Olfactory receptor gene expression in tiger salamander olfactory epithelium

Journal of Comparative Neurology, 2004
AbstractPhysiological studies of odor‐elicited responses from the olfactory epithelium and bulb in the tiger salamander, Ambystoma tigrinum, have elucidated a number of features of olfactory coding that appear to be conserved across several vertebrate species.

Structured spike series specify gene expression patterns for olfactory circuit formation

Science, 2019
Temporal code underlies circuit formation Olfactory neurons respond to various odorants according to which olfactory receptors, of many, they express. During development, axons from olfactory neurons that express the same olfactory receptor converge to ...

Olfactory receptor gene repertoires in mammals

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2007
In mammals, olfaction is mediated by two distinct organs that are located in the nasal cavity: the main olfactory epithelium (MOE) that binds volatile odorants is responsible for the conscious perception of odors, and the vomeronasal organ (VNO) that binds pheromones is responsible for various behavioral and neuroendocrine responses between individuals

Genome-wide Identification and Characterization of Olfactory Receptor Genes in Common Carp (Cyprinus carpio).

Gene, 2021
The environment contains a large extent of chemical information, which could be detected as olfactory sense. Olfactory in vertebrates plays important roles on many aspects during life time, including localizing prey or food, avoiding predators, mating ...

Olfactory imprinting is correlated with changes in gene expression in the olfactory epithelia of the zebrafish

Journal of Neurobiology, 2006
Odors experienced as juveniles can have significant effects on the behavior of mature organisms. A dramatic example of this occurs in salmon, where the odors experienced by developing fish determine the river to which they return as adults. Further examples of olfactory memories are found in many animals including vertebrates and invertebrates.

Expression of Olfactory-Related Genes in the Olfactory Epithelium of an Alzheimer’s Disease Mouse Model

Journal of Alzheimer's Disease, 2022
Using an amyloid precursor protein (App) gene knock-in (KI) mouse of Alzheimer’s disease (AD), we investigated the expression of olfactory-related genes in olfactory impairment caused by AD. We observed the change in olfactory behavior in the App-KI mice.

Comparative gene expression profiling of olfactory ensheathing cells from olfactory bulb and olfactory mucosa

Glia, 2010
AbstractOlfactory ensheathing cells (OEC) have the ability to promote regeneration in the nervous system. Hence, they hold promise for cell therapy. Most of the experimental studies have investigated the role of OECs taken from olfactory bulb (OB). However, for a clinical human application, olfactory mucosa (OM) seems to be the only acceptable source ...

Olfactory Receptor Gene Regulation

1998
The mammalian olfactory system recognizes and discriminates a vast array of odorant ligands . The number of odors that can be distinguished is on the order of tens of thousands. Recognition is accomplished, initially, by members of a family of 1000 odorant receptors. Thus the olfactory system rivals the immune system in its ability to recognize a large

Distribution of olfactory receptor genes in the human genome

Nature Genetics, 1998
We demonstrate that members of the olfactory receptor (OR) gene family are distributed on all but a few human chromosomes. Through FISH analysis, we show that OR sequences reside at more than 25 locations in the human genome. Their distribution is biased for terminal bands.

Polymorphisms in olfactory receptor genes: a cautionary note

Human Immunology, 2000
The hundreds of human olfactory receptor (OR) genes are organized into clusters occurring on nearly every chromosome. Although their sequences are not always closely related, they share stretches of considerable similarity, both at the amino acid and nucleotide levels.
