Anti-Cdc2 antibody (PSTAIRE; Sigma Chemical) was used as loading

Anti-Cdc2 antibody (PSTAIRE; Sigma Chemical) was used as loading control. Northern blot analysis Aliquots of the cultures were recovered at different times, total RNA preparations obtained and resolved through 1.5% agarose-formaldehyde gels, and hybridizations were performed as previously described [35]. The probes employed were a 2.1 Kbp fragment of the pyp2 + gene amplified by PCR with the 5′ oligonucleotide CCGAGAGCGTTTCTTGGA and the 3′ oligonucleotide AAGGGCTTGGAAGCCTGG, a 1 Kbp fragment of the fbp1 + gene amplified with the 5′oligonucleotide CTTCCAAGCCAAATACTG and the 3′oligonucleotide GATCTCGACGAAATCGAC, and a 1 Kbp fragment

of the leu1 + gene amplified with the 5′ oligonucleotide TCGTCGTCTTACCAGGAG and the 3′ oligonucleotide CAACAGCCTTAGTAATAT. Ready-To-Go DNA labelling beads and the Rapid-Hyb buffer learn more (GE Healthcare) were used for DNA labeling and hybridization, respectively. mRNA levels were quantified in a Phosphorimager (Molecular Dynamics) and compared with the internal control (leu1 + mRNA). Plate assay of sensitivity for growth Wild-type and mutant strains of S. pombe were grown in YES liquid medium (7% glucose) to an OD600= 0.6. Appropriate dilutions were spotted per duplicate on YES solid medium supplemented with either 7% glucose or 2% glycerol plus 3% ethanol, and

in the presence/absence of 30 mM NAC. Plates were incubated at 28°C for 5 days and then photographed. Reproducibility of results All experiments were repeated at least three times. Depending on the experiment, mean relative units + SD PCI 32765 and/or representative results are shown.
