Nitrostyrene derivatives act as RXR{alpha} ligands to inhibit TNF{alpha} activation of NF{kappa}B

Retinoid X receptor alpha (RXRα) and its N-terminally truncated version - tRXRα are widely implicated in cancer development and represent intriguing targets for cancer prevention and treatment. Successful manipulation of RXRα and tRXRα requires the...

Molecular Drivers of Muscle-Invasive Bladder Cancer

Muscle-invasive urothelial carcinomas of the bladder (MIUCB) exhibit frequent receptor tyrosine kinase alterations, but the precise nature of their contributions to tumor pathophysiology is unclear. Using mutant HRAS (HRAS*) as an oncogenic prototype,...

Oncogenic HRAS activates epithelial-mesenchyme transition and confers stemness to p53-deficient urothelial cells to drive muscle invasion of basal subtype carcinomas

Muscle-invasive urothelial carcinomas of the bladder (MIUCB) exhibit frequent receptor tyrosine kinase alterations but the precise nature of their contributions to tumor pathophysiology is unclear. Using mutant HRAS (HRAS*) as an oncogenic prototype, w...

IDH and NPM Mutations Cooperate to Maintain AML Stem Cells

IDH1 and IDH2 mutations occur frequently in acute myeloid leukemia (AML) and other cancers. The mutant isocitrate dehydrogenase (IDH) enzymes convert α-ketoglutarate (α-KG) to the oncometabolite 2-hydroxyglutarate (2-HG), which dysregulates a set of...

IDH2 and NPM1 mutations cooperate to activate Hoxa9/Meis1 and hypoxia pathways in acute myeloid leukemia

IDH1 and IDH2 mutations occur frequently in acute myeloid leukemia (AML) and other cancers. The mutant IDH enzymes convert α-ketoglutarate (α-KG) to the oncometabolite 2-hydroxyglutarate (2-HG), which dysregulates a set of α-KG-dependent dioxygenase...
