Immunomedics reports CD22 antibody produced significant anti-tumor response

Immunomedics, a biopharmaceutical company primarily focused on the development of monoclonal antibody-based products for the targeted treatment of cancer, autoimmune and other serious diseases, today reported that epratuzumab, the Company's humanized anti-CD22 antibody, conjugated with SN-38, the active component of irinotecan, produced significant anti-tumor responses in a mouse model of human lymphoma.

Interference with biofilm detachment mechanisms may prevent biofilm-associated infections

Patients in hospitals and healthcare facilities can develop infections as a result of contamination of indwelling medical devices such as catheters with bacteria that are normal inhabitants of the skin of the patient or health care personnel. The bacterium Staphylococcus epidermidis is a major cause of such infections.

Protein alpha-2-beta-1 integrin suppresses metastasis

Mary Zutter and colleagues, at Vanderbilt University Medical Center, Nashville, have generated data that lead them to suggest that decreased expression of the protein alpha-2 integrin is predictive of tumor dissemination to distant sites and decreased survival in individuals with either breast or prostate cancer.

Closer to restoring vision loss due to optic nerve damage

Damage to the optic nerve, connecting the eye with the brain, is a major cause of blindness. The most common culprit is glaucoma, estimated to affect more than 4 million Americans. There is currently no way to restore the lost vision, because the optic nerve, like other nerves in the mature central nervous system (CNS), cannot regenerate. Now, scientists at Children's Hospital Boston report achieving the greatest regeneration to date in the mammalian optic nerve.

Gene mutation can lead to different mental illnesses when influenced by same environmental factor

Male mice born with a genetic mutation that's believed to make humans more susceptible to schizophrenia develop behaviors that mimic other major psychiatric illnesses when their mothers are exposed to an assault to the immune system while pregnant, according to new Johns Hopkins research.

Mount Sinai’s instructor receives Liz Tilberis Grant from OCRF

AnaLisa DiFeo, PhD, Instructor in the Department of Genetics and Genomic Sciences at Mount Sinai School of Medicine, has been honored by the Ovarian Cancer Research Fund (OCRF) with the Liz Tilberis Grant.

Lipids react and change to bacterial stimulus, trigger cell's immune response

For the first time, scientists have described not only the identities and quantities of fat species in a living mammalian cell in this case, a mouse macrophage or white blood cell but they also report how these lipids react and change over time to a bacterial stimulus triggering the cell's immune response.

American-style diet plays a vital role in prostate cancer, researchers say

Elevated fat and cholesterol levels found in a typical American-style diet plays an important role in the growth and spread of prostate cancer, say researchers at Thomas Jefferson University's Kimmel Cancer Center.

Diabetes plays a vital role in regulating brain cholesterol: Research

The brain contains more cholesterol than any other organ in the body, has to produce its own cholesterol and won't function normally if it doesn't churn out enough. Defects in cholesterol metabolism have been linked with Alzheimer's disease and other neurodegenerative conditions. Now researchers at Joslin Diabetes Center have discovered that diabetes can affect how much cholesterol the brain can make.

Scientists create couch potato mouse model to study muscle function

Daniel Kelly, M.D., and his colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) at Lake Nona have unveiled a surprising new model for studying muscle function: the couch potato mouse.

New strategy to prevent memory deficits in mouse model with AD

Scientists at the Gladstone Institute of Neurological Disease (GIND) in San Francisco have discovered a new strategy to prevent memory deficits in a mouse model of Alzheimer's disease (AD).

Disrupting estrogen pathway can halt expansion of breast cancer stem cells: Research

Breast cancer stem cells (CSCs), the aggressive cells thought to be resistant to current anti-cancer therapies and which promote metastasis, are stimulated by estrogen via a pathway that mirrors normal stem cell development.

Breakthrough with mutant gene that causes familial ALS

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that eventually destroys most motor neurons, causing muscle weakness and atrophy throughout the body. There is no cure and the current treatment has only a moderate effect on the march of the disease, which typically kills within three to five years. This week in PNAS, a team of Brandeis scientists reports an innovative approach to treating the most common form of familial ALS, commonly known as Lou Gehrig's disease.

Preclinical trial shows Chimerix’s CMX001 inhibits HSV replication

Chimerix, Inc., a pharmaceutical company developing orally-available antiviral therapeutics, today announced that data demonstrating preclinical efficacy of Chimerix's lead antiviral compound CMX001 against herpes simplex virus (HSV) as well as its ability to penetrate the blood-brain barrier was published in the November 15, 2010 issue of The Journal of Infectious Diseases.

FDA grants ACT clearance for Phase I/II clinical trial of hESC derived retinal cells in patients with SMD

Advanced Cell Technology, Inc. announced today that the US Food and Drug Administration (FDA) has cleared the Company's Investigational New Drug (IND) application to immediately initiate a Phase I/II multicenter clinical trial using retinal cells derived from human embryonic stem cells (hESCs) to treat patients with Stargardt's Macular Dystrophy (SMD), one of the most common forms of juvenile macular degeneration in the world. The decision removes the clinical hold that the FDA had placed on the trial.

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.

Mouse study finds blocking GnT-V enzyme delays breast cancer growth

New University of Georgia research, published this week in the early online edition of the journal Proceedings of the National Academy of Sciences, has found that blocking the action of an enzyme called GnT-V significantly delays the onset and spread of tumors in mice with cancer very similar to many cases of human breast cancer.

5-lipoxygenase protein modulates amyloid beta formation linked to Alzheimer's disease

A protein known to exist in the brain for more than 30 years, called 5-lipoxygenase, has been found to play a regulatory role in the formation of the amyloid beta in the brain, the major component of plaques implicated in the development of Alzheimer's disease, according to researchers at Temple University's School of Medicine.

Idera presents data on TLR7, TLR9 antagonist candidate for hyperlipidemia at American Heart Association

Idera Pharmaceuticals, Inc. announced today that it is presenting preclinical data from a study evaluating the mechanism of action of one of its Toll-like receptor (TLR) 7 and TLR9 antagonist candidates in a model of hyperlipidemia.

Researchers develop human cell-based model of Rett syndrome

A groundbreaking study published Friday in the leading scientific journal, Cell, revealed that a team of investigators had successfully generated nerve cells using skin cells from four individuals with Rett syndrome. The study, funded in part by IRSF, was led by Dr. Alysson Muotri at the University of California, San Diego--a leading researcher in the stem cell field.
