Genetic Testing Doesn't Cause Undue Worry for Breast Cancer Patients

Genetic testing for breast cancer has become more complex. Newer tests now evaluate a panel of multiple genes, compared to older tests looking only at BRCA genes. The new complexity often brings more uncertainty about the results. But, a new study finds that these more extensive tests are not causing […]

Anti-Inflammatory Compound Protects Against Cancer Growth and Recurrence

new anti-inflammatory compound developed at the University of California, Davis, acts as a “surge protector” to suppress inflammation and reduce cancer growth, at least in mouse models of cancer. The work was published in the Proceedings of the National Academy of Sciences. “We are excited about this research and its potential,” […]

ZIP Code or Genetic Code?

When it comes to disease and health, which is more powerful—ZIP code or genetic code? The degree to which nature and nurture affect disease and health remains one of the eternal—and still unanswerable—questions in medicine. Now a team of investigators from Harvard Medical School and the University of Queensland in Australia […]

Scientists Discover, Deplete New Immune Cell and Halt Runaway Lung Scarring in Mice

Idiopathic pulmonary fibrosis (IPF) is a fatal condition that leaves lung tissue permanently scarred and leads to the decline and eventual failure of the respiratory system. For those diagnosed with the disease, treatment options are limited and the prognosis is poor. But a new study published in the journal Nature Immunology breathes […]

Drug Hobbles Deadly Liver Cancer by Stifling Protein Production

In laboratory experiments, UC San Francisco researchers successfully beat back the growth of aggressive liver cancers using a surprising new approach. Traditionally, targeted cancer therapies aim to disable proteins borne of cancer-driving genes. Instead, the UCSF scientists prevented these proteins, including those that shield tumors from the immune system, from […]

Hindering melanoma metastasis with an FDA-approved drug

For cancer to spread, it needs a hospitable environment in distant organs. This fertile “soil” can provide a home to circulating malignant cells. Recent research has shown that cancer cells from the primary tumor can help ready this soil by sending out small vesicles. These vesicles contain a cocktail of […]

X-ray experiments reveal important mechanism behind parkinsonian disorders

Gene defect in hereditary forms of the neurological disorder results in manganese poisoning inside cells. A new X-ray study has revealed one of the key mechanisms behind certain familial-parkinsonian disorders. The study demonstrates in detail how poisoning with the metal manganese occurs inside a cell, leading to parkinsonian symptoms. It […]

DNA can help predicting if you will live longer or shorter than an average human

Everyone wants to live a long and healthy life. It is a bit of a goal that everyone has or should have. And we do our best – we work out, we get frequent check-ups, we eat healthy, but still, a big secret to longevity is our genes. Now scientists […]

Alzheimer’s researchers find new culprit and potential treatment target for disease

Leaky capillaries in the brain portend early onset of Alzheimer’s disease as they signal cognitive impairment before hallmark toxic proteins appear, new USC research shows. The findings, which appeared in the journal Nature Medicine, could help with earlier diagnosis and suggest new targets for drugs that could slow or prevent the […]

Wild insects ‘get old’ before they die

Short-lived wild insects “get old” – losing some of their physical abilities – before they die, new research shows. Few studies have examined whether insects such as field crickets – whose adult life lasts a few weeks – experience “ageing” in the sense of physical decline in nature. Insects are used […]
