This dataset contains summary data visualizations and clinical data from a comprehensive genomic and transcriptomic analysis of 38 acral lentiginous melanomas (ALM) from 34 patients. The study was conducted to analyze ALM, a rare sun-shielded melanoma subtype of cutaneous melanoma (CM) which is associated with worse survival than other CM in an effort to delineate non-UV oncogenic mechanisms. The...

From the dbGaP study description: "In this study, we performed paired tumor/normal long insert whole genome and exome sequencing and tumor RNA sequencing on primary or metastatic acral melanoma tumors collected from 34 patients. Patients were enrolled from either Vanderbilt University or the Memorial Sloan-Kettering Cancer Center. We report an integrated analysis of DNA and RNA sequencing data to...

From Dryad summary: "Abstract: The classification of melanoma into four histological subtypes has been questioned regarding its clinical validity in providing relevant information for treatment for metastatic tumors. Specific genetic alterations are associated with particular clinical and histopathological features, suggesting that these could be helpful in refining existing melanoma classification...

Summary from GEO: "Cancer cells interact with a wide variety of other cell types, but our understanding of microenvironmental heterogeneity and how it influences tumor phenotypes is limited. While single-cell RNA-seq (scRNA-seq) has helped define these TME cell types, it provides limited information on the mechanisms that define how individual tumor cells interact with TME. Here, we integrate spatial...

Summary from GEO: "Oncogenic alterations to DNA are not transforming in all cellular contexts. This may be due to pre-existing transcriptional programs in the cell of origin. Here, we define anatomic position as a major determinant of why cells respond to specific oncogenes. Cutaneous melanoma arises throughout the body, whereas the acral subtype arises on the palms of the hands, soles of the feet,...
