A method to isolate fragments of DNA that promote gene expression in Bacillus subtilis is described. The system is based on production of catechol 2,3-dioxygenase [CatO2ase; catechol:oxygen 2,3-oxidoreductase (decyclizing), EC] encoded by the Pseudomonas putida TOL plasmid gene xylE. The gene was transferred to aB. subtilis/Escherichia coli(More)
Cleavage of the full-length mutant huntingtin (mhtt) protein into smaller, soluble aggregation-prone mhtt fragments appears to be a key process in the neuropathophysiology of Huntington's Disease (HD). Recent quantification studies using TR-FRET-based immunoassays showed decreasing levels of soluble mhtt correlating with an increased load of aggregated mhtt(More)
The mitogen-activated protein kinases (MAPKs) extracellular signal-regulated protein kinase (ERK)1 and ERK2, involved in regulating cell growth and differentiation, are constitutively active in A375 and WM239 human melanoma cells. Using PD098059, an inhibitor of MAPK kinase (MEK), we investigated the role of persistently activated ERK1/2 in cell growth. The(More)
