Using unbiased kinase profiling, we identified protein kinase A (PKA) as an active kinase in small cell lung cancer (SCLC). Inhibition of PKA activity genetically, or pharmacologically by activation of the PP2A phosphatase, inhibits SCLC expansion in culture and in vivo. Conversely, GNAS (G-protein ...

Genetic alterations that activate protein kinase A (PKA) signaling are found across many tumor types, but their downstream oncogenic mechanisms are poorly understood. We used global phosphoproteomics and kinome activity profiling to map the conserved signaling outputs driven by diverse genetic chang...

Alginate overproduction by P. aeruginosa, also known as mucoidy is associated with chronic endobronchial infections in cystic fibrosis (CF). Alginate biosynthesis in this bacterium is initiated by the extracytoplasmic function sigma factor (σ22, AlgU/T). In the wild type (wt) nonmucoid strains, su...

Hoxc13 has been shown to be essential for proper hair shaft differentiation as Hoxc13 gene-targeted (Hoxc13tm1Mrc) mice completely lack external hair. Because of the phenotypic parallels to the Foxn1nu (nude) mutant mice, we tested whether Hoxc13 and Foxn1 act in a common pathway of hair follicle (H...
