Project description:Purpose: The purpose of this study are to identify the miRNA involved in regulating the production of metabolites in Chlorella sorokiniana and Chlorella zofingiensis under normal and stress-induced condition through RNA-sequencing technique. Methods: miRNA transcriptome profile from normal and stress sample of C. sorokiniana and C. zofingiensis were generated, in triplicate, using Illumina Miseq. The sequence reads that passed quality filters were analysed using CLC genomic workbench and OmiRas. Results: The known and predicted novel miRNAs were identified. Although most of the identified miRNAs were not functionally determined, this study suggests that they were species-specific, which may have roles in regulating genes during stress related condition.

Project description:Chlorella has been reported to have various physiological activities, including antiarteriosclerotic, cholesterol-lowering, anti-inflammatory, and immunoregulatory effects. However, there has been no report on the long-term effects of chlorella ingestion on immunity. In the present study, 4- to 10-week-old (young) and 4- to 50-week-old (old) female BALB/c mice were sensitized or not with ovalbumin (OVA), and given basic diet containing chlorella powder at 2% or basic diet alone. The effects of chlorella ingestion on immunity were investigated by measurement of splenic cytokines and immunoglobulin (Ig), analysis of T- and B-cells in the spleen and small intestine by flow cytometry, and analysis of the liver by DNA microarray. Results were compared between the young and old, OVA-sensitized and -nonsensitized, and chlorella and non-chlorella ingestion groups. Production of interferon-γ (IFN-γ) was maintained in the nonsensitized old groups, and ratios of T-helper type 1 (Th1) to T-helper type 2 (Th2) cells were similar in the young and old groups. In addition, overproduction of OVA-specific Igs due to OVA sensitization was strongly suppressed, and significant immunotolerance was exhibited irrespective of age. In addition, suppression of T-cell decreases in the spleen due to aging and suppression of changes in T- and B-cells due to OVA sensitization in the small intestinal lymph were demonstrated on flow cytometric analyses. On DNA microarray analysis, immune-related terms including IL11 and major histocompatibility complex (MHC) class 1 were detected, and expression of genes was shown, which were related to IL1-linked genes and complex involving macrophages from the pathways of cytokines and inflammatory response. In addition, suppressions of declined lipid metabolism and energy production were also suggested. Although how the ingredients in chlorella were involved in these changes is unclear, our findings suggest that prevention of decrease in acquired immunity by aging and induction of strong immunotolerance occurred following chlorella ingestion. The Young Control group and Old Control group were fed normal food, and the Old Chlorella intake group was fed food including 2.0% Chlorella powder. The total RNA was isolated from liver and samples was pooled for each group (n = 6 for each group). A table of normalized log2 ratios (where numerator is sample expression data, and denominator is all sample median data) is linked below as a supplementary file.

Project description:Green hydra (Hydra viridissima) harbors endosymbiotic Chlorella and have established a mutual relation. To identify the host hydra genes involved in the specific symbiotic relationship, transcriptomes of intact H. viridissima colonized with symbiotic Chlorella strain A99, aposymbiotic H.viridissima and H. viridissima artificially infected with other symbiotic Chlorella were compared by microarray analysis. The results indicated that genes involved in nutrition supply to Chlorella were upregulated in the symbiotic hydra. In addition, it was induced by supply of photosynthates from the symbiont to the host, suggesting cooperative metabolic interaction between the host and the symbiotic algae.

Project description:Chlorella has been used as a food supplement and has been reported to have health benefits. We used the forced swimming test to investigate the influence of Chlorella intake during muscle stress training in mice. Swimming time was about two-fold longer for the Chlorella intake mice than for the control mice. Microarray analysis revealed that the global expression profile of muscle from the Chlorella intake mice was similar to that for intact (nonswimming) mice rather than to that for control swimming mice. By contrast, oxidoreductase activity and the leukotriene synthesis pathway were repressed in Chlorella intake mice. According to measurement of the cytokine activities of primary cultures of spleen, Th1 cytokines, such as interferon-gM-cM-^CM-;and interleukin-2, and granulocyte colony-stimulating factors, such as MIP-1aM-cM-^CM-; GMCSF, and IP-10, were decreased in control swimming mice, but these cytokines were rescued in the Chlorella intake mice. We suggest that the immune response during muscle training can be repressed by intake of Chlorella. The intact (nonswimming) and control (swimming) groups were fed normal food, and the Chlorella intake (swimming) group was fed food including 0.5% Chlorella powder. After 14days, the total RNA was isolated from muscle and samples was pooled for each group (n = 10 for each group).

Project description:Diabetes and Arteriosclerosis progression are frequently observed in borderline Type 2 diabetes cases. Onset of complications (arteriosclerosis and renal damage) due to Type 2 diabetes is well documented; it is extremely important to prevent or delay their progression. Type 2 diabetes onset and progression has been controlled through dietary habits and exercise, although these remain insufficient. Chlorella ingestion improves blood glucose and cholesterol concentrations in mice and humans, although no reports have evaluated Chlorella effects in borderline diabetics. Therefore, we conducted a randomized, placebo-controlled trial for borderline diabetics using laboratory results and comprehensive gene analysis as outcomes. Chlorella ingestion suppressed resistin gene expression, suggesting that Chlorella may be useful for preventing diabetes onset and ameliorating arteriosclerosis. Subjects were randomly divided into two groups: Chlorella group (n = 28) ingesting Chlorella powder (8.0 g/day) and placebo group (n = 29) ingesting lactose formulation (8.0 g/day) for 12 weeks. Blood and urine were collected every 4 weeks for laboratory tests. Gene expression analysis used RNA extracted from peripheral blood samples before and after 12 weeks of Chlorella or lactose ingestion.
