    ..However, in whole liver these adaptive mechanisms of the mitochondria were inefficient at counteracting redox imbalances and inhibiting oxidative stress outside of the mitochondria. ..
  3. Martinez Velazquez M, Melendez Zajgla J, Maldonado V. Apoptosis induced by cAMP requires Smac/DIABLO transcriptional upregulation. Cell Signal. 2007;19:1212-20 pubmed
    ..These results show that cAMP is an important modulator of the apoptotic threshold in cancer cell by means of regulating Smac/DIABLO expression. ..
  4. Ceballos Cancino G, Espinosa M, Maldonado V, Melendez Zajgla J. Regulation of mitochondrial Smac/DIABLO-selective release by survivin. Oncogene. 2007;26:7569-75 pubmed
    ..These results provide an explanation for the observed differences in the release of mitochondrial intermembrane proteins in various apoptotic models and present a new mechanism for the anti-apoptotic effects of survivin in cancer cells. ..
  5. Tavares Carreón F, Camacho Villasana Y, Zamudio Ochoa A, Shingu Vazquez M, Torres Larios A, Perez Martinez X. The pentatricopeptide repeats present in Pet309 are necessary for translation but not for stability of the mitochondrial COX1 mRNA in yeast. J Biol Chem. 2008;283:1472-9 pubmed
    ..Our results show that the RNA metabolism function of Pet309 is found in at least two separate domains of the protein. ..
  6. Pruefer F, Lizarraga F, Maldonado V, Melendez Zajgla J. Participation of Omi Htra2 serine-protease activity in the apoptosis induced by cisplatin on SW480 colon cancer cells. J Chemother. 2008;20:348-54 pubmed
    ..05, but not to 5-FU p=0.49. From these experiments we show that Omi/Htra2 serine protease activity participates in the cell death induced by CDDP but not of 5-FU in colon cancer cells. ..
  7. Luévano Martínez L, Moyano E, de Lacoba M, Rial E, Uribe Carvajal S. Identification of the mitochondrial carrier that provides Yarrowia lipolytica with a fatty acid-induced and nucleotide-sensitive uncoupling protein-like activity. Biochim Biophys Acta. 2010;1797:81-8 pubmed publisher
    ..It is concluded that the XM_503525 gene from Y. lipolytica encodes for an oxaloacetate carrier although, remarkably, it also displays an uncoupling activity stimulated by fatty acids and inhibited by nucleotides. ..
  8. Colón M, Hernandez F, Lopez K, Quezada H, González J, López G, et al. Saccharomyces cerevisiae Bat1 and Bat2 aminotransferases have functionally diverged from the ancestral-like Kluyveromyces lactis orthologous enzyme. PLoS ONE. 2011;6:e16099 pubmed publisher
    ..lactis has been distributed in the two paralogous genes present in S. cerevisiae, and whether this conservation has impacted S. cerevisiae metabolism...
  9. Guerrero Castillo S, Araiza Olivera D, Cabrera Orefice A, Espinasa Jaramillo J, Gutiérrez Aguilar M, Luévano Martínez L, et al. Physiological uncoupling of mitochondrial oxidative phosphorylation. Studies in different yeast species. J Bioenerg Biomembr. 2011;43:323-31 pubmed publisher
    ..The variety of energy dissipating systems in eukaryote species is probably designed to control ROS production in the different environments where each species lives. ..
