Arabidopsis ATH1 Genome Array was used to study the expression levels of 22,500 probe-sets representing 24,000 genes. Both wild type and different transgenic lines were allowed to grow for one month under normal condition was taken for expression analysis. These plants were treated with half strength of Hoagland solution supplemented with 200mM NaCl in pots for seven days for salinity treatment. High quality RNA was extracted from the healthy leaf samples using TRI Reagent (Ambion, INC. USA) and pooled from at least four independent stressed and non-stressed samples separately, and treated with DNase-I (QIAGEN GmbH, Germany). RNA cleanup was carried out using RNeasy Plant Mini Kit (QIAGEN GmbH, Germany) and 5µg of total RNA from each sample with three biological replications were reverse-transcribed to double stranded cDNA using the GeneChipR One-Cycle cDNA Synthesis Kit. The biotin-labelled cRNA was made using the GeneChipR IVT Labelling Kit (Affymetrix, CA, USA). Twenty microgram of cRNA samples was fragmented and was hybridized for 16 hours at 45°C to the Affymetrix Arabidopsis ATH1 Genome Array (Santa Clara, CA, USA). After washing and staining with R-phycoerythrin streptavidin in a Fluidics Station, using the GenechipR Fluidics Station 450, the arrays were scanned by the GenechipR 3000 Scanner. The chip images were scanned and extracted using default settings and the .CEL files were generated using Affymetrix GeneChip Command Console (AGCC) Software.<br></br>Atleast two ATH1 Genome Array was used for hybridisation for each group of samples.

View SamplesHigh quality RNA was extracted from the whole seedlings (Combined root and leaf samples) using TRI Reagent (Ambion, Inc. USA) and pooled from 12 independent stressed and non-stressed plant samples separately, and treated with DNase-I (QIAGEN GmbH, Germany). Subsequently, RNA cleanup was carried out using RNeasy Plant Mini Kit (QIAGEN GmbH, Germany) and 5 ug of total RNA from each sample in triplicates were reverse-transcribed to double stranded cDNA using the GeneChipᆴ One-Cycle cDNA Synthesis Kit. The biotin-labelled cRNA was made using the GeneChipᆴ IVT Labelling Kit (Affymetrix, CA, USA). Twenty microgram of cRNA samples was fragmented and out of which which 7.5 ug cRNA were hybridized for 16 hours at 45C to the Affymetrix GeneChipᆴ Rice Genome Array (Santa Clara, CA, USA). After washing and staining with R-phycoerythrin streptavidin in a Fluidics Station, using the Genechipᆴ Fluidics Station 450, the arrays were scanned by the Genechipᆴ 3000 Scanner. The chip images were scanned and extracted using default settings and the CEL files were produced with the Affymetrix GeneChip Operating Software (GCOS 1.2). The resulting .CEL files were imported into the GeneSpring GX 10 (Agilent Technologies Inc, Santa Clara CA) and normalized with the PLIER16 algorithm. The resulting expression values were log2-transformed. Average log signal intensity values of three technical replicates for each sample were used for advance analysis.

View SamplesThe temporal expression profile of Glycine max seeds was carried out to identify genes that are differentially expressed (DE) during seed development. Using the Affymetrix chip, we have for the first time provided a holistic view of the transcriptional landscape during seed development in four different developmental stages in Glycine max. cv. Pusa 16. The analysis of the differential expression patterns and functional category enrichment of DE genes highlighted specific and common significant coordination and enrichment of various biological processes during seed development which have led to the identification of few candidate genes related to inositol metabolism and especially in phytate biosynthesis.

View SamplesAllyl alcohol is a highly toxic industrial chemical used as a synthetic substrate, and as an herbicide in agriculture. It is evident that Allyl alcohol is metabolized by alcohol dehydrogenases (ADH) to the highly toxic Acrolein. Acrolein is a simple unsaturated aldehyde, ubiquitous environmental pollutant, endogenous metabolite and major constituent of cigarette smoke. Acrolein is highly electrophilic in nature and has strong reactivity towards nucleophiles present in cell such as amino acids, proteins and DNA.

View SamplesValproic acid (VA) is a small-chain branched fatty acid, widely used as anticonvulsant, and mood stabilizer to treat psychiatric illness. Valproic acid is also known to inhibit the histone deacetylases (HDACs), which makes it as a potent antitumor agent in alone or in combination with other cytotoxic drugs. Beside its conventional activities, valproic acid reported to have much broader, complicated effects and affect many complex physiological processes. However the molecular mechanisms of valproic acid are unclear.

View SamplesKP1019 (trans-[tetrachlorobis(1H-indazole) ruthenate(III)]) is a ruthenium complex that exhibited anti-cancer activity in several in vitro and in vivo studies. KP1019 was even efficient against cancer cells that were resistant to other chemotherapeutic agents and thus emerged as a promising anti-cancer drug without dose-limiting cytotoxicity. However, the molecular mechanisms of its action are elusive.

View SamplesIn Saccharomyces cerevisiae, Sen1 is a 252-kDa, nuclear superfamily-1 RNA/DNA helicase that encoded by an essential gene SEN1 (Senataxin). It is an important component of the Nrd1p-Nab3p-Sen1p (NRD1) complex that regulates the transcriptional termination of most non-coding and some coding transcripts at RNA polymerase pause sites. Sen1 specifically interacts with Rnt1p (RNase III), an endoribonuclease, and with Rpb1p (Rpo21p), a subunit of RNA polymerase II, through its N-terminal domain (NTD), which is a critical element of the RNA-processing machinery. Moreover, mutations in the N-terminal tail of SETX, a human ortholog of yeast Senataxin (Sen1) reported in neurological disorders.
Sen1, the homolog of human Senataxin, is critical for cell survival through regulation of redox homeostasis, mitochondrial function, and the TOR pathway in Saccharomyces cerevisiae.
