Over-expression of bHLH122 in Arabidopsis

ABSTRACT: bHLH122 could be induced by salt, osmotic and drought stress except ABA, the transgentic Arabidopsis were more tolerant to abiotic stresses, such as drought and salt. What's more, in the overexpression plants, the endogenesis ABA contents were higher than WT. We found there existed an interaction between bHLH122 and CYP707A3 by virtue of EMSA and ChIP assays. We wanted to learn more about the molecular mechanism of bHLH122 and to explore what had changed in the over-expression plant through Genechips. Two independent overexpression bHLH122 lines and WT Arabidopsis were chosen to RNA extraction and hybridization on Affymetrix microarrays. The plants were sowed on MS medium after 96 h stratification,then transferred into soil after one weeks. After 2 weeks, collected the shoot above the soil and extracted RNA, digested by DNaseM-bM-^EM- and hybrid on Affymetrix microarrays.

Expression data from OsEBS-transgenic rice B10201 and B10301 and control Guichao2

Project description:In rice (Oryza sativa L.), the number of panicles, spikelets per panicle and grain weight are important components of grain yield. These characteristics are controlled by quantitative trait loci (QTLs) and are derived from variation inherent in crops.The identification of different yield related QTLs facilitates an understanding of the mechanisms involved in cereal crop yield, and may have utility in improving grain yield in cereal crops. an understanding of the mechanisms involved in cereal crop yield, and may have utility in improving grain yield in cereal crops. In the present study, We cloned and characterized a large-panicle QTL, and confirmed that the newly identified gene OsEBS (enhancing biomass and spikelet number) increased plant height, leaf size and spikelet number per panicle, leading to an average of 37.62% increase in total grain yield per plant. trait loci (QTLs) and are derived from variation inherent in crops.

mRNA expression data from monkey PG-haESCs, ICSI-derived ESCs and somatic fibroblasts

Project description:Haploid cells are amenable for genetic analysis because they contain only one set of chromosomes. Here,we report the derivation of haESCs from monkey parthenogenic blastocysts. These cells, which we designated PG-haESCs (parthenogenic haploid embryonic stem cells), express classical ESC markers, are pluripotent, and can differentiate to different cell lines from all three embryonic germ layers in vivo and in vitro. We used microarrays to compare the gene expression levels among PG-haESC, ICSI-derived ESCs and female monkey somatic fibroblasts. We used ICSI-derived ESCs and somatic fibroblasts isloated from female individuals as control. Gene expression profiles of all the cell lines were analysed on an Affymetrix Rhesus Macaque array.

compare the difference of gene expression between wild type ESCs and Mll2 Knockdown ESCs

Project description:Mll2 (ALR) is a histone 3 lysine 4 trimethyltransferase to function as gene activation.In our study, we found that Mll2 is vital for proper control of proliferation and lineage differentiation of mouse ESCs, particularly towards the cardiac-specific lineages. We used microarrays to detail the global programme of gene expression to compare the difference after Mll2 knockdown in E14 cell lines. E14 cells were infected with lentiviruses expressing short hairpin RNA (shRNA) for Mll2 for 24 hours, and then puromycin was added at 2mg/ml to select for 5 days. Then collet samples of control and Mll2 knockdown E14 cells for RNA extraction and hybridization on Affymetrix microarrays.

Gene expression changes under cyclic mechanical stretch in rat retinal Muller cells

Project description:The retina is often subjected to tractional forces in a variety of conditions, for instance, pathological myopia, proliferative vitreoretinopathy. As the predominant glial element in the sensory retina, Muller cells are responsible for the homeostatic and metabolic support of retinal neurons and active players in virtually all forms of retinal injury and disease. Besides, Muller cells span the entire retinal thickness, extending from the inner to the outer limiting membranes, with cell bodies located in the inner nuclear layer and lateral processes expanding into the plexiform layers of the tissue. Because of this unique morphology, Muller cells can sense even minute changes in the retinal structure because of the mechanical stretching of their long processes or side branches. Thus, itM-bM-^@M-^Ys reasonable to infer that Muller cells also participate in ocular diseases when the retina is overstretched. In this study, we aim to investigate the whole genome regulation of Muller cells under mechanical stretching, which may help in excluding possible molecular mechanisms that would account for many retinal diseases in which the retina is often subjected to mechanical forces. We used microarrays to identify patterns of gene expression changes induced by cyclic mechanical stretching in Muller cells. Rat Muller cells were seeded onto flexible bottom culture plates and subjected to a cyclic stretching regimen of 15% equibiaxial stretching for 1 and 24 h.Muller cells cultured under the same conditions but with no applied mechanical strain were considered as the unstretched control. At each time points (1 and 24 h), three totally independent experiments (3 stretched samples and 3 control samples) were conducted. Muller cells were selected for RNA extraction and hybridization on Affymetrix microarrays. Stretch (S); Control (C)

Transcript Level Expression Profiling: anticancer pathways of Smilax Glabra rhizome extract (SW)

Project description:Find the possible signaling pathways which contribute to the cell growth inhibition effect of SW-treated AGS cells Global gene expression profiling is an ideal technique to obtain useful clues for exploration of the anticancer mechanism of SW. Through comparing microarray results between solvent- and SW-treated cells, differentially expressed genes were obtained (>1.5 fold). The microarray results were validated using real-time RT-PCR. We used the KEGG database, STRING database and GO database for further ananlysis, and therefore got the possible signaling pathways underlying the anticancer effect of SW. We analyzed total RNA samples of solvent- and SW-treated AGS cells using the Affymetrix Human Gene 1.0 ST platform. No techinical replicates were performed.
