SAMHD1 can suppress lung adenocarcinoma progression through the negative regulation of STING.

ABSTRACT:

Background

The sterile alpha motif (SAM) domain and histidine-aspartate (HD) domain-containing protein 1 (SAMHD1) has been specifically linked to lung cancer. However, the underlying mechanisms in regulating lung adenocarcinoma (LAC) are unclear. The aim of this study was to assess the specific regulation between SAMHD1 and LAC.

Methods

We retrospectively reviewed 238 patients who underwent surgery for LAC between January 2018 and December 2019. The expression of SAMHD1 was detected by quantitative reverse-transcription polymerase chain reaction (RT-qPCR) in tumors and paired adjacent tissues. A lentivirus was used to overexpress SAMHD1 and stimulator of interferon genes (STING) in A549 cells; and RT-qPCR and western blot analysis were performed to verify their levels. Cell
