In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.

The interaction of rhodium(II) carboxylates with enzymes. (1/39504)

The effect of rhodium(II) acetate, propionate, and methoxyacetate on the activity of 17 enzymes was evaluated. The enzymes were preincubated with the rhodium(II) complexes in order to detect irreversible inhibition. All enzymes that have essential sulfhydryl groups in or near their active site were found to be irreversibly inhibited. Those enzymes without essential sulfhydryl groups were not affected. In each case, the rate of inactivation closely paralleled the observed toxicity and antitumor activity of rhodium(II) carboxylates; that is, rhodium(II) propionate greater than rhodium(II) acetate greater than rhodium(II) methoxyacetate. In addition, those enzymes that have been demonstrated to be most sensitive to established sulfhydryl inhibitors, such as glyceraldehyde-3-phosphate dehydrogenase, were also most sensitive to rhodium(II) carboxylate inactivation. Proton nuclear magnetic resonance measurements made during the titration of rhodium(II) acetate with cysteine showed that breakdown of the carboxylate cage occurred as a result of reaction with this sulfhydryl-containing amino acid.  (+info)

Does gill boundary layer carbonic anhydrase contribute to carbon dioxide excretion: a comparison between dogfish (Squalus acanthias) and rainbow trout (Oncorhynchus mykiss). (2/39504)

In vivo experiments were conducted on spiny dogfish (Squalus acanthias) and rainbow trout (Oncorhynchus mykiss) in sea water to determine the potential role of externally oriented or gill boundary layer carbonic anhydrase in carbon dioxide excretion. This was accomplished by assessing pH changes in expired water using a stopped-flow apparatus. In dogfish, expired water was in acid-base disequilibrium as indicated by a pronounced acidification (delta pH=-0.11+/-0.01; N=22; mean +/- s.e.m.) during the period of stopped flow; inspired water, however, was in acid-base equilibrium (delta pH=-0.002+/-0.01; N=22). The acid-base disequilibrium in expired water was abolished (delta pH=-0.005+/-0.01; N=6) by the addition of bovine carbonic anhydrase (5 mg l-1) to the external medium. Addition of the carbonic anhydrase inhibitor acetazolamide (1 mmol l-1) to the water significantly reduced the magnitude of the pH disequilibrium (from -0.133+/-0.03 to -0.063+/-0.02; N=4). However, after correcting for the increased buffering capacity of the water caused by acetazolamide, the acid-base disequilibrium during stopped flow was unaffected by this treatment (control delta [H+]=99.8+/-22.8 micromol l-1; acetazolamide delta [H+]=81.3+/-21.5 micromol l-1). In rainbow trout, expired water displayed an acid-base disequilibrium (delta pH=0.09+/-0.01; N=6) that also was abolished by the application of external carbonic anhydrase (delta pH=0.02+/-0.01). The origin of the expired water acid-base disequilibrium was investigated further in dogfish. Intravascular injection of acetazolamide (40 mg kg-1) to inhibit internal carbonic anhydrase activity non-specifically and thus CO2 excretion significantly diminished the extent of the expired water disequilibrium pH after 30 min (from -0.123+/-0.01 to -0.065+/-0.01; N=6). Selective inhibition of extracellular carbonic anhydrase activity using a low intravascular dose (1.3 mg kg-1) of the inhibitor benzolamide caused a significant reduction in the acid-base disequilibrium after 5 min (from -0.11+/-0.01 to -0.07+/-0. 01; N=14). These results demonstrate that the expired water acid-base disequilibrium originates, at least in part, from excretory CO2 and that extracellular carbonic anhydrase in dogfish may have a significant role in carbon dioxide excretion. However, externally oriented carbonic anhydrase (if present in dogfish) plays no role in catalysing the hydration of the excretory CO2 in water flowing over the gills and thus is unlikely to facilitate CO2 excretion.  (+info)

A cytomegalovirus glycoprotein re-routes MHC class I complexes to lysosomes for degradation. (3/39504)

