Therefore, there is an unmet …
A critical role of Cyclophilins, mostly Cyclophilin A (CyPA), in the replication of HCV is supported by a growing body of in vitro and in vivo evidence. CyPA probably interacts directly with nonstructural protein 5A to exert its effect, through its peptidyl-prolyl isomerase activity, on maintaining the proper structure and function of the HCV replicase. The major proline substrates are located in domain II of NS5A, centered around a
Restoration of blood flow after myocardial infarction (MI), surgery or fibrinolytic therapy is necessary, but can lead to cardiomyocyte dysfunction within a generalised condition commonly known as "reperfusion injury". The role of cyclophilins, heat shock proteins (HSP), and the mitochondrial chaperone complex (MCC), was studied in this pathological condition. In vitro and in vivo models were used to replicate conditions of ischaemia/reperfusion (IR) injury. H9c2 and COS-7 cell lines were employed in nitric oxide (NO) donor and transfection applications. Experimental protocols were used to determine mitochondrial membrane potential (MMP), mitochondrial morphology, protein expression, enzyme activity and cell damage in these models. No difference was observed in activity or expression in cyclophilin or expression of the MCC in any of the models. It was noted that in the in vitro model, cell death was predominantly necrotic with only a minority of cells undergoing apoptosis, and as the degree of ...

This chemotactic capacity is dependent upon interaction of cyclophilins with the cell surface signaling receptor CD147. Elevated levels of extracellular cyclophilins have been documented in several inflammatory diseases. We propose that extracellular cyclophilins, via interaction with CD147, may contribute to the recruitment of leukocytes from the periphery into tissues during inflammatory responses. In this study, we examined whether extracellular ...

Research and training opportunities are available in a laboratory of the National Research Council of Italy for a postgraduate or postdoctoral student in the field of molecular parasitology. The laboratory is about to be relocated near Rome, in a multidisciplinary research complex comprising a European facility for the study of mouse mutants and four research groups of the EMBL. The proposed project is based on the study of cyclophilins (cyclosporin binding proteins) of the human parasites belonging to the genus Schistosoma. Molecular cloning and biochemical studies of schistosome cyclophilins are already under way in the host laboratory. An interest in cyclophilins is due to their likely role in mediating the antiparasitic effects of cyclosporin A and its derivatives. Supervision and research facilities will be provided to students who have been successful in applying to the Training and Mobility of Researchers Programme of the European Community (see the call for proposals under ...

Author Summary Cyclophilins are proteins that catalyze the isomerization of prolines, interconverting this structurally important amino acid between cis and trans isomers. Although there are 17 cyclophilins in the human genome, the function of most cyclophilin isoforms is unknown. At least some members of this protein family are of interest for clinically relevant drug design, as they are targets of the drug cyclosporin, which is used as an immunosuppressant to treat patients following organ transplantation. The absence of a comprehensive picture of the similarities and differences between the different members of this protein family precludes effective and specific drug design, however. In the current study we undertake such a global structure∶function analysis. Using biochemical, structural, and computational methods we characterize the human cyclophilin family in detail and suggest that there is a previously overlooked region of these enzymes that contributes significantly to isoform diversity.

eng] Cyclophilin-D (CyP-D) is a peptidyl prolyl cis/trans isomerase located in the mitochondrial matrix of mammalian cells. The subcellular localization of the protein is determined by the presence of a mitochondrial targeting presequence. In the first part of this work, we characterized human CyP-D presequence allowing the protein translocation into mitochondria. We showed that the 16 first amino acid of the presequence are necessary and sufficient to form a functional presequence and to address hCyP-D into mitochondria. One of the main physiological roles of CyP-D is to activate the mitochondrial permeability transition pore (mPTP) opening. The mPTP is a protein complex formed during oxidative stress and leading to cell necrosis. Thus, CyP-D may be considered as a necrosis inductor. Nevertheless, several studies have also shown that CyP-D exhibits a protective role toward apoptosis induced by oxidative stress. However, the mechanism implicated in the cellular protection conferred by CyP-D is ...
Numerous mechanisms have been suggested for how bacterial toxins kill susceptible mammalian cells. Several recent studies demonstrated the importance of mitochondrial targeting of toxins produced by H. pylori, C. difficile, and S. aureus to mitochondria (56). In these cases toxin-mediated cell death was caspase independent and did not result in typical PTPs in the MOM (14, 18).. Previously, we reported that M. haemolytica LKT induces apoptosis of BL-3 cells in a caspase-9-dependent manner and that in mitochondria isolated from LKT-intoxicated BL-3 cells there was gross damage to the MOM (4). Based on these observations, we hypothesized that LKT is transported into the cell and binds directly to mitochondria. In the present study, we first demonstrated that full-length LKT protein could be identified in purified mitochondrial lysates from LKT-treated BL-3 cells (Fig. 1A). Transfection of anti-LKT antibodies into BL-3 cells prevented binding of LKT to mitochondria. Confocal microscopy and flow ...

