Normal tissue adjacent to tumor expression profile ...

tissues adjacent to tumor (PNTAT) are often used as a normal control for cancer research because of the shortage of healthy samples. However, whether PNTAT is truly “normal” is con-troversial. Recent studies have shown that the transcriptomic profiles of PNTAT are distinct from those of healthy and tumor tissues.9 The interaction between ...
