| Artificial cells to study molecular crowding and gene expression created Posted: 14 Jul 2013 01:09 PM PDT Scientists have approximated molecular crowding in an artificial cellular system and found that tight quarters help the process of gene expression, especially when other conditions are less than ideal.  |
| Antiviral enzyme contributes to several forms of cancer Posted: 14 Jul 2013 01:09 PM PDT Researchers have discovered that a human antiviral enzyme causes DNA mutations that lead to several forms of cancer.  |
| Undiagnosed pre-diabetes highly prevalent in early Alzheimer's disease study Posted: 14 Jul 2013 01:08 PM PDT When a neurologist began enrolling people with mild to moderate Alzheimer's disease into a nationwide study last year, he expected to find only a handful of participants with undiagnosed glucose intolerance, as all the patients were already under a doctor's care and those with known diabetes were excluded. But the scientists said he was "shocked" by how many study participants were found to have pre-diabetes -- a finding that is triggering important questions.  |
| Kill-switch controls immune-suppressing cells, scientists discover Posted: 14 Jul 2013 01:06 PM PDT Scientists have uncovered the mechanism that controls whether cells that are able to suppress immune responses live or die.  |
| DNA flaws may contribute to cancer risk in people with type 2 diabetes Posted: 14 Jul 2013 01:06 PM PDT A type of genetic abnormality linked to cancer is more common in people with type 2 diabetes than the rest of the population, a new study has found.  |
| Key step in molecular 'dance' that duplicates DNA deciphered Posted: 14 Jul 2013 01:05 PM PDT Scientists have captured new details of the biochemical interactions necessary for cell division. The research may suggest ways for stopping cell division when it goes awry.  |
| Drug candidate leads to improved endurance Posted: 14 Jul 2013 01:05 PM PDT Scientists have shown that a drug candidate significantly increases exercise endurance in animal models.  |
| Proteins involved in immunity potentially cause cancer Posted: 14 Jul 2013 01:05 PM PDT A set of proteins involved in the body's natural defenses produces a large number of mutations in human DNA, according to a new study. The findings suggest that these naturally produced mutations are just as powerful as known cancer-causing agents in producing tumors.  |
| Strong pregnancy outcomes for survivors of childhood cancer Posted: 13 Jul 2013 06:51 AM PDT New research finds that almost two-thirds of female survivors of childhood cancer who tried unsuccessfully for at least a year to conceive eventually got pregnant.  |
| New theory uncovers cancer's deep evolutionary roots Posted: 12 Jul 2013 07:28 AM PDT A new way to look at cancer -- by tracing its deep evolutionary roots to the dawn of multicellularity more than a billion years ago -- has been proposed. If their theory is correct, it promises to transform the approach to cancer therapy, and to link the origin of cancer to the origin of life and the developmental processes of embryos.  |