PPIase that catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and may therefore assist protein folding. Involved in regulation of the mitochondrial permeability transition pore (mPTP). It is proposed that its association with the mPTP is masking a binding site for inhibiting inorganic phosphate (Pi) and promotes the open probability of the mPTP leading to apoptosis or necrosis; the requirement of the PPIase activity for this function is debated. In cooperation with mitochondrial TP53 is involved in activating oxidative stress-induced necrosis. Involved in modulation of mitochondrial membrane F(1)F(0) ATP synthase activity and regulation of mitochondrial matrix adenine nucleotide levels. Has anti-apoptotic activity independently of mPTP and in cooperation with BCL2 inhibits cytochrome c-dependent apoptosis.

article{203b97eb-96fd-4fd8-a31f-dd57ba747ae5, abstract = {,p,Mitochondria control bioenergetics and cell fate decisions, but how they influence nuclear gene expression is understood poorly. Here, we show that deletion or reduction in the levels of cyclophilin D (CypD, also called Ppif), a mitochondrial matrix peptidyl prolyl isomerase and apoptosis regulator, results in increased cell proliferation and enhanced cell migration and invasion. These responses are associated with extensive transcriptional changes, modulation of a chemokine/chemokine receptor gene signature, and activation of the pleiotropic inflammatory mediator, STAT3. In the absence of CypD, active STAT3 enhances cell proliferation via accelerated entry into S-phase and stimulates autocrine/paracrine cell motility through Cxcl12-Cxcr4-directed chemotaxis. Therefore, CypD directs mitochondria-to-nuclei inflammatory gene expression in normal and tumor cells. This pathway may contribute to malignant traits under conditions of CypD ...
The mechanism by which cyclosporin A (CsA) inhibits vaccinia virus (VV) replication is still unclear. The present study addresses the question of whether CsA-binding proteins named cyclophilins (Cyps) are involved in the anti-VV activity of CsA. Six CsA analogues were analysed, and their affinity for Cyps in VV-infected BSC-40 cells and their potency as inhibitors of VV replication were evaluated. It was demonstrated that analogues with strong Cyp-binding activity, such as CsC, CsG and [MeAla6]CsA, also exhibit a strong antiviral effect. In contrast, drugs with low ([MeBm2t1]CsA and CsH) or no ([MeLeu11]CsA) affinity for Cyps show poor or no antiviral activity. The data obtained suggest a correlation between the ability of CsA to block VV replication and Cyp binding activity, and indicate the involvement of Cyps in the VV replicative cycle. They also suggest that the anti-VV action of CsA may occur by a pathway distinct from that involved in the immunosuppressive effect of the drug.

Drug-induced mitochondrial dysfunction has been implicated in many types of organ toxicity, including liver and intestine. The induction of the mitochondrial permeability transition (mPT) has been seen as a mechanism of this toxicity. The mitochondrial matrix protein cyclophilin D (CypD) is a key regulator of the mPT, lending itself as a potential target for therapeutic intervention. The overall aim of this research project is to explore the mPT as a potential mediator of drug-induced mitochondrial toxicity in intestine and liver. Small intestinal ulceration is a frequent and serious adverse effect associated with the use of non-steroidal anti-inflammatory drugs. Mitochondria have been implicated in ulcer development. We have shown that inhibition of the mPT pore by pharmacologic blockade of CypD resulted in significant protection from diclofenac injury in cultured enterocytes and a 70% reduction in intestinal ulcers in mice. Furthermore, Ppif-/- (the gene encoding CypD) mice show 80% ulcer reduction

