Cell survival was measured by platting effectiveness as described above. ROS production and propidiumiodide discoloration were monitored by flow cytometry. Labelling with PI was performed by incubating 106 cells in culture medium containing 2 ug/ml of PI for 15 min. ROS creation was monitored in cells protecting plasma membrane integrity by double staining with PI and dichlorodihydrofluorescein diacetate. Transformation of H2DCFDA to DCF was analysed in PI negative cells. About 106 cells were incubated in culturemediumcontaining 40 ug/mlH2DCFDAfor 4-5 min at 30 C. 2 ug/ml of PI was added after 30min of incubation. Flow cytometric Anastrozole solubility analysis was done in a Epics XLTM flow cytometer built with an ion laser emitting a 488 nm column at 15mW. Natural fluorescence was collected through a 488 nm preventing filter, a nm long pass dichroic and a 525 nm band pass filter. Red fluorescence was collected via a 560 nm short pass dichroic, a nm longpass, and still another 670 nmlong pass filter. 20,000 cellswere analysed per sample at low flow rate. Data were analysed by WinMDI 2. 8 pc software. Cells indicating PKC, Bax c myc, PKC and Bax c myc o-r nothing of the proteins were co altered with pCLbGFP. Cells Eumycetoma were collected at differing times and fragmentation of the network assessed by epifluorescence microscopy. At least 150 cells per sample were classified. In this set of tests uracil was also omitted from the growth medium. Cells extracts were prepared as described in ref.. Protein lysates were separated on 12. Five hundred SDS PAGE gels and transferred to polyvinylidene fluoride membranes. The membranes were blocked with five minutes non fat milk in phosphatebuffered saline containing 0. 0-5 Tween 20 for 30 min at room temperature. Membraneswere then incubated overnight at 4 Cwith primary anti-bodies directed against human Bax, bovine PKC, yeast phosphoglycerate kinase, yeast Atg8p, GFP or yeast Por1p. Peroxidase coupled secondary antibodies were from Jackson ImmunoResearch Laboratories and membranes were incubated for 1 h at room temperature. Peroxidase activity was revealed by chemioluminescence. Mitochondria were isolated by differential centrifugation from zymolyase addressed cells, as described previously. For carbonate and Triton X 100 removal, 1 mg of protein from isolated mitochondria was incubated in the presence of 0. 1 M Na2CO3 o-r Triton X 100 for 15 min and centrifuged for 15 min at 105,000?g. The current presence of Bax d myc in the supernatant and the pellet was tested by Western blot. Evaluation of cyt c content was measured by redox spectra of isolated mitochondria basically as described previously.
