The role of adaptive mRNA structures in regulating gene expression in mammalian cells remains poorly understood. Synonymous mutations have been linked to a range of diseases, including cancer, yet their impact on cell biology remains largely unexplored. This opinion focuses on how cancer-associated synonymous mutations...
Oncogenes and tumor-suppressor genes play opposing roles in cancer biology to promote and restrict growth, respectively. Codon usage patterns interface with tRNA modifications to control translation, leading to gene-specific codon signatures with regulatory potential. As such, codon-biased translational regulation has...

Dynamic ribosome heterogeneity has emerged as a potential layer of translational regulation, but whether variation in ribosomal RNA (rRNA) modification stoichiometry can selectively control the translation of mRNAs with shared encoded features remains unclear. Here we show that SNORA81-guided pseudouridylation at U4636...

BACKGROUND
Oral squamous cell carcinoma (OSCC) is represented as a major global health concern with few treatment options. Codon usage bias (CUB) is a non-random selection of synonymous codons. It offers information on gene expression patterns and molecular evolution.
METHODS
This study examined CUB patterns in 1328...

The 5' mRNA leader regulates translation through its length and upstream open reading frames (uORFs), but its systematic remodeling in cancer remains unclear. We analyzed isoform-weighted 5' leader features across The Cancer Genome Atlas, the Genotype-Tissue Expression transcriptomes and the Clinical Proteomic Tumor An...

KRAS mutations occur in over 90% of pancreatic ductal adenocarcinomas (PDACs). Despite recent advances in targeting oncogenic KRAS, tumors eventually acquire resistance. A more comprehensive understanding of the mechanisms connecting KRAS signaling to tumor progression could facilitate the development of effective ther...
