ABSTRACT: Microarray analysis of the therapeutic effects of the mixture of salvianolic acids from Salvia miltiorrhiza and total flavonoids from Anemarrhena asphodeloides on sulfur mustard-induced damages
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: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. Rats were randomly assigned to one of the three following treatment groups (10 rats per group): normal control, SM and SM + MSTF. SM was dissolved in propylene glycol. The SM was applied with subcutaneous injection as a single dose of 3.5 mg/kg body weight equivalent to 0.7 LD50. The equivalent volume of solvent was given to control rats. MSTF (120 mg/kg body weight/day) dissolved in double distilled water were administered intragastrically to the rats 1 h after SM treatment. Twenty-four hours following SM treatment, the rats were subjected to anesthesia and then sacrificed by cervical dislocation. Liver was dissected out from each animal. 3-4 of these liver tissues were processed for the microarray experiment.

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:Salvianolic acid B (Sal-B) is the most abundant and bioactive water-soluble compound in Salvia miltiorrhiza. Studies have shown that salvianolic acid B increases the mRNA expression of adipogenic transcription factors, including PPARγ, C/EBPα and PPARα, in 3T3-L1 preadipocytes to increase glucose uptake and mitochondrial respiration, reduce glycerol release and promote adipocyte differentiation. However, the effect of Sal-B on graft fat survival and its specific mechanism have not been investigated. So we dicided using h-ADSCs to see its transcriptomes changing after Sal-B addition.
Project description:Skin aging is a complex biological process that is influenced by multiple factors, including environmental and genetic factors. Ultraviolet (UV) irradiation can cause short-term sun damage, such as erythema and edema, as well as chronic damage, which accelerates skin aging and produces skin wrinkles and skin laxity. Salvianolic acid B (Sal-B) is the most abundant and bioactive water-soluble extractant from the well-known herbal medicine--Salvia Miltiorrhiza in Chinese traditional medicine. Many studies have found that Sal-B exerts powerful antioxidant and anti-inflammatory effects. Therefore, we speculate that salvianolic acid B may have potential therapeutic value in the aspect of anti-photoaging.
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. The tissue-specific miRNAs and their target genes were identified by high-throughput sequencing and degradome analysis.

Project description:Salvianolic acid is the secondary metabolic products of Salvia miltiorrhiza, and its biosynthesis is induced and regulated by all kinds of abiotic factors. Our results showed that content of salvianolic acid including caftaric acid, salvianolic acid B, roamarinic acid, and salvianolic acid H was increased more than 50 times by UV-B radiation in leaves of Salvia miltiorrhiza. Further proteomic analysis identified 436 significantly proteins which are contributed to salvianolic acid accumulation under UV-B radiation. Among of them, photosynthesis related proteins were decreased, protein processing and phenolic acids synthesis related confirmed and potential key enzymes including cinnamoyl-CoA reductase, rosmarinic acid synthase, phenylalanine ammonia-lyase, were increased in UV-B treated danshen
