ADAR1 enhances tumor proliferation and radioresistance in non-small cell lung cancer by interacting with Rad18.

ABSTRACT:

Purpose

Posttranslational modification significantly contributes to the transcriptional diversity of tumors. Adenosine deaminase acting on RNA 1 (ADAR1) and its mediated adenosine-to-inosine (A-to-I) editing have been reported to influence tumorigenesis across various cancer types. Nevertheless, the relationship between ADAR1 and radioresistence remains to be elucidated.

Methods

The protein expression was detected by immunohistochemistry and Western Blot, while the mRNA expression was measured by RT-qPCR. The tumor growth was evaluated by CCK8, colony formation assays, EdU assay, and in-vivo mouse model. γ-H2AX foci formation, neutral comet tailing assay, and clonogenic cell survival assay were performed to determine the DNA damage and radiosensitivity. RNA-seq was conducted
