Effect of odor inhalation of rats with restraint stress on their hypothalamic gene expression profiles

ABSTRACT: To uncover molecular mechanisms underlying reduction of responses to restraint stress by racemic (R,S)-linalool inhalation, gene expression profiling at the hypothalamus of restraint stressed rats exposed to racemic (R,S)-linalool was carried out. Inhaled (R,S)-linalool returned the expression of 560 stress-induced probe sets to a normal status. These genes were associated with synaptic transmission via neurotransmitters including anxiolytic neuropeptides such as oxytocin and neuropeptide Y, and also included a number of major histocompatibility complex (MHC) class I necessary for neural development and plasticity. These results reveal some of the molecular mechanisms for odor inhalation under stress condition at the hypothalamus.

Effect of odorant inhalation on hypothlamic gene expression profile exposed to restraint stress in rats

Project description:As an attempt to assess physio-psychological effects elicited in odorant-inhaled rats, gene expression profiling in the central nervous system was carried out with rats housed under stressful conditions. (R)-(-)-linalool inhalation to rats during 2 h restraint significantly up-regulated the expression of genes in hypothalamus, which were found to be related to neuron differentiation and regulation of transcription as well as immediate early genes. The expressions of 104 among focused stress-regulated genes were significantly altered by the inhalation. The (R)-(-)-linalool inhalation significantly repressed the restraint-induced changes in the expression levels of 77 of the 104. It also promoted the expression of the remaining 27 genes including those related to anti-apoptotic heat shock proteins. The differences in their hypothalamic gene expressions revealed that the inhaled odorants actually influenced stress responses, based on the restraint-induced hypothalamic gene expressions related to apoptosis. These results indicate that the analysis of gene expression profiles in rats subjected to a stressful condition is useful to evaluate odorant-induced effects as shown by the particular results that (R)-(-)-linalool inhalation under only 2 h restraint- stressed condition induces neuron differentiation against apoptosis.

Biomarkers of hippocampal gene expression in a mouse restraint chronic stress model

Project description:Acute stress provides many beneficial effects whereas chronic stress contributes to a variety of human health problems. The objective of this study was to use a rodent model to uncover hippocampal gene signatures associated with prolonged chronic stress which could potentially serve as biomarkers and therapeutic targets for early diagnosis and pharmacological intervention for stress induced disease. Mice were subjected to restraint stress over 7 consecutive days and gene expression changes in the hippocampus were analyzed at 3, 12 and 24 hours following the final restraint treatment. Data indicated that mice exposed to chronic restraint stress exhibit a differential gene expression profile compared to non-stressed controls. The greatest differences were observed 12 and 24 hrs following the final stress test.

Acquisition of Innate Odor Preference Depends on Spontaneous and Experiential Activities During Critical Period

Project description:Animals possess inborn ability to recognize certain odors to avoid predators, seek food and find mates. Innate odor preference has been thought to be genetically hardwired. Here we report that acquisition of innate odor recognition requires spontaneous neural activity and is influenced by sensory experience during early postnatal development. Genetic silencing of mouse olfactory sensory neurons during the critical period has little impact on odor sensitivity, discrimination and recognition later in life. However, it abolishes innate odor preference and alters the patterns of activation in brain centers. Moreover, exposure to an aversive odor during the critical period abolishes aversion in adulthood in an odor specific manner. The loss of innate aversion is associated with broadened projection of OSNs. Thus, a delicate balance of neural activity is required during critical period in establishing innate odor preference and ectopic projection is a convergent mechanism to alter innate odor valence
