Monoclonal antibody cancer therapy

The strategy of using monoclonal antibodies for cancer treatment was first described in the late 1970s with the promise that they could be developed into therapies that were highly specific to cancer cells, killing them with few or no side effects.

MicroRNA undermines tumor suppression

Scientists at the Whitehead Institute for Biomedical Research and the National University of Singapore have discovered the first microRNA (miRNA) capable of directly tamping down the activity of the well known tumor-suppressor gene, p53, While p53 functions to prevent tumor formation, the p53 gene is thought to malfunction in more than 50% of cancerous tumors.

Genetic mechanism in mole rats can be targeted in cancer research

"When we understand how the subterranean mole rat developed these mechanisms for survival, we may be able to understand why they are so destructive in humans," Prof. Aaron Avivi of the University of Haifa said.

Small molecules block cancer gene

Finding molecules that block the activity of the oncogene Stat 3 (signal transducer and activator of transcription) required screening literally millions of compounds, using computers that compared the structure of the cancer-causing gene to those of the small molecules, said a Baylor College of Medicine researcher in a report that appears in the current online issue of the journal PLoS One (Public Library of Science ONE).

Scientists discover key molecules that inhibit viral production

The research, led by Professor Donny Strosberg of Scripps Florida, was published on March 4, 2009, in the Journal of General Virology's advance, online edition, Papers in Press.

Researchers identify mutation that causes inflammatory bowel disease

A team of scientists at The Scripps Research Institute has linked a mouse mutation to an increased susceptibility for developing inflammatory bowel disease -- represented in humans as Crohn's disease and ulcerative colitis, which together are estimated to affect more than a million people in the United States.

New clues to pancreatic cells' destruction in diabetes

Researchers have found what appears to be a major culprit behind the loss of insulin-producing beta cells from the pancreases of people with diabetes, a critical event in the progression of the disease.

Genetic change prevents cell death in mouse model of Parkinson's disease

By shifting a normal protective mechanism into overdrive, a University of Wisconsin-Madison scientist has completely shielded mice from a toxic chemical that would otherwise cause Parkinson's disease.

Scientists discover protein critical for the growth of pancreatic cancer

Researchers at Stanford University School of Medicine have identified a protein critical for the growth of pancreatic cancer.

Study shows how defective DNA repair triggers 2 neurological diseases

Scientists at St. Jude Children's Research Hospital have teased apart the biological details distinguishing two related neurological diseases-ataxia telangiectasia-like disease (ATLD) and Nijmegen breakage syndrome (NBS).

Cancer cells pull off 'Houdini' escape to evade chemotherapy

Scientists have revealed for the first time that cancer cells can reverse a process which irrevocably commits normal cells to die, in a study published in the British Journal of Cancer.

Discovery of 'on switch' for cell death signaling mechanism

Scientists at Burnham Institute for Medical Research (Burnham) have determined the structure of the interactions between proteins that form the heart of the death inducing signaling complex (DISC), which is responsible for triggering apoptosis (programmed cell death).

How cancer cells ensure their survival

A team of researchers headed by Professor Roland Stauber of Mainz University's ENT clinic has identified a molecular mechanism used by cancer cells to "defend" themselves against chemotherapeutics in an attempt to ensure their own survival.

Receptor for prostaglandin-E2 plays key role in atherosclerosis development

Atherosclerosis - a disease that includes the buildup of fatty, cholesterol-laden lumps of cells inside the artery wall - is the underlying cause of heart attacks and strokes.

Zometa (zoledronic acid) shown to enhance chemotherapy in reducing breast tumor size

New data released demonstrates that the addition of Zometa (zoledronic acid) injection to standard chemotherapy before breast cancer surgery reduces the size of breast tumors more effectively than chemotherapy alone in women with early-stage disease.

Pralatrexate shows promise for T-Cell lymphoma

Preliminary results of a pivotal Phase 2 clinical trial of pralatrexate (PDX), a drug that partially works by mimicking folic acid, showed a complete or partial response in 27 percent of patients with recurrent or resistant peripheral T-cell lymphoma (PTCL).
