Circadian rhythm gene affects malignant breast cancer's spread

On September 23, 2016, Posted by , In Buzz, By ,,,,,,, , With No Comments

Sleep cycle interruptions may affect breast cancer formation and metastasis. Expression of a gene in the circadian rhythm pathway, Arntl2, has a significant effect on whether certain breast cancers will metastasize into additional tumors, reports Kent Hunter of the National Cancer Institute (NCI) in Bethesda, Maryland and…

Sleep tight — gene responsible for sleep deprivation and metabolic disorders identified

The sleep habits of fruit flies are remarkably similar to humans. They get most of their sleep at night, certain drugs and stimulants like caffeine can negatively affect their sleep, and if they get a lousy night’s sleep it can even affect their memory performance. But what can they…

Seasonal affective disorder is believed to be triggered by seasonal changes in daylight, with the condition most prevalent during winter months. But what makes certain people more susceptible to such changes? Researchers say they have uncovered a gene mutation that could be responsible. Researchers have uncovered the first human gene…

Caltech biologists identify gene that helps regulate sleep

On February 20, 2016, Posted by , In Buzz, By ,,,,,, , With No Comments

Caltech biologists have performed the first large-scale screening in a vertebrate animal for genes that regulate sleep, and have identified a gene that when overactivated causes severe insomnia. Expression of the gene, neuromedin U (Nmu), also seems to serve as nature’s stimulant–fish lacking the gene take longer to wake…

Estrogens alleviate hyperactivity in zebrafish with autism gene

On January 30, 2016, Posted by , In Buzz, By ,,,,, , With No Comments

Research led by UCL, Yale and University of California, San Francisco has shown that the hormone estrogen alleviates the sleep disruption experienced by zebrafish genetically designed to help understand the biology of autism spectrum disorder (ASD). The scientists set out to investigate the function of genes linked…

Snappy Sleep Stager system identifies gene related to shorter sleep
