Fibroblast-driven transcriptional reprogramming in response to doxorubicin in heterotypic melanoma spheroids

GSE336658 Mus musculus Expression profiling by high throughput sequencing 8 samples 2026/06/30 GPL24247
Summary
Bulk RNA-sequencing was used to compare the transcriptional response to doxorubicin (DOX) between two multicellular melanoma spheroid models: a baseline model composed of B16.F10 melanoma cells, 2H11 endothelial cells, and bone marrow-derived macrophages (BEM), and a fibroblast-containing counterpart (BEMF) additionally incorporating primary murine dermal fibroblasts. Spheroids of each model were exposed for 48 h to their respective IC30 concentration of doxorubicin (0.56 microM for BEM; 0.79 microM for BEMF) or left untreated as controls, in two independent biological replicates per model/treatment combination. RNA-seq was performed to identify differentially expressed genes associated with fibroblast-dependent modulation of the doxorubicin response in melanoma spheroids.
