Epigenetic changes can cause type 2 diabetes

A new study by Lund University researchers confirms that epigenetic changes can contribute to the development of type 2 diabetes. The study identified 5584 sites with differing epigenetic changes in individuals with and without the disease, as well as a key gene RHOT1 involved in insulin secretion.

How plants pass down genetic memories

Researchers have discovered how plants pass along chemical markers that instruct cells on using DNA codes, a process known as epigenetic inheritance. The study reveals the role of protein DDM1 in making way for enzymes that add regulatory marks to new DNA strands, preserving genetic controls across generations.

Higher rates of autism and attention deficit/hyperactivity disorder in American children

A recent study found that American children are experiencing higher rates of autism and attention deficit/hyperactivity disorder, with special education services increasing by 10.4%. Poor nutrition and heavy metal exposure, particularly in ultra-processed foods, are thought to be primary epigenetic factors contributing to the developme...

An epigenetic cause of miscarriages is identified and cured in mice

Researchers have identified the Xist gene as a critical regulator of fetal development in mice, leading to miscarriage and abnormal placentas when epigenetic instructions are missing. The study's findings suggest that failed Xist imprinting can be 'cured' by targeting specific genes involved in histone modifications.

Traumatizing your DNA

A Tel Aviv University researcher warns that environmental stressors like pollution and stress can alter gene expression in a way that affects the human genome. This epigenetic inheritance can be passed down to future generations, with potential long-term impacts on health.

New genetic hypothesis for the cause of autism

A new genetic hypothesis proposes that most cases of autism can be explained by a complex model for genetic malfunction, involving both inherited and de novo genetic factors. The study suggests epigenetic components, including genetic imprinting, play a major role in the etiology of autism.
