MetabolomicsHypoxia Dependent Inhibition of Glioblastoma Cell Proliferation, Invasion, and Metabolism by the Choline-Kinase Inhibitor JAS239
Background: Elevated choline kinase alpha (ChoK) levels are observed in most solid tumors, including glioblastomas (GBM), and ChoK inhibitors have demonstrated limited efficacy in GBM models. Given that hypoxia is associated with resistance to GBM therapy, we hypothesized that tumor hypoxia c...

TranscriptomicsGenetic and transcriptome analyses of early T-cell checkpoint failure and leukemia initiation in Rag1-deficient NOD mice
Both immunodeficient and wild type NOD mice exhibit defects in control of early T-cell development in the thymus. We show that Rag1-deficient NOD mice fail to enforce both the b-selection checkpoint and an earlier T-cell commitment checkpoint, based on genome-wide genetic and transcriptome analyses....

ProteomicsCAMK2D recruits RNF8-MAD2 complex to RNA splicing proteins for mitotic checkpoint activation in GBM
Glioblastoma (GBM) is a lethal brain tumor with remarkable intra-tumoral heterogeneity and therapeutic resistance which is linked to glioma stem cell (GSC). GSC contains unstable genome and elevated genomic instability could impair GSC self-renewal and tumorigenicity. In addition, GSC displays great...

TranscriptomicsThe investigational Aurora kinase A inhibitor MLN8237 induces defects in cell viability and cell cycle progression in mouse bladder cancer cells in vitro and in vivo
PURPOSE: Despite over 70,000 new cases of bladder cancer in the United States annually, patients with advanced disease have a poor prognosis due to limited treatment modalities. We evaluate the role of Aurora A, identified as an upregulated candidate molecule in bladder cancer, in regulating bladde...

ProteomicsSelf-priming of Plk1 binding to BubR1 ensures accurate mitotic progression
Plk1 is a key mitotic kinase that localizes to distinct subcellular structures to promote accurate mitotic progression. Plk1 recruitment depends on direct interaction between polo-box domain (PBD) on Plk1 and PBD binding motif (PBD BM) on the interactors. However, recent study showed that PBD BM alo...

TranscriptomicsTRRAP-mediated regulation of Wee1
The G2 DNA damage checkpoint inhibits Cdc2 and mitotic entry through the dual regulation of Wee1 and Cdc25 by the Chk1 effector kinase. Up-regulation of Chk1 by mutation or overexpression bypasses the requirement for up-stream regulators or DNA damage to promote a G2 cell cycle arrest. We screened i...

TranscriptomicsTranscription profiling of human fibroblasts subjected to DNA damage reveals ATM-dependent regulation of gene expression
The relationships between profiles of global gene expression and DNA damage checkpoint functions were studied in cells from patients with ataxia telangiectasia (AT). Three telomerase-expressing AT fibroblast lines displayed the expected hypersensitivity to ionizing radiation (IR) and defects in DNA...
