Researchers reveal cellular origin of PIK3CA-induced breast tumors

In a study published in Nature, researchers lead by Cédric Blanpain, MD/PhD, WELBIO investigator and Professor at the Université libre de Bruxelles, Belgium, in collaboration with Pr Wayne Phillips, Australia and Pr Christos Sotiriou, Bordet Institute, Belgium, uncovered the cellular origin of PIK3CA-induced breast tumors and demonstrated that the cancer cell of origin controls tumor heterogeneity and is associated with different breast tumors types and clinical prognosis.

Northwestern University researchers identify molecular difference in male and female brains

Male and female brains operate differently at a molecular level, a Northwestern University research team reports in a new study of a brain region involved in learning and memory, responses to stress and epilepsy.

Netrin1 protein acts as cellular "marriage broker"

Scientists at the Montreal Neurological Institute and Hospital -The Neuro, at McGill University and the McGill University Health Centre, have made a breakthrough in understanding an important protein that appears to act as a kind of cellular "marriage broker."

Researchers identify potential drug target to fight TB

The U.S. Food and Drug Administration recently approved the first new drug to fight tuberculosis (TB) in more than 40 years, but treatment still takes six months, 200 pills and leaves 40 percent of patients uncured. Thus, new targets are needed. Today in ACS Central Science, researchers report they have identified one such target -- a gene that allows the disease to camp out in human immune cells, and is thus essential for the organism's proliferation.

FGF protein may play key role in breast and prostate cancer, shows research

Simply put, cancer is caused by mutations to genes within a cell that lead to abnormal cell growth. Finding out what causes that genetic mutation has been the holy grail of medical science for decades.

Study suggests that eye movements during REM sleep responsible for resetting dream 'snapshots'

Rapid Eye Movement (REM) sleep, the period in which we experience vivid dreams, was discovered by scientists in the 1950s. Because REM sleep is associated with dreaming, on the one hand, and eye movement, on the other, it has been tempting to assume that each movement of the eye is associated with a specific dream image. But despite decades of intense research by leading international scientists, this intuitive hypothesis has remained unproven.

Molecular on-off switch controls how mouse brain responds to vision loss

KU Leuven biologists have discovered a molecular on-off switch that controls how a mouse brain responds to vision loss.

Higher-fit kids have significantly thinner gray matter, better mathematics achievement than their low-fit peers

A new study reveals that 9- and 10-year-old children who are aerobically fit tend to have significantly thinner gray matter than their "low-fit" peers. Thinning of the outermost layer of brain cells in the cerebrum is associated with better mathematics performance, researchers report in the journal PLOS ONE.

First clinical trial to test use of retinal progenitor cells for treating retinitis pigmentosa begins

Participants are being enrolled in the first clinical trial that tests the use of retinal progenitor cells to treat retinitis pigmentosa, reported project director Dr. Henry Klassen of UCI's Gavin Herbert Eye Institute and Sue & Bill Gross Stem Cell Research Center. The product of stem cell research at UCI, these retinal progenitors are similar to stem cells in terms of potential regenerative properties, but they're specific to the retina.

Tumor cells associated with pancreatic cancer work with each other to increase tumor spread

Tumor cells associated with pancreatic cancer often behave like communities by working with each other to increase tumor spread and growth to different organs. Groups of these cancer cells are better than single cancer cells in driving tumor spread, according to new research from the Perelman School of Medicine at the University of Pennsylvania published in Cancer Discovery online in advance of the print issue.

Researchers identify novel brain network that plays wide role in memory and learning processes

One of the more heartbreaking realities of Alzheimer's is the moment when a loved one struggling with the disease no longer fully recognizes a family member or close friend who is caring for them.

Study suggests potential target for treating familial form of ALS

A healthy motor neuron needs to transport its damaged components from the nerve-muscle connection all the way back to the cell body in the spinal cord. If it cannot, the defective components pile up and the cell becomes sick and dies. Researchers at the NIH's National Institute of Neurological Disorders and Stroke have learned how a mutation in the gene for superoxide dismutase 1 (SOD1), which causes ALS, leads cells to accumulate damaged materials.

New research could help develop precision medicine for primary aldosteronism

Each of your kidneys wears a little yellow cap that helps keep your blood pressure in check, and much more. But in some people, it starts running amok, pumping out a hormone that sends blood pressure sky-high.

Common marker can help identify patients at high risk for deadly cardiac events

A marker commonly used to determine if a patient is having a heart attack can also be used to identify stable patients at high risk for deadly cardiac events, according to a new study led by investigators at Brigham and Women's Hospital.
