Researchers identify key protein in immune response to malaria and TB

An international team of researchers has identified a key protein involved in the immune system's response to malaria, tuberculosis (TB) and a number of other infectious diseases. The insights suggest possible new therapies to tackle these major global diseases.

DNA repair runs by the biological clock

No sooner have the clocks gone forward than scientists have shed new light on the link between our biological clocks and DNA damage repair processes, essential in protecting our cells from cancer.

Immune response to cancer stem cells may dictate cancer's course

Although stem cells hold incredible promise in the fight against certain diseases, in cancer they're anything but helpful. In fact, mounting evidence is showing that a tumor's growth and spread may depend on 'cancer stem cells,' which comprise only a very small subset of the tumor.

Circadian genes may be involved in bipolar disorder

Disrupt the gene that regulates the biological clocks in mice and they become manic, exhibiting behaviors similar to humans with bipolar disorder, UT Southwestern Medical Center researchers have found.

Viral protein is an effective preventative against infection

For parents, eight million cases of acute middle-ear infections every year adds up to a lot of sleepless nights and trips to the pediatrician.

Stanford brain tumor vaccine to be tested nationally

When Susan Wright learned that she had a type of fatal, rapidly growing brain cancer at age 46, her doctors at the University of Florida told her she wouldn't live more than 18 months.

Protein-coated gold electrode to test people for gluten intolerance

Drs Thomas Balkenhol and Fred Lisdat and a team at the University of Applied Sciences, Wildau, have invented the sensor that detects antibodies involved in coeliac disease.

First time observing real-time molecular interplay within ribosome

The ribosome is a kind of factory for protein in the cell, and as such has long been a prime target for drug discovery. Now, a technological advance by a team at Weill Cornell Medical College is poised to revolutionize research in the field.

New dimension to understanding of p53 protein

The p53 protein routinely shuts down damaged cells and is one of our main lines of defence against cancer. Scientists at Karolinska Institutet in Sweden now present new findings on how p53 carries out this all-important function.

Curry related compound shows promise against Kennedy's disease

Scientists who focus on the molecular signaling that underlies prostate cancer have discovered a compound that shows promise against a debilitating neurodegenerative condition known as Kennedy's disease, which is caused by a mutant gene.

Treating sleep apnea with continuous positive airway pressure reduces incidence of stroke

Patients with moderate to severe sleep apnea who have significantly higher serum levels of inflammatory markers that serve as precursors to coronary artery disease, as well as lesions associated with silent brain infarction, have an elevated risk of stroke, according to a group of Japanese medical researchers.

Inflammation plays key role in the metastasis of prostate cancer

Many would assume that "mounting an immune response" or "having your body fight the cancer" is a good thing.

Protein podocalyxin changes the shape and adhesive quality of tumour cells

New non-toxic and targeted therapies for metastatic breast and ovarian cancers may now be possible, thanks to a discovery by a team of researchers at the University of British Columbia.

Scientists decipher a signaling pathway crucially involved in Crohn's disease and ulcerative colitis

Inflammatory bowel diseases, such as Crohn's disease and Ulcerative Colitis, severely impair the lives of more than four million people worldwide. The development of effective therapies against these diseases requires an understanding of their underlying molecular mechanisms.

Protein duo maintains communication among nerves

Frustration gave way to satisfaction when an experiment that seemed to foil St. Jude researchers actually brought them a step closer to understanding how the brain maintains healthy lines of communications among its nerves.

New anti-cancer target in enzyme MAP4K3

Scientists working at the Institute for Cancer Research have found a new anti-cancer target in MAP4K3, an enzyme which is able to 'switch on' the growth-promoter mTOR.

Discovery of new cell involved with cancer

Scientists have discovered a new type of cell that appears to play a role in the development of cancer – a highly volatile, precancerous stem cell that can either remain benign or become malignant, depending upon environmental cues.

Tykerb (lapatinib) - new anti-cancer treatment approved

The Food and Drug Administration (FDA) has approved Tykerb (lapatinib), a new targeted anti-cancer treatment, to be used in combination with capectabine (Xeloda), another cancer drug, for patients with advanced, metastatic breast cancer that is HER2 positive (tumors that exhibit HER2 protein).

Researchers uncover genetic sequence responsible for rare form of pancreatic cancer

Pancreatic ductal adenocarcinoma is an almost uniformly fatal disease regardless of the stage at time of diagnosis. However, a small percentage of patients develop a form of ductal adenocarcinoma associated with cystic lesions that can be detected earlier, is less aggressive and has a 50 percent long-term survival rate.

Two novel therapies for multiple myeloma

Two novel biologics are currently being investigated for their potential benefit to multiple myeloma patients in separate ongoing clinical trials at NewYork-Presbyterian Hospital/Weill Cornell Medical Center.
