Interleukin 2 transcription factors as molecular targets of cAMP inhibition: delayed inhibition kinetics and combinatorial transcription roles [PDF]
, 1994 Elevation of cAMP can cause gene-specific inhibition of interleukin 2 (IL-2) expression. To investigate the mechanism of this effect, we have combined electrophoretic mobility shift assays and in vivo genomic footprinting to assess both the availability ...

Engineering a bioluminescent indicator for cyclic AMP-dependent protein kinase [PDF]
Biochemical Journal, 1991 cDNA coding for the luciferase in the firefly Photinus pyralis was amplified in vitro to generate cyclic AMP-dependent protein kinase phosphorylation sites. The DNA was transcribed and translated to generate light-emitting protein. A valine at position 217 was mutated to arginine to generate a site RRFS and the heptapeptide kemptide, the ...

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma
Molecular Oncology, EarlyView.We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Inhibition of TBK1/IKKε Promotes Regeneration of Pancreatic β-cells
Scientific Reports, 2018 β-cell proliferation induction is a promising therapeutic strategy to restore β-cell mass. By screening small molecules in a transgenic zebrafish model of type 1 diabetes, we identified inhibitors of non-canonical IκB kinases (IKKs), TANK-binding kinase ...

Redox regulation meets metabolism: targeting PRDX2 to prevent hepatocellular carcinoma
Molecular Oncology, EarlyView.PRDX2 acts as a central redox hub linking metabolic dysfunction‐associated steatohepatitis (MASH) to hepatocellular carcinoma (HCC). In normal hepatocytes, PRDX2 maintains redox balance and metabolic homeostasis under oxidative stress. In contrast, during malignant transformation, PRDX2 promotes oncogenic signaling, stemness, and tumor initiation ...

Cofactor Fingerprinting with STD NMR to Characterize Proteins of Unknown Function: Identification of a Rare cCMP Cofactor Preference [PDF]
, 2004 Proteomics efforts have created a need for better strategies to functionally categorize newly discovered proteins. To this end, we have employed saturation transfer difference NMR with pools of closely related cofactors, to determine cofactor preferences.

Phosphorylation of β-Catenin by Cyclic AMP-dependent Protein Kinase [PDF]
Journal of Biological Chemistry, 2006 Beta-catenin is a signaling molecule that promotes cell proliferation by the induction of gene transcription through the activation of T-cell factor (TCF)/lymphoid enhancer factor (LEF) transcription factors. The canonical mechanism of the regulation of beta-catenin involves its phosphorylation by casein kinase 1 at the Ser-45 site and by glycogen ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Cyclic AMP binding proteins and cyclic AMP-dependent protein kinase from Blastocladiella emersonii [PDF]
Journal of Bacteriology, 1978 The stoichiometry of cyclic AMP binding protein to cyclic AMP in sporulating cells of Blastocladiella emersonii and the resistance of protein-bound cyclic AMP to enzyme-catalyzed hydrolysis suggest that the distribution of cyclic AMP between free and protein-bound pools is an important factor in cyclic AMP metabolism. Most but not all of the cyclic AMP
