Project description:We compared the genome-wide expression profiles of two yeast species (S. cerevisiae and S. paradoxus) using a two-species microarray that contain species-specific probes and can thus measure the expression levels of the two species simultaneosly. In Addition, we used the array to measure expression levels of the interspecific hybrid of these yeast species, while discriminating between the alleles that correspond to the two parental species. Comparison of the between-species differences and the within-hybrid allele differences allows us to separate cis from trans effects. Also, comparison of the overall expression in the hybrids (both alleles) with their parental species allows us to analyze hybrid over-expression and under-expression. Keywords: comparative transcriptome analysis, hybrid gene expression We analyzed four conditions (rich media, glycerol, heat shock and TSA). For each conditions, we hybridized the pooled sample of both species dyed with cy3/cy5 and a sample of the hybrid dyed with the alternate fluorescent color. Each experiment was done with 2 biological repeats, except for the rich media experiments done with 4 biological repeats.
Project description:Deletion mutants of the yeast MRX complex (Rad50, Mre11 and Xrs2) were studied for gene expression levels. Significant difference in expression levels was observed in genes pertaining to DNA damage, cell cycle etc. as compared to the BY4741 wild type.

Project description:Genomic variation is an inherent phenomena observed among members of same species belonging to different geographical locations. In case of P. falciparum, an apicomplexan protozoan parasite, its 22.8 MB nuclear genome is known to display vast genetic diversity in the subtelomeric compartments having but not exclusively variant gene families like var, rifins and stevors and examples in other elements of the genome have recently been documented. Microarrays, relies solely on the genomic sequence information to capture the relevant transcript abundance and needs to consider these variations into account for revealing true transcriptional variation.Here, we describe the designing strategy of a custom P. falciparum 15K array using Agilent platform to study the transcriptome of Indian field isolates for which genome sequence information is limited. Array contains probes representing genome sequence of two distinct geographical isolates (i.e 3D7 and HB3) and subtelomeric var gene sequence of a third isolate (IT4) known to adhere in culture condition. Probes in the array have been selected based on their efficiency to detect transcripts by performing a 244K array experiment representing multiple probes per gene/transcript. Array performance was evaluated and validated using RNA materials from P. falciparum clinical isolates obtained directly from patients with differing clinical conditions due to malaria infection.Due to pre probe screening large percentage (91 %) of the represented transcripts could be detected from Indian P. falciparum isolates. Replicated probes and multiple probes representing the same gene showed perfect correlation between them suggesting good probe performance. Additional transcripts could be detected due to inclusion of unique probes representing HB3 strain transcripts. Variant surface antigen (VSA) transcripts were detected by optimized probes representing the VSA genes of three geographically distinct strains. Plasmodium falciparum isolates were collected from patients (n=13) with differing clinical conditions. The patients exhibited symptoms categorized as uncomplicated (n=6) or complicated malaria (n=7). Criteria for determination of complicated disease were based on World Health Organization year 2000 guidelines. Microarray array based transcriptional profiling was carried out to evaluate the performance of the array.

Project description:Although a lot is known about polyamines (PAs) and their functions, scientists have not yet been able to completely understand and elucidate their mode of action and interactive molecular partners. An attempt has been made in this direction by RNAi-mediated down-regulation of a key biosynthetic gene in PA metabolic pathway, ornithine decarboxylase (ODC), under a constitutive promoter and to correlate various morphological and physiological abnormalities observed in response to reduced PA titres with a genome wide transcriptome analysis of ODC-knockdown tobacco RNAi line. The analysis has not only thrown up a number of candidate genes whose expression could be directly or indirectly affected by cellular PA levels but has also been very informative with regards to the regulation of PA pathway.
