Depression Can Alter A Person’s Circadian Clock At The Cellular Level
2013-05-14 07:16:55

redOrbit Staff & Wire Reports - Your Universe Online The circadian clock rhythms that help govern biological, hormonal and behavioral patterns in the human body are altered at the cellular level in people suffering from depression, according to new research published in the Proceedings of the National Academy of Sciences (PNAS). According to the researchers, every cell in the human body operates on a 24-hour clock, with the brain serving as the timekeeper that helps keep things...

Understanding how oncogenes affect the body clock may help create better cancer treatments The Myc oncogene can disrupt the 24-hour internal rhythm in cancer cells. Postdoctoral fellow Brian Altman, PhD, and graduate student Annie Hsieh, MD, both from the in the lab of Chi Van Dang, MD, PhD, director of the Abramson Cancer Center, Abramson Family Cancer Research Institute, Perelman School of Medicine, University of Pennsylvania, present their data in the "Metabolic Pathway Regulation in...

Prolonged Disruptions In Sleep Can Wreak Havoc On Your Genes

Brett Smith for redOrbit.com - Your Universe Online Lack of sleep has long been known to have a negative impact on a person´s physiology, but a new study from researchers at the University of Surrey in the UK has found wide-ranging genetic implications that are associated with sleep deprivation. According to the team´s report, which appeared in the journal Proceedings of the National Academy of Sciences (PNAS), the function of over 700 genes were affected by sub-standard...

When Thomas Edison tested the first light bulb in 1879, he could never have imagined that his invention could one day contribute to a global obesity epidemic. Electric light allows us to work, rest and play at all hours of the day, and a paper published this week in Bioessays suggests that this might have serious consequences for our health and for our waistlines. Daily or "circadian" rhythms including the sleep wake cycle, and rhythms in hormone release are controlled by a molecular clock...

Disruptions to the circadian rhythm can affect the growth of blood vessels in the body, thus causing illnesses such as diabetes, obesity, and cancer, according to a new study from Linköping University and Karolinska Institutet. The circadian rhythm is regulated by a “clock” that reacts to both incoming light and genetic factors. In an article now being published in the scientific journal Cell Reports, it is demonstrated for the first time that disruption of the...

Women trying to have babies also need to think about circadian clock A new Northwestern University study shows that the biological clock is not the only clock women trying to conceive should consider. The circadian clock needs attention, too. Epidemiological studies have shown female shift workers, such as nurses, and female flight attendants who work on long-distance east-west routes (i.e., those with constant jet lag) have fertility and menstrual issues. They are habitually out of...

It's no secret that long-distance, west-to-east air travel — Seattle to Paris, for example — can raise havoc with a person's sleep and waking patterns, and that the effects are substantially less pronounced when traveling in the opposite direction. Now researchers, including a University of Washington biologist, have found hints that differing molecular processes in an area of the brain known as the suprachiasmatic nucleus might play a significant role in those jet lag...
