Researchers identify molecular pathway by which Notch regulates cell proliferation in lung cancer

Lung cancer is one of the most aggressive types of cancer and the most common cause of death from this disease worldwide. Despite the progress in the molecular biology of lung cancer achieved in recent years, the mechanisms used by tumor cells to grow and spread throughout the body are not yet completely understood. This lack of information is responsible for the limited range of available therapeutic possibilities and their undesirable side effects.

BUSM part of Transthyretin Amyloidosis Cardiac Study

Researchers at Boston University School of Medicine (BUSM) have been part of a multicenter observational study called TRACS (Transthyretin Amyloidosis Cardiac Study) to help determine the health significance of a particular gene mutation which is commonly found in Black Americans.

Scientists dissect how sperm cells of the fruit fly build their flagella

Sperm swim, lung cells sweep mucus away, and the cells in the female Fallopian tube move eggs from the ovary to the uterus. Underlying these phenomena are flagella - slender, hair-like structures extending from the surface of the cells, that bend, beat or wave rhythmically. In the latest issue of the journal Developmental Cell, scientists from the Instituto Gulbenkian de Ciência (IGC), in Portugal, have dissected how sperm cells of the fruit fly build their flagella.

Researchers solve hepatitis C vaccine mystery

Researchers at the Burnet Institute have solved a hepatitis C vaccine mystery which, once developed could be the first ever preventative vaccine for the virus.

Researchers identify new gene in Cornelia deLange syndrome

Genetics researchers have identified a key gene that, when mutated, causes the rare multisystem disorder Cornelia deLange syndrome (CdLS). By revealing how mutations in the HDAC8 gene disrupt the biology of proteins that control both gene expression and cell division, the research sheds light on this disease, which causes intellectual disability, limb deformations and other disabilities resulting from impairments in early development.

Fluorescent molecules 'tag' DNA and monitor looping process

In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material in some types of cells.

Researchers discover gene mutations linked to spinocerebellar ataxia

A global hunt for the cause of a crippling inherited nerve disorder has found its target. The discovery opens the door for better diagnosis and treatment of this particular disease - but also for better understanding of why nerves in the brain's movement-controlling center die, and how new DNA-mapping techniques can find the causes of other diseases that run in families.

Latrepirdine demonstrates new potential against neurodegenerative conditions

The second of two studies on latrepirdine, recently published in Molecular Psychiatry, demonstrates new potential for the compound in the treatment of Alzheimer's disease, Parkinson's disease, sleep disorders, and other neurodegenerative conditions. An international team led by Mount Sinai School of Medicine scientists found that latrepiridine, known commercially as Dimebon, reduced the level of at least two neurodegeneration-related proteins in mice.

Epigenetic factors involved in treatment-resistance to schizophrenia drugs

Researchers at Mount Sinai School of Medicine may have discovered why certain drugs to treat schizophrenia are ineffective in some patients. Published online in Nature Neuroscience, the research will pave the way for a new class of drugs to help treat this devastating mental illness, which impacts one percent of the world's population, 30 percent of whom do not respond to currently available treatments.

New class of polymers resistant to bacterial attachment

Using state-of-the-art technology scientists at The University of Nottingham have discovered a new class of polymers that are resistant to bacterial attachment. These new materials could lead to a significant reduction in hospital infections and medical device failures.

Chronic nerve pain: researchers identify which sensory nerve cells are responsible

New research, led by academics at the University of Bristol and published in the journal Pain, has identified the subtypes of sensory nerve cells that are likely to contribute to long-term nerve pain from partial nerve injury. It is hoped this will aid in development of more effective pain killers.

Orally effective FluCide anti-influenza drug candidate

NanoViricides, Inc. announced today that an anti-influenza drug candidate under its FluCide program is effective when given orally. The Company has received information that a FluCide drug candidate designed for oral administration has shown very strong efficacy in corresponding animal studies.

Researchers uncover how pathological cells activate themselves in chronic lymphocytic leukaemia

Researchers in the group of Prof. Dr. Hassan Jumaa, Centre for Biological Signalling Studies (BIOSS) of the University of Freiburg, Department for Molecular Immunology, have identified a new mechanism that causes immune cells to convert into malignant cancer cells.

New 3-D view of the body's response to infection

A new 3-D view of the body's response to infection - and the ability to identify proteins involved in the response - could point to novel biomarkers and therapeutic agents for infectious diseases.

Insight into ubiquitin system

A faulty gene linked to a rare blood vessel disorder has led investigators to discover a mechanism involved in determining the fate of possibly thousands of proteins working inside cells.

Leukoaraiosis modifies brain function in the elderly

Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly.

Study investigates why organisms retain seemingly unnecessary stages in their development

Why, after millions of years of evolution, do organisms build structures that seemingly serve no purpose? A study conducted at Michigan State University and published in the current issue of The American Naturalist investigates the evolutionary reasons why organisms go through developmental stages that appear unnecessary.

Johns Hopkins CIDR receives NIH contract to study genetic diseases

The Johns Hopkins Center for Inherited Disease Research (CIDR) program contract, which provides up to $101 million in research funding from the National Institutes of Health (NIH) to study the genetic contribution to human diseases, has been renewed for another five years.

Scientists discover why major depression or chronic stress can cause loss of brain mass

Major depression or chronic stress can cause the loss of brain volume, a condition that contributes to both emotional and cognitive impairment. Now a team of researchers led by Yale scientists has discovered one reason why this occurs - a single genetic switch that triggers loss of brain connections in humans and depression in animal models.
