Chromatin remodeling complex connected to DNA damage control

When molecular disaster strikes, causing structural damage to DNA, players in two important pathways talk to each other to help contain the wreckage, scientists at The University of Texas M. D. Anderson Cancer Center report in the August edition of Cell.

Immunity in social amoeba suggests ancient beginnings

Finding an immune system in the social amoeba (Dictyostelium discoideum) is not only surprising but it also may prove a clue as to what is necessary for an organism to become multicellular, said the Baylor College of Medicine researcher who led the research that appears in the journal Science.

Lithium promotes better bone healing

Researchers at The Hospital for Sick Children (SickKids) have found a molecular pathway that plays a critical role in bone healing and have found that the drug lithium can improve the healing process.

Eat a good diet and exercise to live longer

The traditional prescriptions for a healthy life sensible diet, exercise and weight control extend life by reducing signaling through a specific pathway in the brain, according to Howard Hughes Medical Institute researchers who discovered the connection while studying long-lived mice.

Phosphatidylglycerol holds promise for psoriasis, age-related skin damage

The body may hold a secret to normalizing skin cell growth that is over zealous in psoriasis and non-melanoma skin cancers and too slow in aging and sun-damaged skin, researchers say.

New model for signal transduction in cells

Among the key communication systems within a cell is the Wnt signaling pathway, which regulates embryonic development and whose deregulation can also contribute to cancer development.

Scientists show protein accelerates breast cancer progression in animal models

The study is being published in an advanced online edition of the Proceedings of the National Academy of Sciences.

PINK1 protects from Parkinson's

Parkinson disease (PD) is a common neurodegenerative disease characterized by the selective loss of midbrain dopaminergic neurons.

New cellular pathway that operates to restrict inflammation and immunity

Jonsson Cancer Center have discovered a novel anti-inflammatory cell signaling pathway that may serve as a vital Yin-Yang mechanism to maintain the delicate balance of immune response.

Mouse hibernation hormones described

A key hormone enables starving mice to alter their metabolism and “hibernate” to conserve energy, revealing a novel molecular target for drugs to treat human obesity and metabolic disorders, UT Southwestern Medical Center researchers have found.

Check and balance for neuron activity provides insight into schizophrenia, seizures

Two genes important for human development and implicated in cancer and schizophrenia also help keep a healthy balance between excitation and inhibition of brain cells, researchers say.

Clearer view of synaptic plasticity

Scientists are keenly studying how neurons form synapses--the physical and chemical connections between neurons--and the "pruning" of neural circuits during development, not least because synaptic abnormalities may partially underlie many developmental and neurodegenerative diseases.

New understanding of ubiquitylation

It turns out there's more than one way to skin a gene. New research from Rockefeller University suggests that two closely related DNA unpackaging mechanisms may not work the way scientists thought.

Biomira selects PX-866 as clinical development candidate

Biomira Inc. has announced that it has selected PX-866 as its next clinical development candidate.

Study improves understanding of early ovarian cancer

A new University of Michigan Medical School study sheds light on cell defects that lead to one common type of ovarian cancer and puts forth a promising new mouse model that already is being used for preclinical drug testing.

Insulin receptors play a critical role in promoting islet growth

A new Joslin-led study has identified the insulin receptor as an important protein that promotes islet cell growth in mice whose bodies are unable to use insulin properly, or are insulin resistant, a precursor to type 2 diabetes.

Fungal compound galiellalactone may combat prostate cancer

Can a substance from a fungus that grows on decaying trees provide a cure for aggressive prostate cancer? This is the hope of researchers at Lund University in Sweden.

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.

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.
