中国医学科学院肿瘤研究所梁克等历经3年的研究证实：放射线可以诱导肿瘤细胞发生凋亡，凋亡的产生是肿瘤受照射后细胞死亡的主要原因之一。中国医学科学院肿瘤研究所梁克、王凤纬等在沈瑜、殷蔚伯等教授的指导下，采用多种分子生物技术开展了深入研究发现，放射线不仅造成DNA Liang Ke, a researcher at the Institute of Cancer, Chinese Academy of Medical Sciences, has confirmed after three years of research that radiation can induce tumor cells to undergo apoptosis. Apoptosis is one of the major causes of cell death after irradiation. Institute of Tumor Research, Chinese Academy of Medical Sciences, Liang Ke, Wang Fengwei, etc., under the guidance of Professors Shen Yu and Yin Weibo, conducted in-depth research using a variety of molecular biological technologies and found that radiation not only causes DNA damage.
