Investigational antisense medicine lowers disease burden, reduces myeloma cell abundance in mice

Many patients with multiple myeloma, a type of blood cancer, eventually develop resistance to one treatment after another. That's in part because cancer stem cells drive the disease -- cells that continually self-renew. If a therapy can't completely destroy these malignant stem cells, the cancer is likely to keep coming back.

Study reveals genetic variants that increase the risk of nocturnal enuresis

In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis - commonly known as bedwetting or nighttime incontinence. The findings provide completely new insights into the processes in the body causing this widespread phenomenon.

Study highlights need to develop new measures to improve conservation outcomes in protected areas

Protected areas are critical to mitigating extinction of species; however, they may also be in conflict with efforts to feed the growing human population.

Global analysis of the impact of land acquisitions on local food security

Large-scale land acquisitions by foreign investors, intended to improve global food security, had little to no benefit, increasing crop production in some areas while simultaneously threatening local food security in others, according to researchers who studied their effects.

Viral relatives of SARS-CoV-2 can evolve to evade the human immune system

Scientists have shown that two species of seasonal human coronavirus related to SARS-CoV-2 can evolve in certain proteins to escape recognition by the immune system, according to a study published today in eLife.

Scientists urge global policymakers to recognize fish as a solution to food insecurity

Scientists are urging global policymakers and funders to think of fish as a solution to food insecurity and malnutrition, and not just as a natural resource that provides income and livelihoods, in a newly-published paper in the peer-reviewed journal Ambio.

Functions of gamma delta T cells are regulated by sugars and fat Gene, shows study

The team led by Bruno Silva Santos, Principal Investigator and Deputy Director of the Instituto de Medicina Molecular João Lobo Antunes (iMM) and Professor at the Faculdade de Medicina da Universidade de Lisboa, discovered that the functions of a subtype of white blood cells - gamma delta T cells - are regulated by metabolic resources, namely sugars and fat.

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.

Researchers define cancer invasion machinery orchestrated by cancer gene

Researchers at the University of Helsinki have defined a cancer invasion machinery, which is orchestrated by a frequently mutated cancer gene called Ras. When signaling from Ras protein becomes abnormally high, like it does in many cancers, this switches on the cellular machinery that helps the cancer cells to depart from the tissue from which the cells have developed.
