Cycloheximide
Antibiotic substance isolated from streptomycin-producing strains of Streptomyces griseus. It acts by inhibiting elongation during protein synthesis.
Protein Synthesis Inhibitors
Compounds which inhibit the synthesis of proteins. They are usually ANTI-BACTERIAL AGENTS or toxins. Mechanism of the action of inhibition includes the interruption of peptide-chain elongation, the blocking the A site of ribosomes, the misreading of the genetic code or the prevention of the attachment of oligosaccharide side chains to glycoproteins.
Dactinomycin
A compound composed of a two CYCLIC PEPTIDES attached to a phenoxazine that is derived from STREPTOMYCES parvullus. It binds to DNA and inhibits RNA synthesis (transcription), with chain elongation more sensitive than initiation, termination, or release. As a result of impaired mRNA production, protein synthesis also declines after dactinomycin therapy. (From AMA Drug Evaluations Annual, 1993, p2015)

RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Apoptosis
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

DNA
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

Bcl-2 and Bcl-XL serve an anti-inflammatory function in endothelial cells through inhibition of NF-kappaB. (1/5972)

To maintain the integrity of the vascular barrier, endothelial cells (EC) are resistant to cell death. The molecular basis of this resistance may be explained by the function of antiapoptotic genes such as bcl family members. Overexpression of Bcl-2 or Bcl-XL protects EC from tumor necrosis factor (TNF)-mediated apoptosis. In addition, Bcl-2 or Bcl-XL inhibits activation of NF-kappaB and thus upregulation of proinflammatory genes. Bcl-2-mediated inhibition of NF-kappaB in EC occurs upstream of IkappaBalpha degradation without affecting p65-mediated transactivation. Overexpression of bcl genes in EC does not affect other transcription factors. Using deletion mutants of Bcl-2, the NF-kappaB inhibitory function of Bcl-2 was mapped to bcl homology domains BH2 and BH4, whereas all BH domains were required for the antiapoptotic function. These data suggest that Bcl-2 and Bcl-XL belong to a cytoprotective response that counteracts proapoptotic and proinflammatory insults and restores the physiological anti-inflammatory phenotype to the EC. By inhibiting NF-kappaB without sensitizing the cells (as with IkappaBalpha) to TNF-mediated apoptosis, Bcl-2 and Bcl-XL are prime candidates for genetic engineering of EC in pathological conditions where EC loss and unfettered activation are undesirable.  (+info)

NMD3 encodes an essential cytoplasmic protein required for stable 60S ribosomal subunits in Saccharomyces cerevisiae. (2/5972)

A mutation in NMD3 was found to be lethal in the absence of XRN1, which encodes the major cytoplasmic exoribonuclease responsible for mRNA turnover. Molecular genetic analysis of NMD3 revealed that it is an essential gene required for stable 60S ribosomal subunits. Cells bearing a temperature-sensitive allele of NMD3 had decreased levels of 60S subunits at the nonpermissive temperature which resulted in the formation of half-mer polysomes. Pulse-chase analysis of rRNA biogenesis indicated that 25S rRNA was made and processed with kinetics similar to wild-type kinetics. However, the mature RNA was rapidly degraded, with a half-life of 4 min. Nmd3p fractionated as a cytoplasmic protein and sedimented in the position of free 60S subunits in sucrose gradients. These results suggest that Nmd3p is a cytoplasmic factor required for a late cytoplasmic assembly step of the 60S subunit but is not a ribosomal protein. Putative orthologs of Nmd3p exist in Drosophila, in nematodes, and in archaebacteria but not in eubacteria. The Nmd3 protein sequence does not contain readily recognizable motifs of known function. However, these proteins all have an amino-terminal domain containing four repeats of Cx2C, reminiscent of zinc-binding proteins, implicated in nucleic acid binding or protein oligomerization.  (+info)

delta-Aminolevulinate synthetases in the liver cytosol fraction and mitochondria of mice treated with allylisopropylacetamide and 3,5-dicarbethoxyl-1,4-dihydrocollidine. (3/5972)

