Higgins had been using ovalbumin as his antigen protein in his research. In their unconnected work, the Hammersmith cancer researchers also had been using ovalbumin as a marker on melanoma cells, which cause a type of skin cancer...
...joint study sought to discover whether systems primed by Higgins’ modified E. coli to wipe out invaders bearing ovalbumin would effectively protect mice from the melanoma strain tagged with that protein...
CHECK YOUR MATH The numbers looked good. Too good, it turns out. Early statistics showed cases of melanoma, breast, lung and colorectal cancers to be falling, but researchers now say these numbers are actually up, not down. The source of the error: not all cases diagnosed in a given year were included in that year's tally; between 3% and 12% of cancers went unrecorded because of reporting delays...
...well. That's because the specialized T cells that go after tumors aren't all that numerous or hardy. But a new technique announced in Science last week may overcome both problems. Researchers at the National Cancer Institute took T cells and tumor cells from 13 patients with advanced melanoma, an especially aggressive cancer, and sensitized the Tcells to recognize and attack the tumor cells. Then they cultured the Tcells to multiply their number and injected them back into the patients along with a T-cell growth stimulator. But first the researchers suppressed the cancer patients' immune systems, giving...
...pause and wonder what forces are at work. This was one of those times for me. Maureen was so committed to defeating the scourge of Alzheimer's, to getting more funding for research and increasing understanding of the disease that she sometimes delayed her own treatment for the melanoma that eventually killed...
