Insights

A new method, MIRA, analyzes cancer mutations in noncoding RNA regions. It identifies how mutations in RNA-binding protein motifs impact RNA processing, offering insights into cancer genome variants.

Area of Science:

  • Genomics
  • Cancer Research
  • RNA Biology

Background:

  • Determining the significance of somatic mutations in noncoding cancer regions is challenging.
  • Previous studies focused on individual regulatory sites, not combinatorial effects on RNA motifs.
  • The role of mutations in common RNA regulatory motifs in cancer remains underexplored.

Purpose of the Study:

  • To develop a method for unbiased, comprehensive study of significantly mutated regions affecting RNA-binding protein (RBP) binding sites in cancer.
  • To investigate the combinatorial contribution of mutations to common RNA regulatory motifs.
  • To identify alterations in RNA expression and splicing linked to mutations on RBP binding sites.

Main Methods:

  • Developed MIRA (mutation identification for RNA alterations) for analyzing noncoding mutations.
  • Utilized RNA sequencing (RNA-seq) data alongside mutation data.
  • Identified significantly mutated regions (SMRs) impacting RBP binding sites.

Main Results:

  • Identified SRSF10, MBNL1, and HNRPLL motifs in introns and UTRs with specific mutational patterns.
  • Found mutations disrupting motifs and impacting RNA processing, including splicing.
  • Linked mutations in RBP binding sites to altered RNA expression and splicing.

Conclusions:

  • MIRA facilitates integrative analysis of multiple genome sites acting through common RBPs.
  • The study aids in interpreting noncoding variants in cancer genomes.
  • Identified novel alterations in introns, UTRs, and long noncoding RNAs affecting RNA processing.

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