Hepatic delta-aminolevulinate (ALA) synthetase was induced in mice by the administration of allylisopropylacetamide (AIA) and 3,5-dicarbethoxy-1,4-dihydrocollidine (DDC). In both cases, a significant amount of ALA synthetase accumulated in the liver cytosol fraction as well as in the mitochondria. The apparent molecular weight of the cytosol ALA synthetase was estimated to be 320,000 by gel filtration, but when the cytosol ALA synthetase was subjected to sucrose density gradient centrifugation, it showed a molecular weight of 110,000. In the mitochondria, there were two different sizes of ALA synthetase with molecular weights of 150,000 and 110,000, respectively; the larger enzyme was predominant in DDC-treated mice, whereas in AIA-treated mice and normal mice the enzyme existed mostly in the smaller form. When hemin was injected into mice pretreated with DDC, the molecular size of the mitochondrial ALA synthetase changed from 150,000 to 110,000. The half-life of ALA synthetase in the liver cytosol fraction was about 30 min in both the AIA-treated and DDC-treated mice. The half-life of the mitochondrial ALA synthetase in AIA-treated mice and normal mice was about 60 min, but in DDC-treated mice the half-life was as long as 150 min. The data suggest that the cytosol ALA synthetase of mouse liver is a protein complex with properties very similar to those of the cytosol ALA synthetase of rat liver, which has been shown to be composed of the enzyme active protein and two catalytically inactive binding proteins, and that ALA synthetase may be transferred from the liver cytosol fraction to the mitochondria with a size of about 150,000 daltons, followed by its conversion to enzyme with a molecular weight of 110,000 within the mitochondria. The process of intramitochondrial enzyme degradation seems to be affected in DDC-treated animals.  (+info)

Microvessels from Alzheimer's disease brains kill neurons in vitro. (4/5972)

Understanding the pathogenesis of Alzheimer's disease is of widespread interest because it is an increasingly prevalent disorder that is progressive, fatal, and currently untreatable. The dementia of Alzheimer's disease is caused by neuronal cell death. We demonstrate for the first time that blood vessels isolated from the brains of Alzheimer's disease patients can directly kill neurons in vitro. Either direct co-culture of Alzheimer's disease microvessels with neurons or incubation of cultured neurons with conditioned medium from microvessels results in neuronal cell death. In contrast, vessels from elderly nondemented donors are significantly (P<0.001) less lethal and brain vessels from younger donors are not neurotoxic. Neuronal killing by either direct co-culture with Alzheimer's disease microvessels or conditioned medium is dose- and time-dependent. Neuronal death can occur by either apoptotic or necrotic mechanisms. The microvessel factor is neurospecific, killing primary cortical neurons, cerebellar granule neurons, and differentiated PC-12 cells, but not non-neuronal cell types or undifferentiated PC-12 cells. Appearance of the neurotoxic factor is decreased by blocking microvessel protein synthesis with cycloheximide. The neurotoxic factor is soluble and likely a protein, because its activity is heat labile and trypsin sensitive. These findings implicate a novel mechanism of vascular-mediated neuronal cell death in Alzheimer's disease.  (+info)

Expression of thrombospondin-1 in ischemia-induced retinal neovascularization. (5/5972)

Thrombospondin-1 is an extracellular matrix protein that inhibits endothelial cell proliferation, migration, and angiogenesis. This study was performed to investigate the role of thrombospondin-1 in ischemic retinal neovascularization. In a murine model of retinal neovascularization, thrombospondin-1 mRNA was increased from postnatal day 13 (P13), with a threefold peak response observed on P15, corresponding to the time of development of retinal neovascularization. Prominent expression of thrombospondin-1 was observed in neovascular cells, specifically, cells adjacent to the area of nonperfusion. It has been suggested that vascular endothelial growth factor (VEGF) plays a major role in ischemia-induced retinal neovascularization of this model, so we studied the effects of VEGF on thrombospondin-1 expression. In bovine retinal microcapillary endothelial cells, VEGF induced a biphasic response of thrombospondin-1 expression; VEGF decreased thrombospondin-1 mRNA 0.41-fold after 4 hours, whereas it increased, with a threefold peak response, after 24 hours. VEGF-induced endothelial cell proliferation was completely inhibited by exogenous thrombospondin-1 and increased by 37.5% with anti-thrombospondin-1 antibody. The present findings suggest that, in the ischemic retina, retinal neovascular cells increase thrombospondin-1 expression, and VEGF may stimulate endogenous thrombospondin-1 induction, which inhibits endothelial cell growth. VEGF-mediated thrombospondin-1 induction in ischemia-induced angiogenesis may be a negative feedback mechanism.  (+info)

