Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

Epigenetic alterations drive late-onset Alzheimer's disease

New findings suggest that late-onset Alzheimer's Disease is driven by epigenetic changes -- how and when certain genes are turned on and off -- in the brain. Results were published today in Nature Genetics.

Scientists identify a novel approach to regulate cell plasticity

Cell plasticity is a property by which a cell can take on different and reversible identities. Cell plasticity is also essential for embryo development and for the correct function of the immune system.

Analysis of wild tomatoes elucidates genetic basis underlying fruit traits

Domestication and subsequent intensive breeding of tomato had a major impact on fruit ripening and the myriad metabolic processes accompanying it.

Study reveals how the loss of a protein affects proper brain development

Normal brain development requires a precise interplay between neuronal and non-neuronal (also called glial) cells. In a new study, researchers from the University of Tsukuba revealed how the loss of protein arginine methyltransferase (PRMT) 1 causes disruptions in glial cells and affects proper brain development.

ADHD study reveals genetic differences between African Americans and people of European ancestry

Researchers from Children's Hospital of Philadelphia (CHOP) have shown there may be key genetic differences in the causes of attention-deficit hyperactivity disorder (ADHD) between African Americans and people of European ancestry, which may play an important part in how patients of different ethnic backgrounds respond to treatments for this condition. The findings were published online by the journal Scientific Reports.

Genetic differences between domesticated and wild chickens linked to epigenetic changes

Some of the genetic differences that have arisen between domesticated chickens and their wild ancestors, the red junglefowl, are linked to epigenetic changes, according to a new study published in Nature Ecology & Evolution.

Zika virus infection during pregnancy can cause severe abnormalities in the fetus

Zika virus infection during pregnancy can cause severe abnormalities in the fetus, including malformations such as microcephaly. In a small proportion of cases, the disease may lead to miscarriage and perinatal death.

Study: Bacterial cells from different species can combine into unique hybrid cells

Like humans, bacteria live together in communities, sometimes lending a hand -- or in the case of bacteria, a metabolite or two -- to help their neighbors thrive.

Researchers study how bacteria adapt to their host cells

In the environment, they are often found inside unicellular organisms. A research team led by Matthias Horn at the Centre for Microbiology and Environmental Systems Science at the University of Vienna has made use of laboratory experiments to gain a better understanding of how these bacteria adapt to their host cell over time.
