Abstract null null Background null A range of sleep disturbances are commonly experienced by patients with psychiatric disorders, and genome-wide genetic analyses have shown some significant genetic correlations between these traits. Here, we applied novel statistical genetic methodologies to better characterize the potential shared genetic architecture between sleep-related phenotypes and psychiatric disorders. null null null Methods null Using the MiXeR method, which can estimate polygenic ove...

The fragile X autosomal homolog 1 (Fxr1) is regulated by lithium and has been GWAS-associated with schizophrenia and insomnia. Homeostatic regulation of synaptic strength is essential for the maintenance of brain functions and involves both cell-autonomous and system-level processes such as sleep. We examined the contribution of Fxr1 to cell-autonomous homeostatic synaptic scaling and neuronal responses to sleep loss, using a combination of gene overexpression and Crispr/Cas9-mediated somatic kn...

ABSTACT In humans, there is an endogenous, near 24-hour (i.e., circadian) variation in mood with the best mood occurring during the circadian day and the worst mood occurring during the circadian night. Only positive affect, and not negative affect, has been shown to contribute to this circadian rhythm. We discovered a sharp circadian peak in negative affect during the circadian night coincident with a circadian trough in positive affect. These findings may help explain the association of depres...

eQTL analysis of human brain RNA-seq data targeted to genes within the 10q24.32 schizophrenia-associated locus reveals that the risk SNP in this region is selectively associated with expression of BORCS7 and a human-specific isoform of AS3MT across multiple independent samples. Expression of only the associated AS3MT isoform is higher in tissue from humans with schizophrenia than in healthy controls.

601 Sleep Duration, Race/Ethnicity, and SES—Whinnery et al INTRODUCTION Sleep duration is an important indicator of health. Indeed, many studies have suggested that consistently acquiring sufficient sleep is necessary for the maintenance of good health.1 However, up to 30% of Americans report only obtaining 6 or fewer hours of sleep per night,2 and based on self-report, the average nightly sleep duration in the United States may be declining.3 Both subjectively reported and objectively measured ...

In recent years, numerous studies have documented pervasive transcription across 70–90% of the human genome. This was particularly surprising because less than 2% of the total genome encodes protein-coding genes, suggesting that non-coding RNAs represent most of the human transcriptome. Recent reports indicate that aside from around 21,000 protein-coding genes, the human transcriptome includes about 9,000 small RNAs, about 10,000–32,000 long non-coding RNAs (lncRNAs) and around 11,000 pseudogene...
It has long been appreciated that sleep problems are common among those with psychiatric disorders. The prevailing view has been that sleep problems are generally symptoms of the associated psychiatric conditions. Consistent with this point of view is that sleep problems are defining features of a number of psychiatric disorders and included among the diagnostic criteria for these conditions.1 However, there are a number of additional ways that psychiatric disorders and sleep are inter-related. ...
