Biphasic modulation of fatty acid synthase by hydrogen peroxide in Saccharomyces cerevisiae
Matias, Ana C.; Marinho, H. Susana; Cyrne, Luísa; Herrero Perpiñán, Enrique; Antunes, Fernando (Elsevier, 2011)Taking into account published contradictory results concerning the regulation of fatty acid synthase (Fas) by H2O2, we carried out a systematic study where two methods of H2O2 delivery (steady-state and bolus addition) ... -
Down-regulation of fatty acid synthase increases the resistance of Saccharomyces cerevisiae cells to H2O2
Matias, Ana C.; Pedroso, Nuno; Teodoro, Nuno; Marinho, H. Susana; Antunes, Fernando; Nogueira, José Manuel; Herrero Perpiñán, Enrique; Cyrne, Luísa (Elsevier, 2007)Changes in plasma membrane permeability caused by H2O2 were recently found to be involved in the adaptation to H2O2, but the mechanism responsible for this change remains largely unknown. Here this mechanism was addressed ... -
Modulation of plasma membrane lipid profile and microdomains by H2O2 in Saccharomyces cerevisiae
Pedroso, Nuno; Matias, Ana C.; Cyrne, Luísa; Antunes, Fernando; Borges, Carlos; Malhó, Rui; de Almeida, Rodrigo F.M.; Herrero Perpiñán, Enrique; Marinho, H. Susana (Elsevier, 2009)In Saccharomyces cerevisiae, the rate of hydrogen peroxide (H2O2) diffusion through the plasma membrane decreases during adaptation to H2O2 by a still unknown mechanism. Here, adaptation to H2O2 was observed to modulate ...
