Cancer cells restrict immunogenicity of retrotransposon expression via distinct mechanisms
Overexpression of transposable elements is a common feature of cancer. Sun, You, et al. show that, in pancreatic ductal adenocarcinoma, tumor cells adapt through different mechanisms to mitigate a specific group of dsRNA-producing repeats in a TP53-dependent manner. Their work provides insight into how cancer cells escape the innate immune pressure elicited by repeat expression.
