding suggests that intake of 50~100 g/day nuts is the recommended dose of nuts intake to control childhood hypertension, as well as for cardioprotection purposes.

Project description:To explore the influence of choline intake and pregnancy status on gene expression, we employed whole genome microarray expression profiling to identify genes that were differentially expressed between two choline intake groups and between pregnant and non-pregnant women. Healthy third trimester (gestational week 26-29) pregnant women and non-pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6 pregnant and n=5 non-pregnant) or 930 (n=6 pregnant and n=5 non-pregnant) mg choline/d. Fasting peripheral blood leukocyte samples were collected at week 0 and week 12 to extract RNA and perform the arrays. Healthy third trimester (gestational week 26-29) pregnant women and non-pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6 pregnant and n=5 non-pregnant) or 930 (n=6 pregnant and n=5 non-pregnant) mg choline/d for 12 weeks. Fasting (10-h) peripheral blood leukocyte gene expression were measured at week 0 and week 12.

Project description:We aimed to investigate the effects of a wide range of daily physical activity (PA) levels on energy balance (EB), energy intake (EI), and appetite. Nine young men completed three different PA levels in a metabolic chamber in a random order: (1) no exercise (Low-PA); (2) 25 min walking seven times (Mid-PA); and (3) 25 min running seven times (High-PA) within a 24 h period. Interval exercise (25 min exercise and 35 min rest) was performed three times in the morning and four times in the afternoon. The exercise intensities were 21.6% and 53.7% V ˙ O₂ peak for the Mid-PA and High-PA days, respectively. Participants were served three standardized meals and a buffet for dinner. The 24 h EB was calculated as 24 h energy expenditure (EE) minus 24 h EI. The 24 h EEs for the Low-PA, Mid-PA, and High-PA days were 1907 ± 200, 2232 ± 240, and 3224 ± 426 kcal, respectively, with significant differences observed among the three conditions (p < 0.01 for Low-PA vs. Mid-PA, Low-PA vs. High-PA, and Mid-PA vs. High-PA, respectively). The 24 h EIs for the Low-PA, Mid-PA, and High-PA days were 3232 ± 528, 2991 ± 617, and 3337 ± 684 kcal, and were unaffected by PA levels (p = 0.115). The 24 h EBs were 1324 ± 441 kcal (Low-PA), 759 ± 543 kcal (Mid-PA), and 113 ± 430 kcal (High-PA), with significant differences observed between Low-PA vs. Mid-PA (p = 0.0496), Low-PA vs. High-PA (p ≤ 0.01), and Mid-PA vs. High-PA (p = 0.017) conditions. The EB in the Low-PA group was the highest of the three conditions. Appetite perception did not differ among the study days, however there was an interaction trend (p = 0.078, time × condition). Thus, significantly different daily PA did not affect 24 h EI, however markedly affected 24 h EB, implying that EB is not automatically matched during a single day.

Project description:The role of eosinophilic inflammation in chronic obstructive pulmonary disease (COPD) pathogenesis is unknown and is probably different than in asthma. The molecular processes underlying the differences between eosinophils from asthma and COPD have not been studied. The study group included 5 patients with asthma and 4 patients with COPD. The RNA-Seq data analysis identified 26 differentially expressed genes between COPD and asthma (according to adjusted p-value). In total, 6 genes were up-regulated (CCL3L1, CCL4L2, SERPINB2, PRSS21, GPR82) and 20 were down-regulated (e.g. JUN, IFITM3, DUSP1, GNG7, ZNF107, BCL6) in peripheral eosinophils of COPD patients compared to asthma. Biological processes associated with down-regulated genes were cell differentiation, positive regulation of RNA metabolic process. The genes associated with signaling of IL-4 and IL-13 pathway were down-regulated in COPD eosinophils compared to asthma. Peripheral eosinophils from COPD and asthma patients present different transcriptomic profiles suggesting their different function in pathobiology of both obstructive airway diseases.

Project description:Repetitive low-level blast exposure is one of the major occupational health concerns in the US mil-itary service members and law enforcement, and the underlying biological mechanisms remain controversial. Therefore, this study is to identify gene expression using RNA sequencing in the whole blood sample from experienced breachers and unexposed control. We performed experi-mental RNA sequencing using Illumina’s HiSeq 2500 Sequencing System in whole blood samples from 15 experienced breachers and 14 age, sex, race matched unexposed control. We identified 10 significantly dysregulated genes between experienced breacher and unexposed control with FDR corrected < 0.05. One upregulated gene included LINC00996 (long intergenic non-protein coding RNA 996) and 9 downregulated genes including IGLV3-16 (immunoglobulin lambda variable 3-16), CD200 (CD200 molecule), LILRB5 (leukocyte immunoglobulin like receptor B5), ZNF667-AS1 (ZNF667 antisense RNA 1), LMOD1 (leiomodin 1), CNTNAP2 (contactin associ-ated protein 2), EVPL (envoplakin), DPF3 (double PHD fingers 3), and IGHV4-34 (immunoglobu-lin heavy variable 4-34). Dysregulated of these genes’ expression are associated with nervous system development and organismal development. The dysregulated gene expression reported in our study is functionally associated with chronic inflammation and immune response in repeti-tive low-level blast exposure, which may have a negative influence on neurological health.

Project description:Innate and adaptive immunity plays important roles in the development and progression of cancer and it is becoming apparent that tumors can influence the induction of potentially protective responses in a number of ways. The prevalence of immunoregulatory T cell populations in the circulation and tumors of patients with cancer is increased and the presence of these cells appears to present a major barrier to the induction of tumor immunity. One aspect of tumor-mediated immunoregulation which has received comparatively little attention is that which is directed toward natural killer (NK) cells, although evidence that the phenotype and function of NK cell populations are modified in patients with cancer is accumulating. Although the precise mechanisms underlying these localized and systemic immunoregulatory effects remain unclear, tumor-derived factors appear, in part at least, to be involved. The effects could be manifested by an altered function and/or via an influence on the migratory properties of individual cell subsets. A better insight into endogenous immunoregulatory mechanisms and the capacity of tumors to modify the phenotype and function of innate and adaptive immune cells might assist the development of new immunotherapeutic approaches and improve the management of patients with cancer. This article reviews current knowledge relating to the influence of tumors on protective anti-tumor immunity and considers the potential influence that radiation-induced effects might have on the prevalence, phenotype, and function of innate and adaptive immune cells in patients with cancer.
