PURPOSE The effects of the heat shock protein 90 (Hsp90) inhibitor geldanamycin (GA) were examined on the radiosensitivity and signal transduction pathways in human tumour cell lines. MATERIALS AND METHODS Two human cell lines, SQ-5 and DLD-1, derived from lung carcinoma and colon adenocarcinoma, respectively, were incubated for 16 h at 37 degrees C in(More)
A dibenzofuran (DF)-degrading bacterium, Nocardioides sp. DF412, was isolated and its genes responsible for the degradation of DF were cloned and characterized. The dfdA1A2A3A4 gene cluster coding for a ring hydroxylating dioxygenase was located on a plasmid, and the dfdBC gene cluster coding for a ring-cleavage dioxygenase and a following hydrolase(More)
