The cancer-testis lncRNA LINC01940 promotes gastric cancer malignant progression and chemoresistance by enhancing ribosome biogenesis via TAF15-mediated NOL11 SUMOylation.

ABSTRACT:

Background

Aberrant ribosome biogenesis promotes gastric cancer (GC) progression and contributes to chemoresistance by sustaining protein synthesis, upon which GC cell survival depends. However, the regulatory role of cancer-testis-associated long noncoding RNAs (CT-lncRNAs) in modulating ribosome biogenesis in GC remains largely unexplored.

Methods

First, we performed a screening of lncRNAs and identified CT-lncRNA LINC01940 on the basis of integrated expression and survival analyses using The Cancer Genome Atlas (TCGA) data. Subsequently, the impact of LINC01940 on GC progression and chemosensitivity was evaluated using in vitro cell functional assays, patient-derived organoid models, and in vivo subcutaneous tumor xenograft experiments. To further elucidate the underlying
