MetabolomicsLactate controls cancer stemness and plasticity through epigenetic regulation.

Tumours arise from uncontrolled cell proliferation driven by mutations in genes that regulate stem cell renewal and differentiation. Intestinal tumours, however, retain some hierarchical organization, maintaining both cancer stem cells (CSCs) and cancer differentiated cells (CDCs). This heterogen...

MetabolomicsExtracellular-acidosis restricts one-carbon metabolism and preserves T cell stemness
The accumulation of acidic metabolic waste products within the tumor microenvironment profoundly inhibits effector functions of tumor-infiltrating lymphocytes (TILs). However, it is unclear whether extracellular-acidosis impacts T cell metabolic fitness and differentiation status. Here, we surprisin...

MetabolomicsCommon Metabolic Pathways Implicated in Resistance to Chemotherapy Point to a Key Mitochondrial Role in Breast Cancer
Cancer cells are known to reprogram their metabolism to adapt to adverse conditions dictated by tumor growth and microenvironment. A subtype of cancer cells with stem-like properties, known as cancer stem cells (CSC), is thought to be responsible for tumor recurrence. In this study, we demonstrated ...

TranscriptomicsMyeloid derived suppressor cells enhance stemness of cancer cells by inducing miRNA101 and suppressing the corepressor CtBP2
The work identifies an immune associated cellular, molecular and clinical network involving MDSCs-microRNA101-CtBP2-stem cell core genes, which extrinsically controls cancer stemness and impacts patient outcome. Primary ovarian cancer cells (5 x105) were co-cultured with freshly sorted ovarian cance...

TranscriptomicsCancer-Associated Fibroblasts Support Lung Cancer Stemness through Paracrine IGF-II/IGF1R/Nanog Signaling
The CLS1/CAF co-culture maintained the cancer stemness. This cancer stemness was lost when the CAF feeder cells were removed during passaging. To investigate the specific signaling pathways and markers of lung CSCs, we analyzed the gene expression profile of the CLS1 sphere after CLS1/CAF co-cultur...

TranscriptomicsEpigenetic Maintenance of Stemness and Malignancy in Peripheral Neuroectodermal Tumors by EZH2
Chromatin modifications are increasingly recognized as a key mechanism in cancer. The histone methyl-transferase Enhancer of Zeste, Drosophila, Homolog 2 (EZH2) is the enzymatic subunit of the polycomb PRC2 complex and methylates histone H3K27, thereby, mediating gene silencing. Down-regulation of E...

TranscriptomicsTranscriptional profiling of PKH26-labeled colorectal cancer stem cells
Quiescent cancer cells responsible for tumor chemoresistance and relapse have been identified in several tumors but in colorectal cancer (CRC) they remain largely undefined. By using a proliferation-sensitive dye, we isolated and characterized a rare subpopulation of cells from colorectal tumors whi...

ProteomicsCPT1A-mediated MFF succinylation promotes stemness maintenance in ovarian cancer stem cells
Cancer stem cells (CSCs) play crucial roles in cancer progression, immune evasion, drug resistance, and recurrence. Understanding the mechanisms behind CSCs generation and stemness maintenance is vital for early cancer diagnosis and treatment. Here, we unveil that carnitine palmitoyltransferase 1A (...

ProteomicsSOX4 supports cancer stemness by enhancing HDAC1 transcription revealed by comparative proteomics
We have investigated the proteome changes induced by SOX4 overexpression in HCT-116 cells using iTRAQ-based quantitative proteomics. Bioinformatics analysis revealed that HDAC1 could be one of the important regulators in cancer stem cells (CSCs) maintenance. We found that SOX4 transcriptionally regu...

ProteomicsSmall extracellular vesicles-delivered LSD1 promotes gastric cancer cell stemness
Although there are plenty of researches about nucleic acid in small extracellular vesicles (sEVs), properties of proteins identified as sEVs’ cargos and the mechanism of their action in recipient cell are poorly understood. Here, we show that lysine specific demethylase 1 (LSD1), the first identifie...