Mouse cytomegalovirus (MCMV) early gene expression interferes with the major histocompatibility complex class I (MHC class I) pathway of antigen presentation. Here we identify a 48 kDa type I transmembrane glycoprotein encoded by the MCMV early gene m06, which tightly binds to properly folded beta2-microglobulin (beta2m)-associated MHC class I molecules in the endoplasmic reticulum (ER). This association is mediated by the lumenal/transmembrane part of the protein. gp48-MHC class I complexes are transported out of the ER, pass the Golgi, but instead of being expressed on the cell surface, they are redirected to the endocytic route and rapidly degraded in a Lamp-1(+) compartment. As a result, m06-expressing cells are impaired in presenting antigenic peptides to CD8(+) T cells. The cytoplasmic tail of gp48 contains two di-leucine motifs. Mutation of the membrane-proximal di-leucine motif of gp48 restored surface expression of MHC class I, while mutation of the distal one had no effect. The results establish a novel viral mechanism for downregulation of MHC class I molecules by directly binding surface-destined MHC complexes and exploiting the cellular di-leucine sorting machinery for lysosomal degradation.  (+info)

p50(cdc37) acting in concert with Hsp90 is required for Raf-1 function. (4/39504)

Genetic screens in Drosophila have identified p50(cdc37) to be an essential component of the sevenless receptor/mitogen-activated kinase protein (MAPK) signaling pathway, but neither the function nor the target of p50(cdc37) in this pathway has been defined. In this study, we examined the role of p50(cdc37) and its Hsp90 chaperone partner in Raf/Mek/MAPK signaling biochemically. We found that coexpression of wild-type p50(cdc37) with Raf-1 resulted in robust and dose-dependent activation of Raf-1 in Sf9 cells. In addition, p50(cdc37) greatly potentiated v-Src-mediated Raf-1 activation. Moreover, we found that p50(cdc37) is the primary determinant of Hsp90 recruitment to Raf-1. Overexpression of a p50(cdc37) mutant which is unable to recruit Hsp90 into the Raf-1 complex inhibited Raf-1 and MAPK activation by growth factors. Similarly, pretreatment with geldanamycin (GA), an Hsp90-specific inhibitor, prevented both the association of Raf-1 with the p50(cdc37)-Hsp90 heterodimer and Raf-1 kinase activation by serum. Activation of Raf-1 via baculovirus coexpression with oncogenic Src or Ras in Sf9 cells was also strongly inhibited by dominant negative p50(cdc37) or by GA. Thus, formation of a ternary Raf-1-p50(cdc37)-Hsp90 complex is crucial for Raf-1 activity and MAPK pathway signaling. These results provide the first biochemical evidence for the requirement of the p50(cdc37)-Hsp90 complex in protein kinase regulation and for Raf-1 function in particular.  (+info)

Cyclin D-CDK subunit arrangement is dependent on the availability of competing INK4 and p21 class inhibitors. (5/39504)

The D-type cyclins and their major kinase partners CDK4 and CDK6 regulate G0-G1-S progression by contributing to the phosphorylation and inactivation of the retinoblastoma gene product, pRB. Assembly of active cyclin D-CDK complexes in response to mitogenic signals is negatively regulated by INK4 family members. Here we show that although all four INK4 proteins associate with CDK4 and CDK6 in vitro, only p16(INK4a) can form stable, binary complexes with both CDK4 and CDK6 in proliferating cells. The other INK4 family members form stable complexes with CDK6 but associate only transiently with CDK4. Conversely, CDK4 stably associates with both p21(CIP1) and p27(KIP1) in cyclin-containing complexes, suggesting that CDK4 is in equilibrium between INK4 and p21(CIP1)- or p27(KIP1)-bound states. In agreement with this hypothesis, overexpression of p21(CIP1) in 293 cells, where CDK4 is bound to p16(INK4a), stimulates the formation of ternary cyclin D-CDK4-p21(CIP1) complexes. These data suggest that members of the p21 family of proteins promote the association of D-type cyclins with CDKs by counteracting the effects of INK4 molecules.  (+info)

Cell growth inhibition by farnesyltransferase inhibitors is mediated by gain of geranylgeranylated RhoB. (6/39504)

