tRNA m1A modification enhances anti-tumor immunity in macrophages by promoting translation of key interferon associated genes [BMDMs bulk RNA-seq]
Listed in NCBI GEO
The involvement of tRNA m1A modification in the anti-tumoral tumor-associated macrophages (TAMs) has been validated in our study that macrophage-specific knockout of m1A “writer” enzymes TRMT61A leads to increased infiltration of TAMs, impaired CD8+ T cell function, and enhanced tumor growth.
Description
Since TRMT61A-derived tRNA m1A modification mainly enhances translation efficiency, we reasoned that the loss of TRMT61A in macrophages would result in the downregulation of a group of protein levels without affecting their mRNA levels.
To assess the impact of TRMT61A deficiency on mRNA transcript levels in macrophages, we collected TRMT61A-KO and WT BMDMs derived from Trmt61af/fLysmCre and Trmt61af/f mice to perform bulk RNA sequencing. Of total 22173 genes, the mRNA expression of 22054 genes remain unchanged in macrophages upon TRMT61A deletion, suggesting that TRMT61A did not contribute to mRNA transcriptional regulation in macrophages.
