Researchers discover new genetic defect that can lead to Leigh syndrome

In Leigh syndrome, infants are born apparently healthy only to develop movement and breathing disorders that worsen over time, often leading to death by the age of 3. The problem is that the mitochondria responsible for powering their cells can't keep up with the demand for energy in their developing brains.

Genetically modified M. smegmatis vaccine shows promise against TB

An experimental vaccine composed of a genetically modified bacterium closely related to the bacterium that causes tuberculosis (TB) has been found to protect mice against TB infection, according to a study appearing online September 4 in the journal Nature Medicine.

Breast cancer patients with BRCA1 mutation experience pCR after neoadjuvent chemotherapy

Nearly half of breast cancer patients carrying the BRCA1 gene mutation experience a complete pathological response (pCR) - the disappearance of all evidence of disease from the breast tissue and lymph nodes - regardless of disease stage after standard neoadjuvent chemotherapy, according to new research from The University of Texas MD Anderson Cancer Center.

Walnuts may prevent breast cancer

A new study has found that eating a handful of walnuts on a regular basis may reduce women’s risk of developing breast cancer. Researchers from the Marshall University observed in mice that consuming 2 ounces of walnuts each day reduced the growth of breast cancer tumors.

Gene variants that help regulate serotonin may serve as predictor of risk for PSTD symptoms

Data in a study published in the Archives of General Psychiatry suggest that certain variants of a gene that helps regulate serotonin, may serve as a useful predictor of risk for symptoms related to posttraumatic stress disorder (PTSD) following a trauma.

McMaster team demonstrates essential role of AMPK enzyme in exercise

You may think your lack of resolve to get off the couch to exercise is because you're lazy, but McMaster University researchers have discovered it may be you are missing key genes.

Biologists reveal why men's ring fingers are longer than their index fingers

Biologists at the University of Florida have found a reason why men's ring fingers are generally longer than their index fingers - and why the reverse usually holds true for women.

Researchers reveal mechanism behind how cells communicate

Cell communication is essential for the development of any organism. Scientists know that cells have the power to "talk" to one another, sending signals through their membranes in order to "discuss" what kind of cell they will ultimately become - whether a neuron or a hair, bone, or muscle. And because cells continuously multiply, it's easy to imagine a cacophony of communication.

AMT, NIH enter exclusive license agreement for use of AAV5-based gene therapy vectors

Amsterdam Molecular Therapeutics, a leader in the field of human gene therapy, today announced that it has entered into an exclusive license agreement with the US National Institutes of Health (NIH) for use of adeno-associated virus serotype 5 (AAV5)-based gene therapy vectors for liver and brain indications.

Study: No big shift toward higher fatal heart attack rates after menopause in women

Contradicting the long-held medical belief that the risk of cardiovascular death for women spikes sharply after menopause, new research from Johns Hopkins suggests instead that heart disease mortality rates in women progress at a constant rate as they age.

Researchers discover novel way to increase amounts of antibiotics

A novel way of increasing the amounts of antibiotics produced by bacteria has been discovered that could markedly improve the yields of these important compounds in commercial production. It could also be valuable in helping to discover new compounds. With the ever-growing threat from antibiotic resistance, these tools will be very useful in ensuring that we have enough of these useful compounds in the future.

Cancer cells with specific genetic defect extra susceptible to therapy that damages DNA

Using a strategy based on treating cancer cells that carry a specific genetic signature - hyper-expression of the protein Myc - with therapy that affects the stability of the cell's DNA, more effective results can be achieved.

Researchers discover gene mutation linked with lymphoedema, leukaemia

Researchers have discovered a gene that when mutated can cause lymphoedema (swollen limbs due to a failure of the lymph system), immune abnormalities, deafness and leukaemia.

Scientists purify PARP protein that shows promise against breast, ovarian cancers

CANCER RESEARCH UK scientists have succeeded in purifying a protein found in bacteria that could reveal new drug targets for inherited breast and ovarian cancers - and other cancers linked to DNA repair faults.

IKEPLUS immunization completely eliminates TB bacteria from infected tissues

A potential vaccine against tuberculosis has been found to completely eliminate tuberculosis bacteria from infected tissues in some mice. The vaccine was created with a strain of bacteria that, due to the absence of a few genes, are unable to avoid its host's first-line immune response.

Researchers discover group of mutations involved in T-cell acute lymphoblastic leukemia

An international team of researchers has found a group of mutations involved in T-cell acute lymphoblastic leukemia (T-ALL), and showed that a group of certain drugs, already in clinical use to treat other diseases, can eliminate the cells carrying these mutations.

Researchers discover new genetic defect that predisposes people to leukemia, myelodysplasia

A new genetic defect that predisposes people to acute myeloid leukemia and myelodysplasia has been discovered. The mutations were found in the GATA2 gene. Among its several regulatory roles, the gene acts as a master control during the transition of primitive blood-forming cells into white blood cells.

Einstein researchers develop tuberculosis vaccine candidate

Researchers at Albert Einstein College of Medicine of Yeshiva University report in the September 4 online edition of Nature Medicine that they have developed a tuberculosis (TB) vaccine candidate that proved both potent and safe in animal studies.
