Father’s Exposure to Phthalates Impact Epigenetic Marks on Sperm DNA

New epigenetic research conducted by scientists at the University of Massachusetts suggests that a father’s environment can affect the health of his baby via epigenetic marks in his sperm. Specifically, male exposure to phthalates, which are endocrine disruptors found in plastics, personal care products like shaving cream, and in the environment that surrounds us, were … Continue reading Father’s Exposure to Phthalates Impact Epigenetic Marks on Sperm DNA

Paternal Environmental and Lifestyle Factors Influence Epigenetic Inheritance

There is strong evidence that suggests certain environmental or lifestyle factors may lead to increased risk of developing chronic diseases. These factors such as diet, behavior, stress, exposure to pollutants, and physical activity have been known to cause epigenetic changes which may be passed down from one generation to the next. It is believed that a father’s exposure to … Continue reading Paternal Environmental and Lifestyle Factors Influence Epigenetic Inheritance

Prenatal Maternal Stress Triggers Distinct DNA Methylation Signatures in Ice Storm Babies

The Quebec Ice Storm of 1998 was a devastating time that plunged more than 3 million Quebecers into frigid darkness without electricity for as long as 45 days. Now, more than 15 years later, researchers from McGill University and the Douglas Mental Health University are finding out that the length of time a pregnant woman … Continue reading Prenatal Maternal Stress Triggers Distinct DNA Methylation Signatures in Ice Storm Babies

Epigenetic Transfer of Nutrition ‘Memory’ Ends Before Great-Grandchildren

A child is at an increased risk for developing type 2 diabetes and obesity if his or her mother was undernourished during pregnancy. This risk is caused in part by epigenetic changes thought to persist through generations, but it’s uncertain at which generation these changes stop affecting offspring. Researchers at University of Cambridge give us … Continue reading Epigenetic Transfer of Nutrition ‘Memory’ Ends Before Great-Grandchildren

Inheritance and Transmission of Epigenetic Memory Across Generations

New research has been suggesting that parents can transmit changes to their gene expression to their children. The heritable changes occur as a result of environmental stresses and are known as epigenetic modifications. A previous article covered the epigenetic transfer of nutrition “memory” across several generations. Now, a recent study by researchers from the University of California in Santa … Continue reading Inheritance and Transmission of Epigenetic Memory Across Generations

Parents Who Exercise Could Epigenetically Pass on Heightened Learning Ability to Their Children

Exercising your body and your brain are two ways to improve your own health. It’s well known that physical and mental activity can boost learning ability and reduce risk for diseases such as Alzheimer’s. But, could doing so also directly benefit your future children? New research in Cell Reports indicates that a child’s capacity for learning could … Continue reading Parents Who Exercise Could Epigenetically Pass on Heightened Learning Ability to Their Children

A Father’s Stress Felt for Generations

New scientific research suggests that the negative effects of trauma can be inherited. Fathers may actually transfer the consequences of their early experiences to their children via an epigenetic process. Researchers report that mice that experienced stress early on passed down the negative consequences – depression, underestimation of risk, and upset of metabolism – to … Continue reading A Father’s Stress Felt for Generations

High Estrogen Levels Might Epigenetically Protect Women From a Traumatic Event

Whether a woman’s estrogen level is high or low could determine if she may be susceptible to developing post-traumatic stress disorder (PTSD), according to recent research. Estrogen has been found to epigenetically change gene activity in the brain and could even protect a woman from emotional numbness, flashbacks, and difficulty sleeping – all symptoms of PTSD … Continue reading High Estrogen Levels Might Epigenetically Protect Women From a Traumatic Event

Fathers Affected by Early Life Trauma May Impact Later Generations Through Sperm MicroRNAs

When it comes to reproductive health, it’s no secret that a pregnant mother’s choices and environment can severely impact her child’s epigenetics and health—especially mothers suffering from PTSD. But it turns out fathers who have suffered significant stress early on in their life may also epigenetically impact the physical and mental health of their offspring. It was previously … Continue reading Fathers Affected by Early Life Trauma May Impact Later Generations Through Sperm MicroRNAs

Arthritic Joints May Need Different Treatments Due to Diverse Epigenetic Signatures

Arthritis is a widespread, debilitating disease characterized by inflammation of the joints. It affects at least 52 million adults in the United States – that’s more than 1 out of every 5 people, according to the CDC. Although medication has improved in recent years, the diversity in pathogenic pathways in certain types of arthritis, for example, rheumatoid … Continue reading Arthritic Joints May Need Different Treatments Due to Diverse Epigenetic Signatures
