MetabolomicsSpatially-guided metabolomics profiling of heterogeneous human tumor tissues

Bulk high-resolution mass spectrometry can provide sensitive and global snapshots of metabolites involved in cancer metabolism. However, intra-tumor heterogeneity (IntraTH) convolutes the cellular origins and tumor pathologies associated with the detected metabolites, thus making the elucidation ...

MetabolomicsHif1α-Dependent Uncoupling Of Glycolysis Suppresses Tumor Cell Proliferation
Hypoxia-inducible factor-1α (HIF1α) attenuates mitochondrial activity while promoting glycolysis. Paradoxically, it remains unknown why lower glycolysis is compromised in human clear cell renal cell carcinomas (ccRCC), in which HIF1α acts a tumor suppressor by inhibiting cell autonomous proliferatio...

MetabolomicsSingle-cell metabolic fingerprints discover a cluster of circulating tumor cells with distinct metastatic potential

Circulating tumor cells (CTCs) are recognized as direct seeds of metastasis. However, CTC count may not be the 'best' indicator of metastatic risk because their heterogeneity is generally neglected. In this study, we develop a molecular typing system to predict colorectal cancer metastasis potent...

MetabolomicsDynamic single-cell metabolomics reveals cell-cell interaction between tumor cells and macrophages

Single-cell metabolomics reveals cell heterogeneity and elucidates intracellular molecular mechanisms. However, general concentration measurement of metabolites can only provide a static delineation of metabolomics, lacking the metabolic activity information of biological pathways. Herein, we dev...

TranscriptomicsLiquid Biopsy-Based Single-Cell Transcriptome Profiling Characterizes Heterogeneity of Disseminated Tumor Cells from Lung Adenocarcinoma
To decipher the heterogeneity and distinct molecular signatures of disseminated tumor cells, we profiled the transcriptomes single cells from malignant pleural effusion. RNA-seq was done using the standard 10x chromium v3 chemistry.

ProteomicsQuantifying Cell Heterogeneity and Subpopulations Using Single Cell Metabolomics
We combined the Single-probe single cell MS(SCMS) experimental technique with a bioinformatics software package, SinCHet-MS (Single Cell Heterogeneity for Mass Spectrometry), to characterize changes of tumor heterogeneity, quantify cell subpopulations, and prioritize the metabolite biomarkers of eac...

ProteomicsAPOBEC mutagenesis and copy number alterations are drivers of proteogenomic tumor evolution and heterogeneity in metastatic thoracic tumors
Intratumor mutational heterogeneity has been documented in primary non-small cell lung cancer. Here, we elucidate mechanisms of tumor evolution and heterogeneity in metastatic thoracic tumors (lung adenocarcinoma and thymic carcinoma) using whole-exome and transcriptome sequencing, SNP array for cop...

TranscriptomicsGenetic Heterogeneity in Mouse Mammary Tumors
Human cancers result from a complex series of genetic alterations resulting in heterogeneous disease states. Dissecting this heterogeneity is critical for understanding underlying mechanisms and providing opportunities for therapeutics matching the complexity. Mouse models of cancer have generally b...

TranscriptomicsReactivation of multipotency by oncogenic PIK3CA induces breast tumor heterogeneity
Breast cancer is the most frequent cancer in women and consists of heterogeneous types of tumours that are classified into different histological and molecular subtypes1-3. Pik3ca and p53 are the two most frequently mutated genes and are associated with different types of human breast cancers4. The ...

ModelsAlvarez2019 - A nonlinear mathematical model of cell-mediated immune response for tumor phenotypic heterogeneity
This is a non-linear mathematical model of cancer immunosurveillance that takes into account intratumoral phenotypic heterogeneity, such as differential expression of cell surface receptors and growth factors, according to cell-mediated immune responses. The model describes phenomena that have also ...
