Transcriptomics

RNA-seq with next-generation sequencing (NGS) has become the method of choice for researchers interested in characterizing genome-wide gene and transcript expression in a single experiment.

RNA-seq is widely used for profiling expression of protein-coding and non-coding transcripts (small and long) in both model species (human, mouse, Arabidopsis, maize, etc.) with well-defined transcriptome, and species with no reference transcriptome. RNA-Seq methods can provide precise measurement of gene and transcript levels, determine strand orientation, map alternate transcripts with high confidence, characterize gene fusions, identify single nucleotide variants and help discover novel gene isoforms.

RNA-seq has been utilized for diverse application areas in biology. For example, in pathobiology of cancer to dissect the link between tumor genotypes and molecular subtypes of cancer, to aid in tumor classification and progression, and to characterize multiple drug susceptible tumorigenic pathways towards discovering new biomarkers or therapeutic strategies. In agriculture, RNA-seq methods have been used to assess transcript diversity across different varieties, characterize mode of action of trait genes, and discover new genes or targets for crop/trait improvement (yield and other agronomic traits, disease resistance, insect tolerance, quality traits, etc).

Tertiary analysis of expression datasets is necessary to understand affected genes and pathways and this is typically accomplished through differential expression analysis, enrichment analysis, and co-expression based network analysis, to create a global picture of cellular function.

Our integrated data solutions lets you manage and explore your primary expression data, as well as outputs from tertiary analysis tools. Explore data outputs from transcriptome characterization tools by simply uploading your expression matrix or results from differential expression analysis. Search over your data, subset your data, perform statistical analysis and visualize the data.
