11-01-10 Scientists have identified the type of cell that is at the origin of brain tumors known as oligodendrogliomas(少突神经胶质瘤) , which are a type of glioma a category that defines the most common type of malignant brain tumor. In a paper published...
10-12-24 The cell signaling pathway known as Wnt, commonly activated in cancers, causes internal membranes(内膜) within a healthy cell to imprison(监禁,关押) an enzyme that is vital in degrading proteins, preventing the enzyme from doing its job and aff...
10-12-23 Overexpression or hyperactivation of ErbB cell-surface receptors drives the growth of many breast cancers. Drugs, like Herceptin, that block the receptors' signals halt tumor progression in some patients. However, not all patients' tumors respond, w...
10-12-09 Using stem cell technology, reproductive(生殖的) scientists in Texas, led by Dr. Richard R. Berhringer at the M.D. Anderson Cancer Center, have produced male and female mice from two fathers. The study was posted today (Wednesday, December 8) at t...
10-12-06 Sugar molecules coat every cell in our bodies and play critical roles in development and disease, yet the components of these glycans(聚糖,多糖) have been difficult for scientists to study, because of their complexity. Researchers at Emory Univer...
10-11-22 As debilitating(衰弱的) as disease can be, sometimes it acts as a teacher. Researchers at Harvard Medical School and the Harvard School of Dental Medicine have found that by mimicking a rare genetic disorder in a dish, they can rewind the internal...
10-11-16 If researchers could determine how to send signals to cells responding to a spinal cord injury, they might be able to stop one type of cell from doing additional damage at the injury site and instead, coax(哄骗) it into helping nerve cells grow. T...
10-11-08 In an important breakthrough, scientists at McMaster University have discovered how to make human blood from adult human skin. The discovery, published in the prestigious(有名望的) science journal Nature today, could mean that in the foreseeable(...
10-10-06 Evidence reported in the October issue of Cell Metabolism(新陈代谢) , a Cell Press publication, offers a completely new explanation for why people with diabetes account for more than half of all patients requiring dialysis(透析) or kidney transp...
10-09-27 Researchers at Stanford University were able to use light to induce(诱导,引诱) normal patterns of muscle contraction, in a study involving bioengineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins. The new appr...