Recent results have shown that the ability of farnesyltransferase inhibitors (FTIs) to inhibit malignant cell transformation and Ras prenylation can be separated. We proposed previously that farnesylated Rho proteins are important targets for alternation by FTIs, based on studies of RhoB (the FTI-Rho hypothesis). Cells treated with FTIs exhibit a loss of farnesylated RhoB but a gain of geranylgeranylated RhoB (RhoB-GG), which is associated with loss of growth-promoting activity. In this study, we tested whether the gain of RhoB-GG elicited by FTI treatment was sufficient to mediate FTI-induced cell growth inhibition. In support of this hypothesis, when expressed in Ras-transformed cells RhoB-GG induced phenotypic reversion, cell growth inhibition, and activation of the cell cycle kinase inhibitor p21WAF1. RhoB-GG did not affect the phenotype or growth of normal cells. These effects were similar to FTI treatment insofar as they were all induced in transformed cells but not in normal cells. RhoB-GG did not promote anoikis of Ras-transformed cells, implying that this response to FTIs involves loss-of-function effects. Our findings corroborate the FTI-Rho hypothesis and demonstrate that gain-of-function effects on Rho are part of the drug mechanism. Gain of RhoB-GG may explain how FTIs inhibit the growth of human tumor cells that lack Ras mutations.  (+info)

Neu differentiation factor stimulates phosphorylation and activation of the Sp1 transcription factor. (7/39504)

Neu differentiation factors (NDFs), or neuregulins, are epidermal growth factor-like growth factors which bind to two tyrosine kinase receptors, ErbB-3 and ErbB-4. The transcription of several genes is regulated by neuregulins, including genes encoding specific subunits of the acetylcholine receptor at the neuromuscular junction. Here, we have examined the promoter of the acetylcholine receptor epsilon subunit and delineated a minimal CA-rich sequence which mediates transcriptional activation by NDF (NDF-response element [NRE]). Using gel mobility shift analysis with an NRE oligonucleotide, we detected two complexes that are induced by treatment with neuregulin and other growth factors and identified Sp1, a constitutively expressed zinc finger phosphoprotein, as a component of one of these complexes. Phosphatase treatment, two-dimensional gel electrophoresis, and an in-gel kinase assay indicated that Sp1 is phosphorylated by a 60-kDa kinase in response to NDF-induced signals. Moreover, Sp1 seems to act downstream of all members of the ErbB family and thus may funnel the signaling of the ErbB network into the nucleus.  (+info)

Induced expression of p16(INK4a) inhibits both CDK4- and CDK2-associated kinase activity by reassortment of cyclin-CDK-inhibitor complexes. (8/39504)

To investigate the mode of action of the p16(INK4a) tumor suppressor protein, we have established U2-OS cells in which the expression of p16(INK4a) can be regulated by addition or removal of isopropyl-beta-D-thiogalactopyranoside. As expected, induction of p16(INK4a) results in a G1 cell cycle arrest by inhibiting phosphorylation of the retinoblastoma protein (pRb) by the cyclin-dependent kinases CDK4 and CDK6. However, induction of p16(INK4a) also causes marked inhibition of CDK2 activity. In the case of cyclin E-CDK2, this is brought about by reassortment of cyclin, CDK, and CDK-inhibitor complexes, particularly those involving p27(KIP1). Size fractionation of the cellular lysates reveals that a substantial proportion of CDK4 participates in active kinase complexes of around 200 kDa. Upon induction of p16(INK4a), this complex is partly dissociated, and the majority of CDK4 is found in lower-molecular-weight fractions consistent with the formation of a binary complex with p16(INK4a). Sequestration of CDK4 by p16(INK4a) allows cyclin D1 to associate increasingly with CDK2, without affecting its interactions with the CIP/KIP inhibitors. Thus, upon the induction of p16(INK4a), p27(KIP1) appears to switch its allegiance from CDK4 to CDK2, and the accompanying reassortment of components leads to the inhibition of cyclin E-CDK2 by p27(KIP1) and p21(CIP1). Significantly, p16(INK4a) itself does not appear to form higher-order complexes, and the overwhelming majority remains either free or forms binary associations with CDK4 and CDK6.  (+info)

Genotoxin-based DNA-damaging agents and cell-cycle inhibitors cause damage to DNA, activating checkpoints and inducing apoptosis in nearly all of the proliferating cells. Even though severe side effects are associated with these therapies, they are the most effective therapies in early stages of cancer. However, as cancer progresses, cancer cells accumulate more mutations, abrogating checkpoint functions and apoptosis-inducing programs, making them resistant to genotoxin-based treatments. More recently developed targeted therapies use drugs that inhibit specific gene or mutated gene products whose activities are important in cancer development and growth in particular types of cancer. Generally they are less toxic, yet their effects can be very dramatic, shrinking tumors within days. However, there are many practical problems with this approach. For example, inactivating one oncogene with its many variants may not be possible with just one targeted drug (1). Moreover, choosing just one ...

