Endloser, ruhiger Schlaf: Es ist ein Gen! - WEL

  1. Das Genprotein mit der Bezeichnung hDEC2-P385R injizierte man versuchsweise Mäusen, deren Schlafbedürfnis sich daraufhin ebenfalls reduziert hat - das Kurzschläfer-Gen war entdeckt
  2. We have identified a mutation in a transcriptional repressor (hDEC2-P385R) that is associated with a human short sleep phenotype. Activity profiles and sleep recordings of transgenic mice carrying this mutation showed increased vigilance time and less sleep time than control mice in a zeitgeber time- and sleep deprivation-dependent manner. These mice represent a model of human sleep.

Science 14 Aug 2009: Vol. 325, Issue 5942, pp. 825-826 DOI: 10.1126/science.1178713 . Article; Figures & Data; Info & Metrics; eLetters; PDF; Sufficient sleep is necessary for optimal daytime performance and well-being, yet there is a large difference in how much sleep people need, ranging from less than 6 to more than 9 hours. People at all points along this range exhibit no noticeable. Sleep deprivation can impair human health and performance. Habitual total sleep time and homeostatic sleep response to sleep deprivation are quantitative traits in humans. Genetic loci for these traits have been identified in model organisms, but none of these potential animal models have a corresponding human genotype and phenotype. We have identified a mutation in a transcriptional repressor. hDEC2 P385R TG: Transgene: Tg(BHLHE41*P385R)1Yfu Location: unknown Transgene origin: Strain of Origin: Not Specified Transgene description: Transgene Type: Transgenic (Inserted expressed sequence) Mutation: Insertion Tg(BHLHE41*P385R)1Yfu expresses 1 gene.

transcriptional repressor (hDEC2-P385R) that is associated with a human short sleep phenotype. Activity profiles and sleep recordings of transgenic mice carrying this mutation showed increase Некоторым действительно требуется меньше времени на восстановление — за эту скоростную регенерацию отвечает мутация гена hdec2-p385r, связанного с регуляцией суточных ритмов SHARP1 encodes a transcription repressor factor that belongs to the Hairy/Enhancer of the Split subfamily of basic helix-loop-helix factors (bHLH). Sequence alignment shows that SHARP1 is only distantly related to these proteins with a 37-42% sequence identity within its bHLH domain. Unlike most other bHLH proteins, SHARP-1 is not expressed in neuronal progenitor cells or early differentiating.

short sleep phenotype in transgenic animals (e.g., hDEC2-P385R; He et al., 2009). However, the prevalence of genetically determined short sleep in humans remains unknown. It is plausible that short sleepers denying dysfunction also comprise individuals who may be chronically sleep deprived and would function more optimally with increased sleep. In contrast, short sleepers who report sleep. We have identified a mutation in a transcriptional repressor (hDEC2-P385R) that is associated with a human short sleep phenotype. -Ying-Hui Fu et al. Some people really are just wired to run on much less sleep. The researchers identified a gene related to short sleep in two humans and exported it to mice for study. The paper makes no mention. We present a case of an acquired short sleeper phenotype after third ventriculostomy. A 59-year-old patient suffering from chronic hydrocephalus reported an average of 7-8 h of nocturnal sleep. After surgical intervention, the patient noted a strikingly reduced sleep need of 4-5 h without consequent fatigue or excessive daytime sleepiness, but with good daytime performance and well-balanced. A mutation in transcriptional repressor hDEC2-P385R is associated with a human short sleep phenotype, according to a study in the August 14 issue of Science. Investigators found that within a small extended family, two members with the mutation had lifelong shorter daily sleep requirements than most persons. The researchers then genetically engineered mice and fruit flies to express the.

They published their first gene study (a mutation in a transcriptional repressor (hDEC2-P385R)) in Science in 2009 and two more followed this year in Neuron (a mutation in the β 1-adrenergic receptor gene) and in Science Translational Medicine (a missense mutation in a G protein-coupled neuropeptide S receptor 1 (NPSR1)). Fu and colleagues are exploring how mechanisms and pathways can help. Dreaming of a good night's sleep. By admin 8th July 2010. Drs Simon Mitchell and Daria Brennan of St John of God Hospital examine the range of sleep disorders, from the common to the more serious, and suggest treatments to address the problem. On average, we sleep the equivalent of 25 years of our life. Although sleep is poorly understood, it is the subject of intense research worldwide. We.

How come? Only about 10 years ago sleep researchers discovered that people who had inherited a particular mutation (i.e., hDEC2-P385R) in a transcriptional repressor gene called DEC2 averaged only 6.25 hours of sleep per night, while study participants lacking the mutation averaged 8.06 hours. At the time, this finding provided the first evidence that natural short sleep has, at least in some. The Transcriptional Repressor DEC2 Regulates Sleep Length in Mammals Ying He, 1Christopher R.

Dr. Fu published research in 2009 in Science magazine, detailing a gene mutation called hDEC2-P385R (often shortened to DEC2) that is associated with short sleep in humans.

The site facilitates research and collaboration in academic endeavors A mutation in a transcriptional repressor (hDEC2-P385R) was identified in two individuals with lifelong shorter daily sleep times. These subjects were from a family that were naturally short sleepers; their average sleep time was 6 h and this was a result of early awakening. Mice generated with this mutation also showed less sleep and increased vigilance time, and had alterations in sleep.
