MetabolomicsTargeting arginine metabolism reverses bone immunosuppressive microenvironment and metastasis in ARID1A-deficient triple negative breast cancer

Bone metastasis is a lethal consequence of breast cancer. AT-rich interaction domain 1A gene (ARID1A), a subunit of the switch/sucrose non-fermentable (SWI/SNF) complex, regulates immunosuppressive tumor microenvironment. ARID1A deficient triple negative breast cancer promotes bone metastasis.To ...

MetabolomicsGut Microbiota Dysbiosis and Hypercholesterolemia Are Associated with Bone Metastasis in Non-Small Cell Lung Cancer
We collected baseline fecal samples from 85 patients with newly diagnosed lung cancer, 51 patients with bone metastasis (M group), and 34 patients without bone metastasis (N group). We conducted metagenomic and metabolomic sequencing to compare the differences in gut microbiota and metabolites betwe...

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 ...

TranscriptomicsABCC5 supports osteoclast formation and promotes breast cancer metastasis to bone
Bone is the primary site of breast cancer metastasis and complications associated with bone metastases can lead to a significantly decreased quality of life in these patients. Thus, it is essential to gain a better understanding of the molecular mechanisms that underlie the emergence and growth of b...

MetabolomicsHyaluronan catabolism supports the peritoneal disseminated metastasis of cancer through the glucuronic acid pathway
When disseminated into the peritoneal cavity at the very early stage, cancer cells must adapt to the glucose- and oxygen-limited environment in peritoneal fluid, yet the key molecular regulators remain undefined. Here, we reveal that early disseminated OC cells are ingeniously utilize hyaluronic aci...

TranscriptomicsTranscriptome of the bone metastasis associated stroma
The reciprocal interaction between cancer cells and the tissue-specific stroma is critical for primary and metastatic tumor growth progression. Prostate cancer cells colonize preferentially bone (osteotropism), where they alter the physiological balance between osteoblast-mediated bone formation and...

TranscriptomicsTH-MYCN Mice with Caspase-8 Deficiency Develop Advanced Neuroblastoma with Bone Marrow Metastasis
Neuroblastoma, the most common extracranial pediatric solid tumor, is responsible for 15% of all childhood cancer deaths. Patients frequently present at diagnosis with metastatic disease, particularly to the bone marrow. Advances in therapy and understanding of the metastatic process have been lim...

TranscriptomicsMechanisms and pathways of bone metastasis: challenges and pitfalls of performing molecular research on patient samples
The molecular mechanisms underlying the development of bone metastases in breast cancer remain unclear. Disseminated tumour cells (DTCs) in the bone marrow of breast cancer patients are commonly identified, even in early stage disease, but their potential to initiate metastases is not known. The mec...

TranscriptomicsGlobal analysis of metastasis-associated gene expression in the primary cultures from clinical specimens of ccRCC
Metastatic clear cell renal cell carcinoma (ccRCC) has a poor prognosis and unpredictable course and there are no molecular markers that reliably predict ccRCC metastasis. In this study, specimens from 84 patients with ccRCC were directly cultured in vitro. The primary cultures from 38 of 94 specime...
