Whole-proteome profiling of human lung cancer brain metastasis-associated fibroblasts


ABSTRACT: Cancer-associated fibroblasts (CAFs) are increasingly recognized as an important component of the brain metastasis tumour microenvironment; however, their proteomic phenotype remains poorly characterized. This dataset contains mass spectrometry-based proteomic profiles of primary human brain metastasis-associated fibroblasts (BrM-CAFs) isolated from lung cancer brain metastases (L-BrM-CAF, n = 3) and control, non-tumorous subgalear fibroblasts (Subgalear-NF, n = 3). Whole-cell lysates were analyzed using data-independent acquisition (DIA) mass spectrometry, supported by a project-specific spectral library generated from data-dependent acquisition (DDA) measurements. The dataset was generated to characterize the molecular phenotype of BrM-CAFs and to investigate protein-level alterations associated with stromal activation, extracellular matrix remodelling, and tumour–stroma interactions. The data provide a resource for studies of the brain metastasis microenvironment and CAF biology.

Brain metastases (BrM) are a frequent and life-threatening complication of solid tumours, with lung cancer representing their most common source. While cancer-associated fibroblasts (CAFs) are well-established contributors to tumour progression in many extracranial malignancies, their presence and function within the brain tumour microenvironment, where fibroblasts have long been considered scarce or absent, remain poorly understood. Here, we isolated and characterised fibroblast-like cells from  ...[more]