5'-Nucleotidase activity of mouse peritoneal macrophages. II. Cellular distribution and effects of endocytosis. (6/5972)

The diazonium salt of sulfanilic acid (DASA) can inactivate about 80% of the total 5'-nucleotidase of viable macrophages. The remaining 20% can be inactivated if the cells are first lysed in detergent, and presumably represents an intracellular pool of 5'-nucleotidase. The bulk of this pool may represent cytoplasmic vesicles derived from plasma membrane by endocytosis. This internal compartment is expanded up to threefold immediately after the cells have ingested a large latex load. This is consistent with previous observations on the internalization of 5'-nucleotidase in latex phagosomes. In latex-filled cells this intracellular pool of enzyme is inactivated over a few hours, and the cells then slowly increase their enzyme activity to nearly normal levels. However, 24 h after latex ingestion the metabolism of 5'-nucleotidase in these recovered cells is abnormal, as the rate of enzyme degradation is about twice the normal rate, and the DASA-insensitive enzyme pool in these cells is strikingly diminished. This may reflect effects of the accumulated indigestible particles on the fate of incoming pinocytic vesicles or on newly synthesized plasma membrane precursor. Another endocytic stimulus, concanavalin A, also reduces the total cell 5'-nucleotidase activity. This effect, which is time and temperature dependent, can be prevented by the competitive sugar alpha-methyl mannose. The concanavalin A inhibition can be reversed in the absence of new protein synthesis or in cells cultivated in serum-free conditions. It is not known whether the effect of concanavalin A on 5'-nucleotidase depends upon the interiorizaiton of plasma membrane or is strictly associated with events at the cell surface.  (+info)

CFTR channel insertion to the apical surface in rat duodenal villus epithelial cells is upregulated by VIP in vivo. (7/5972)

cAMP activated insertion of the cystic fibrosis transmembrane conductance regulator (CFTR) channels from endosomes to the apical plasma membrane has been hypothesized to regulate surface expression and CFTR function although the physiologic relevance of this remains unclear. We previously identified a subpopulation of small intestinal villus epithelial cells or CFTR high expressor (CHE) cells possessing very high levels of apical membrane CFTR in association with a prominent subapical vesicular pool of CFTR. We have examined the subcellular redistribution of CFTR in duodenal CHE cells in vivo in response to the cAMP activated secretagogue vasoactive intestinal peptide (VIP). Using anti-CFTR antibodies against the C terminus of rodent CFTR and indirect immunofluorescence, we show by quantitative confocal microscopy that CFTR rapidly redistributes from the cytoplasm to the apical surface upon cAMP stimulation by VIP and returns to the cytoplasm upon removal of VIP stimulation of intracellular cAMP levels. Using ultrastructural and confocal immunofluorescence examination in the presence or absence of cycloheximide, we also show that redistribution was not dependent on new protein synthesis, changes in endocytosis, or rearrangement of the apical cytoskeleton. These observations suggest that physiologic cAMP activated apical membrane insertion and recycling of CFTR channels in normal CFTR expressing epithelia contributes to the in vivo regulation of CFTR mediated anion transport.  (+info)

Expression of atrC - encoding a novel member of the ATP binding cassette transporter family in Aspergillus nidulans - is sensitive to cycloheximide. (8/5972)

A new member of the ABC superfamily of transmembrane proteins in Aspergillus nidulans has been cloned and characterized. The topology of conserved motifs subgroups AtrC in the P-glycoprotein cluster of ABC permeases, the members of this subfamily, are known to participate in multidrug resistance (MDR) in diverse organisms. Alignment results display significant amino acid similarity to AfuMDR1 and AflMDR1 from Aspergillus fumigatus and flavus, respectively. Northern analysis reveals that atrC mRNA levels are 10-fold increased in response to cycloheximide. Evidence for the existence of eight additional hitherto unpublished ABC transporter proteins in A. nidulans is provided.  (+info)

The effects of anisomycin (a protein synthesis inhibitor) on spatial learning and memory in CA1 region of rats hippocampusThe effects of anisomycin (a protein synthesis inhibitor) on spatial learning and memory in CA1 region of rats hippocampus
Studies were performed to investigate whether electrically-induced long-term depression (LTD) within rat hippocampal slices in vitro shares any common cellular features with LTD in the intact animal, with particular emphasis being placed on mechanisms required for its late maintenance. Our initial studies have led to the development of stimulation protocols which are able to reliably produce different forms of LTD. Depending on the induction protocol applied, we are able to demonstrate a transient protein synthesis-independent early-LTD with a duration of up to 3-4 h, together with a de novo protein synthesis-dependent late-LTD lasting for at least 8 h. Furthermore, we are able to show input-specific LTD within the CA1 region, with expression shown only by those synapses specifically stimulated by a low-frequency protocol. These studies are important pre-requisites to investigate mechanisms of synaptic tagging and late-associativity during LTD ...

