Intratumoral desmoplastic stroma in carcinoma brain metastases harbors stromal cells with a cancer-associated fibroblast (CAF)-like immunophenotype

Abstract Background Research on the tumor microenvironment of brain metastases (BM) has largely focused on immune response, while the intratumoral stromal compartment remains poorly characterized. In primary carcinomas, cancer-associated fibroblast (CAF) are intratumoral stromal...

DNA methylation of silencer-annotated regions at the MGMT locus in the context of promoter and enhancer methylation in glioblastoma and melanoma brain metastases

Abstract Background MGMT promoter methylation is a well-established biomarker in glioblastoma, its relevance in melanoma brain metastases remains controversial. Recent studies indicate that methylation of MGMT enhancers contributes to MGMT regulation, whereas the role of silencer...
