Summary from GEO: " Expression data from dendritic cell subsets derived or sorted from control littermate and CD11c-Cre/BRAFV600E(flox-CA) mice Langerhans cell histiocytosis (LCH) is an inflammatory myeloid neoplasia characterized by granulomatous lesions containing pathological CD207+ dendritic cells (DCs) with constitutively activated mitogen-activated protein kinase (MAPK) pathway signaling. Approximately...

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: "Mutations activating the KRAS GTPase or the BRAF kinase are frequent in colorectal cancer and are thought to constitutively activate the terminal mitogen-activated protein kinase, ERK. Using mass cytometry, we found graded phosphorylation of ERK anti-correlated with cell differentiation in patient-derived colorectal cancer organoids, and unexpectedly this gradient was observed...

Summary from GEO: "Goals of the study was to compare transcripional and phenotypic response of mouse intestinal organoid cultures to the KRAS(G12V) or BRAF(V600E)oncogenes." Overall design from GEO: "Two biological replicates of organoids with transgenic luc-tdTomato, KRAS(G12V)-tdTomato, BRAF(V600E)-tdTomato were analysed by RNA-Seq. By comparing 7-10 x 10E7 50bp paired end reads per library...

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,...

Description from dbGaP: "Desmoplastic melanoma is an infrequent variant of melanoma with sarcomatous histology, distinct clinical behavior, and unknown pathogenesis. We performed low-coverage genome and high-coverage exome sequencing of 20 desmoplastic melanomas, followed by targeted sequencing of 293 genes to validate candidate genes. A high mutation burden (median 62 mutations/Mb) ranked desmoplastic...
