Viral DNA sequence a possible trigger for breast cancer

...ransforms them. This study puts the spotlight on a potential new mechanism for virus-induced breast cell transformation, which has largely been attributed to the integration of viral DNA into locations that trigger the expression of host cancer-causing genes. An intriguing wrinkle to this study is the previous...

Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

...ason why infants with low birth weight have a high potential of developing type 2 diabetes later in life. In studies of mice, the researchers found that poor prenatal nutrition impairs the pancreas's ability to later secrete enough insulin in response to blood glucose. "The bottom line is that if you don't ha...

Neuronal 'traffic jam' marks early Alzheimer's disease
