Systems biology brings hope of speeding up drug development

Almost every day brings news of an apparent breakthrough against cancer, infectious diseases, or metabolic conditions like diabetes, but these rarely translate into effective therapies or drugs, and even if they do clinical development usually takes well over a decade.

Scientists find DNA repair 'scissors' after 18 year hunt

Cancer Research UK scientists have identified a long sought after enzyme that plays a critical role in a DNA repair pathway linked with inheritable breast and ovarian cancer, reveals research published in Nature.

Study to examine early, inherited form of Alzheimer's disease

The adult children of people diagnosed with inherited Alzheimer's disease are the focus of a new study to better understand the biology of the disease.

Common ADHD drugs do not cause genetic damage in children

In contrast to recent findings, two of the most common medications used to treat attention deficit hyperactivity disorder (ADHD) do not appear to cause genetic damage in children who take them as prescribed, according to a new study by researchers at the National Institutes of Health (NIH) and Duke University Medical Center.

Scientists discover new compounds to target muscular dystrophy

Using a drug-discovery technique in which molecules compete against each other for access to the target - the strand of toxic RNA that causes the most common form of muscular dystrophy in adults - a team at the University of Rochester Medical Center has identified several compounds that, in the laboratory, block the unwanted coupling of two molecules that is at the root of the disease.

Link found between cryptorchidism and genetic mutations

A small percentage of males born with cryptorchidism (failure of one or both testicles to descend into the scrotum), the most frequent congenital birth defect in male children, are more likely to have genetic mutations, including for a syndrome that is a common genetic cause of infertility, according to a study in the November 19 issue of JAMA .

Why are so many infectious diseases jumping from animals to humans?

Why do we have so little capacity to predict epidemics, or avoid them? Some answers, and possible solutions, can be found in the first trench-to-bench guide to wild primate infectious diseases, published Nov. 17 in the Yearbook of Physical Anthropology.

Discovery of 13 new tumor-suppressor genes in liver cancer

Over the years, hunting for cancer-related genes and understanding how they work has been an important, although time-consuming, exercise.

Kynurenic acid in brain shows potential as schizophrenia target

New research has traced elevated levels of a specific compound in the brain to problem-solving deficits in patients with schizophrenia.

Antibiotics can cause pervasive, persistant changes to microbiota in human gut

Using a novel technique developed by Mitchell Sogin of the Marine Biological Laboratory (MBL) to identify different types of bacteria, scientists have completed the most precise survey to date of how microbial communities in the human gut respond to antibiotic treatment.

Why only some former smokers develop lung cancer

Canadian researchers are trying to answer why some smokers develop lung cancer while others remain disease free, despite similar lifestyle changes.

A link found between nicotine addiction and autism

Scientists have identified a relationship between two proteins in the brain that has links to both nicotine addiction and autism.

Pain and itch regulated by different molecular mechanisms

Historically, scientists have regarded itching as a less intense version of the body's response to pain, but researchers at Washington University School of Medicine in St. Louis have determined that pain and itch actually are regulated by different molecular mechanisms.

New molecular insight into vertebrate brain development

In the December 1st issue of G&D, Dr. Fred H. Gage (The Salk Institute for Biological Studies) and colleagues reveal a role for the Hippo signaling pathway in the regulation of vertebrate neural development, identifying new factors - and potential therapeutic targets - that may be involved in congenital brain size disorders and neurological tumor formation.

New gene-silencing pathway found in plants

Biologists at Washington University in St. Louis have made major headway in explaining a mechanism by which plant cells silence potentially harmful genes.

Microarray analysis improves prenatal diagnosis

A "chip" or array that can quickly detect disorders such as Down syndrome or other diseases associated with chromosomal abnormalities proved an effective tool in prenatal diagnosis in a series of 300 cases at Baylor College of Medicine, said researchers in a report that appears in the current issue of the journal Prenatal Diagnosis.

Early detection program for men with a high prostate cancer risk

Men with a family history of prostate cancer and African-American men are particularly susceptible to the disease, with a twofold to sevenfold increased risk. Assessing risk in these populations has been difficult.
