Summary of "BrainEXP: a database featuring with spatiotemporal expression variations and co-expression organizations in human brains."

Gene expression changes over the lifespan and varies among different tissues or cell types. Gene co-expression also changes by sex, age, different tissues or cell types. However, gene expression under the normal state and gene co-expression in the human brain has not been fully defined and quantified. Here we present a database named Brain EXPression Database (BrainEXP) which provides spatiotemporal expression of individual genes and co-expression in normal human brains. BrainEXP consists of 4,567 samples from 2,863 healthy individuals gathered from existing public databases and our own data, in either microarray or RNA-Seq library types. We mainly provide two analysis results based on the large dataset: (i) basic gene expression across specific brain regions, age ranges, and sexes; (ii) co-expression analysis from different platforms.

Medical and Biotech [MESH] Definitions

A form of gene interaction whereby the expression of one gene interferes with or masks the expression of a different gene or genes. Genes whose expression interferes with or masks the effects of other genes are said to be epistatic to the effected genes. Genes whose expression is affected (blocked or masked) are hypostatic to the interfering genes.

The expression of a gene in an abnormal place, or at an abnormal time in an organism. Ectopic Gene Expression is often induced artificially by genetic techniques.

Observable changes of expression in the face in response to emotional stimuli.

A winged-helix transcription factor that regulates GENE expression in metabolic tissues. It plays a role in HOMEOSTASIS of GLUCOSE and controls expression of GLUT2 PROTEIN.

The study of the relationship between NUTRITIONAL PHYSIOLOGY and genetic makeup. It includes the effect of different food components on GENE EXPRESSION and how variations in GENES effect responses to food components.
