'Second hit' determines immune response against developing Burkitt's lymphoma

The human c-myc gene encodes a transcription factor (MYC) involved in the regulation of a vast number of other genes - it has been estimated that the transcription of about one in six genes is somehow under the control of MYC.

Hirano bodies may play a protective role in progression of Alzheimer's

Hirano bodies are almost indescribably tiny objects found in nerve cells of people suffering from conditions such as Alzheimer's, mad cow and Lou Gehrig's diseases. Yet for decades, researchers weren't sure if these structures helped cause the conditions or appeared after onset of the disease and had some other role.

Smoking primes the brain for cocaine addiction: Study

The study comes from the National Institute on Drug Abuse in Maryland that is the first of its kind to show how nicotine can change the brain in a way that enhances the behavioral effects of cocaine. It could help explain why so many drug-using teenagers tend to start with cigarettes and alcohol before moving on to more illegal substances.

Pharmacyclics first quarter GAAP net loss increases to $14.5M

Pharmacyclics, Inc. today reported financial results and recent developments for its fiscal first quarter ended September 30, 2011.

Mouse anti-aging study generates expert commentary

Age related changes like wrinkles, muscle wasting and cataracts could be delayed in mice, say researchers in the US. They achieved the feat by removing old cells that had stopped dividing. These accumulate naturally with age. The scientists believe their findings could eventually “really have an impact” in the care of the elderly. Experts said the results were “fascinating”, but should be taken with a bit of caution.

Common gut pathogen increases activity of SMO gene and causes colon tumors

Working with lab cultures and mice, Johns Hopkins scientists have found that a strain of the common gut pathogen Bacteroides fragilis causes colon inflammation and increases activity of a gene called spermine oxidase (SMO) in the intestine.

Eliminating senescent cells could prevent or delay onset of age-related disorders

Researchers at Mayo Clinic have shown that eliminating cells that accumulate with age could prevent or delay the onset of age-related disorders and disabilities. The study, performed in mouse models, provides the first evidence that these "deadbeat" cells could contribute to aging and suggests a way to help people stay healthier as they age.

Nicotine might prime the brain to enhance behavioral effects of cocaine

A landmark study in mice identifies a biological mechanism that could help explain how tobacco products could act as gateway drugs, increasing a person's future likelihood of abusing cocaine and perhaps other drugs as well, according to the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. The study is the first to show that nicotine might prime the brain to enhance the behavioral effects of cocaine.

Nmnat1 protein may help prevent brain damage in babies with cerebral palsy

Scientists at Washington University School of Medicine in St. Louis have shown that a protein may help prevent the kind of brain damage that occurs in babies with cerebral palsy.

TERE1 gene mutation also contributes to invasive bladder cancer

Research conducted by Dr. Jayne S. Weiss, Professor and Chair of Ophthalmology at LSU Health Sciences Center New Orleans, and colleagues has found that a defect in a gene involved in a rare disease of the cornea also contributes to the progression of invasive bladder cancer.

Thyroid researcher to receive ATA's John B. Stanbury Pathophysiology Medal

Each year, the American Thyroid Association (ATA) recognizes the outstanding research contributions of one of its members to a greater understanding of thyroid physiology or the pathophysiology of thyroid disease, with its presentation of the John B. Stanbury Pathophysiology Medal at its Annual Meeting.

Research breakthrough in lung regeneration

Scientists at A*STAR'S Genome Institute of Singapore (GIS) and Institute of Molecular Biology (IMB), have made a breakthrough discovery in the understanding of lung regeneration. Their research showed for the first time that distal airway stem cells (DASCs), a specific type of stem cells in the lungs, are involved in forming new alveoli to replace and repair damaged lung tissue, providing a firm foundation for understanding lung regeneration.

Fasudil drug shows promise against cerebral cavernous malformation

A drug treatment has been proven to prevent lesions from cerebral cavernous malformation — a brain blood vessel abnormality that can cause bleeding, epilepsy and stroke — for the first time in a new study.

Insight into role of cytokines in autoimmune diseases

Cytokines, a varied group of signaling chemicals in the body, have been described as the software that runs the immune system, but when that software malfunctions, dysregulation of the immune system can result in debilitating autoimmune diseases such as lupus, arthritis, and diabetes. Leading experts in the field of cytokine research present their most up-to-date findings and unique perspectives on the role of cytokines in autoimmune diseases in a special issue of Journal of Interferon & Cytokine Research, a peer-reviewed publication of Mary Ann Liebert, Inc.

Surgeons freeze organoid units and regenerate TESI for short bowel syndrome

Surgeons at Children's Hospital Los Angeles have conducted a study that could put regenerative tissue treatment for short bowel syndrome one step closer to the bedside. The researchers were able to successfully isolate and store organoid units and later generate tissue-engineered small intestine (TESI) in a mouse model. The groundbreaking results were presented at the 2011 Annual Clinical Congress of the American College of Surgeons.

Two proteins bind together to ignite and sustain malignant brain tumors

Two previously unassociated proteins known to be overly active in a variety of cancers bind together to ignite and sustain malignant brain tumors, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports this week in the journal Cancer Cell.

Oral laquinimod shows promise against multiple sclerosis

Teva Pharmaceutical Industries Ltd. and Active Biotech today announced the presentation of Phase III clinical and pre-clinical data, which collectively demonstrate that once-daily oral laquinimod modulates the pathological processes of multiple sclerosis to impact disease activity, disability progression and brain volume loss.
