Researchers discover mechanisms behind BRCA1 gene mutations in breast and ovarian cancer

It is widely known that mutations in the breast cancer susceptibility 1 (BRCA1) gene significantly increase the chance of developing breast and ovarian cancers, but the mechanisms at play are not fully understood. Now, researchers at Virginia Commonwealth University Massey Cancer Center have shown that certain BRCA1 mutations result in excessive, uncontrolled DNA repair, which challenges the prior assumption that mutations in BRCA1 only contribute to breast cancer through a reduction in function.

Study: Growth hormone helps regenerate damaged hair cells in zebrafish ear

Loud noise, especially repeated loud noise, is known to cause irreversible damage to the hair cells inside the cochlea and eventually lead to deafness. In mammals this is irreversible, however both birds and fish are able to re-grow the damaged hair cells and restore hearing.

Discovery in rare disease may shed light on common causes of blindness

In a rare eye disease, the retina degenerates because light-receiving cells fail to regenerate, research led by a student at Case Western Reserve University School of Medicine shows.

Contraceptive pill prevents loss of eye sight

Scientists at University College Cork (UCC) have shown that the active component (Norgestrel) of the contraceptive 'Mini Pill' prevents the loss of sight in mice that have degenerative eye conditions that normally lead to blindness.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

Two ALS-associated genes work in tandem to support long-term survival of motor neurons

Although several genes have been linked to amyotrophic lateral sclerosis (ALS), it is still unknown how they cause this progressive neurodegenerative disease. In a new study, Columbia University Medical Center (CUMC) researchers have demonstrated that two ALS-associated genes work in tandem to support the long-term survival of motor neurons.

Older dads have a higher risk of having kids with mental disorders: Study

According to a new study children of older fathers have genetic changes associated with autism and other brain disorders. As of now this is seen only in lab mice. Professor John McGrath of the Queensland University’s Brain Institute and colleagues report their findings today in the journal Translational Psychiatry.

Gene variants can cut risk of Parkinson's disease

An international team of researchers led by neuroscientists at Mayo Clinic in Florida has found a genetic variation they say protects against Parkinson's disease. The gene variants cut the risk of developing the disease by nearly 20 percent in many populations.

Parental stress strongly associated with DNA methylation in children

Researchers at the University of British Columbia and the Child & Family Research Institute have shown that parental stress during their children's early years can leave an imprint on their sons' or daughters' genes - an imprint that lasts into adolescence and may affect how these genes are expressed later in life.

Viewpoints: Spotlight on insurance industry; local health costs rising; obesity debate

The GOP candidate's positions are not a vision of the future for the U.S. but of a discredited past. ... Perry's proposed fixes for the healthcare system -; tort reform, individual ownership of health insurance, portability of plans for people who move or change jobs -; would do nothing to slow the growth of healthcare costs or reduce the number of uninsured Americans.

New insights into Lafora disease

Short-term energy storage in animal cells is usually achieved through the accumulation of glucose, in the form of long and branched chains, known as glycogen. But when this accumulation happens in neurons it is fatal, causing them to degenerate. This neuronal deterioration and death associated with glycogen accumulation is the hallmark of an extremely rare and progressive type of epilepsy known as Lafora disease (LD).

Pfizer's Xalkori receives FDA approval to treat late-stage NSCLC patients with abnormal ALK gene

The U.S. Food and Drug Administration today approved Xalkori (crizotinib) to treat certain patients with late-stage (locally advanced or metastatic), non-small cell lung cancers (NSCLC) who express the abnormal anaplastic lymphoma kinase (ALK) gene.