ZSTK474 is a novel orally applicable phosphoinositide 3-kinase-specific inhibitor that strongly inhibits cancer cell proliferation. Combination treatment using X-rays then ZSTK474 given orally for 8 days, starting 24h post-irradiation, significantly enhanced cell growth inhibition. The combined effect was also observed for clonogenic survival with continuous ZSTK474 treatment. Western blot analysis showed enhanced phosphorylation of Akt and GSK-3β by X-irradiation, whereas phosphorylation was inhibited by ZSTK474 treatment alone. Treatment with ZSTK474 after X-irradiation also inhibited phosphorylation, and remarkably inhibited xenograft tumor growth.
Brain p38α mitogen-activated protein kinase (MAPK), a potential therapeutic target for cognitive dysfunction based on the neuroinflammation-synaptic dysfunction cycle of pathophysiology progression, offers an innovative pharmacological strategy via inhibiting the same activated target in both glia and neurons, thereby enhancing the possibility for efficacy. The highly selective, brain-penetrant p38αMAPK inhibitor MW150 attenuates cognitive dysfunction in two distinct Alzheimers disease (AD)-relevant models and avoids the problems encountered with previous mixed-kinase inhibitor drug candidates. Therefore, it is essential that the glial effects of this CNS-active kinase inhibitor be addressed in order to anticipate future use in clinical investigations. We explored the effects of MW150 on glial biology in the AD-relevant APP/PS1 knock-in (KI) mouse model where we previously showed efficacy in suppression of hippocampal-dependent associative and spatial memory deficits. MW150 (2.5 mg/kg/day) was

Angiotensin converting enzyme inhibitors cause cough in some patients, but the mechanism of this effect is not known. Six patients in whom these inhibitors had caused cough and a further two patients in whom they were suspected to have caused worsening of bronchial asthma were studied. Nine patients in whom angiotensin converting enzyme inhibitors had not been associated with cough served as controls. In the controls lung function and bronchial reactivity were measured once; for the study patients these and the cough index were measured twice before rechallenge for two weeks with an angiotensin enzyme inhibitor and once afterwards. Rechallenge with drug for two weeks caused a significant decrease in the mean concentration of histamine causing a 35% fall in airways conductance and a significant increase in the cough index. Patients with cough showed bronchial hyperactivity compared with the controls, which increased after rechallenge with the inhibitors.. Cough associated with converting enzyme ...
One misconception that slips its way past most of us is the belief that soy was consumed for many years by Asian cultures and that they are among the most healthy, so if we consume soy now, we should all be fine. While this is true, there is a glaring difference between how ancient Asia prepared soy and how we do today. That key difference: fermenting the soy.. Un-fermented soybeans, what we mainly eat today, contain large quantities of natural toxins or anti-nutrients. Some of the most important to avoid are potent enzyme inhibitors that block the action of trypsin and other enzymes needed for protein digestion. These inhibitors are tightly folded proteins that do not deactivate during the cooking process. Without being deactivated, they have the ability to produce serious gastric distress, reduce protein digestion and chronic deficiencies in amino acid uptake. Several tests were done on animals that showed diets high in trypsin inhibitors cause enlargement and pathological conditions of the ...

