Nanoparticles target multiple cancer genes, shrink tumors more effectively

Nanoparticles filled with small interfering RNA (siRNA) molecules targeting two genes that trigger melanoma have shown that they can inhibit the development of melanoma, the most dangerous type of skin cancer.

Universal test for genetic diseases in unborn children in the pipeline

A team of British scientists have developed a ground-breaking new test to screen for genetic diseases in unborn children.

A new role for a critical DNA repair molecule in the immune system

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.

Gene mutation in worms could further understanding of alcoholism in humans

The work follows a study carried out by Oregon Health and Science University, which suggested a link between a gene mutation in mice and tolerance to alcohol. Researchers at Liverpool have investigated this in worms, looking specifically at the role the gene plays in communication between cells in the nervous system.

CytoDyn files new IND for Cytolin

CytoDyn, Inc. has filed a new IND for a study to reconfirm dose ranging and to "prove the principle" with a randomized, double-blind placebo controlled study of Cytolin, the Company's first-in-class drug for treating HIV/AIDS. This comes 13 years after the first IND was issued for the drug.

Gene study sheds new light on lung cancer

A multi-institution team, funded by the National Human Genome Research Institute (NHGRI) of the National Institutes of Health (NIH), today reported results of the largest effort to date to chart the genetic changes involved in the most common form of lung cancer, lung adenocarcinoma. The findings should help pave the way for more individualized approaches for detecting and treating the nation's leading cause of cancer deaths.

Gene find sheds light on motor neuron diseases like amyotrophic lateral sclerosis

Scientists have identified a gene in mice that plays a central role in the proper development of one of the nerve cells that goes bad in amyotrophic lateral sclerosis, or Lou Gehrig's disease, and some other diseases that affect our motor neurons.

Researchers identify novel type of antibody that potently inhibits HIV infection

A small antibody fragment that is highly effective in neutralizing the human immunodeficiency virus (HIV) by preventing the virus from entering cells has been identified by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH).

Beyond recognizing odors, a single neuron controls reactions

Babies will smile when they catch the scent of vanilla, but a whiff of rotting meat will send them into fits. From people to mice and flies to worms, animals of all kinds are born with likes and dislikes thanks to the evolutionary wisdom collected in their genes. But new research shows that some preferences are still surprisingly flexible at even the most basic level - that of the sensory neuron itself - and that our nervous system may be even more adaptable than we thought.

Shark antibodies show potential as lifesaver from cancer

Australian scientists have discovered a potentially potent weapon in the fight against cancer in antibodies taken from shark blood.

Design of a compound that stabilizes the main natural suppressor of tumours

An interdisciplinary team of researchers, headed by Ernest Giralt at the Institute for Research in Biomedicine (IRB Barcelona) and Javier de Mendoza at the "Institut Catala d'Investigaciió Quimica" (ICIQ, Tarragona), have discovered a substance with the capacity to maintain protein p53 stable even when it presents certain mutations that promote the appearance of cancer.

Unpicking the complexity of human disease

Impressive advances in our understanding of the genetic basis of disease were outlined at the 3rd ESF Functional Genomics Conference in Innsbruck, Austria.

New maturation inhibitor drugs may help solve HIV treatment conundrum

Since AIDS was first recognized in 1981, significant advances have been made in developing an effective arsenal of drugs to manage the disease and extend patients' lives.

New properties of skin stem cells

Recent research from the Swedish medical university Karolinska Institutet reveals completely new properties of the skin's stem cells - discoveries that contradict previous findings.

HIV drug resistance spreading in China, researcher says

As HIV spreads beyond high-risk groups into China's general population, drug-resistant strains of the virus also are appearing in parts of the country, Chen Zhiwei of the AIDS Institute in Hong Kong said recently, Reuters reports.

Ultrafast photodynamics of DNA

DNA, the molecule that acts as the carrier of genetic information in all forms of life, is highly resistant against alteration by ultraviolet light, but understanding the mechanism for its photostability presents some puzzling problems. A key aspect is the interaction between the four chemical bases that make up the DNA molecule.

Abdominal venous thrombosis risk factors

Abdominal venous thrombosis may present as BCS or SVT. Hereditary and acquired risk factors have been implicated in the etiopathogenesis of abdominal venous thrombosis.

Ultra-sensitive nanoprobes help tackle MRSA

This week Nature Nanotechnology journal (October 12th) reveals how scientists from the London Centre for Nanotechnology (LCN) at University College London are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as methicillin-resistant Staphylococcus aureus (MRSA).

Battling cancer at the single cell level

New research suggests that the identification and examination of key cell signaling events required for initiation and progression of cancer might be best accomplished at the single cell level. The research, published by Cell Press in the October issue of the journal Cancer Cell, provides new insight that may lead to better diagnosis and treatment of some complex cancers.
