Genetic manipulation of longevity-related genes as a tool to regulate yeast life span and metabolite production during winemaking

2013

Abstract Background Yeast viability and vitality are essential for different industrial processes where the yeast Saccharomyces cerevisiae is used as a biotechnological tool. Therefore, the decline of yeast biological functions during aging may compromise their successful biotechnological use. Life span is controlled by a variety of molecular mechanisms, many of which are connected to stress tolerance and genomic stability, although the metabolic status of a cell has proven a main factor affecting its longevity. Acetic acid and ethanol accumulation shorten chronological life span (CLS), while glycerol extends it. Results Different age-related gene classes have been modified by deletion or o…

Distinct Site Specificity of Two Pea Histone Deacetylase Complexes

2001

We report on the site specificity of two intact pea histone deacetylase complexes. HD1 deacetylates lysines 5 and 16 of H4 in the order K16 > K5, while in the case of H3 the preferred order is K4 >> K18 approximately K9. The specificity of the HD2 complex is markedly different. The preferred residues in H4 are K8 approximately K5 > K16, while in H3 deacetylation, the complex HD2 prefers sites 4 and 18. To obtain these results, we have used a novel procedure based on the SPOT technique, a method to synthesize peptides on membrane supports. Different sets of membranes with sequentially overlapping histone peptides containing acetylated lysines in the sites corresponding to all in vivo acetyla…

Genetic identification of a network of factors that functionally interact with the nucleosome remodeling ATPase ISWI.

2008

Nucleosome remodeling and covalent modifications of histones play fundamental roles in chromatin structure and function. However, much remains to be learned about how the action of ATP-dependent chromatin remodeling factors and histone-modifying enzymes is coordinated to modulate chromatin organization and transcription. The evolutionarily conserved ATP-dependent chromatin-remodeling factor ISWI plays essential roles in chromosome organization, DNA replication, and transcription regulation. To gain insight into regulation and mechanism of action of ISWI, we conducted an unbiased genetic screen to identify factors with which it interacts in vivo. We found that ISWI interacts with a network o…

In vivo GSH depletion induces c-myc expression by modulation of chromatin protein complexes.

2009

Abstract We hypothesize that glutathione (GSH) fluctuations could have a prominent role in the modulation of c-myc expression through a mechanism affecting chromatin remodeling complexes. This could lead to an open chromatin structure accessible to transcription factors. We studied the in vivo effect of GSH depletion on these complexes bound to the c-myc promoter in the liver of l-buthionine-(S,R)-sulfoximine (BSO)-treated rats. Using chromatin immunoprecipitation we found that 3 h after BSO treatment the repressing complexes Id2 and Sin3A (part of a histone–deacetylase complex) were released from the c-myc promoter. STAT3 was phosphorylated and associated with its coactivator p300 with int…

Dexamethasone upregulates Nox1 expression in vascular smooth muscle cells.

2014

&lt;b&gt;&lt;i&gt;Background/Aim:&lt;/i&gt;&lt;/b&gt; It has been demonstrated that dexamethasone-induced hypertension can be prevented by the NADPH oxidase inhibitor apocynin. The effect of dexamethasone on NADPH oxidase, however, is unknown. The present study was conducted to investigate the effect of dexamethasone on the gene expression of Nox1, the major NADPH oxidase isoform in vascular smooth muscle cells. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; Oral treatment of Wistar-Kyoto rats with dexamethasone (0.03 mg/kg/day) for 12 days led to an upregulation of Nox1 mRNA expression in the aorta. In cultured A7r5 rat aortic smooth muscle cells, dexamethasone increased Nox1 mRNA expressi…

Class IIa HDACs repressive activities on MEF2-depedent transcription are associated with poor prognosis of ER⁺ breast tumors.

2013

MEF2s transcription factors and class IIa HDACs compose a fundamental axis for several differentiation pathways. Functional relationships between this axis and cancer are largely unexplored. We have found that class IIa HDACs are heterogeneously expressed and display redundant activities in breast cancer cells. Applying gene set enrichment analysis to compare the expression profile of a list of putative MEF2 target genes, we have discovered a correlation between the down-regulation of the MEF2 signature and the aggressiveness of ER(+) breast tumors. Kaplan-Meier analysis in ER(+) breast tumors evidenced an association between increased class IIa HDACs expression and reduced survival. The im…

Deregulated repression of c-Jun provides a potential link to its role in tumorigenesis.

2004

The transcription factor c-Jun cooperates with oncogenic alleles of ras in malignant transformation. Constitutively active Ras causes, via activation of mitogen activated protein kinases, phosphorylation of c-Jun which is essential for subsequent target gene activation and tumorigenesis. Studying the mechanisms controlling c-Jun activity we found that its transcription activation function is actively repressed by a presumably multimeric repressor complex that includes histone deacetylase 3 as a critical subunit. Suppression of c-Jun is relieved by MAP kinase-mediated phosphorylation and/or titration of inhibitor components. The viral tumorigenic counterpart of c-Jun, v-Jun, escapes this inh…

Histone deacetylase A key enzyme for the binding of regulatory proteins to chromatin

1993

AbstractCore histones can be modified by reversible, posttranslational acetylation of specific lysine residues within the N-terminal protein domains. The dynamic equilibrium of acetylation is maintained by two enzyme activities, histone acetyltransferase and histone deacetylase. Recent data on histone deacetylases and on anionic motifs in chromatin- or DNA-binding regulatory proteins (e.g. transcription factors, nuclear proto-oncogenes) are summarized and united into a hypothesis which attributes a key function to histone deacetylation for the binding of regulatory proteins to chromatin by a transient, specific local increase of the positive charge in the N-terminal domains of nucleosomal c…

Redox signaling in acute pancreatitis

2015

Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On th…