HTLV receptor is an early T-cell activation marker whose expression requires de novo protein synthesis | Blood | American...HTLV receptor is an early T-cell activation marker whose expression requires de novo protein synthesis | Blood | American...
Expression of the HTLV receptor was strictly dependent on de novo protein synthesis. It has been shown that prior to T-lymphocyte proliferation, there is a 7- to 10-fold increase in protein synthesis and a 30- to 40-fold augmentation in mRNA synthesis.33This pre-proliferation characteristic appears to be a particularity of T lymphocytes and is not observed in other cell types. The required pre-proliferation burst in mRNA/protein synthesis likely results from the extremely low metabolic rate of resting G0T lymphocytes, which make up the vast majority of the circulating T-lymphocyte pool. Thus, it is intriguing to speculate that it is this low metabolic rate that accounts for the fact that T lymphocytes are the first and only cell type, identified to date, which do not constitutively express the HTLV receptor. Notably, Wodarz and Bangham have recently used a mathematical model to suggest that the rate of evolution of HTLV-1 is limited by the restricted availability of activated uninfected T ...

We have investigated the effect of chemotherapeutic and DNA damaging agents on binding of the tumor suppressor phosphoprotein p53 to its consensus DNA sequence. Activation of p53-DNA binding was seen for treatment with radiation, hydrogen peroxide, actinomycin D, Adriamycin, etoposide, camptothecin, 5-fluorouracil, mitomycin C, and cisplatin. These results showed that DNA strand breaks were sufficient to lead to increased levels of p53. The protein synthesis inhibitor cycloheximide blocks the increase in p53 following DNA damage. The increase in p53 activation in camptothecin treated cells may result, at least in part, from an increased half-life of the protein and consequent increases in intracellular protein concentration.. ...

Cycloheximide-induced activation of mouse eggs: effects on cdc2/cyclin B and MAP kinase activities | Journal of Cell ScienceCycloheximide-induced activation of mouse eggs: effects on cdc2/cyclin B and MAP kinase activities | Journal of Cell Science
Fertilization of metaphase II-arrested mouse eggs results in resumption of meiosis and a decrease in both cdc2/cyclin B kinase and MAP kinase activities; the decrease in cdc2/cyclin B kinase activity precedes the decrease in MAP kinase activity. Cycloheximide treatment of metaphase II-arrested mouse eggs also results in resumption of meiosis but bypasses the fertilization-induced Ca2+ transient. However, it is not known if cycloheximide treatment results in the same temporal changes in cdc2/cyclin B kinase and MAP kinase activities that are intimately associated with resumption of meiosis. We report that cycloheximide-treated mouse eggs manifest similar temporal changes in the decrease in both cdc2/cyclin B kinase and MAP kinase activities that occur following fertilization, although cortical granule exocytosis is not stimulated. The decrease in cdc2/cyclin B kinase activity, however, does not seem to be required for the decrease in MAP kinase activity, since the decrease in MAP kinase activity ...

Fig. 5. Identification of Pax3 binding sites on Pax3 promoters in vitro (A) Pax3, but not Zic1 alone, can trigger synthesis of the endogenous Pax3 transcript (primers in 3UTR, not amplifying the inducible form) either in absence of the translation inhibitor cycloheximide (induction is 5-fold compared to uninjected animal caps) or in the presence of cycloheximide (induction is 31-fold, compared to cycloheximide-treated uninjected animal caps). Endogenous pax3 expression level in a stage 11 whole embryo is set at a relative value of 1 unit. After co-injection of Pax3 and Zic1, endogenous pax3 was activated as an immediate-early target as well (77-fold compared to uninjected animal caps; and, in presence of cycloheximide, 16-fold when compared to cycloheximide-treated uninjected animal caps).

