Homolog genes are genes descending from a common ancestral DNA sequence. Homolog genes in different species (i.e., genes that evolved from a common ancestral gene by speciation) are referred to as ortholog genes and usually retain a very similar function…

Some Bioconductor-based projects may be computationally challenging and require a lot of resources. If a powerful workstation is not available, it may be a good idea to work with R and Bioconductor at scale using Amazon Web Services (AWS). Setting…

This page describes a quick way to extract gene expression information for a specific group of genes (as defined in one or more GO terms) from a Oncomine DataSet. This is useful, for example, if we want to study a…

Gene Expression Omnibus (GEO) is an online public repository of functional genomics data. Information about GEO may be found at the following URL: http://www.ncbi.nlm.nih.gov/geo/info/faq.html. Briefly, GEO includes different types of datasets: GEO Profiles are curated datasets obtained from GEO DataSets….

RNAseq data may provide an estimate of the relative expression level of different genes in a sample or in a cell type. It is sufficient to compare RPKM (reads per kilobase trascript per million reads) values of the genes of…