Astrocytes extend highly branched processes that form functionally isolated microdomains, facilitating local homeostasis by redistributing ions, removing neurotransmitters, and releasing factors to influence blood flow and neuronal activity. Microdomains exhibit spontaneous increases in calcium (Ca2+), but the mechanisms and functional significance of this localized signaling are unknown. By developing conditional, membrane-anchored GCaMP3 mice, we found that microdomain activity that occurs in the absence of inositol triphosphate (IP3)-dependent release from endoplasmic reticulum arises through Ca2+ efflux from mitochondria during brief openings of the mitochondrial permeability transition pore. These microdomain Ca2+ transients were facilitated by the production of reactive oxygen species during oxidative phosphorylation and were enhanced by expression of a mutant form of superoxide dismutase 1 (SOD1 G93A) that causes astrocyte dysfunction and neurodegeneration in amyotrophic lateral sclerosis ...
The participation of mitochondria in cellular and neuronal Ca2+ homeostatic networks is now well accepted. Yet, critical tests of specific mitochondrial pathways in neuronal Ca2+ responses have been hampered because the identity of mitochondrial proteins that must be integrated within this dynamic system remain uncertain. One putative pathway for Ca2+ efflux from mitochondria exists through the formation of the permeability transition pore (PTP) that is often associated with cellular and neuronal death. Here, we have evaluated neuronal Ca2+ dynamics and the PTP in single adult neurons in wild-type mice and those missing cyclophilin D (CyPD), a key regulator of the PTP. Using high-resolution time-lapse imaging, we demonstrate that PTP opening only follows simultaneous activation with two physiological stimuli that generate critical threshold levels of cytosolic and mitochondrial Ca2+. Our results are the first to demonstrate CyPD-dependent PTP opening in normal neuronal Ca2+ homeostatic ...
Calcium modulating ligand (CAMLG or CAML), also known as calcium-modulating cyclophilin ligand, is a signalling protein recognized by the TNF receptor TACI. The immunosuppressant drug cyclosporin A blocks a calcium-dependent signal from the T-cell receptor (TCR) that normally leads to T-cell activation. When bound to cyclophilin B, cyclosporin A binds and inactivates the key signaling intermediate calcineurin. The protein encoded by this gene functions similarly to cyclosporin A, binding to cyclophilin B and acting downstream of the TCR and upstream of calcineurin by causing an influx of calcium. This integral membrane protein appears to be a new participant in the calcium signal transduction pathway, implicating cyclophilin B in calcium signaling, even in the absence of cyclosporin. CAMLG has been shown to interact with TNFRSF13B.

To characterize the cellular action mechanism of Debio 0507, we compared the major DNA adducts formed by Debio 0507- and oxaliplatin-treated HCT116 human colon carcinoma cells by a combination of inductively coupled plasma mass spectrometry (ICP-MS) and ultraperformance liquid chromatography mass spectrometry (UPLC-MS/MS). HCT116 cells were treated with IC50 doses of Debio 0507 or oxaliplatin for 3 days. Total cellular Pt-DNA adducts were determined by ICP-MS. The DNA was digested, and the major Pt-DNA adducts formed by both drugs were characterized by UPLC/MS/MS essentially as described previously for cisplatin (Baskerville-Abraham et al. in Chem Res Toxicol 22:905-912, 2009). The Pt level/deoxynucleotide was 7.4/104 for DNA from Debio 0507-treated cells and 5.5/104 for oxaliplatin-treated cells following a 3-day treatment at the IC50 for each drug. UPLC-MS/MS in the positive ion mode confirmed the major Pt-DNA adducts formed by both drugs were dach-Pt-d(GpG) (904.2 m/z → 610 m/z and 904.2 m/z →

Rescue and Role of Complex I in Myocardial Ischemic Injury: Members of the Bcl-2 family function at the mitochondrial outer membrane to regulate programmed cell death, or apoptosis. Bax and Bak are multi-domain pro-apoptotic members of the family, but their activity is directly or indirectly regulated by proteins of the BH3-only subfamily (Bcl-2 relatives that only share homology in domain 3). We are interested in Bid, a BH3-only protein that is proteolytically activated during ischemia/reperfusion and targets the mitochondria to initiate apoptosis. Mitochondria can promote necrotic cell death through a second pathway involving a mysterious entity known as the Mitochondrial Permeability Transition Pore, which includes cyclophilin D and other components that are the subject of intense investigation. We hypothesize that the electron transfer Complex I may be a part of the pore and may be regulated by Complex I. We have developed a cell-permeable therapeutic protein that can protect the heart ...

Background:. Since the introduction of cisplatin, carboplatin and oxaliplatin, several new generations of platinum analogues have been developed as candidates for chemotherapy. DEBIO 0507/NC-4016 is a DACH-Platin Polymeric Micelle. The main objectives of this project were to assess pharmacokinetic (PK) profile of DEBIO 0507 and evaluate its efficacy in preclinical studies against a broad spectrum of experimental tumors including syngenic, xenogenic tumor models and a cisplatin-resistant cell line.. Methods:. PK and biodistribution studies were conducted in multiple matrices (blood, tumor, liver, spleen, kidneys and pancreas) collected in mice bearing C38 mouse colon carcinoma and treated with a single IV injection of DEBIO 0507 at 2 mg Pt/kg.. Antitumor activity of DEBIO 0507 intravenously injected every 4, 7 or 14 days at different doses was investigated in C38 mouse colon carcinoma bearing C57BL/6 mice. Antitumor effect of DEBIO 0507 was also assessed in a panel of human tumor xenografted in ...
Activated carbons were characterized texturally and chemically before and after treatment, using surface area determination in the BET model, Boehm titration, TPR, DRX and immersion calorimetry. The adsorption capacity and the kinetics of sulphur compound removal were determined by gas chromatography. It was established that the propanethiol retention capacity is dependent on the number of oxygenated groups generated on the activated carbon surface and that activated carbon modified with CuO at 0.25 M shows the highest retention of propanethiol. Additionally is proposed a mechanism of decomposition of propenothiol with carbon-copper system.
