How does single-cell RNA sequencing help identify potential biomarkers for age-related diseases?
Best insight from top research papers
Single-cell RNA sequencing (scRNA-seq) helps identify potential biomarkers for age-related diseases by providing a comprehensive understanding of cellular events at the single-cell level. It allows for the profiling of gene expression in individual cells, enabling the identification of specific genes or gene signatures associated with age-related diseases. For example, scRNA-seq analysis of retinal lesions in age-related macular degeneration (AMD) identified activated glial populations enriched in the early phase of the disease . In another study, scRNA-seq analysis of immune cells revealed age-associated alterations in regulatory factors controlling antigen processing, inflammation, collagen processing, and circadian rhythm, which are implicated in age-related diseases . Additionally, scRNA-seq combined with other techniques, such as single-cell ATAC sequencing, can provide a comprehensive characterization of aging-related genes across diverse tissue-cell types, facilitating anti-aging and aging-related disease research .

How to detect the biomarker in Single cell?5 answersSingle-cell biomarker detection can be achieved using various methods. One approach is to perform trajectory inference to identify the lineage of transitional processes in the epithelial-mesenchymal transition (EMT) progression. Another method involves using Fluorescent-quenching Aptamer-based Single-cell Western Blotting (FAS-WB) for multiplex protein detection at single-cell resolution. Additionally, sc2marker, a computational approach based on the maximum margin index and a database of proteins with antibodies, can be used to select markers for flow cytometry or imaging. Furthermore, spatially resolved biomarker detection on single cells can be achieved using multiplex imaging, as demonstrated in the TRACERx study. These methods offer efficient ways to detect biomarkers in single cells, providing valuable insights into cellular processes and disease progression.

What is Single cell RNA-Seq Sequencing technology?3 answersSingle-cell RNA sequencing (scRNA-seq) is a technique used to analyze gene expression at the single-cell level. It provides high-resolution transcriptome data, allowing researchers to understand the heterogeneity of cell populations. scRNA-seq can be performed using different sequencing technologies, such as short-read sequencing and long-read sequencing. Short-read sequencing is commonly used and is effective for characterizing cell types, states, and dynamics. However, it is limited in its ability to comprehensively characterize RNA isoforms. On the other hand, long-read sequencing enables the detection of RNA isoforms but has lower throughput and can sequence artifacts. To overcome these limitations, researchers have developed hybridization capture methods, such as Single-cell Targeted Isoform Long-Read Sequencing (scTaILoR-seq), which improve the detection of RNA isoforms and allow for exploration of transcriptional variation at single-cell resolution. Another method, called scFAST-seq, combines semi-random primers with high reverse transcription efficiency and template switching to construct full-length RNA libraries. It has advantages in detecting non-polyadenylated transcripts, covering longer transcript length, and identifying more splice junctions. Overall, scRNA-seq is a powerful tool that has revolutionized our understanding of gene expression and cellular heterogeneity at the single-cell level.
