The switch between stem/progenitor cell expansion and differentiation is critical for organ homeostasis. The mammalian Hippo pathway effector and oncoprotein YAP expands undifferentiated stem/progenitor cells in various tissues. However, the YAP-associated transcription factors and downstream targets underlying this stemness-promoting activity are poorly understood. Here we show that the SRF-IL...
Targeting cancer stem cells (CSCs) in colorectal cancer (CRC) remains a difficult problem, as the regulation of CSCs in CRC is poorly understood. Here we demonstrated that KCTD12, potassium channel tetramerization domain containing 12, is down-regulated in the CSC-like cells of CRC. The silencing of endogenous KCTD12 and the overexpression of ectopic KCTD12 dramatically enhances and represses C...
Background. Human embryonic stem cells (hESCs) are pluripotent cells derived from the inner cell mass of in vitro fertilised blastocysts, which can either be maintained in an undifferentiated state or committed into lineages under determined culture conditions. These cells offer great potential for regenerative medicine, but at present, little is known about the mechanisms that regulate hESC st...
Human embryonic stem cells (hESCs) have been reported to exert cytoprotective activity in the area of tissue injury. However, hypoxia/oxidative stress prevailing in the area of injury could activate p53, leading to death and differentiation of hESCs. Here we report that when exposed to hypoxia/oxidative stress, a small fraction of hESCs, namely the SSEA3+/ABCG2+ fraction undergoes a transient s...
objective: ecstasy, or 3, 4 (±) methylenedioxymethamphetamine (mdma), is a potent neurotoxic drug. one of the mechanisms for its toxicity is the secondary release of glutamate. mouse embryonic stem cells (mescs) express only one glutamate receptor, the metabotropic glutamate receptor 5 (mglu5), which is involved in the maintenance and self-renewal of mescs. this study aims to investigate whethe...
Stemness Revisited: A Meta Analysis of Stem Cell Signatures Using High-Throughput Data Integration
Abstract Background Additional epidermal growth factor receptor (EGFR) mutations confer the drug resistance to generations of EGFR targeted tyrosine kinase inhibitor (EGFR-TKI), posing a major challenge developing effective treatment lung adenocarcinoma (LUAD). The strategy combining EGFR-TKI with other synergistic or sensitizing therapeutic agents are considered promising approach in era preci...
