MetabolomicsTargeted metabolomics of pancancer brain metastasis

The molecular heterogeneity of brain metastases hampers therapeutic development for cures. To address this unmet and urgent need, we constructed a comprehensive multi-omic, single cell, and spatially resolved atlas of 1,032 pan-cancer brain metastases, identifying four robust molecular subtypes ...

MetabolomicsLipid Profiles of Human Brain Tumors Obtained by High-Resolution Negative Mode Ambient Mass Spectrometry

Alterations in cell metabolism, including changes in lipid composition occurring during malignancy, are well characterized for various tumor types. However, a significant part of studies that deal with brain tumors have been performed using cell cultures and animal models. Here, we present a data...

TranscriptomicsTranscription profiling of human breast cancer brain metastases in a mouse xenograft model with vehicle of vorinostat treatment
Gene Expression Profiling of a Mouse Xenograft Model of â??Triple-Negativeâ?? Breast Cancer Brain Metastases With and Without Vorinostat Treatment. Purpose: As chemotherapy and molecular therapy improve the systemic survival of breast cancer patients, the incidence of brain metastases increases. Few...

ProteomicsThe murine metastatic microenvironment of experimental brain metastases in breast cancer differs by host age in vivo: A proteomic study.
Breast cancer in young patients is known to exhibit more aggressive biological behavior and is associated with a less favorable prognosis than the same disease in older patients, owing in part to an increased incidence of brain metastases, the mechanistic explanations behind which remain poorly unde...

TranscriptomicsAnalyses of Human Brain Metastases of Breast Cancer Reveal the Association between HK2 Up-Regulation and Poor Prognosis
Analyses of Resected Human Brain Metastases of Breast Cancer Reveal the Association between Up-Regulation of Hexokinase 2 and Poor Prognosis. Brain metastases of breast cancer seem to be increasing in incidence as systemic therapy improves. Metastatic disease in the brain is associated with high mor...

TranscriptomicsGene expression profiling of melanoma brain metastases and matched extracranial metastases
An improved understanding of the molecular pathogenesis of brain metastases, one of the most common and devastating complications of advanced melanoma, may identify and prioritize rational therapeutic approaches for this disease. In particular, the identification of molecular differences between bra...

MetabolomicsMetabolic differences between primary and brain metastatic breast tumors revealed by in vivo [U-¹³C]-glucose infusion in mice

Metastatic breast tumors must adapt to the metabolic constraints of their target tissues. To understand how tumor metabolism varies across sites, we compared glucose utilization in primary mammary fat pad (MFP) tumors and brain metastases derived from the breast cancer cell line MDA-MB-231. Tumor...

TranscriptomicsIdentification of novel metastases-suppressor genes involved in lung cancer brain metastases formation.
Initial screening for potential metastases suppressors down regulated by methylation was performed using lung cancer cell line models specific for site-specific metastasation. Gene expression profiling and qRT-PCR validations were conducted on tumor tissues from primary lung cancer (LC) and brain me...

GenomicsMolecular Profiling Reveals Unique Immune and Metabolic Features of Melanoma Brain Metastases
There is a critical need to improve our understanding of the pathogenesis of -melanoma brain metastases (MBM). Thus, we performed RNA sequencing on 88 resected MBMs and 42 patient-matched extracranial metastases; tumors with sufficient tissue also underwent whole-exome sequencing, T-cell receptor se...
