Project description:Affymetrix expression analysis was used to check transcipt expression in As (V) stress. The RNA from root of six rice genotypes (BRG-12, BRG-15, BRG-20, CN1646-5, NAYANMONI and CN1646-2) was isolated after 24 hrtreatment of As (V) 0M-BM-5m and 50M-BM-5m .The rice gene chip was used for expression analysis.

Project description:We utilized high-throughput sequencing and subsequent signaling pathway analyses to find all the 2 fold change expression of transcripts in comparison of brain microvascular endothelial cells derived from six Sprague Dawley rats without or with irradiation at the dose of 5 Gy or 20 Gy and then cultured for 12 h or 24 h
Project description:Aim: To find the genes that related with the drug's(7-P) function. Design: 36 Rats were randomly divided into three group:control group(12), model group(12) and drug group(12). At last, randomly choosing 3 Rat from each group to do genechip analysis. In model group, the Porcine serum was given intraperitoneally (i.p.) to rats in a volume of 1.5 mL/kg every 3 days for a total of 20 treatments. Effect on model animals was confirmed by liver histology and biochemical assays . In drug group, 7-P was dissolved in balanced saline solution for administration subcutaneously at dosages of 174 μg/kg in a volume of 1 mL/kg. The doses were given 15 times, one day interval. In control group, the animals were not treated with porcine serum. but given an equal volume of vehicle alone. During 7-P and vehicle administration, porcine serum was given intraperitoneally (i.p.) to rats in a volume of 1.5 mL/ kg once weekly. All animals were fasted for 24 h before porcine serum treatment. Background: During investigation of hypervariable region 1 (HVR1) of hepatitis C virus (HCV), a seven amino acids mimic peptide named 7-P was identified within the N-terminal of HVR1 that could induce IFN-γ and IL-10 expression while decreasing the expression of TNF-α in vivo and in vitro. Further studies revealed that 7-P could not only decrease the serum levels of aminotransferases (ALT, AST), alkaline phosphatase (AKP), and billirubin, but were also effective in reversing histopathological evidence of inflammation-mediated hepatic injury in 3 rat models. The protective mechanism and gene expression profiles were investigated in detail in a rat chronic liver injury model using Affymetrix microarrays . Conclusion: We found that IL-1β, tumor necrosis factor receptor superfamily 14 (TNFRSF14), intercellular adhesion molecule 2 (ICAM2), sterol regulatory element-binding protein 1 (SREBP 1), Prohibitin (PHB), and inhibitor of DNA binding 2 (Id2) were the target genes that related with 7-P Keywords: comparative genomic hybridization
Project description:How do the transcript levels of leaf-expressed genes change in a normal day-night cycle? The interest is in genes that are regulated by the circadian clock and the diurnal component (i.e. light, metabolite changes). Plants were grown on soil in a 12/12 h light/dark rythm at 20°C day and night. 5 weeks after germination the rosettes of the non-flowering plants were harvested, 15 plants per sample. Plants were harvested at 6 timepoints every 4 hours beginning with the end of the night (still in darkness). Keywords: repeat
Project description:Bud endodormancy induction response of two genotypes (‘Seyval’ a hybrid white wine grape and V. riparia, PI588259 a native north american species) was compared under long (15h) and short (13h) photoperiod. Three separate replicates (5 plants/replicate) were treated to generate paradormant (LD) and same aged endodormancy-induced (SD) buds for transcriptomic, proteomic and metabolomic analysis. Potted, spur-pruned two to six-year-old vines were removed from cold storage (Seyval 3-19-07; V. riparia 3/26/07) and grown under a LD (15 h) at 25/20 + 3C day/night temperatures (D/N). When vines reached 12-15 nodes (3-25-07) they were randomized into LD or SD treatments with 25/20 + 3C D/N in climate controlled greenhouses with automated photoperiod system (VRE Greenhouse Systems). Three replications (5 vines/replication) were harvested between 5/07-6/07 and then again in 5/08-6/08 for a total of six replications. All treatments are repeated at the same time every year and harvested at the same time of day each year to minimize biological noise. At 1, 3, 7, 14, 21, 28 and 42 days of LD and SD treatment, buds were harvested from nodes 3 to 12 of each separate replicate, immediately frozen in liquid nitrogen, and placed at -80C for future RNA, protein and metabolite extraction. These time points encompass early reversible phases as well as key time points during transition to irreversible endodormancy development. After photoperiod treatments and bud harvests, all pruned vines were returned to LD and monitored for bud endodormancy. The endodormant vines were identified after 28 days and moved to cold storage. The nondormant vines were allowed to grow again and induced into dormancy at a later date.
