Lithocholic acid can kill several types of cancer cells

Lithocholic acid (LCA), naturally produced in the liver during digestion, has been seriously underestimated. A study published in the journal Oncotarget shows that LCA can kill several types of cancer cells, such as those found in some brain tumors and breast cancer.

Study reveals factors associated with prevention, control of HIV infection

New vaccine research in monkeys suggests that scientists are homing in on the critical ingredients of a protective HIV vaccine and identifies new HIV vaccine candidates to test in human clinical trials.

Scientists determine structure of endomannosidase enzyme

Scientists have determined the structure of the enzyme endomannosidase, significantly advancing our understanding of how a group of devastating human viruses including HIV and Hepatitis C hijack human enzymes to reproduce and cause disease.

RNF123 gene may play a role in major depression

Psychiatric disorders can be described on many levels, the most traditional of which are subjective descriptions of the experience of being depressed and the use of rating scales that quantify depressive symptoms. Over the past two decades, research has developed other strategies for describing the biological underpinnings of depression, including volumetric brain measurements using magnetic resonance imaging (MRI) and the patterns of gene expression in white blood cells.

Stem cell like progenitor cells could be key to aging slowly: Study

In new research on mice, scientists have found that stem cells could help slow the aging process. This new research was conducted on mice that had been bred to have progeria, a disorder that causes premature aging. Mice with the condition typically live only 21 to 28 days instead of the usual two years.

Researchers identify key ingredient needed for muscles to grow

We take it for granted, but the fact that our muscles grow when we work them makes them rather unique. Now, researchers have identified a key ingredient needed for that bulking up to take place. A factor produced in working muscle fibers apparently tells surrounding muscle stem cell "higher ups" that it's time to multiply and join in, according to a study in the January Cell Metabolism, a Cell Press journal.

Emerging forms of torture cause serious mental health problems

Use of torture around the world has not diminished but the techniques used have grown more complex and sophisticated, according to new research from Queen Mary, University of London.

PEDF may suppress brain from tumor-induced damage, metastasis

Scientists are one step closer to repairing the damage caused by brain metastasis, a major challenge in cancer treatment, according to data published in Cancer Research, a journal of the American Association for Cancer Research.

Amyloid precursor protein fragment may be a biomarker for autism

Immune system abnormalities that mimic those seen with autism spectrum disorders have been linked to the amyloid precursor protein (APP), reports a research team from the University of South Florida's Department of Psychiatry and the Silver Child Development Center.

Research reveals how bats parse duties at single neuron level

Imagine listening to music while carrying on a conversation with friends. This type of multi-tasking is fairly easy to do, right? That's because our brains efficiently and effectively separate the auditory signals - music to the right side; conversation to the left. But what researchers have not been able to do in humans or animals is to see a parsing of duties at the single neuron level - until now.

Shorter Chk1 protein neutralizes longer sibling to potentially benefit cancer patients

Scientists have found at least one instance when the smaller sibling gets to call the shots and cancer patients may one day benefit.

Genomic architecture predisposes supercentenarians to age-related diseases

The first-ever published whole-genome sequences of not just one, but two supercentenarians, aged more than 114 years, reveal that both unusual and common genetic phenomena contribute to the genetic background of extreme human longevity.

Study reveals possibility to selectively target and block crucial microRNA in liver cancer

A new study shows that it is possible to selectively target and block a particular microRNA that is important in liver cancer. The findings might offer a new therapy for this malignancy, which kills an estimated 549,000 people worldwide annually.

Researchers discover culprit that leads from heart failure to diabetes

Either heart failure or diabetes alone is bad enough, but oftentimes the two conditions seem to go together. Now, researchers reporting in the January Cell Metabolism appear to have found the culprit that leads from heart failure to diabetes and perhaps a novel way to break that metabolic vicious cycle.

Losartan may help prevent smoking-related COPD

Working with mice, scientists at Johns Hopkins have successfully used a commonly prescribed blood pressure medicine, losartan (Cozaar), to prevent almost all of the lung damage caused from two months of exposure to cigarette smoke. The treatment specifically targeted lung tissue breakdown, airway wall thickening, inflammation and lung over-expansion.

Cardiff University technique could help predict IVF embryos with best success chances

A new technique successfully used in mice to identify embryos likely to result in a successful pregnancy could be used in humans, potentially boosting IVF success rates and helping to reduce the number of multiple births, according to Cardiff University scientists.

Researchers identify candidate genes for histiocytoid cardiomyopathy

Researchers are closing in on a rare genetic disorder causing a heart condition in infants. Histiocytoid cardiomyopathy (HC) often causes sudden death before a child reaches 2 years of age. Gene analysis is helping to narrow the many theories surrounding the genetic basis of HC.

Young stem/progenitor cells improve health and life of progeria mice

Mice bred to age too quickly seemed to have sipped from the fountain of youth after scientists at the University of Pittsburgh School of Medicine injected them with stem cell-like progenitor cells derived from the muscle of young, healthy animals.

BioTime to market muscle progenitor cell lines bearing hereditary diseases

BioTime, Inc. today announced that it has elected to market progenitors of muscle stem cells bearing hereditary diseases. BioTime will produce the products from five human embryonic stem (hES) cell lines from Reproductive Genetics Institute (RGI) of Chicago, Illinois.

Alteration in ISG15 pathway triggers breast cancer metastasis

Research led by Shyamal Desai, PhD, Assistant Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, has discovered a key change in the body's defense system that increases the potential for breast cancer to spread to other parts of the body.