In DG cultures exposed to 10 mM NaCN for 45 min, ≈90% of neurons (identified by immunoreactivity against NeuN, a neuronal marker) died 24 h after hypoxia, because they stained with propidium iodide. Survival of GFAP-immunoreactive glia was not affected (data not shown). Combining the same cyanide treatment with glucose deprivation (ischemia) had very similar effects on the neurons. By EM, many hypoxic neurons showed early swelling of mitochondria and endoplasmic reticulum, in the presence of an intact nucleus (Fig. 1B), and evolved later toward necrosis with severe cytoplasmic swelling and membrane rupture (Fig. 1C). This finding was in sharp contrast to staurosporine-treated apoptotic neurons, which displayed nuclear breakdown into large, round masses of chromatin (Fig. 1D). Hypoxic necrosis evolved rapidly: we observed a progressive loss of the mitochondrial membrane potential Δψ within a few minutes of cyanide application (Fig. 2 A-D). This Δψ decay was always synchronous with release ...

Gonadotrophin-releasing activity of oxytocin has previously been demonstrated in vitro and in vivo. This study investigated whether oxytocin is also able to induce LH accumulation in pituitary cells. Following trypsin digestion and mechanical dispersion, pituitary cells from female rats were incubated with oxytocin (100 nmol/l) for 24 h. LH release stimulated by oxytocin increased (P , 0·001) progressively during the incubation indicating a different secretory pattern from the more rapid but less sustained secretion stimulated by gonadotrophin-releasing hormone. Oxytocin also enhanced (P , 0·01) total LH accumulation in the incubation system (released plus cell contents) which was apparent after 7-11 h of stimulation. The release of LH stimulated by oxytocin was reduced by the protein synthesis inhibitor cycloheximide (10 μmol/l). However, cycloheximide did not completely block oxytocin-stimulated LH release; there remained some LH release above that seen in non-stimulated controls (P , ...

Treatment with the protein synthesis inhibitor cycloheximide (CHX) or silencing of the core component of the NMD machinery, Upf-1 (also known as Rent1), are widely used to determine if transcripts are subject to NMD (Montfort et al., 2006). CHX is an indirect NMD inhibitor since NMD activation is posttranscriptional, but translation-dependent, and ribosomal association is required during the pioneer round of translation. Upf-1 silencing is believed to produce direct suppression of NMD. The RNA helicase, Upf-1, is a central effector of NMD that links the translation-termination event to the assembly of a surveillance complex. Upf2 and Upf3 are believed to recruit and activate Upf1 on NMD substrates (Lykke-Andersen et al., 2000). Although the discrimination of PTCs from normal termination codons and the molecular links that trigger NMD are still unclear, it is well established that the core components of the NMD machinery are the conserved proteins, Upf-1, Upf-2 and Upf-3. PTC-containing mRNAs ...

When cultivated on substrates that prevent cell adhesion (the polymer polyhydroxyethylmethacrylate, bovine serum albumin, and Teflon), human endothelial cells (EC) rapidly lost viability with a half-life of approximately 10 h. Dying EC showed the morphological and biochemical characteristics of apoptosis. The apoptotic process of suspended EC was delayed by the protein synthesis inhibitor cycloheximide. To obtain information as to the mechanism involved in the apoptosis of suspended EC, we investigated whether adhesion to matrix proteins or integrin occupancy in EC retaining a round shape may affect EC suicide. EC bound to low coating concentration of either fibronectin or vitronectin, retaining a round shape and failing to organize actin microfilaments, underwent to rapid cell death; by contrast, cells on high substrate concentrations became flattened, showed actin microfilament organization, and retained viability.

TNFα, the founding member of the TNF-superfamily, mediates both necroptotic and apoptotic cell death (Walczak, 2011; Micheau and Tschopp, 2003; Andrew, 2004; Wang et al., 2008; Kroemer et al., 2007; Degterev and Yuan, 2008, He et al., 2009; Zhang et al., 2009). Although many investigations have been conducted over the last few years the detailed mechanisms of these death signaling pathways are still not completely known. This particularly concerns our understanding about where ROS are produced intracellularly, how ROS and LMP are mechanistically linked and how both processes contribute to TNFα-induced apoptosis (Boya and Kroemer, 2008; Shen and Pervaiz, 2006; Zdolsek et al., 1993; Brunk et al., 1995). Our study here bridges these missing gaps. We identified that TNFα/CHX-induced LMP is not an apoptosis initiating, but amplifying process downstream of MOMP, and it is triggered by mitochondrial ROS generated as the result of a caspase-3-mediated cleavage of the p75 NDUFS1 subunit of complex I. ...

