Discovery provides new mechanism that could be exploited to create malaria vaccine

Scientists have revealed that immune cells called natural killer (NK) cells may play a key role in ridding the body of malaria-infected blood cells, a study in eLife reports.

MIT researchers decode structure of molecule that gives tissues their elasticity

The stretchiness that allows living tissues to expand, contract, stretch, and bend throughout a lifetime is the result of a protein molecule called tropoelastin. Remarkably, this molecule can be stretched to eight times its length and always returns back to its original size.

Canadian researchers uncover new molecular mechanism to stop proliferation of cancer cells

Canadian researchers have discovered a new and direct molecular mechanism to stop cancer cells from proliferating. In the prestigious journal Nature Cell Biology, scientists from Université de Montréal show that a disruption of a fine balance in the composition of ribosomes (huge molecules that translate the genetic code into proteins) results in a shutdown of cancer cell proliferation, triggering a process called senescence.

Oxygen-starved tumors have an Achilles' heel that could be targeted with drugs

A tumor's goal is simple: to grow, grow, grow, by making more cancer cells. But that often means growing so fast that the oxygen supply gets scarce, at which point cells within the tumor start to suffocate.

New discovery suggests potential target for treating cancers and other diseases

When cells grow and divide to ensure a biological function - such as a properly working organ - DNA must be unwound from its typical tightly packed form and copied into RNA to create proteins.

Lund researchers develop fluorescent variant of a molecule that inhibits cancer stem cells

A team of researchers at Lund University in Sweden has developed a fluorescent variant of a molecule that inhibits cancer stem cells.

Researchers use gene editing to reduce autism symptoms in mice

Researchers have used CRISPR-Cas9 gene editing to treat symptoms of autism in mice. It is hoped that the tool could one day be used to help humans.

Study: Inner nuclear envelope plays role in lipid metabolism

The cell nucleus is an organelle, in which the DNA of an organism is protected and duplicated. The nucleus of this organ-like structure in the cell plasma is surrounded by an outer and an inner nuclear envelope, which is penetrated by openings - so-called nuclear pores.

Researchers diagnose cerebral palsy using AI and next-generation sequencing

Researchers have shown that patients with spastic cerebral palsy (CP) can be identified using DNA methylation patterns in circulating blood cells.

Distek, Inc. launches revolutionary benchtop scale bioreactor

Distek, Inc. has revolutionized benchtop scale bioreactors with the release of our BIOne 1250 bioprocess control station for both mammalian and microbial models.

Study provides clues to how cancer cells develop resistance to chemotherapies

About half of all drugs, ranging from morphine to penicillin, come from compounds that are from - or have been derived from - nature. This includes many cancer drugs, which are toxic enough to kill cancer cells.

Study reveals how mTORC1-driven changes in crowding could influence major diseases

Among the most studied protein machines in history, mTORC1 has long been known to sense whether a cell has enough energy to build the proteins it needs to multiply as part of growth.

Scientists identify gene that triggers senescence

Scientists seeking to unlock the secrets of cellular aging have identified a gene that triggers senescence, a phenomenon in which cells stop dividing.

Researchers discover new type of cell that hinders formation of fat cells

Obesity is the plague of our times. Some 80 percent of obese people will develop Type 2 diabetes at some point in their lives, and being overweight is also a significant risk factor for cancer and heart attacks.

Lipid-scrambling DNA enzyme outperforms naturally occurring counterpart, say researchers

A new synthetic enzyme, crafted from DNA rather than protein, flips lipid molecules within the cell membrane, triggering a signal pathway that could be harnessed to induce cell death in cancer cells.

Study reveals new target to halt tumor growth

Researchers at the University of Wisconsin-Madison have discovered that a protein called Munc13-4 helps cancer cells secrete large numbers of exosomes - tiny, membrane-bound packages containing proteins and RNAs that stimulate tumor progression.

Scientists discover the molecular trigger of necroptosis

Researchers have uncovered a trigger for an immune-related cell death pathway called necroptosis. The discovery could be used to develop new treatments for cancer and immune disorders.
