In the field of molecular biology, gene expression profiling is the measurement of the activity (the expression) of thousands of genes at once, to create a global picture of cellular function. These profiles can, for example, distinguish between cells that are actively dividing, or show how the cells react to a particular treatment.
Tools for querying and downloading gene expression profiles are provided. Human Protein Atlas (HPA [10]): a public database with expression profiles of human protein coding genes both on mRNA and protein level in tissues, cells, subcellular compartments, and cancer tumors. Legume Information System (LIS): genomic database for the legume family [11]
It helps identify main proteins in a particular sample, and those proteins differentially expressed in related samples—such as diseased vs. healthy tissue. If a protein is found only in a diseased sample then it can be a useful drug target or diagnostic marker. Proteins with the same or similar expression profiles may also be functionally ...
Data can be queried for specific proteins and genes, browsed based on organism, tissue, localization and condition, and sorted by false discovery rate and expression. MOPED empowers users to visualize their own expression data and compare it with existing studies.
The RNA expression profile of the GLUT4 Transporter (one of the main glucose transporters found in the human body) Profiles like these are found for almost all proteins listed in Wikipedia. They are generated by organizations such as the Genomics Institute of the Novartis Research Foundation and the European Bioinformatics Institute.
The Expression Atlas allows searches by gene, splice variant, protein attribute, disease, treatment or organism part (cell types/tissues). Individual genes or gene sets can be searched for. All datasets in Expression Atlas have its metadata manually curated and its data analysed through standardised analysis pipelines.
Once the genotypes are known, the individual's genotype can be compared with the published literature to determine likelihood of trait expression and disease risk. Helps in Personalized Medicine Electromics: Branch of genomics concerned with the role of exogenous electric fields in potentiating the gene expression profiles of cells, tissues ...
Protein expression may refer to: Gene expression , the processes that convert the information of DNA genes into a functional copies of mRNA in living cells Protein production , the method of generating some quantity of a specific protein in biotechnology