A single hyperthermic exposure can render cells transiently resistant to subsequent high temperature stresses. Treatment of rat embryonic fibroblasts with cycloheximide for 6 h after a 20-min interval at 45 degrees C inhibits protein synthesis, including heat shock protein (hsp) synthesis, and results in an accumulation of hsp 70 mRNA, but has no effect on subsequent survival responses to 45 degrees C hyperthermia. hsp 70 mRNA levels decreased within 1 h after removal of cycloheximide but then appeared to stabilize during the next 2 h (3 h after drug removal and 9 h after heat shock). hsp 70 mRNA accumulation could be further increased by a second heat shock at 45 degrees C for 20 min 6 h after the first hyperthermic exposure in cycloheximide-treated cells. Both normal protein and hsp synthesis appeared increased during the 6-h interval after hyperthermia in cultures which received two exposures to 45 degrees C for 20 min compared with those which received only one treatment.

106. Abstract Protoplasts of Boergesenia forbesii (Hanvey) were treated with inhibitors of protein synthesis in order to investigate their effects on cellulose synthesis. Cellulose synthesis was reversibly inhibited by 10 M cycloheximide as assayed by fluorescence microscopy of Tinopal binding to cellulose. Freeze fracture and image analysis of cycloheximide-treated cells indicated a reduction in the number of intramembrane particles; however, the terminal synthesizing complexes remained at all times. Treatment with 10 M actinomycin D, when applied during the first hour of protoplast formation, irreversibly inhibits cellulose synthesis and terminal complex formation. De novo protein synthesis is required for cell wall regeneration by protoplasts. The data suggest that the structural subunits visualized in the terminal complex do not undergo signifi-cant turnover, but that there may exist an essential proteinaceous component of cellulose synthesis which must be continually renewed ...

Cycloheximide - WikipediaCycloheximide - Wikipedia
Cycloheximide is a eukaryote protein synthesis inhibitor, produced by the bacterium Streptomyces griseus. Cycloheximide exerts its effect by interfering with the translocation step in protein synthesis (movement of two tRNA molecules and mRNA in relation to the ribosome), thus blocking translational elongation. Cycloheximide is widely used in biomedical research to inhibit protein synthesis in eukaryotic cells studied in vitro (i.e. outside of organisms). It is inexpensive and works rapidly. Its effects are rapidly reversed by simply removing it from the culture medium.[1] Due to significant toxic side effects, including DNA damage, teratogenesis, and other reproductive effects (including birth defects and toxicity to sperm[2]), cycloheximide is generally used only in in vitro research applications, and is not suitable for human use as a therapeutic compound. Although it has been used as a fungicide in agricultural applications, this application is now decreasing as the health risks have become ...

Memory can be divided according to different temporal phases: acquisition, consolidation, and retrieval. The consolidation phase is divided into molecular consolidation (range of hours after acquisition) and system consolidation (range of weeks and months after acquisition) (Dudai, 2004). Molecular consolidation is thought to be a protein synthesis-dependent process (Alberini, 2008; Costa-Mattioli et al., 2009). The clear effect of protein synthesis inhibitors on long-term memory was studied extensively mainly in the context of late-phase long-term potentiation (LTP) (Abraham and Williams, 2008). Similar molecular mechanisms were proposed for maintenance of long-term synaptic modifications and learning processes (Davis and Squire, 1984; Costa-Mattioli et al., 2009). However, long-term memory is not supported only by modulation of synaptic strength; modifications in intrinsic neuronal properties also subserve learning-related behavioral changes (Saar and Barkai, 2003; Zhang and Linden, 2003; ...

The Effect of Cycloheximide on the Replication of Measles Virus | Microbiology SocietyThe Effect of Cycloheximide on the Replication of Measles Virus | Microbiology Society
Summary Treatment of measles virus-infected cells with cycloheximide results in a three-fold increase of 3H-uridine incorporation into the 12 to 36S mRNA species and in the inhibition of genomic 50S RNA synthesis. Consistent with these observations was the finding of a build-up of polyribosomes but an absence of nucleocapsids in the infected cells. These results suggest that measles virus RNA replication, but not transcription, is dependent upon active protein synthesis.

