Project description:we used high-throughput Illumina Genome Analyzer IIx (GAIIx) technology to sequence the small RNA transcriptomes of the mangrove species, Avicennia marina. Based on sequence similarity or the secondary structure of precursors, we have identified 193 conserved miRNAs and 26 novel miRNAs in the small RNA transcriptome of Avicennia marina.

Project description:<p>Gut microbiota modulation by a probiotic is a novel therapy for hypercholesterolemia mitigation. This study initially investigated the potential hypocholesterolemic effect of Bacillus sp. DU-106 in hypercholesterolemic rats and explored its potential relation with gut microbiota. Sprague-Dawley rats received a high-fat diet, or a high-fat diet supplemented with 7.5 × 10<sup>9</sup> and 1.5 × 10<sup>10</sup> CFU/kg bw/day Bacillus sp. DU-106 (low-dose and high-dose groups). At the end of 9 weeks, Bacillus sp. DU-106 treatment significantly decreased the body weight, liver index, and total cholesterol. 16S rRNA sequencing showed that Bacillus sp. DU-106 intervention significantly increased bacterial richness and particularly increased the genus abundance of Turicibacter, Acinetobacter, Brevundimonas, and Bacillus and significantly decreased the abundance of Ralstonia. Metabolomic data further indicated that the supplementation of Bacillus sp. DU-106 remarkably changed the gut metabolic profiles of hypercholesterolemic rats and, in particular, elevated the metabolites of indole-3-acetate, methylsuccinic acid, creatine, glutamic acid, threonine, lysine, ascorbic acid, and pyridoxamine. Spearman's correlation analysis showed the close relation between the different genera and metabolites. In conclusion, Bacillus sp. DU-106 supplement ameliorated high-fat diet-induced hypercholesterolemia and showed potential probiotic benefits for the intestine.</p><p><strong>KEY POINTS:</strong> • A novel potential probiotic Bacillus sp. DU-106 ameliorated hypercholesterolemia in rats. • Bacillus sp. DU-106 supplement regulated gut microbiome structure and richness. • Bacillus sp. DU-106 supplement changed metabolic profiles in high-fat diet rats. • Significant correlations were observed between differential genera and metabolites.</p>
