Abstract

Nuclear receptors (NRs) compose a large family of transcription factors that operate at the interface between genes and environment, acting as sensors and effectors that translate endocrine and metabolic cues into well-defined gene expression programs. We report here on a systematic quantitative and anatomical expression atlas of the 49 NR genes in 104 regions of the adult mouse brain, organized in the interactive MousePat database. MousePat defines NR expression patterns to cellular resolution, a requirement for functional genomic strategies to understand the function of a highly heterogeneous and complex organ such as the brain. Using MousePat data, NR expression patterns can be clustered into anatomical and regulatory networks that delineate the role of NRs in brain functions, like the control of feeding and learning/memory. Mining the MousePat resource will improve the understanding of NR function in the brain and elucidate hierarchical networks that control behavior and whole body homeostasis.

Nuclear receptor
In the field of molecular biology, nuclear receptors are a class of proteins responsible for sensing steroids, thyroid hormones, vitamins, and certain other molecules. These intracellular receptors work with other proteins to regulate the expression of specific genes thereby controlling the development, homeostasis, and metabolism of the organism. Nuclear receptors bind directly to DNA regulating the expression of adjacent genes; hence these receptors are classified as transcription factors.
Brain
A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons.
Transcription factor
In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence. The function of TFs is to regulate—turn on and off—genes in order to make sure that they are expressed in the desired cells at the right time and in the right amount throughout the life of the cell and the organism.
