最近证明,人体内一种物质如发生异常,则能导致癌瘤。这种物质是血小板生长因子(PDGF)。PDGF与癌的关系是由伦敦(癌瘤研究基金实验室)的Michael Waterfield和美国加利福尼亚的Russell Doolittle各自独立研究,但不约而同地发现的(《Nature》第304卷,第55页),他们在最近举行的美国生物化学学会上宣布了此一发现。 PDGF实际上与一小簇基因的产物相同,而该簇基因则与癌瘤有关(《New Scientist》
It has recently been demonstrated that abnormalities in a substance in the human body can cause cancer. This substance is platelet growth factor (PDGF). The relationship between PDGF and cancer was independently studied by Michael Waterfield (Canadian Cancer Research Fund Laboratories) in London and Russell Doolittle in California, USA, but they were found invariably (Nature, Vol. 304, p. 55). The discovery was announced by the American Society of Biochemistry. PDGF is actually the same product as a small cluster of genes that are associated with cancer (New Scientist)
