NSUN2 is a glucose sensor suppressing cGAS/STING to maintain tumorigenesis and immunotherapy resistance.

Journal Article Cell Metab · October 3, 2023 Glucose metabolism is known to orchestrate oncogenesis. Whether glucose serves as a signaling molecule directly regulating oncoprotein activity for tumorigenesis remains elusive. Here, we report that glucose is a cofactor binding to methyltransferase NSUN2 ... Full text Link to item Cite

Identification of myo-inositol-binding proteins by using the biotin pull-down strategy in cultured cells.

Journal Article STAR Protoc · June 17, 2022 Metabolites are not only substrates in metabolic reactions, but they also serve as signaling molecules to regulate diverse biological functions. Identification of the binding proteins for the metabolites helps in the understanding of their functions beyond ... Full text Open Access Link to item Cite

SIRPγ-expressing cancer stem-like cells promote immune escape of lung cancer via Hippo signaling.

Journal Article J Clin Invest · March 1, 2022 Cancer stem-like cells (CSLCs) acquire enhanced immune checkpoint responses to evade immune cell killing and promote tumor progression. Here we showed that signal regulatory protein γ (SIRPγ) determined CSLC properties and immune evasiveness in a small pop ... Full text Open Access Link to item Cite

Inositol serves as a natural inhibitor of mitochondrial fission by directly targeting AMPK.

Journal Article Mol Cell · September 16, 2021 Mitochondrial dynamics regulated by mitochondrial fusion and fission maintain mitochondrial functions, whose alterations underline various human diseases. Here, we show that inositol is a critical metabolite directly restricting AMPK-dependent mitochondria ... Full text Open Access Link to item Cite

Author Correction: SETDB1-mediated methylation of Akt promotes its K63-linked ubiquitination and activation leading to tumorigenesis.

Journal Article Nat Cell Biol · June 2021 A Correction to this paper has been published: ... Full text Link to item Cite

The Skp2 Pathway: A Critical Target for Cancer Therapy.

Journal Article Semin Cancer Biol · December 2020 Strictly regulated protein degradation by ubiquitin-proteasome system (UPS) is essential for various cellular processes whose dysregulation is linked to serious diseases including cancer. Skp2, a well characterized component of Skp2-SCF E3 ligase complex, ... Full text Open Access Link to item Cite

Phosphorylation of PDHA by AMPK Drives TCA Cycle to Promote Cancer Metastasis.

Journal Article Mol Cell · October 15, 2020 Cancer metastasis accounts for the major cause of cancer-related deaths. How disseminated cancer cells cope with hostile microenvironments in secondary site for full-blown metastasis is largely unknown. Here, we show that AMPK (AMP-activated protein kinase ...

Increased activation of HDAC1/2/6 and Sp1 underlies therapeutic resistance and tumor growth in glioblastoma.

Journal Article Neuro Oncol · October 14, 2020 BACKGROUND: Glioblastoma is associated with poor prognosis and high mortality. Although the use of first-line temozolomide can reduce tumor growth, therapy-induced stress drives stem cells out of quiescence, leading to chemoresistance and glioblastoma recu ...

Lactate Is a Natural Suppressor of RLR Signaling by Targeting MAVS.

Journal Article Cell · June 27, 2019 RLR-mediated type I IFN production plays a pivotal role in elevating host immunity for viral clearance and cancer immune surveillance. Here, we report that glycolysis, which is inactivated during RLR activation, serves as a barrier to impede type I IFN pro ... Full text Open Access Link to item Cite

SETDB1-mediated methylation of Akt promotes its K63-linked ubiquitination and activation leading to tumorigenesis.

Journal Article Nat Cell Biol · February 2019 The serine/threonine kinase Akt plays a central role in cell proliferation, survival and metabolism, and its hyperactivation is linked to cancer progression. Here we report that Akt undergoes K64 methylation by SETDB1, which is crucial for cell membrane re ... Full text Link to item Cite

Stress stimuli induce cancer-stemness gene expression via Sp1 activation leading to therapeutic resistance in glioblastoma.

Journal Article Biochem Biophys Res Commun · November 4, 2017 It has been suggested that stress stimuli from the microenvironment maintain a subset of tumor cells with stem-like properties, including drug resistance. Here, we investigate whether Sp1, a stress-responsive factor, regulates stemness gene expression and ... Full text Link to item Cite

Specificity protein 1-modulated superoxide dismutase 2 enhances temozolomide resistance in glioblastoma, which is independent of O6-methylguanine-DNA methyltransferase.

Journal Article Redox Biol · October 2017 Acquisition of temozolomide (TMZ) resistance is a major factor leading to the failure of glioblastoma (GBM) treatment. The exact mechanism by which GBM evades TMZ toxicity is not always related to the expression of the DNA repair enzyme O6-methylguanine-DN ... Full text Link to item Cite

Suberoylanilide hydroxamic acid represses glioma stem-like cells.
