Project description:Radix bupleuri is a traditional Chinese crude drug and it is still widely used in contemporary medicine. Bupleurum chinense DC. and B. scorzonerifolium Willd. are officially recorded as the source species of Radix bupleuri in Pharmacopoeia of the PeopleM-bM-^@M-^Ys Republic of China. The obvious difference in chemical active components and pharmacological action of Radix bupleuri derived from the two species has caused attention. But to date, no definite criterions and regulates are issued based on plant species sources to direct the standard uses of Radix bupleuri for their extracts and traditional decoction pieces in medical market. Using 454-FLX pyrosequencing with one half-plate run for each cDNA library, a total of 419,576 and 416,112 reads, among those 313,483 and 342,263 high quality ESTs were obtained for B. chinense and B. scorzonerifolium, respectively. The average read length was 279 bp and 310 bp, respectively. The assembled 28,897 and 30,912 unigenes for B. chinense and B. scorzonerifolium were successively annotated based on sequence similarity by major public nucleotide/protein databases, Nt, Nr, SwissProt, KEGG, COG, Interpro and GO. Based on the alignments, 71.9% (20,787) and 75.8% (23,426) of the total unigenes for B. chinense and B. scorzonerifolium could be matched to nucleotides from NCBI Nt database. Certain percent from 27.1% (7,820) to 70.8% (20,461) of the total unigenes for B. chinense, and from 26.4% (8,145) to 72.1% (22,289) of the total unigenes for B. scorzonerifolium, could be matched to proteins from different databases. For the same database, similar percent of the total unigenes for B. chinense and B. scorzonerifolium were annotated. A total of 17,117 (59.2%) and 19,416 (62.8%) unigenes for B. chinense and B. scorzonerifolium could be found homologous genes in opposite dataset. According to KEGG annotation, 3,637 and 3,821 unigenes were assigned relating to metabolism in datasets of B. chinense and B. scorzonerifolium, respectively. Carbohydrate metabolism, energy metabolism and amino acid metabolism were the highest three groups in metabolism category and followed by lipid metabolism group for B. chinense. In comparison, lipid metabolism group had most unigenes for B. scorzonerifolium and it had much more unigenes than the same group for B. chinense (827 to 562). A total of 70 and 52 unigenes were related to metabolism of terpenoids and polyketides in two separate datasets, which seems agree with the situation of higher content of terpenoid saikosaponins in B. chinense than B. scorzonerifolium in some extent. To compare the biosynthesis of main bioactive components in roots of B. chinense and B. scorzonerifolium, putative genes which may participate in the biosynthesis of terpenoid, triterpenoid, sterol, ligan and flavonoid were searched according to unigenes annotation. Most lignan and flavonoid biosynthesis related genes were found in both datasets of B. chinense and B. scorzonerifolium, while some terpenoid or triterpenoid related genes were dominantly found in the dataset of B. chinense. This reflected in some extent that these genes expressed in low levels and relative metabolites were biosynthesized in lower quantities in roots of B. chinense than those of B. scorzonerifolium. Besides abovementioned comparison on two transcriptome, the expression of some genes involved in biosyntheses of main medicinal secondary metabolites were analyzed by qRT-PCR in roots of the two species. These molecular biological data will make a useful clue and arouse more studies on the reasonable application of the two Bupleurum species. The fine roots of two-year old plants of B. chinense and B. scorzonerifolium planted in the same place at the same time were collected at the usual harvest time of medicinal materials of Bupleurum. Those roots from the two species plants were used for 454 sequencing.

