Revealing Tissue Heterogeneity and Spatial Dark Genes from Spatially Resolved Transcriptomics by Multiview Graph Networks

Ying Li,
Yuejing Lu,
Chen Kang
et al.

Abstract: Spatially resolved transcriptomics (SRT) is capable of comprehensively characterizing gene expression patterns and providing an unbiased image of spatial composition. To fully understand the organizational complexity and tumor immune escape mechanism, we propose stMGATF, a multiview graph attention fusion model that integrates gene expression, histological images, spatial location, and gene association. To better extract information, stMGATF exploits SimCLRv2 for visual feature exaction and employs edge featur… Show more

“…The detection of critical signals for abrupt deterioration is pivotal in the majority of complex diseases. However, the application of existing critical-state detection methods to bulk RNA-sequencing data with limited sample sizes or single-cell data is constrained by the substantial noise inherent in the data [ 36 ]. In this research, we present a robust computational method at the specific sample level, called SCNE, that is capable of constructing a sample-specific causality network for each individual and efficiently identifying critical points or pre-deterioration states associated with disease deterioration.…”
