hdWGCNA analysis of gene co-expression modules and functional enrichment in Müller glial subpopulations cluster 0 and 1 in STZ and Ctrl groups. (A) Soft power threshold selection for the weighted network construction in the hierarchical clustering analysis of Müller glia subpopulations. The figure showed the correlation between the soft power threshold and model fit, as well as mean connectivity, median connectivity and max connectivity, with the optimal threshold indicated for constructing the network. The selected power (β = 5) represents the minimal value satisfying the scale-free topology criterion while preserving sufficient network connectivity for module detection. (B) Hierarchical clustering dendrogram of Müller glial subpopulations based on gene expression profiles. The tree showed clustering of the different gene modules identified in the analysis, with modules labeled Müller-M1 to Müller-M6. Each module represents a set of co-expressed genes associated with specific biological functions in Müller glial subpopulation. (C) Module feature plots showing the expression patterns of each module (M1-M6) within Müller cell subpopulations. For each module, cells were colored by module expression level (low to high), illustrating the distribution of module activity across Müller cell subpopulations. (D) The module membership (kME) for all genes was calculated, and the top-ranked 10 genes within each module were visualized using PlotKMEs. (E) Dot plots respectively showing the expression of distinct gene co-expression modules in Müller glial cell subpopulation and the module expression within subpopulations under different conditions. (F) Co-expression network comprising the top five hub genes from each co-expression module.