This conclusion was supported by studies of IκBα protein turnover in the DLBCL cell lines. Because IκBα transcription is itself positively regulated by NF-κB activity (37, 38), the steady-state level of IκBα protein does not necessarily reflect the rate of phosphorylation by IKK and subsequent degradation. Indeed, full-length IκBα protein is found at comparable levels in our untreated cell lines (Fig. 3 A). However, when ABC DLBCL cell lines were treated with cycloheximide (CHX) to block new protein synthesis, the level of IκBα declined rapidly through phosphorylation and degradation (Fig. 3 A). By contrast, the IκBα level in SUDHL-6 was significantly more stable upon CHX treatment unless the cells were also stimulated by BCR cross-linking or by PMA and ionomycin treatment (Fig. 3 A). Lactacystin, a drug that inhibits degradation of ubiquitinated IκBα by proteasomes, prevented the CHX-induced loss of IκBα in resting ABC DLBCL cell lines and in stimulated SUDHL-6 cells (Fig. 3 ...

Reminiscent of GREs and negative GREs (nGREs), a delayed sGRE confers hormonal regulation upon a linked heterologous promoter from a downstream position with respect to transcription start site and, remarkably, also interacts selectively with ...

SR9243 is a potent and selective LXR inverse agonist. SR9243 kills cancer cells by inhibiting lipid production and the Warburg effect. SR9243 induces cell death in multiple types of cancer and does not cause the side effects that have derailed previous attempts to target these processes. In cancer cells, SR9243 significantly inhibited the Warburg effect and lipogenesis by reducing glycolytic and lipogenic gene expression. SR9243 induced apoptosis in tumors without inducing weight loss, hepatotoxicity, or inflammation. Malignant cells exhibit aerobic glycolysis (the Warburg effect) and become dependent on de novo lipogenesis, which sustains rapid proliferation and resistance to cellular stress.

N-methyl-D-aspartate receptor-mediated neuroprotection in cerebellar granule cells requires new RNA and protein synthesis | PNASN-methyl-D-aspartate receptor-mediated neuroprotection in cerebellar granule cells requires new RNA and protein synthesis | PNAS
Cerebellar granule cells are susceptible to the excitotoxin glutamate, which acts at N-methyl-D-aspartate (NMDA) receptors, as well as the neurotoxin 1-methyl-4-phenylpyridinium ion (MPP+), the active cytotoxic metabolite of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Paradoxically, preincubation of cultured cerebellar granule cells with low concentrations of NMDA or glutamate markedly antagonizes the neurotoxicity resulting from subsequent exposure to toxic concentrations of either MPP+ or glutamate. The neuroprotective effects of NMDA and glutamate against MPP+ toxicity are observed at agonist concentrations as low as 1 microM, are blocked by specific NMDA receptor antagonists, and require at least 30 min to develop fully. Moreover, NMDA receptor-mediated neuroprotection is prevented by the RNA synthesis inhibitor actinomycin D or the protein synthesis inhibitor cycloheximide. Thus, in cerebellar granule cells activation of NMDA receptors by glutamate can result in either ...

The prolactin receptor (PRLR) mediates the diverse effects of prolactin, which in the mammary gland include the development of lobuloalveolar structures and increased tumor cell proliferation. Treatment of mammary carcinoma cells with the differentiating agent sodium butyrate (NaB) is known to reduce PRLR binding activity and PRLR gene expression, however the mechanism which mediates these changes is unknown, prompting this investigation. Using MCF-7 human breast cancer cells, assay of the rate of PRLR gene transcription by the nuclear run-on technique indicated that 3 mM NaB reduced PRLR gene transcription by 50% after 3 h of treatment and that this effect was maintained for at least 24 h. The protein synthesis inhibitor cycloheximide failed to abrogate this effect, which indicated that NaB did not require continuing protein synthesis to reduce the rate of PRLR transcription.

Two lipid synthesis inhibitors compounds (spiromesifen SPM and spirotetramat SPT) were used against the second instar larvae of cotton leaf worm, Spodoptera littoralis under laboratory condition. Toxicity of both compounds was tested. Effect of these insecticides on total lipid also was determined. The obtained results showed that both compounds were moderately toxic against the second instar larvae of S. littoralis. The mortality percentages caused by the field rate of spiromesifen and spirotetramat were 51.7 and 60.0%, respectively. The lethal concentrations for 50% of tested insect population (LC50) were 170.1 and 42.2 ppm, respectively. The total lipid content was determined in treated larvae and compared with the untreated. The percentage of total lipid in spiromesifen- and spirotetramat-treated larvae was 2.17 and 2.21%, respectively, compared with 2.42% in untreated larvae.

