Drugs designed to lower alpha-ketoglutarate levels could help fight DIPG tumors

Every year, 150 to 300 children in the United States are diagnosed with diffuse intrinsic pontine gliomas (DIPGs), aggressive and lethal tumors that grow deep inside the brain, for which there are no cures.

Study shows DNA damage causes cells to reprogram themselves into stem cells

Researchers have discovered that when DNA in the moss Physcomitrella patens is damaged, it causes cells to reprogram on their own to change into stem cells.

Study shows how mitochondrial defects lead to neurodevelopmental diseases

The tiny organelles mitochondria supply the energy crucial for all cells in the human body, specifically in the brain that consumes an excessive amount of fuel.

Study shows how proteins act as a defense mechanism to protect their own DNA

Viruses usually inject their DNA into a host cell to multiply. As soon as this foreign material penetrates the intracellular fluid, it activates a defense mechanism called the cGAS-STING pathway.

High-speed AFM enables real-time visualization of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses.

Switching off 'master regulator' may offer neuroprotection from Parkinson's-related damage

Switching off a molecular "master regulator" may protect the brain from inflammatory damage and neurodegeneration in Parkinson's disease, reports a study published today in Nature Neuroscience.

Regulating cancer stemness using combination of nanotechnology and genetic engineering

The development of chemotherapeutic agents with selective anti-cancer activities is increasingly unattractive due to the emergence of resistance, poor targeting of cancer tissues, and subsequent metastasis.

Rotating microscope can track and measure behavior of ocean organisms

Like spirits passing between worlds, billions of invisible beings rise to meet the starlight, then descend into darkness at sunrise. Microscopic plankton's daily journey between the ocean's depths and surface holds the key to understanding crucial planetary processes, but has remained largely a mystery until now.

Novel receptor protein can be a promising treatment for COVID-19

A novel receptor protein that binds to the SARS-CoV-2 virus and prevents it from entering cells may hold promise for treating COVID-19 and other coronavirus-related diseases, according to research published online Aug. 4 in the journal SCIENCE.

Researchers show how two X chromosomes communicate during embryo development

Researchers at Massachusetts General Hospital (MGH) have solved a mystery that has long puzzled scientists: How do the bodies of female humans and all other mammals decide which of the two X chromosomes it carries in each cell should be active and which one should be silent?

SIDT1 in the mammalian stomach mediates absorption of dietary miRNAs

In a new study published in Cell Research, Chen-Yu Zhang's group at Nanjing University School of Life Sciences, China, reports that SIDT1 in the mammalian stomach mediates host uptake of dietary and orally administered microRNAs (miRNAs), thus exerting biological functions in the host.

NIH-supported research delineates how genetic variations cause atopic dermatitis

New research supported by the National Institutes of Health delineates how two relatively common variations in a gene called KIF3A are responsible for an impaired skin barrier that allows increased water loss from the skin, promoting the development of atopic dermatitis, commonly known as eczema.

Study reveals why immunity boost from seasonal flu vaccines is not long lasting

A study from Emory Vaccine Center provides insights into why the boost in immunity from seasonal flu vaccination lasts for months but not years, unlike some childhood vaccinations.

Hydrogels based on modified pectins could be used for neural tissue restoration

Far Eastern Federal University (FEFU) scientists have developed implantable hydrogels based on plant polysaccharides (pectins). They can play the role of an artificial extracellular matrix, a special network of molecules that fills the space between body cells.
