Stressed Fathers could epigenetically give their children high blood sugar

Could Stressed Fathers Epigenetically Give their Children High Blood Sugar?

March 1, 2016 Bailey Kirkpatrick

What if stress experienced by fathers could actually be passed down epigenetically to their children, who then experience its effects later in life? Previous research has hinted that, in mice, trauma experienced by a father leaves epigenetic marks on his sperm RNA, which is inherited by his offspring who later express the same depressive behaviors as their dad. Also, another study that investigated the devastating Quebec Ice Storm of 1998 has suggested that prenatal maternal stress could trigger distinct DNA [more…]

Epigenetic Regulation of a Single Gene Controls Drug and Stress Responses

December 2, 2014 Bailey Kirkpatrick

Researchers have found that the regulation of a specific gene located in an area of the brain linked to depression and drug addiction can reduce the way someone responds to drugs and stressful situations. A mouse study that focused on the epigenetic regulation of a single gene was carried out at the Icahn School of Medicine at Mount Sinai and was recently published in Nature Neuroscience. Earlier research supports a connection between epigenetic regulation and diseases related to depression and [more…]

Epigenetic Tags on Serotonin Transporter Gene Linked to Stress

August 6, 2014 Bailey Kirkpatrick

A new study offers an epigenetic explanation as to why some people are more reactive to stress or more vulnerable to disorders related to stress. A team of researchers at Duke University have found that methylation of a gene linked to post-traumatic stress disorder (PTSD) and clinical depression can affect how an individual reacts to threats or stress. Recently published online in the journal Nature Neuroscience, the results highlight the link between the common epigenetic mechanism of DNA methylation and [more…]

A Father’s Stress Felt for Generations

April 23, 2014 Bailey Kirkpatrick

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 their offspring, even if their offspring were not directly exposed to stress or trauma. In a recent study, Isabelle Mansuy and her colleagues at the [more…]
