Project description:Atractylodes macrocephala is a traditional Chinese medicine in China. It is widely used in clinic and the market demand is great. The quality difference between A. chinensis(Bunge) Koidz and A. japonica Koidz.ex Kitam is great, which seriously affects its clinical curative effect. Determination of Atractylosin by High-performance liquid chromatography. Transcriptomics coupled with Metabonomics for elucidating differences between the components in A. chinensis(Bunge) Koidz and A. japonica Koidz.ex Kitam. It was found that ACS, ACC, PAL and NOS were the key genes and metabolites related to the synthesis of atractylodes macrocephala. The decrease of salicylic acid content in A. chinensis(Bunge) Koidz may lead to the decrease of its ability to mediate the elicitor of endophytic fungi, resulting in the down-regulation of the expression of TGAL4 transcription factor and the up-regulation of DOGL3 transcription factor in A. chinensis(Bunge) Koidz cells, which may affect the accumulation of Atractylosin. The study above provides a theoretical basis for elucidating the biosynthesis pathway of atractylosin in A. chinensis(Bunge) Koidz.
Project description:Autologous fat grafting (AFG), although an appealing approach to repair soft tissue defects, has various complications. Excessive inflammation at the transplant site is one of the main reasons for the poor effect of fat transplantation and occurrence of complications. Our previous study proved that Salvia miltiorrhiza can enhance fat graft survival. Salvianolic acid B (Sal-B) is the most abundant and bioactive water-soluble compound in Salvia miltiorrhiza and has anti-inflammatory effects on other diseases. Therefore, we hypothesized that salvianolic acid B could improve the effect of fat grafts by inhibiting inflammation.
Project description:To further investigate the potential molecular basis of the therapeutic effects of the mixture of salvianolic acids from Salvia miltiorrhiza and total flavonoids from Anemarrhena asphodeloides (MSTF) on sulfur mustard (SM) damage, gene expression analysis was conducted on rats liver tissues using microarrays.

Project description:Endophytic fungus influences hairy root of Salvia miltiorrhiza
Project description:Salvia is an important genus from the Lamiaceae with approximately 1000 species distributed globally. Several Salvia species are commercially important because of their medicinal and culinary properties. We report the construction of the first fingerprinting array for Salvia species enriched with polymorphic and divergent DNA sequences and demonstrate the potential of this array for fingerprinting several economically important members of this genus. In order to generate the Salvia Subtracted Diversity Array (SDA), a Suppression Subtractive Hybridization (SSH) was performed between a pool of ten Salvia species and a pool of non-angiosperm and angiosperms (excluding the Lamiaceae) to selectively isolate Salvia-specific sequences. A total of 285 subtracted genomic DNA (gDNA) fragments were amplified and arrayed. DNA fingerprints were obtained for fifteen Salvia genotypes including three that were not part of the original subtraction pool. Hierarchical cluster analysis indicated that the Salvia-specific SDA was capable of differentiating closely related species of S. officinalis and S. miltiorrhiza and was also able to reveal genetic relationships consistent with geographical origins. Species-specific features were also found for S. elegans, S. officinalis, S. sclarea, S. przewalskii and S. runcinata.
Project description:Salvia miltiorrhiza is one of the most popular traditional medicinal herbs in Asian nations. Its dried root contains a number of tanshinones, protocatechuic aldehyde, salvianolic acid B and rosmarinic, and is used for the treatment of various diseases. To make clear the molecular mechanism of tanshinones biosynthesis in S. miltiorrhiza, the tissue-specific miRNAs and their target genes were identified by high-throughput sequencing and degradome analysis. A total of 452 known miRNAs corresponding to 589 pre-miRNAs, and 40 novel miRNAs corresponding to 24 pre-miRNAs were identified in different tissues of S. miltiorrhiza, respectively. Among them, 62 miRNAs express only in root, 95 miRNAs express only in stem, 19 miRNAs express only in leaf, and 71 miRNAs express only in flower, respectively. By the degradome analysis, 69 targets potentially cleaved by 25 miRNAs were identified. Among them, Acetyl-CoA C-acetyltransferase was identified in S. miltiorrhiza, which was cleaved by miR5072 and involved in the biosynthesis of tanshinones. This study provided valuable information for understanding the tissues expression patterns of miRNAs, and offered a foundation for future studies of the miRNA-mediated tanshinones biosynthesis in S. miltiorrhiza.
