新发现的一个与人类黑素瘤细胞分化为非增生状态有关的基因可能是比p53更有效的肿瘤抑制剂。美国哥伦比亚大学内科学与外科学学院(New York,NY)的研究者们已经把这个被叫做mda—7的基因买给了Genquest Inc.(New York, NY),并进行了基因治疗实验,检测它是否可以抑制肿瘤在小鼠体内的生长。由哥伦比亚大学Paul Fisher领导的研究者去年报道,mda—7基因(与黑素瘤分化相关)不 A newly discovered gene that is involved in the differentiation of human melanoma cells to a non-proliferative state may be a more potent tumor suppressor than p53. Researchers at the University of Columbia School of Medicine and Surgery (New York, NY) have purchased the gene, called mda-7, from Genquest Inc. (New York, NY) and conducted gene therapy experiments that detect Whether it can inhibit tumor growth in mice. Researchers led by Paul Fisher at Columbia University reported last year that the mda-7 gene (associated with melanoma differentiation) is not
