Immune Processes Linked to Multiple Sclerosis Genetics

Multiple sclerosis (MS) is an autoimmune inflammatory degenerative disease of the central nervous system that often starts in young adulthood and affects 2.3 million individuals worldwide. While prior genetic studies have implicated the adaptive immune system in the disease, in particular T cells, much of the genetic architecture of MS has remained unknown. More...

Methylation Signature Identified for Brain Metastases of Lung Cancer

When lung cancer metastasizes to the brain, it means the primary lung cancer has created a secondary cancer in the brain. About 20% to 40% of adults with non-small cell lung cancer go on to develop brain metastases at some point during their illness. More...

PCR Kit Developed for Detection of Q-fever Pathogen

Coxiella burnetii is an obligate intracellular bacterium that causes Q fever in animals and humans. The infection results from inhalation of a spore-like small-cell variant, and from contact with the milk, urine, feces, vaginal mucus or semen of infected animals. More...

Triple-Negative Breast Cancer Classified from Whole-Genome Sequencing

A diagnosis of triple negative breast cancer means that the three most common types of receptors known to fuel most breast cancer growth–estrogen, progesterone and the HER-2/neu gene are not present in the cancer tumor. More...

Multigene Testing for Breast Cancer Patients Proves Cost-Effective

Health systems in the UK and USA could cost-effectively screen all women with breast cancer for risky germline changes in a handful of breast or ovarian cancer genes, according to a new economic modeling analysis, identifying at-risk individuals who could benefit from additional imaging tests and cancer-reducing interventions.

Image: A new blood test has been developed capable of detecting multiple cancer types. The new test looks for DNA, which cancer cells shed into the bloodstream when they die (Photo courtesy of weeksnews).

New Blood Test Capable of Detecting Multiple Cancer Types

A new blood test in development has shown ability to screen for numerous types of cancer with a high degree of accuracy, a trial of the test shows. In study, test proved able to detect and localize more than 20 types of cancer with a high degree of accuracy. More...

Image: In acute myeloid leukemia (AML), defective blood cells (stained purple) are present. When the cells have a double mutation of both the IDH2 and SRSF2 genes (bottom right), the number of defective cells rises considerably, indicating a more lethal disease (Photo courtesy of Cold Spring Harbor Laboratory).

Two Different Mutations Identified as Cause of AML

Two very different mutations have been identified as unexpected partners in crime for causing the blood cancer acute myeloid leukemia (AML). Expert analysis helped reveal how this deadly duo is far more common in AML than thought. More...
