Researchers develop new method to produce natural sweetener

A research group from Oulu University has developed a method capable of producing the natural sweetener brazzein. Production of brazzein as a good tasting sweetener has long been in development but until now, no solution for commercial production has been found.

New research to understand fundamental role of ubiquitin in cell death or survival

An effective regulation of programmed cell death is crucial for the correct development of embryos, a working innate immune system, and the prevention of cancer. How cells control the switch between cell survival and death, and which signaling pathways are involved, remain unclear.

Researchers discover how protein pair regulates cellular calcium signals

All mammalian cells need a ready supply of calcium ions to execute functions as diverse as neurotransmission, muscle contraction, hormone release, or immune responses. So fundamental is this requirement that cells protect themselves from disaster by storing calcium in a network of intracellular cisterns called the endoplasmic reticulum, or ER.

Scientists engineer antiviral peptide that exploits Achilles' heel of Zika virus

Scientists at Nanyang Technological University, Singapore have engineered an antiviral peptide that exploits the Zika virus at its Achilles' heel - the viral membrane - hence stopping the virus from causing severe infections.

Study uncovers important role of PRMT1 in dilated cardiomyopathy

In a study published in iScience, Professor Akiyoshi Fukamizu of the Life Science Center for Survival Dynamics, Tsukuba Advanced Research Alliance (University of Tsukuba, JAPAN) and the research group reported a new work on discovery of the important role of PRMT1 in dilated cardiomyopathy.

Purifying Proteins from Mammalian Cell Culture

In many cases mammalian cells are the only option to produce recombinant proteins with correct post-translational modifications, e.g. glycosylation, which are required for proper function of the therapeutic protein.

Researchers synthesize new antibacterial polymers without hydrophobic alkyl chains

Artificial polymers, like antibiotic peptides, need both hydrophobic and hydrophilic domains in their molecular structure to exert antibacterial activity.

Breakthrough study sheds light on mechanism underlying Warsaw Breakage Syndrome

Researchers from Tokyo Metropolitan University and the FIRC Institute of Molecular Oncology in Italy have uncovered a previously unknown function of the DDX11 helicase enzyme.

Supercomputer simulations reveal potential therapeutic target in HIV-1 replication

HIV-1 replicates in ninja-like ways. The virus slips through the membrane of vital white blood cells. Inside, HIV-1 copies its genes and scavenges parts to build a protective bubble for its copies.

Novel delivery system for bacteriophages could offer new way to battle lung infections

A new delivery system for bacteriophages - viruses that selectively attack harmful bacteria - could help give doctors a new way to battle lung infections that threaten older patients and people with cystic fibrosis.

Scientists discover secret to success of antiviral gene

It's been known for years that humans and other mammals possess an antiviral gene called RSAD2 that prevents a remarkable range of viruses from multiplying.

Novel approach to visualize how platelets are formed in body

Platelets are uniquely mammalian cells, and are the small cells of the blood that are critical for us to stop bleeding when we cut ourselves.

Researchers use droplet-sized 'miniecosystems' to test therapeutic potential of molecules

Scripps Research scientists have solved a major problem in chemistry and drug development by using droplet-sized 'miniecosystems' to quickly see if a molecule can function as a potential therapeutic.

Novel compound as effective as FDA-approved antibiotics for treating deadly infections

Purdue University researchers have identified a new compound that in preliminary testing has shown itself to be as effective as antibiotics approved by the Food and Drug Administration to treat life-threatening infections while also appearing to be less susceptible to bacterial resistance.

New studies on fat cell filling, history of biochemistry, and ketogenic diet

There's more than one type of fat cell. Besides the white fat that stores triglycerides in lipid droplets in preparation for lean times later, mammals also have heat-generating brown fat, which acts more like a radiator than a storage closet.

Scientists create small, self-contained spaces inside mammalian cells

How to install new capabilities in cells without interfering with their metabolic processes? A team from the Technical University of Munich and the Helmholtz Zentrum München have altered mammalian cells in such a way that they formed artificial compartments in which sequestered reactions could take place, allowing the detection of cells deep in the tissue and also their manipulation with magnetic fields.

Simplified Mammalian Cell Harvesting without Centrifuging

Centrifuging adds time and can potentially damage the cell sample, Michael Grauf discusses how cell clarification and sterile filtration can be achieved in one step.

New optogenetic tools show promise in treating cardiovascular, neuropsychiatric disorders

You've heard of "nature versus nurture," and philosophers argue about which is more important. But how does this work on the cellular level?

Biologists discover surprising, additional function for soluble form of SNARE protein

In 2013, the Nobel Prize in Physiology or Medicine was awarded to three scientists for their contributions to uncovering the mechanisms governing vesicle transport in cells. Their explanations provided both a conceptual and a mechanistic understanding of basic processes at the most fundamental level.

Researchers probe RNA epigenetics and chromatin structures to predict drug resistance in leukemia

Drug resistance is a major obstacle to effective treatment for patients with cancer and leukemia. Epigenetic modifying drugs have been proven effective for some patients with hematologic malignancies, such as myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML).