Project description:Purpose: We aimed to provide a basis for the adaptive mechanism and a rich resource for the discovery and identification of novel genes involved in the cold and heat stress response in Solenopsis invicta. retinal transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis Methods: Solenopsis invicta was reared at lab condition, and incubated at 4 different temperature for 24h (10, 20, 30 and 40℃). RNA was extracted using Trizol reagent and Illumina sequencing was performed at Macrogen. Illumina short reads were quality-filtered and Illumina-based de novo transcriptome assembly was performed. Differential Gene Expression Analysis was studied for different tempearture conditions. Results: Totally 99,085 unigenes was obtained which at least 19,154 were annotated with gene descriptions, gene ontology terms, and metabolic pathways. 86 GO functional sub-groups and 23 EggNOG terms resulted. DEGs with log2FC≥10 were screened and were compared at different temperatures. We found 203, 48 and 66 specific DEGs co-regulated at 10, 20 and 40℃, respectively compare with 30℃. Comparing transcriptome profiles for differential gene expression resulted various DE proteins and genes, including cytochrome P450, NADH dehydrogenase subunit 1, cuticle protein and HSP which have previously been reported to be involved in cold and high temperature resistance. GO analysis revealed that antioxidant activity up-regulated under high temperature stress. Conclusions: we compared the transcriptomes of S. invicta under high- and low-temperature stresses using RNA-Seq technology based on the high-throughput sequencing. Comparative transcriptome analysis identified many genes and a large number of changes were discovered in metabolic pathway through the GO and KEGG enrichment analysis. Our data will facilitate further molecular investigations and genomic research. Many high- and low-temperature significantly up-regulated genes were first identified in this study. These newly found genes may be important and necessary to RIFA overwintering and its behavior for adaptation in new environment as well as quarantine area.

Project description:Typical rodent toxicology experiments are performed at human thermoneutral temperatures (thermostandard; TS = 20 – 24° C). Reports have indicated that investigation of metabolic endpoints at mouse thermoneutral temperatures (TNM = 28 – 30° C) improves translation to humans when they are not chronically cold-stressed. 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) has been shown to dose-dependently induce metabolic disease in mice at including liver steatosis, steatohepatitis, and periportal fibrosis. To test whether dose-dependent hepatotoxicity caused by TCDD is altered by housing temperature we gavaged male C57BL/6 mice every 4 days for 28 days with TCDD (0.03 – 30 µg/kg) or sesame oil vehicle at TS and TNM. Mice held at TNM exhibited less marked relative liver weight gain and histopathology with milder steatosis, immune cell infiltration, hepatocellular hypertrophy, and an absence of biliary hyperplasia compared to mice held at Ts. Mice housed in both temperature conditions had a similar dose-dependent decrease in total cholesterol, but mice at TS had more elevated serum ALT and decreased glucose and triglycerides at 30 µg/kg TCDD. Mice at TNM had fewer differentially expressed genes (DEGs) than TS, although most of the DEGs at TNM were shared with the DEGs at TS. Benchmark Dose (BMD) analysis performed on the DEGs revealed largely similar trends, however, the most induced DEGs, which constituted some of the AhR-battery genes (e.g. Cyp1a1), exhibited lower BMDs at TNM. Moreover, at 30 µg/kg TCDD both sets of mice had increased pro-inflammatory cytokines. The only cytokine which was clearly different between the two sets of mice irrespective of dose was VEGF-A. Overall, mice held at TNM showed reduced severity at equivalent doses to mice held at TS.

Project description:Projected elevation of seawater temperatures poses a threat to the reproductive success of Caribbean reef-building corals that have planktonic development during the warmest months of the year. This study examined the transcriptomic changes that occurred during embryonic and larval development of the elkhorn coral, Acropora palmata, at a non-stressful temperature (28°C) and further assessed the effects of two elevated temperatures (30°C and 31.5°C) on these expression patterns. Using cDNA microarrays, we compared expression levels of 2,051 genes from early embryos and larvae at multiple developmental stages (including pre-blastula, blastula, gastrula, and planula stages) at each of the three temperatures. At 12 hours post-fertilization in 28°C treatments, genes involved in cell replication/cell division and transcription were up-regulated in A. palmata embryos, followed by a reduction in expression of these genes during later growth stages. From 24.5 to 131 hours post-fertilization at 28°C, A. palmata altered its transcriptome by up-regulating genes involved in protein synthesis and metabolism. Temperatures of 30°C and 31.5°C caused major changes to the A. palmata embryonic transcriptomes, particularly in the samples from 24.5 hpf post-fertilization, characterized by down-regulation of numerous genes involved in cell replication/cell division, metabolism, cytoskeleton, and transcription, while heat shock genes were up-regulated compared to 28°C treatments. These results suggest that increased temperature may cause a breakdown in proper gene expression during development in A. palmata by down-regulation of genes involved in essential cellular processes, which may lead to the abnormal development and reduced survivorship documented in other studies.

