Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

Powerful new tools can study glycans’ function

Scientists at The Scripps Research Institute have developed chemical compounds that can make key modifications to common sugar molecules ("glycans"), which are found on the surface of all cells in our body. The new study presents powerful new tools for studying these molecules' function, for example in cell signaling and immunity, and for investigating new treatments for chronic inflammation, autoimmune diseases, cancer metastasis, and related conditions.

Study uncovers mechanism by which Notch pathway could contribute to RA

A new study led by researchers at Hospital for Special Surgery identifies the mechanism by which a cell signaling pathway contributes to the development of rheumatoid arthritis (RA). In addition, the study provides evidence that drugs under development for diseases such as cancer could potentially be used to treat RA.

Treatment with IL-12 triggers T cell exhaustion in cancer patients

Rather than stimulating immune cells to more effectively battle cancerous tumors, treatment with the protein interleukin-12 (IL-12) has the opposite effect, driving these intracellular fighters to exhaustion, a Mayo Clinic study has found.

Cell-based test to discover molecules for treatment of ER-positive breast cancer

Cancer Research UK and its commercial arm, Cancer Research Technology have developed a unique test to discover molecules that could lead to potential new treatments for oestrogen receptor (ER)-positive breast cancer.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Researchers identify fibronectin strain-sensitive probes

Fibronectin plays a major role in wound healing and embryonic development. The protein, which is located in the extracellular matrix of cells, has also been linked to pathological conditions including cancer and fibrosis.

BCCA, UBC scientists identify new breast cancer genes

Scientists at the BC Cancer Agency and University of British Columbia have identified new breast cancer genes that could change the way the disease is diagnosed and form the basis of next-generation treatments.

More insight into tangled proteins in Alzheimer's disease

In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically increased what they know about this particular regulatory system in mice. Such information will help scientists better understand Alzheimer's and other diseases in humans and could eventually provide new targets for therapies.

First study to examine links between neurodevelopmental disorders and maternal metabolic conditions

A major study of the relationships between maternal metabolic conditions and the risk that a child will be born with a neurodevelopmental disorder has found strong links between maternal diabetes and obesity and the likelihood of having a child with autism or another developmental disability.

UH to host 'Science Impacting Health and Society' lecture series

A new lecture series at the University of Houston (UH) will give Houstonians an opportunity to learn how science is making a difference in health and medicine. The first of five lectures will be held from 7 to 8 p.m. Wednesday, April 25 at the Hilton University of Houston.

Drugs that target cholesterol pathway may enhance cancer-killing potential of chemotherapy drugs

Johns Hopkins investigators are testing a way to use drugs that target a cholesterol pathway to enhance the cancer-killing potential of standard chemotherapy drugs. Their tests, in mouse models of pancreatic cancer, may yield new and more effective combinations of current and possibly new anti-cancer drugs.

Study sheds light on cellular mechanisms involved in flu resistance

Scientists from the University of Utah School of Medicine have discovered that a mouse protein called IFITM3 contributes to the body's defense against some types of viral infections by binding to an enzyme responsible for regulating the pH of a cell's waste disposal system.

MEK1 mutation does not necessarily make BRAF mutant melanomas resistant to inhibitors

A second mutation found in the tumors of patients with BRAF-mutated metastatic melanoma does not contribute to resistance to BRAF inhibitor drugs, a finding that runs counter to what scientists expected to be true.

Researchers pinpoint new mechanism that potently activates T-cells in leprosy

UCLA researchers pinpointed a new mechanism that potently activates T-cells, the group of white blood cells that play a major role in fighting infections.

Researchers show how errant form of LYP can disrupt the immune system

Autoimmune diseases, such as Type I diabetes and rheumatoid arthritis, are caused by an immune system gone haywire, where the body's defense system assaults and destroys healthy tissues. A mutant form of a protein called LYP has been implicated in multiple autoimmune diseases, but the precise molecular pathway involved has been unknown.
