Researchers identify three genes regulating stemness of gastric tissue stem cells

Tissue stem cells can self-renew and differentiate, supplying cells necessary for tissues at various developmental stages.

Unknown root trait allows some cereal plants to grow deeper roots

A previously unknown root trait allows some cereal plants to grow deeper roots capable of punching through dry, hard, compacted soils, according to Penn State researchers, who suggest that harnessing the inherited characteristic could lead to crops better able to deal with a changing climate.

Scientists identify specific genes associated with post-traumatic stress disorder

A research team has found 18 specific, fixed positions on chromosomes (called loci) that seem to be linked to post-traumatic stress disorder (PTSD).

Mice study provides new data for studying aging and age-related diseases

A novel compound that increases lifespan in a small nematode worm has been shown to delay bone loss in aging mice.

Study shows why obese mothers tend to have children susceptible to metabolic diseases

A Brazilian study published in the journal Molecular Human Reproduction helps understand why obese mothers tend to have children with a propensity to develop the metabolic disease during their lifetime, as suggested by previous research.

Venom of Tiger Rattlesnakes may advance genetic science

Among all rattlesnake species, the Tiger Rattlesnake has the simplest yet most lethal venom. Now, a new study performed by a team of researchers can describe the genetics behind the venomous bite of the Tiger Rattlesnake.

Study shows how nonmalignant cells adapt to harsh tumor microenvironment

Cells need energy to survive and thrive. Generally, if oxygen is available, cells will oxidize glucose to carbon dioxide, which is very efficient, much like burning gasoline in your car. However, even in the presence of adequate oxygen, many malignant cells choose instead to ferment glucose to lactic acid, which is a much less efficient process.

Speciation process takes place in the presence of maximal gene flow, indicates study

Spatial isolation is known to promote speciation - but researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations.

Study sheds new light on a genetic developmental disorder

The rare hereditary developmental disorder, called Meier-Gorlin syndrome, or MGS for short, causes dwarfism, missing patella, a small brain, small ears, and other skeletal abnormalities. This condition leads to stillbirths and miscarriages in severe cases.

Scientists propose a simple model for gene regulation in higher organisms

Although the DNA and its double-helix are some of the most familiar molecules of our time, our knowledge of how cells control what genes they want to express still is rather limited. In order to create, for example, an enzyme, the information that's inscribed in our DNA about this enzyme needs to be transcribed and translated.

“Nanobiologic” immunotherapy can train the immune system to eliminate tumor cells

Until recently, it was believed that the innate immune system, the body's first line of defense, lacked the ability to remember pathogens like the adaptive immune system.

Cellular senescence variations may help control health and onset of age-related diseases

Researchers from Kumamoto University, Japan have proposed that cellular senescence variations during the aging process could lead to control of health and onset of age-related diseases.

Researchers reveal the features of T cells for treating multiple sclerosis

Multiple sclerosis (MS) is an autoimmune disorder that develops as immune cells attack the nervous system. T cells are a critical part of our immune system, with a complex array of subtypes - some drive the autoimmune response, while others try to suppress it.

Researchers unravel molecular factors that drive severity of COVID-19

While most COVID-19 cases are asymptomatic or mild, severe complications associated with acute respiratory distress have led to more than one million deaths worldwide in just several months.

Two proteins compete to give shape to plants

In an elegant choreography, plants take cues from their environment and channel them into flowers, roots, or branches.

Researchers identify gene related to seed dispersal in green millet

For years, Elizabeth (Toby) Kellogg, PhD, member and Robert E. King Distinguished Investigator and other researchers at the Donald Danforth Plant Science Center (Danforth Center) drove up and down the highways of the continental United States, occasionally pulling over to the side of the road to collect small weedy plants and bring them back to the lab.

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.

Study aims to understand how genetics and social environment influence behavior

Interactions between individuals of the same species shape many aspects of their biology, including their social behavior.

Study highlights the role of brain astrocyte cells in Parkinson's disease pathology

A new study using induced pluripotent stem cell (iPSC) technology links astrocyte dysfunction to Parkinson's disease (PD) pathology.