Project description:Transcriptome changes were investigated for Euphorbia esula (leafy spurge) seeds with a focus on the effect of constant and diurnal fluctuating temperature on dormancy and germination. Leafy spurge seeds do not germinate when incubated for 21 days at 20°C constant temperatures, but nearly 30% germinate after 21 days under fluctuating temperatures 20:30°C (16:8 h). Incubation at 20°C for 21 followed by 20:30°C resulted in approximately 63% germination in about 10 days. A cDNA microarray representing approximately 22,000 unique sequences was used to profile transcriptome changes.

Project description:Purpose: We aimed to use RNA-Seq and de novo transcriptome assembly to produce transcriptomes and analyze the changes in transcription regulation associated with cold and heat treatment in Spodoptera frugiperda. A detailed differential expression analysis revealed a number of candidate genes that may be associated with FAW cold and heat tolerance. To validate the RNA-seq results, we used qRT-PCR. We hoped to provide a foundation for the adaptive mechanism as well as a rich resource for the discovery and detection of novel genes involved in cold and heat stress responses of Spodoptera frugiperda. Methods: Spodoptera frugiperda was reared at lab condition, and incubated at 2 different temperature( 4 and 40°C) for 16 hours as temperature treatment groups. RNA was extracted using Trizol reagent and Illumina sequencing was performed at Macrogen. Illumina short reads were quality-filtered and Illumina-based de novo transcriptome assembly was performed. Differential Gene Expression Analysis was studied for different tempearture conditions. Results: A total of 211,967 unigenes were collected, at least 14,338 of which were annotated with gene descriptions, gene ontology terms, and metabolic pathways. There were 50 GO functional sub-groups and 21 EggNOG words as a result. DEGs with log2FC≥2 were identified and compared at various temperatures. In comparison to the 25°C treated group, we discovered 199 and 1248 individual DEGs co-regulated at 4 and 40°C, respectively. Comparing transcriptome profiles for differential gene expression revealed a number of DE genes, including cytochrome P450, odorant binding proteins (OBP), and immune system genes previously implicated in cold and high temperature resistance. The enrichment pathways were identified using KEGG analysis, and heatmaps of similar unigenes from both treatment groups (T4 and T40) were plotted. We used qPCR to confirm the RNA-seq data on 10 up- and down-regulated DEGs. Conclusions: In conclusion, we used RNA-Seq technology focused on high-throughput sequencing to compare the transcriptomes of Spodoptera frugiperda under high- and low-temperature stresses. This research was the first to identify a large number of genes that were significantly up-regulated at high and low temperatures. Many genes were discovered through comparative transcriptome analysis, and a significant number of improvements in metabolic pathways were discovered through GO and KEGG enrichment analysis. Our findings will help future molecular research and genomic studies. These newly found genes may be important and necessary to FAW harsh environment tolerance and its behavior for adaptation in new environment as well as quarantine area.

Project description:Visceral white adipose tissue is closed correlated with obesity and metabolic dysfunction. Epididymal adipose tissue (eWAT) is considered as typical visceral white adipose tissue. Induction of browning of white adipose tissue improves metabolic dysfunction such as insulin resistance. In contrast to mice subcutaneous adipose tissue, visceral fat do not show significant browning under 4°C. However,under physiologically tolerable low temperature visceral adipose tissue can turn brown. We used microarrays to detail the global programme of gene expression in C57Bl/6 mice epididymal adipose tissue exposed to thermoneutral 30°C, 4°C and temperatures lower than 4°C.
