TranscriptomicsAn RNAi Screen Identifies TRRAP as a Regulator of Brain Tumor-Initiating Cell Differentiation
Glioblastoma multiforme is the most common and most aggressive type of primary brain tumor. The brain-infiltrative character of glioblastoma makes complete surgical removal of the tumor impossible and neither radiation nor current chemotherapy provide cure. Recent evidence shows that glioblastoma mu...

MetabolomicsOVCAR-3 spheroid-derived cells display distinct metabolic profiles
Recently, multicellular spheroids were isolated from a well-established epithelial ovarian cancer cell line, OVCAR-3, and were propagated in vitro. These spheroid derived cells displayed numerous hallmarks of cancer stem cells, which are chemo and radioresistant cells thought to be a significant cau...

TranscriptomicsGrowth inhibition of ovarian tumor-initiating cells by niclosamide
The gene expression profile in treated CP70 side population spheroid cells (CP70sps cells) was analyzed to investigate the effect of niclosamide inhibition on ovarian tumor-initiating cells. CP70sps cells are isolated and characterized as one kind of ovarian tumor-initiating cells, and they show ste...

TranscriptomicsTranscription profiling of mouse mammary tumor-initiating cells
Using a syngeneic p53 null mouse mammary gland tumor model that closely mimics human breast cancer, we have identified by limiting dilution transplantation as well as in vitro mammosphere and clonogenic assays a Lin-CD29HighCD24High subpopulation of tumor-initiating cells. Differentially expressed ...

TranscriptomicsBrain tumor initiating cell response to microglia
Determination of the mechanism by which microglia regulate growth of brain tumor initiating cells (BTICs) and differentiation. Results identify the factors involved in the regulation and provide mechanistic basis. We subjected brain tumor initiating cells to microarray to determine the genes involve...

TranscriptomicsTargeting Unique Metabolic Properties of Breast Tumor Initiating Cells
Bulk cancer cell populations are known to display distinct metabolic properties compared to their normal counterparts. However, relatively little is known about heterogeneity of metabolic properties within tumors. In this study we show that, analogous to some normal stem cells, breast tumor initiati...

ProteomicsFunctional states in tumor-initiating cell differentiation in human colorectal cancer
Intra-tumor heterogeneity of tumor-initiating cell (TIC) activity drives colorectal cancer (CRC) progression and therapy resistance. Here, we used single-cell mRNA-sequencing (scRNA-seq) of patient-derived CRC models to decipher distinct cell subpopulations based on their transcriptional profiles. C...

MetabolomicsPharmacological Targeting of ALDH1a2 in Dendritic Cells Enhances Antigen Presentation, T Cell Activation and Anti-tumor immunity
Dendritic cell (DC) vaccines have been proposed as cancer immunotherapies due to their role as crucial antigen-presenting cells that regulate T cell functions. Despite considerable efforts to optimize ex vivo priming of DCs, DC vaccines have rarely been successful, suggesting the presence of unknown...

MetabolomicsMitochondrial Transplantation of Brown Adipocytes Interferes with the Metabolism of Tumor Stem Cells and Inhibits the Recurrence of Brain Glioma after Operation

Glioblastoma multiforme (GBM) is highly aggressive, with treatment resistance and recurrence driven by metabolically plastic glioma stem cells (GSCs). Inspired by brown adipose tissue (BAT) thermogenesis, researchers transplanted BAT-derived mitochondria (BA-Mito) into GSCs, reducing stemness mar...

TranscriptomicsRapid reprogramming of primary human astrocytes into potent tumor initiating cells with defined genetic factors
Cancer stem cells play key roles in human malignancies. However, their cellular and molecular origins are still poorly understood. Here we report the successful generation of cancer stem cells from primary human astrocytes by use of defined genetic factors. Combined transduction of four factors —m...