Effects of Nerve Growth Factor and Nitric Oxide Synthase Inhibitors on Amyloid Precursor Protein mRNA Levels and Protein Stability
BACKGROUND: 15-Hydroxyprostaglandin dehydrogenase (15-PGDH, EC 1.1.1.141) is the key enzyme for the inactivation of prostaglandins, regulating processes such as inflammation or proliferation. The anabolic pathways of prostaglandins, especially with respect to regulation of the cyclooxygenase (COX) enzymes have been studied in detail; however, little is known about downstream events including functional interaction of prostaglandin-processing and -metabolizing enzymes. High-affinity probes for 15-PGDH will, therefore, represent important tools for further studies. PRINCIPAL FINDINGS: To identify novel high-affinity inhibitors of 15-PGDH we performed a quantitative high-throughput screen (qHTS) by testing |160 thousand compounds in a concentration-response format and identified compounds that act as noncompetitive inhibitors as well as a competitive inhibitor, with nanomolar affinity. Both types of inhibitors caused strong thermal stabilization of the enzyme, with cofactor dependencies correlating with

Nitric Oxide syntheses (NOS) are the family of enzymes which catalyzes the oxidation L-Arginine amino acid to nitric oxide molecule (NO) L-citrulline. Mammals contain three different NOS isozymes: Neuronal NOS (nNOS, in the brain), inducible NOS (iNOS, in macrophage cells), endothelial NOS (eNOS, the inner walls of blood vessels). Nitric Oxide (NO) is an important messenger molecule, which regulates several physiological functions in cardiovascular system and neuronal cells in the brain. Indeed, NO is a free radical gaseous molecule under normal conditions and highly toxic substance to our cells. In our body, it is produced locally at proper concentration at proper time. In endothelial cells, it relaxes smooth muscle causing to decrease blood pressure. Macrophage cells generate NO as an immune defense system to destroy microorganisms and pathogens. In our brain under certain pathological conditions after a certain ages produced excessive NO, causes tissue damage and oxidative stress. This leads ...

Biologically targeted cancer agents, including signal transduction inhibitors like mammalian target of rapamycin inhibitors (MTIs), have shown great promise in treating hematologic malignancies. A Phase 1 trial of sirolimus (an MTI) alone performed at CHOP has been well tolerated with no DLTs and has evidence of hitting the biologic target. While signal transduction inhibitors may be efficacious as single agents, it is more likely that these targeted agents will demonstrate greater efficacy in combination with other cytotoxic agents.Based upon pre-clinical humanized ALL mouse models we propose to study the toxicity and efficacy of adding sirolimus to oral methotrexate in relapsed and refractory patients.. Patients , 25 years of ...

Thousands of regions with higher than average mCG levels, which we term enriched residual methylation loci (ERML), were identified. We further show that persistence of mCG at a subset of these loci, including ERVs, germ-line genes, and a subgroup of imprinted DMRs, is dependent upon Setdb1. Finally, we provide evidence that Setdb1-mediated H3K9me3 promotes the stability of mCG at ERML at least in part by inhibiting Tet-dependent oxidation in these areas. Outcomes Characterization of Enriched Residual Methylation Loci in DKO mESCs. To comprehensively map the genomic areas that stay hypermethylated in the lack of the de novo Dnmts, we examined the genome-wide distribution of DNA methylation in past due passing DKO (passing 33) and WT (passing 39) parental mESCs by methylC-seq. In keeping with earlier studies, we discovered that apart from nearly ...

