Researchers focus on phosphoinositide 3-kinase pathway in cancer research

Researchers are taking a closer look at the phosphoinositide 3-kinase (PI3-kinase) pathway as studies continue to demonstrate that inhibiting this biological route suppresses tumor growth, reports Genetic Engineering & Biotechnology News (GEN ).

Dormant stem cells for emergencies

Many specialized cells, such as in the skin, intestinal mucosa or blood, have a lifespan of only a few days.

Stem cells derived from bone marrow may offer novel therapeutic option for epidermolysis bullosa

Stem cells derived from bone marrow may serve as a novel therapeutic option to treat a disease called epidermolysis bullosa (EB), a disorder characterized by extraordinarily fragile skin, according to a study prepublished online in Blood, the official journal of the American Society of Hematology.

Two simple blood tests detect flesh-eating bacteria

With less than half of patients with necrotizing soft tissue infections displaying the physical signs of these very serious infections, researchers have found two simple blood tests can help physicians diagnose what is commonly known as "flesh-eating bacteria," according to a study in the December issue of The American Journal of Surgery.

Moderate alcohol intake boosts amount of omega-3 fatty acids in our body

Moderate alcohol intake is associated with higher levels of omega-3 fatty acids in plasma and red blood cells.

Doing the math for membranes

Determining the mechanisms that shape biological membranes has long been a tricky business. Like a factory assembly line, eukaryotic cells are organized into membrane-bound, functional compartments called organelles.

Cancer stem-cell model tested by University of Michigan researchers

One of the most promising new ideas about the causes of cancer, known as the cancer stem-cell model, must be reassessed because it is based largely on evidence from a laboratory test that is surprisingly flawed when applied to some cancers, University of Michigan researchers have concluded.

Scientists show that endothelial cells give rise to blood stem cells

Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels.

Scientists film immune cell becoming infected by a parasite

Forget what's number one at the box office this week. The most exciting new film features the intricate workings of the body, filmed by scientists using ground-breaking technology.

Natural killer T cells play important role in Lyme disease

A research team led by the La Jolla Institute for Allergy & Immunology and Albany Medical College has illuminated the important role of natural killer (NK) T cells in Lyme disease, demonstrating that the once little understood white blood cells are central to clearing the bacterial infection and reducing the intensity and duration of arthritis associated with Lyme disease.

Discovery of new enzyme in cancer growth

While studying the mechanics of blood clots, researchers at the University of Oklahoma Health Sciences Center discovered a new enzyme that not only affects the blood, but seems to play a primary role in how cancer tumors expand and spread throughout the body.

Tobacco plants grown in novel mist bioreactor system provide new soure of interleukin-12

Interleukin-12 is a naturally occurring protein essential for the proper functioning of the human immune system.

Anti-oestrogen drugs may promote more harmful cancer cell behaviour

The authors found that tamoxifen can promote an invasive phenotype in ER+ breast cancer cells under conditions of poor cell-cell contact, a previously unknown effect of this drug

New set of controls for stem cells discovered

Natural changes in voltage that occur across the membrane of adult human stem cells are a powerful controlling factor in the process by which these stem cells differentiate, according to research published by Tufts University scientists.

Motor neurons derived from human embryonic stem cells provide insight into ALS

Two new research studies use motor neurons derived from human embryonic stem (hES) cells to demonstrate that multiple toxic pathways contribute to the devastating degeneration associated with Amyotrophic Lateral Sclerosis (ALS) and that protective therapeutics will need to oppose the disease on multiple fronts.

Genetic breakdown in Fanconi anemia may have link to HPV-associated cancer

A genetic malfunction that causes DNA instability in people with the blood disorder Fanconi anemia may put them at high risk for squamous cell carcinomas linked to human papillomavirus (HPV), according to a study posted online ahead of print by Oncogene.

Gene therapy used to alleviate sickle cell disease pathology

Using a harmless virus to insert a corrective gene into mouse blood cells, scientists at St. Jude Children's Research Hospital have alleviated sickle cell disease pathology.

New insights into cellular senescence

Scientists have identified a molecular cause behind the ravages of old age and in doing so have also shown how a natural process for fighting cancer in younger persons can actually promote cancer in older individuals.

Broccoli compound, indole-3-carbinol targets key enzyme in late-stage cancer

An anti-cancer compound found in broccoli and cabbage works by lowering the activity of an enzyme associated with rapidly advancing breast cancer, according to a University of California, Berkeley, study appearing this week in the online early edition of the journal Proceedings of the National Academy of Sciences.
