Mutations of a gene active in both parts of the body could help explain some diseases
want to talk about women’s periods. The reluctance to speak plainly about “that time of the month” might explain why some gynaecological conditions are often undiagnosed. Take
, a chronic disease that causes period pain and excessive bleeding. The condition is common and debilitating: around 10% of women of reproductive age have it. Many wait ten years for a diagnosis.One study in Australia found that, on average, patients with endometriosis used 60% of their statutory sick leave to cope with the symptoms. Yet funding for research is surprisingly low, given the disease’s heavy toll.
Scientists have little understanding of what causes endometriosis and how to cure it. Doctors have noted that patients with the condition tend to suffer from other ailments, including migraines and mental disorders, but these links are still poorly understood. Scientists had long assumed that women with endometriosis were depressed because they suffered from chronic pain.
To probe this the authors looked at genetic variations in more than 200,000 women, 8,000 of whom had been diagnosed with endometriosis. They found that some gene variants were more likely to be present in patients suffering from both endometriosis and a mental disorder, such as anxiety or depression. One specific variant affects a gene called

Scientists harness 'helper' T cells to treat tumorsScientists are on the hunt for a unique set of mutations, called 'neoantigens,' that let the immune system distinguish tumor cells from normal cells. Their goal is to help the immune system react to neoantigens and target tumor cells for destruction.