CDK4/6 inhibitors are considered a breakthrough in cancer therapy. Currently approved for breast cancer treatment, CDK4/6 inhibitors are extensively tested in other cancer subtypes. Frequently observed side effects include hematological abnormalities such as reduced numbers of neutrophils, erythroid cells and platelets that are associated with anemia, bleedings and a higher risk of infections. To understand whether the adverse effects within the hematopoietic system are related to CDK4 or CDK6 we generated transgenic mice that lack either CDK4 or CDK6 in adult hematopoiesis. Anemia and perturbed erythroid differentiation are associated with the absence of CDK6 but did not manifest in CDK4-deficient mice. Total CDK6 knockout mice accumulate the most dormant fraction of hematopoietic stem cells due to an impaired exit of the quiescent state. We recapitulated this finding by deleting CDK6 in adult hematopoiesis. In addition, unlike total CDK6 knockout, all stem cell fractions were affected and ...
Most potent protein kinase inhibitors act by competing with ATP to block the phosphotransferase activity of their targets. families encoded by the human genome and major constituents of most intracellular signaling cascades (Manning et al., 2002b),(Manning et al., 2002a). These signaling enzymes play important functions in countless cellular pathways, and the proper regulation of their activity is essential for normal cellular behavior. Aberrant kinase function is usually linked to numerous diseases, and a number of kinases are promising targets for the development of small molecule-based therapies (Cohen and Alessi, 2013). Currently, Ehk1-L a majority of potent and selective kinase inhibitors block phosphotransferase activity by competing with ATP (Zhang et al., 2009). While many of these inhibitors are able to interact with the ATP-binding clefts of kinases in an active conformation, a subset of inhibitors are conformation-selective, in that they only bind to their targets if conserved ...
Increased basal ET-1 release by NOS inhibitor was observed in only 2 of 9 studies with static cultures36,37 (Figure). Furthermore, in these 2 studies, the increased ET-1 release was determined after prolonged incubation with NOS inhibitor (ie, 637 and 24 hours36). Thus, the observed ET-1 release36,37 is not reflective of possible acute negative regulation of ET-1 release by NO.. Other studies failed to demonstrate increased ET-1 release after extended incubation (3-24 hours) with NOS inhibitor27,35,38-41 (Figure). Importantly, the general inability of NOS inhibitor to increase ET-1 release does not seem to be because of the failure of NOS inhibitor to decrease NO because NOS inhibitor for 8 hours decreased basal NO by 75% but did not increase ET-1 release41 (Figure; Figure S1).. The effect of NO inactivation on basal ET-1 release was also examined with oxyhemoglobin, which binds NO38,39,42,43 (Figure). Although exposure to oxyhemoglobin for 1 to 24 hours increased ET-1 release, it is likely that ...
The Receptor Tyrosine Kinase (RTK) Met influences behaviour of several cancers by controlling growth, survival and metastasis. Recently, compartmentalisation of signals generated by RTKs, due to their endocytosis / trafficking, has emerged as a major determinant of various cell functions. The aim of my project was to study oncogenic Met signalling in relation to endosomal trafficking and to determine the consequences of such spatial changes on tumour cell growth and migration in vitro and in vivo. The model studied was NIH3T3 cells stably transfected with Wild type (Wt) Met or with three distinct mutants reported in human cancers. I found that two activating mutations in the kinase domain are highly tumorigenic in vivo. Using functional assays and tumour growth experiments, I demonstrated that one mutant is highly sensitive to Met specific tyrosine kinase inhibitors (TKI) while another is resistant. Such results suggested that therapeutical approaches to these mutants should be different. ...

Studied compounds were also submitted to the antifungal assay. The best antifungal activity was detected for 16 with MIC at 0.125 and 0.25 mg/mL against C. albicans and C. parapsilosis, respectively.
Mono- and Stereopictres of 5.0 Angstrom coordination sphere of Zinc atom in PDB 1zef: Structure of Alkaline Phosphatase From Human Placenta in Complex With Its Uncompetitive Inhibitor L-Phe
Since the late 1980s, when nitric oxide (NO) was first shown to play a physiological role in mammals, this small molecule has been found to be a key mediator of an extraordinary variety of biological processes including blood pressure regulation, learning and memory, penile erection, digestion and the fighting of infection and cancer. Researchers at NYU School of Medicine have shown that bacteria also use NO to protect against oxidative stress and a new study by the same team shows that a broad spectrum of antibacterial drugs kill bacteria (at least in part) by inducing oxidative stress and that this effect is opposed by NO.. As well as opposing the antibacterial effects of oxidative stress, NO also reduced the effectiveness of antibiotics by chemical modifications that resulted in detoxification. Antibiotics were found to be more potent when the NO-mediated bacterial defence was eliminated, suggesting that co-administration of an inhibitor of NO-synthase could increase the effectiveness of ...

As a result, we chosen three pairs of characterized13 previously, 41 DGBCs and SCs and exposed these cells to Trametinib. The consequences on metabolic activity of Trametinib are less pronounced in the slowly dividng41 SCs than in the fast dividing41 DGBCs (Fig.?4A). The SC/DGBC percentage for the population doubling occasions of 35 cells is definitely 2.1, of 38 is 1.7, and of 40 is 1.913; this suggests that MEK inhibition might strongly impact proliferation in GB cells. As the level of sensitivity of the founded cell lines (Fig.?1A) lies between that of SCs and DGBCs, we continued with the same concentration of Trametinib, 30?nM. Next, we verified that ERK phosphorylation is also inhibited in the chosen concentration for at least ...
