Summary: Researchers identify the role the Pig-Q gene plays in sleep regulation. Mutations of the Pig-Q gene increase sleep.

A research effort involving researchers from Texas A&M University, the Perelman School of Medicine at the University of Pennsylvania and Children’s Hospital of Philadelphia (CHOP) has used human genomics to identify a new genetic pathway involved in regulating sleep from fruit flies to humans—a novel insight that could pave the way for new treatments for insomnia and other sleep-related disorders.

Queen ants live far longer than genetically identical workers. Researchers are learning what their longevity secrets could mean for aging in other species.

Dr Vittorio Sebastiano presents about aging and reprogramming and answers questions from audience in this clip. He specifies short Reprogramming does not impact cellular Identity but Impact cellular age and cellular health.

Dr. Vittorio Sebastiano is an Assistant Professor in the Department of Obstetrics and Gynecology at Stanford School of Medicine. His lab has established a new technology named ERA (Epigenetic Reprogramming of Aging), which repurposes the conceptual idea of reprogramming, with the goal to promote epigenetic rejuvenation of adult cells leaving their identity untouched. This new technology was patented and is being implemented by Turn Biotechnologies, of which Dr. Sebastiano is co-founder and Chair of the Scientific Advisory Board.

The finding that these “hidden” memories can be accessed once more, at least in mice, throws up a world of intriguing possibilities.

Neuroscientist Robbert Havekes and his team at the University of Groningen found that learning while sleep-deprived does not result in memory loss; rather, it is more difficult to recall.

“We previously focused on finding ways to support memory processes during a sleep deprivation episode,” says Havekes.

Investigators at Cedars-Sinai have created a unique and detailed molecular profile of endometriosis to help improve therapeutic options for the millions of women suffering from the disease.

The study is published today in the journal Nature Genetics.

“Endometriosis has been an understudied disease in part because of limited cellular data that has hindered the development of effective treatments. In this study we applied a new technology called single-cell genomics, which allowed us to profile the many different cell types contributing to the disease,” said Kate Lawrenson, Ph.D., an associate professor in the Department of Obstetrics and Gynecology at Cedars-Sinai, and co-senior and corresponding author of the study.

Researchers have used fruit flies to decipher an unexplained connection between Alzheimer’s disease and a genetic variation, revealing that it causes neurons to die.

The findings from the Walter and Eliza Hall Institute (WEHI)-led team uncover a possible cause of neurodegeneration in the early stages of Alzheimer’s disease and open the door for the future development of new treatments for cognitive diseases.

The study, “An increase in mitochondrial TOM activates apoptosis to drive retinal neurodegeneration,” with collaborators from Australian National University, is published in Scientific Reports.

A team of researchers affiliated with multiple institutions in Canada has found that obesity in young mice can lead to inflammatory disease later in life even if the mouse is no longer overweight. In their paper published in the journal Science, the group describes studying early life obesity in test mice and the development of age-related macular degeneration. Kevin Mangum and Katherine Gallagher with the University of Michigan have published a Perspectives piece in the same journal issue outlining the research.

Age-related macular degeneration (AMD) in older people can lead to permanent blindness. Prior research has shown obesity plays a major role in its development. Other research has also shown that AMD is a neuroinflammatory condition. It is believed that the inflammation in the eyes is related to obesity, but the exact connection has not been identified. In this new effort, the researchers sought to find the connection by studying obesity and macular degeneration in mice.

The work involved feeding test mice a high-fat diet and studying the impact on adipose tissue macrophages (types of white blood cells that are part of the immune system). They found that obesity in mice led to epigenetic changes in the macrophages that resulted in an increase in expression of genes that incite an inflammatory response. They also found that the increased expression continued even after the test mice were put on a reduced diet that allowed them to return to their normal weight.

A team of scientists from the University of Pittsburgh School of Medicine has found the missing puzzle piece in the mystery of how melanoma tumors control their mortality.

In a paper published in Science, they describe how they identified the specific genetic changes that allow tumors to grow rapidly while also preventing their own death. This discovery could have significant implications for the way melanoma is understood and treated by oncologists.
