Abstract:
Emerging evidence has revealed significant roles for small nucleolar RNAs (snoRNAs) in tumorigenesis. However, the genetic and pharmacogenomic landscape of snoRNAs has not been characterized. Using the genotype and snoRNA expression data from The Cancer Genome Atlas, we characterized the effects of genetic variants on snoRNAs across 29 cancer types and further linked related alleles with patient survival as well as genome-wide association study risk loci. Furthermore, we characterized the impact of snoRNA expression on drug response in patients to facilitate the clinical utility of snoRNAs in cancer. We also developed a user-friendly data resource, GPSno (http://hanlab.uth.edu/GPSno), with multiple modules for researchers to visualize, browse, and download multi-dimensional data. Our study provides a comprehensive genetic and pharmacogenomic landscape of snoRNAs, which will shed light on future clinical considerations for the development of snoRNA-based targeted therapies.
Insights
Small nucleolar RNAs (snoRNAs) play roles in cancer, but their genetic and drug response patterns were unknown. This study maps snoRNA genetics and their impact on cancer drug responses, aiding targeted therapy development.
Area of Science:
- Genomics
- Molecular Biology
- Cancer Research
Background:
- Small nucleolar RNAs (snoRNAs) are increasingly recognized for their involvement in tumorigenesis.
- A comprehensive understanding of the genetic and pharmacogenomic landscape of snoRNAs is lacking.
