Deep learning inference of miRNA expression from bulk and single-cell mRNA expression

Ripan, R. C.Open in Google Scholar•Athaya, T.Open in Google Scholar•Li, x.Open in Google Scholar•Hu, H.Open in Google Scholar

Understanding the activity of miRNA in individual cells presents a challenge due to the limitations of single-cell technologies in capturing miRNAs. To tackle this obstacle, we introduce two deep learning models: Cross-Modality (CM) and Single-Modality (SM). These models utilize encoder-decoder architectures to predict miRNA expression at the bulk and single-cell levels from mRNA data. We compared CM and SM with a state-of-the-art approach, miRSCAPE, using both bulk and single-cell datasets. We found that both CM and SM outperformed miRSCAPE in terms of accuracy. We also observed that integrating miRNA target information led to a significant enhancement in performance compared to using all genes. These models offer valuable tools for predicting miRNA expression from single-cell mRNA data.

Streamlining Multiplexed Tissue Image Analysis with PIP{Sigma}X: An Integrated Automated Pipeline for Image Processing and EXploration for Diverse Tissue Types
Spatial proteomics via multiplexed tissue imaging is transforming how we study biology, enabling researchers to investigate dozens of markers in a single tissue section and explore how cells behave in their native habitat. While imaging technologies have advanced rapidly, data analyses remain a bottleneck. To address this, we developed PIP{Sigma}X (Pipeline for Image Processing and EXploration), a...

IsoBayes: a Bayesian approach for single-isoform proteomics inference
Studying protein isoforms is an essential step in biomedical research; at present, the main approach for analyzing proteins is via bottom-up mass spectrometry proteomics, which return peptide identifications, that are indirectly used to infer the presence of protein isoforms. However, the detection and quantification processes are noisy; in particular, peptides may be erroneously detected, and mos...

Application of spatial transcriptomics across organoids: a high-resolution spatial whole-transcriptome benchmarking dataset
Stem cell-derived organoid models hold great promise to model tissue-specific disease. To enable this, it is crucial to determine how their composition compares to endogenous organs. However, technologies such as spatial transcriptomics (STs) that can inform on regional molecular identity have been challenging to apply to organoids. Here we present the first systematic profiling of multiple organo...

RNAcompare: Integrating machine learning algorithms to unveil the similarities of phenotypes based on clinical, multi-omics using Rheumatoid Arthritis and Heart Failure as Case Studies
Background: Gene expression analysis is crucial for understanding the biological mechanisms underlying patient subgroup differences. However, most existing studies focus primarily on transcriptomic data while neglecting the integration of clinical heterogeneity. Although batch correction methods are commonly used, challenges remain when integrating data across different tissues, omics layers, and ...

multideconv - an integrative pipeline for combining first and second generation cell type deconvolution results
Summary: The number of computational methods for cell type deconvolution from bulk RNA-seq data has been increasing in the last years, but their high feature complexity and variability of results across methods and signatures limit their utility and effectiveness for patient stratification. Applying multiple combinations of deconvolution methods and signatures often results in hundreds of redundan...

INLAomics for Scalable and Interpretable Spatial Multiomic Data Integration
Integrating spatial transcriptomics with antibody-based proteomics enables the investigation of biological regulation within intact tissue architecture. However, current approaches for spatial multi-omics integration often depend on dimensionality reduction or autoencoders, which disregard spatial context, limit interpretability, and face challenges with scalability. To address these limitations, ...
