Lower BDNF levels observed in bipolar disorder patients may lead to reduced EGR3 levels. A dysfunctional pathway impairs several biological functions, including abnormal structural brain changes and cognitive and functional decline (known as neuroprogression). Disrupted neural circuits may explain the impaired neuroplasticity and resilience, increasing vulnerability to stress and mood episodes, all well-known characteristics of BD.

A new article reveals a novel potential drug target for bipolar disorder and offers new insights into the underlying biology of this lifelong and devastating mental illness. Bipolar Disorder (BD) is a multifactorial brain disorder in which patients experience radical shifts in mood and undergo periods of depression followed by periods of mania...

“Green” sunscreens could soon be easier to make, thanks to a new laboratory method for the production of a key ingredient. Credit: Estrada Anton/Shutterstock.com

Although it’s been a tough winter for many people in the U.S., summer is coming. And that means backyard barbeques, fun on the beach and, of course, slathering on sunscreen. But one particular environmentally friendly sunscreen ingredient has been difficult to obtain – shinorine, could only be harvested from nature. Scientists now report in ACS Synthetic Biology the laboratory production of that compound.

Sunscreen is key to protecting the skin from carcinogenic UV radiation. However, some synthetic sunscreen components can accumulate in aquatic environments and potentially cause harm by acting as hormone disruptors...

“By delivering red wine antioxidants during conventional angioplasty, it may be possible to prevent excess tissue from building up and the blood vessel from narrowing again as it heals,” Dr. Dugas said.

Antioxidants found in wine have advanced stents. Antioxidant compounds found in red wine are advancing the treatment of heart disease – the leading cause of death for both men and women in the U.S. Heart disease occurs when plaque builds up within artery walls blocking the blood flow through tissues in the body, increasing the risk of a heart attack or stroke. About 630,000 people die each year from heart disease, according to the Centers for Disease Control and Prevention.

While there is no singular cure for heart disease, there are numerous forms of treatment including lifestyle chang...

The structure of human telomerase reverse transcriptase (hTERT). Human TERT contains four key domains: the telomerase essential N-terminal (TEN) domain; the TERT RNA binding (TRB) domain; the reverse transcriptase (RT) domain and the C-terminal extension (CTE) domain.

Researchers from several institutions, including, UCLA, Boston University, Stanford University and the Institute for Aging Research at Hebrew SeniorLife, analyzed blood samples from nearly 10,000 people to find that genetic markers in the gene responsible for keeping telomeres (tips of chromosomes) youthfully longer, did not translate into a younger biologic age as measured by changes in proteins coating the DNA.

DNA methylation age is a biomarker of chronological age and predicts lifespan, but its underlying molecular mechan...
