DNA Microarrays

Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

We developed st-Xprop, a new method for spatial transcriptomics analysis. It integrates gene expression and tissue images to accurately identify spatial domains, improving biological insights.

Area of Science:

  • Computational Biology
  • Genomics
  • Bioinformatics

Background:

  • Spatial transcriptomics offers in situ tissue analysis by combining gene expression and spatial coordinates.
  • Integrating gene expression and histology data is challenging due to differing statistical and structural properties.

Purpose of the Study:

  • To propose st-Xprop, a novel cross-propagative graph network for robust spatial domain identification.
  • To effectively integrate heterogeneous spatial transcriptomics data (gene expression and histology).

Main Methods:

  • Constructing modality-specific graphs for gene expression and histological features.
  • Employing alternating cross-modal propagation to model inter-modal heterogeneity.
  • Utilizing dual-graph embedding coupling for unified, low-dimensional representation learning.
