Ribosome Profiling02:24

Ribosome Profiling

3.9K
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 Nucleolus02:55

The Nucleolus

9.8K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Ribosomal RNA Synthesis02:53

Ribosomal RNA Synthesis

14.1K
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,...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Rheumatology

Background:

  • Osteoarthritis (OA) involves changes in articular chondrocyte phenotype, but the origins are unclear.
  • Small nucleolar RNAs (snoRNAs) regulate RNA modifications, impacting spliceosome and ribosome function.
  • Altered protein synthesis needs in OA may involve snoRNA-mediated fine-tuning.

Purpose of the Study:

  • To investigate the role of small nucleolar RNAs (snoRNAs) in osteoarthritis (OA).
  • To develop and describe methods for isolating and quantifying snoRNAs in cartilage.

Main Methods:

  • Targeted isolation of specific snoRNAs from whole cartilage.
  • Global analysis of snoRNA expression profiles in cartilage.
  • Quantitative methods for accurate measurement of snoRNA levels.

Main Results:

  • Established protocols for effective snoRNA isolation from cartilage.
  • Demonstrated feasibility of both targeted and global snoRNA quantification.
  • Provided a foundation for future studies on snoRNA function in OA.

Conclusions:

  • The described methods enable comprehensive analysis of snoRNAs in OA cartilage.
  • Understanding snoRNA roles could reveal new therapeutic targets for osteoarthritis.
  • Further research is warranted to elucidate the precise functions of snoRNAs in OA pathogenesis.
