Insights

Noncoding RNAs (ncRNAs) are crucial in gene regulation and cancer. This study reviews existing ncRNA databases, highlighting their limitations for cancer research and the need for a centralized, community-driven data repository.

Area of Science:

  • Genomics
  • Bioinformatics
  • Molecular Biology

Background:

  • Gene expression dysregulation is a hallmark of diseases like cancer.
  • Noncoding RNAs (ncRNAs), including microRNAs, circular RNAs, and small nucleolar RNAs, play vital roles in gene regulation and cellular communication.
  • Existing knowledge on ncRNAs is fragmented across numerous specialized databases.

Purpose of the Study:

  • To review and discuss complementary ncRNA databases.
  • To highlight the relevance of these databases for cancer research.
  • To identify current challenges and limitations in ncRNA data accessibility and integration.

Main Methods:

  • Literature review of existing ncRNA databases.
  • Analysis of database complementarity and coverage.
  • Evaluation of database utility for cancer research applications.
  • RNA-sequencing (RNA-seq) data context.

Main Results:

  • Identified a limited number of highly complementary ncRNA databases.
  • Demonstrated the relevance of these databases for advancing cancer research.
  • Revealed significant problems and limitations in current ncRNA data repositories, including fragmentation and lack of standardization.

Conclusions:

  • A significant need exists for a centralized or shared database for ncRNAs.
  • Future efforts should focus on establishing a unified platform that enforces community reporting and quality standards.
  • Improved data integration and accessibility are critical for comprehensive ncRNA research, particularly in oncology.

Ribosomal RNA Synthesis02:53

Ribosomal RNA Synthesis

Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Nonsense-mediated mRNA Decay02:27

Nonsense-mediated mRNA Decay

The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

Types of RNA01:20

Types of RNA

Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Ribosome Profiling02:24

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

RNA-seq03:21

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...
