老鼠的腫瘤細胞可從周圍健康組織得到粒線體 DNA。也就是說遺傳物質可以水平轉移! During their study, the team observed that DNA from a mouses second genome, or mitochondrial DNA, could be transferred from healthy tissue to tumor cells in mice, promoting cancer growth and spread. After extensive molecular and protein analyses, they eventually established that the DNA had been obtained from non-tumor cells. Furthermore, DNA sequence analysis revealed that the transferred DNA was distinct from that of the original tumor, but identical to surrounding healthy tissue.
