...Sure enough, they found one. Dr. John Mendelsohn, then at the University of California, San Diego, and now president of the M.D. Anderson Cancer Center in Houston, had been focusing since 1981 on a receptor called EGFR, which is host to a protein called epidermal growth factor (EGF). It's a close cousin to HER2, and Mendelsohn and his team know that it is present in a huge variety of tumors; two-thirds of all cancer types, in fact, are blanketed with EGF receptors. In 1984 Mendelsohn and his team showed in mice that blocking the EGF receptor with...
...drug out of that decoy would prove tricky, since the receptor, like HER2, also shows up on noncancerous cells. Researchers are now learning, however, that normal cells are more adept than cancer cells at finding other growth factors on which to rely when EGFR is blocked. But when Mendelsohn applied for his first grant from the National Cancer Institute in 1983, he was rejected. "Nobody thought it would work," he says. The following year he turned to philanthropic sources for research dollars. Last year he wowed colleagues with a compound called IMC-C225, which proved effective in treating colon tumors...
...goal is to detect precisely which molecular processes have gone wrong in an individual patient's cancer. Rather than being identified as lung cancer or breast cancer or kidney cancer, tumors will be tagged as EGFR positive, for example, or COX-2 positive. "The dream," says M.D. Anderson's Mendelsohn, "is that if Mrs. Smith gets a breast biopsy, we'll be able to say, 'Here are the four genes that are abnormal in her tumor,' pull open a drawer, pick out the antibodies or small molecules designed against the abnormal products of those genes, and give her a cocktail...
