MetabolomicsAMPK activation orchestrated replicative senescence of periodontal ligament stem cells via regulating metabolomics

BACKGROUND: Periodontal ligament mesenchymal stem cells (PDLSCs) are a promising cell resource for cell-based regenerative medicine in dentistry. PDLSCs inevitably acquire a senescent phenotype after prolonged in vitro expansion, and the key regulators of cells during replicative...

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...

MetabolomicsEMP1 safeguards hematopoietic stem cells by suppressing sphingolipid metabolism and alleviating endoplasmic reticulum stress
The long-term maintenance of hematopoietic stem cells (HSCs) relies on the regulation of endoplasmic reticulum (ER) stress at a low level, but the underlying mechanism remains poorly understood. Here, we demonstrate that suppression of ER stress improves the functions of HSCs and protects HSCs again...

MetabolomicsHuman umbilical cord-derived mesenchymal stem cells ameliorate perioperative neurocognitive disorder by inhibiting inflammatory responses and activating BDNF/TrkB/CREB signaling pathway in aged mice

BACKGROUND: Perioperative neurocognitive disorder (PND) is a key complication affecting older individuals after anesthesia and surgery. Failure to translate multiple pharmacological therapies for PND from preclinical studies to clinical settings has necessitated the exploration o...

MetabolomicsDistinct metabolic responses of an ovarian cancer stem cell line

Background

Cancer metabolism is emerging as an important focus area in cancer research. However, the in vitro cell culture conditions under which much cellular metabolism research is performed differ drastically from in vivo tumor conditions, which are characterized by variations in the leve...

MetabolomicsOld mitochondria regulate niche renewal via stem cell metabolism
Cellular metabolism is emerging as a potent regulator of cell fate, raising the possibility that the recently discovered metabolic heterogeneity between newly synthesized and chronologically old organelles may impact stem cell fate in mammalian tissues. The small intestine is maintained by actively ...

Metabolomics1H NMR metabolite monitoring during the differentiation of human induced pluripotent stem cells provides new insights into the molecular events that regulate embryonic chondrogenesis
The integration of cell metabolism with signalling pathways, transcription factor networks and epigenetic mediators is critical in coordinating molecular and cellular events during embryogenesis. Induced pluripotent stem cells (IPSCs) are an established model for embryogenesis, germ layer specificat...

MetabolomicsExtracts from sweet sorghum (Sorghum bicolor), a feedstock for biorefining, suppressed proliferation and elevated apoptosis in human colon cancer stem cells via suppression of Wnt/beta-catenin signaling pathway
In colorectal cancer, p53 is commonly inactivated, associated with chemo-resistance, and marks the transition from non-invasive to invasive disease. Cancers, including colorectal cancer, are thought to be diseases of aberrant stem cell populations, as stem cells are able to self-renew, making them l...
