Summary
We introduce STREAK, a new supervised method for estimating cell surface receptor abundance from single-cell RNA sequencing data. STREAK improves accuracy for cell type identification and understanding cell interactions.
Area of Science:
- Single-cell genomics
- Computational biology
- Biostatistics
Background:
- Accurate cell surface receptor abundance estimation is crucial for single-cell transcriptomics analyses, including cell type classification and cell-cell interaction studies.
- Previous methods like SPECK (Surface Protein abundance Estimation using CKmeans-based clustered thresholding) showed promise but relied solely on scRNA-seq data.
- Challenges remain in precisely quantifying receptor levels, impacting downstream biological interpretations.
Purpose of the Study:
- To develop and evaluate STREAK (gene Set Testing-based Receptor abundance Estimation using Adjusted distances and cKmeans thresholding), a novel supervised method for receptor abundance estimation.
- To compare STREAK's performance against existing unsupervised and supervised methods using diverse datasets.
- To demonstrate STREAK's advantages in biological interpretability and statistical transparency.
Main Methods:
- Developed STREAK, a supervised method utilizing joint scRNA-seq/CITE-seq training data.
- Employed a thresholded gene set scoring mechanism within STREAK for receptor abundance estimation.
- Evaluated STREAK against other methods on six joint scRNA-seq/CITE-seq datasets across human and mouse tissues.
Main Results:
- STREAK demonstrated superior performance compared to unsupervised and other supervised receptor abundance estimation techniques.
- The method showed improved accuracy in estimating cell surface receptor abundance.
- Evaluations across multiple datasets confirmed STREAK's robustness and effectiveness.
Conclusions:
- STREAK represents a significant advancement in estimating cell surface receptor abundance from scRNA-seq data.
- The supervised approach offers enhanced biological interpretability and a more transparent statistical framework.
- STREAK provides a more reliable tool for cell type and interaction analyses in single-cell studies.
