HOXD12 and oligodendroglioma: To determine HOXD12 activity in specific cell compartments and associated cell states, we analyzed high-quality paired oligodendroglioma single-nucleus ATAC sequencing (snATAC-seq) and single-nucleus RNA sequencing (snRNA-seq) data published by Blanco-Carmona et al. (N = 7729) and snATAC-seq data published by Wang et al. (N = 10,281), from which we estimated snRNA-seq reads using Signac’s GeneActivity function [10, 73, 82].
