RNA-Methylation-Dependent RNA Processing Controls the Speed of the Circadian Clock

Circadian rhythms are the physiological changes that follow a roughly 24-hour cycle, such as the sleep-wake cycle. They are found in most living things including animals, plants and fungi. The mammalian circadian biological clock regulates metabolism via a negative transcription-translation feedback loop of clock genes. Histone protein methylation is an epigenetic modification which has been suggested to … Continue reading RNA-Methylation-Dependent RNA Processing Controls the Speed of the Circadian Clock

Histone Modifications and Epigenetic Regulation Could Hold the Key to Reversing Aging

Epigenetics has numerous connections to the process of aging, research hinting at the association between longevity and factors such as transcriptome length and DNA methylation patterns. Clearly, understanding the molecular controls of aging proves to be an intriguing endeavor as we try to interpret the clues of how we might slow down and perhaps even reverse aging. … Continue reading Histone Modifications and Epigenetic Regulation Could Hold the Key to Reversing Aging

Exploring the Possibility of Extending Lifespan Using Epigenetic Drift

Nearly a century ago, researchers discovered that cutting calorie intake was actually able to extend lifespan in various animal species. Although numerous studies have been conducted since to find out exactly why reducing calories can extend lifespan, scientists have been unable to pinpoint the answer. Now, a group of investigators at the Lewis Katz School … Continue reading Exploring the Possibility of Extending Lifespan Using Epigenetic Drift

Quercetin, a flavonoid found in many foods, has anti-aging and anti-cancer properties

Many plants, including fruits and vegetables, are known for their medicinal properties. These properties come from active compounds called metabolites that plants produce either through metabolism or to aid in that process. Plant metabolites exhibit different activities; while some are able to fight inflammation or kill microbes, others can effectively halt oxidation and delay cellular aging. According to … Continue reading Quercetin, a flavonoid found in many foods, has anti-aging and anti-cancer properties

Maybe She’s Born With it, Maybe it’s Epigenetics: 5 Tips for Beauty and Anti-Aging

We might say a beautiful woman is born with her looks or that she was endowed with good genes. But what if some of her beauty comes from reversible marks on top of her genes? The epigenetic tags on her DNA might be contributing to her glowing skin, young complexion, and silken hair. Interestingly, there may even … Continue reading Maybe She’s Born With it, Maybe it’s Epigenetics: 5 Tips for Beauty and Anti-Aging

Accurately Telling the Age of Human Tissues and Cells by DNA Methylation Clock

External signs of the human body’s age can be given by wrinkles and graying hair. However, these signs may not be accurate to tell the age of human tissues and cells that construct your body. Geneticist and biomathematician Steve Horvath at the University of California Los Angeles has developed a multi-tissue predictor of age that enables … Continue reading Accurately Telling the Age of Human Tissues and Cells by DNA Methylation Clock

Short-Term Sleep Loss Alters DNA Methylation of Clock Genes

Sleep is crucial to our well-being and helps in the process of learning and memory formation. Without proper sleep we can feel moody, irritable, and have difficulty solving problems. We can even be less creative when we don’t get enough sleep. Now, research published in the Journal of Clinical Endocrinology and Metabolism is showing us that just … Continue reading Short-Term Sleep Loss Alters DNA Methylation of Clock Genes

Certain Ethnic Groups May Epigenetically Age Slower

Scientists have been curious about whether race or ethnicity directly impact molecular markers of aging. Could people of certain race be more likely to age faster or slower? A group of researchers from UCLA conducted a study that was the first of its kind, demonstrating that Latinos actually age more slowly than other ethnic groups. … Continue reading Certain Ethnic Groups May Epigenetically Age Slower

Menopause and Insomnia Might Epigenetically Speed Up Aging

For years, scientists have disagreed on whether menopause causes aging or aging leads to menopause, giving rise to a “which came first” debate. New epigenetic research may help settle this long-standing disagreement, offering evidence that menopause might actually make a woman age faster. Two recent UCLA studies show that menopause and its common side effect … Continue reading Menopause and Insomnia Might Epigenetically Speed Up Aging

Epigenetic Clock Destines Some to Age Faster Regardless of Lifestyle

Certain people will age quicker and die sooner, even if they keep their body healthy, suggests a largescale analysis by UCLA scientists. Regardless of how well you take care of yourself, an accelerated internal epigenetic clock may lead to an earlier death for some. Researchers assessed data from over 13,000 individuals, measuring levels of DNA … Continue reading Epigenetic Clock Destines Some to Age Faster Regardless of Lifestyle
