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.

EA sponsors research grant to investigate specific cancers and kinase mutations

Phase II trial finds fostamatinib ineffective in RA patients not responsive to biologic agents

In a previous study, rheumatoid arthritis (RA) patients who failed to respond to methotrexate were shown to experience positive results with fostamatinib disodium (R788), an oral spleen tyrosine kinase (Syk) inhibitor that is thought to block immune cell signaling involved with bone and cartilage destruction. In the current study, RA patients who failed to respond to biologic agents were studied.

2011 Japan Prize laureates announced

The Japan Prize Foundation today announced the laureates of its 2011 Japan Prize, one of the world's most prestigious international awards in science and technology.

Acetylation complex fits like a halo over a histone

To understand the emerging science of epigenetics-a field that describes how genes may be regulated without altering the underlying DNA itself-scientists are deciphering the many ways in which enzymes act on the proteins surrounding DNA within cells.

Scientists decipher genetic code for a pancreatic cancer type

Scientists at Johns Hopkins have deciphered the genetic code for a type of pancreatic cancer, called neuroendocrine or islet cell tumors. The work, described online in the Jan. 20 issue of Science Express, shows that patients whose tumors have certain coding "mistakes" live twice as long as those without them.

Researchers discover how Ras oncogene chooses a signaling pathway

The National Cancer Institute estimates that more than 43,000 Americans were diagnosed with pancreatic cancer last year and more than 36,000 died from the disease. Despite advances in genetic science showing that the Ras oncogene is mutated in virtually all pancreatic cancers, scientists have been frustrated by the complexity of the signaling pathways in humans, which make it difficult to pinpoint potential therapeutic targets.

New study reveals measles viral gene plays key role in development of PD

A gene from the measles virus plays a key role in the development of Paget's disease of bone, according to a team of researchers led by the University of Pittsburgh School of Medicine.

Michael Cuccione Foundation donates $5 million to support childhood cancer research

The Michael Cuccione Foundation is donating $5 million to support the childhood cancer research program at the Child & Family Research Institute at BC Children's Hospital, now named the Michael Cuccione Foundation Childhood Cancer Research Program. The gift, the largest ever to cancer research at BC Children's, was announced during an event at the research institute, where the program is based.

New insights into estrogen receptor beta

Research with significant implications in the treatment and intervention of cancer and obesity has been published recently in two prestigious journals by University of Houston (UH) biochemist Dr. Jan--ke Gustafsson.

Cells that give rise to neurons maintain high levels of ROS

For years, the majority of research on reactive oxygen species (ROS) - ions or very small molecules that include free radicals - has focused on how they damage cell structure and their potential link to stroke, cardiovascular disease and other illnesses.

Scientists discover that skin cancer can spread to lungs through cell blocking activity

CANCER RESEARCH UK-funded scientists have discovered that skin cancer can spread to the lungs when a gene in an important cell communication pathway is blocked. The research is published in Cancer Cell.

Sequestering GSK3 enzyme leads to stabilization of proteins in cells

The cell signaling pathway known as Wnt, commonly activated in cancers, causes internal membranes within a healthy cell to imprison an enzyme that is vital in degrading proteins, preventing the enzyme from doing its job and affecting the stability of many proteins within the cell, researchers at UCLA's Jonsson Comprehensive Cancer Center have found.

Researchers discover recycling mechanism of signaling receptors

An international team of researchers led by Carnegie Mellon University's Manojkumar Puthenveedu has discovered the mechanism by which signaling receptors recycle, a critical piece in understanding signaling receptor function. Writing in the journal Cell, the team for the first time describes how a signaling receptor travels back to the cell membrane after it has been activated and internalized.

Exosomes derived from lymphoma, colorectal cancer patients circulated through Aethlon's Hemopurifier

Aethlon Medical, Inc., the pioneer in developing therapeutic filtration devices to address infectious disease and cancer, announced today that it has demonstrated the ability to capture immunosuppressive exosomes derived from individuals with lymphoma and colorectal cancer.

Novel adenovirus-based gene therapy for renal cell carcinoma

Researchers at Virginia Commonwealth University Massey Cancer Center and the VCU Institute of Molecular Medicine (VIMM) have developed a novel virus-based gene therapy for renal cell carcinoma that has been shown to kill cancer cells not only at the primary tumor site but also in distant tumors not directly infected by the virus. Renal cell carcinoma is the most common form of kidney cancer in adults and currently there is no effective treatment for the disease once it has spread outside of the kidney.

Synthetic derivative of curry spice can be effective neuroprotective for stroke and TBI

A synthetic derivative of the curry spice turmeric, made by scientists at the Salk Institute for Biological Studies, dramatically improves the behavioral and molecular deficits seen in animal models of ischemic stroke and traumatic brain injury.

Scientists discover Notch pathway may play a role in alcohol's protective effects

Many studies support the assertion that moderate drinking is beneficial when it comes to cardiovascular health, and for the first time scientists have discovered that a well-known molecule, called Notch, may be behind alcohol's protective effects. Down the road, this finding could help scientists create a new treatment for heart disease that mimics the beneficial influence of modest alcohol consumption.

Scientist suggests functional amino acids play a critical role in human health

Functional amino acids play a critical role in the development of both animals and humans, according to a Texas AgriLife Research scientist.

Research findings on RGL2 protein can lead to new therapeutic target for pancreatic cancer

One of the most frustrating problems faced by doctors who treat pancreatic cancer is the lack of effective therapeutic options. More than 38,000 people in the United States die of the disease each year, and new drugs and treatments are desperately needed.

Bortezomib reduces inflammation and promotes bone healing in arthritis models

A new study by Greek researchers suggests that the biologic drug bortezomib (Velcade), a proteasome inhibitor used to treat multiple myeloma (bone marrow cancer), may represent a promising treatment for rheumatoid arthritis (RA). In this study, bortezomib displayed favorable effects in an animal model of inflammatory arthritis that mimics RA, in reducing disease severity and inflammation, and promoting bone healing. Full findings of this study are published in the November issue of Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR).
