Gliotoxin from Aspergillus chevalieri (Mangin) Thom et Church

Self-Protection against Gliotoxin—A Component of the Gliotoxin Biosynthetic Cluster, GliT, Completely Protects Aspergillus fumigatus Against Exogenous Gliotoxin

Gliotoxin, and other related molecules, are encoded by multi-gene clusters and biosynthesized by fungi using non-ribosomal biosynthetic mechanisms. Almost universally described in terms of its toxicity towards mammalian cells, gliotoxin has come to be considered as a component of the virulence arsenal of Aspergillus fumigatus. Here we show that deletion of a single gene, gliT, in the gliotoxin ...

Gliotoxin Isolated from Marine Fungus Aspergillus sp. Induces Apoptosis of Human Cervical Cancer and Chondrosarcoma Cells

Gliotoxin, a secondary metabolite produced by marine fungus Aspergillus sp., possesses various biological activities including anticancer activity. However, the mechanism underlying gliotoxin-induced cytotoxicity on human cervical cancer (Hela) and human chondrosarcoma (SW1353) cells remains unclear. In this study, we focused on the effect of gliotoxin induction on apoptosis, the activating exp...

GliA in Aspergillus fumigatus is required for its tolerance to gliotoxin and affects the amount of extracellular and intracellular gliotoxin.

Gliotoxin is an important virulence factor of Aspergillus fumigatus. Although GliA putatively belongs to the major facilitator superfamily in the gliotoxin biosynthesis cluster, its roles remain unclear. To determine the function of GliA, we disrupted gliA in A. fumigatus. gliA disruption increased the susceptibility of A. fumigatus to gliotoxin. The gliT and gliA double-disrupted mutant had ev...

Mangin on QOF.

I am no great lover of the Quality and Outcomes Framework (QOF) introduced to general practice for payment from the NHS. However I believe that the thrust of Mangin and Toop's editorial 1 in the June 2007 issue is wrong. I can see how the QOF may appear to some to lead British GPs to coerce patients into accepting care that they do not want, but I do not believe that this is inevitable. I dispu...
