Background:
- Eukaryotic regulatory small RNAs (sRNAs) are crucial for cellular functions and serve as valuable biomarkers.
- sRNA biomarkers offer advantages over mRNA biomarkers, including higher accuracy and earlier disease detection.
- Understanding sRNA expression is key for advancing biological insights and disease management.
Purpose of the Study:
- To discuss considerations for small RNA (sRNA)-based high-throughput sequencing (HTS) profiling.
- To focus on sources of systematic error in sRNA expression profiling methods.
- To aid researchers in designing and interpreting HTS-based sRNA profiling experiments.
Main Methods:

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.

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.
