“…Ecad high MBM featured a proliferative and likely drug-naïve and/or drug-responsible phenotype and GSEA suggests that this subgroup but not Ecad low /NGFR high tumors probably depends on oxidative phosphorylation (OXPHOS) as previously delineated 87 . Our hypothesis is strengthened by the uncovering of molecular features of drug-naïve MBM by Rabbie et al 88 and Biermann et al 89 , showing that this set of MBM expressed Ecad-associated genes such as ABCB5 or pigmentation-related factors such as MLANA , PMEL or DCT found in either of the studies (Fig. 9b ).…”

“…Finally, we evaluated the scalability of Smoother-guided data imputation and deconvolution on datasets with higher spatial resolution. Using the Slide-seq2 data of human melanoma brain metastasis 23 , we confirmed that Smoother, benefiting from the modular design and implementation, can enhance spatial patterns and provide accurate cell-type mappings to tens of thousands of locations while maintaining high computational efficiency ( Supplementary Fig. 16 ).…”

“…We preprocessed the Slide-seqV2 data of melanoma brain metastasis (MBM) and extracranial melanoma metastasis (ECM) and the paired scRNA-seq data following the original publication 23 using the R package Seurat 34 . Functional signature scores were calculated by averaging the expression of genes involved in the corresponding pathway.…”

“…For example, melanoma cells have been shown to re-instate neural crest-specific transcription factors that may provide an adaptive, survival advantage in the brain microenvironment 16,3739 . Notably, while one recent study has found that AXL and EMT-like melanoma cells are enriched in melanoma brain metastases, another recent study found that brain metastases were instead enriched in neuronal-lineage genes and melanocytic state markers such as MITF and SOX10 40,41 . Most likely, melanoma phenotypic plasticity produces a spectrum of different lineage states that interact cooperatively to maintain tumor survival, persistence, and invasion as they compete for various niches in the brain microenvironment (i.e., perivascular positioning).…”