Apoptosis induced by mild hyperthermia in human and murine tumour cell lines: A study using electron microscopy and DNA gel...Apoptosis induced by mild hyperthermia in human and murine tumour cell lines: A study using electron microscopy and DNA gel...
Mild hyperthermia is known to enhance apoptosis in a range of normal and neoplastic cell populations. Studies of tumours previously shown to respond to heating in this manner might be expected to provide insights not only into the mechanism of hyperthermic cell killing, but also into the apoptotic process in general. In the present study, cell death induced by 43°C heating for 30 min in two human Burkitts lymphoma lines, BM 13674 and WW1, and in murine mastocytoma P‐815 × 2·1 was found to be exclusively apoptotic in type, identification being based on light and electron microscopic appearances and on the presence of internucleosomal cleavage of DNA into fragments that are multiples of 180-200 base pairs, which was demonstrated by agarose gel electrophoresis. The heat‐induced apoptosis was prevented by the presence of zinc sulphate, an inhibitor of the endonuclease considered to be responsible for the DNA cleavage, but was not suppressed by the protein synthesis inhibitor cycloheximide. ...

An in vitro ischemia model was established and the effect of the metabolic inhibitors cycloheximide (CHX) and actinomycin D (ActD) on apoptosis in astrocytes under ischemia studied. CHX decreased by 75% the number of cells dying after 6 hr of ischemia compared with control cultures. TdT-mediated dUTP nick end labelling (TUNEL) staining of comparable cultures was reduced by 40%. ActD decreased cell death by 60% compared with controls. The number of TUNEL-positive cells was reduced by 38%. The nuclear shrinkage in TUNEL-positive astrocytes in control cultures did not occur in ActD-treated astrocytes, indicating that nuclear shrinkage and DNA fragmentation during apoptosis are two unrelated processes. Expression of bcl-2 (alpha and beta), bax, and Ice in astrocytes under similar ischemic conditions, as measured by quantitative reverse transcription-polymerase chain reaction, indicated that ischemia down-regulated bcl-2 (alpha and beta) and bax. Ice was initially down-regulated from 0 to 4 hr, ...

kbrin.a-bldg.louisville.edukbrin.a-bldg.louisville.edu
We used the rat visual cortex as a model system to examine the changes in protein synthesis during experience-induced synaptic plasticity. Dark-rearing rats from birth results in a relatively immature visual cortex that maintains the high de- gree of synaptic plasticity characteristic of the critical period (Kirkwood et al., 1995). Exposure of dark-reared rats to light results in a rapid, robust and coordinated burst of experience- driven synaptic plasticity that can be readily monitored at the biochemical and electrophysiological level (Quinlan et al., 1999). In previous work, we showed that visual experience evokes the polyadenylation of ␣-CaMKII mRNA in visual cortex and the elevation of ␣-CaMKII protein in synaptic fractions from this brain region. Moreover, this increase was a direct result of new synthesis because it was sensitive to the translation inhibitor cycloheximide (Wu et al., 1998). Here we show that the experience-induced increase of ␣-CaMKII pro- tein does not require new ...

Despite intensive analysis zero therapies targeted contrary to the oncogenic EGFRvIII can be found in the medical clinic. PTP inhibitors triggered a prominent upsurge in phosphorylation degrees of EGFRvIII on all residues analyzed, including Tyr1045. Oddly enough, hypophosphorylation of the tyrosine continues to be previously reported on several occasions and from the raised stability from the proteins [7, 8]. Certainly, we have not really noticed any degradation from the truncated receptor also in the current presence of cycloheximide to avoid de novo proteins synthesis (Supplementary Amount 2). Statistical evaluation indicated which the change in phosphorylation of specific tyrosines had not been always significant in case there is the wild-type receptor, that will be due to a combined mix of limited awareness of the technique and a comparatively few reproductions (= 3). To check this hypothesis, weve centered on NaOVa, a much less powerful PTP inhibitor of both, and examined its influence on ...
