The RGD peptide is the binding motif of fibronectin to cell adhesion molecules. RGD peptide acts as an inhibitor of integrin-ligand interactions and can induce apoptosis in the absence of signals and integrin-mediated cell clustering. Research demonstrates that RGD peptides promote apoptosis through activation of conformation changes that enhance pro-caspase-3 activation and autoprocessing. The RGD peptide can serve as a cell adhesion site of extracellular matrix, cell surface proteins, and integrins. In addition, RGD peptide can inhibit ACK-2 activation through cell adhesion. ...
Novel synthetic Arg-Gly-Asp containing peptides which have high affinity and specificity for their receptors by virtue of restrictions on their stereochemical conformation. Such restrictions can be provided by cyclization, by inclusion into a constraining conformational structure such as a helix, by providing an additional chemical structure such as an amide or an enantiomer of a naturally occurring amino acid, or by other methods. In particular, there are provided cyclic peptides having increased affinity and selectivity for the certain receptors over that of linear, Arg-Gly-Asp-containing synthetic peptides.
Part of the binding-protein-dependent transport system for oligopeptides; probably responsible for the translocation of the substrate across the membrane.
Sequences of human proteins are frequently prepared as synthetic oligopeptides to assess their functional ability to act as compounds modulating pathways involving the parent protein. Our objective was to analyze a set of oligopeptides, to determine if their solubility or activity correlated with features of their primary sequence, or with features of properties inferred from three-dimensional structural models derived by conformational searches. We generated a conformational database for a set of 78 oligopeptides, derived from human proteins, and correlated their 3D structures with solubility and biological assay activity (as measured by platelet activation and inhibition). Parameters of these conformers (frequency of coil, frequency of turns, the degree of packing, and the energy) did not correlate with solubility, which was instead partly predicted by two measures obtained from primary sequence analysis, that is, the hydrophobic moment and the number of charges. The platelet activity of ...

T2 - Comparison of the relative activities of triflavin, an Arg-Gly-Asp-containing peptide and anti-α(v)β3 integrin monoclonal antibody. AU - Sheu, Joen Rong. AU - Yen, Mao Hsiung. AU - Kan, Ya Chen. AU - Hung, Wei Chun. AU - Chang, Pei Te. AU - Luk, Hsiang Ning. PY - 1997/10/20. Y1 - 1997/10/20. N2 - Disintegrin which contains the amino acid sequence Arg-Gly-Asp (RGD), has been implicated as a recognition site in interactions between extracellular matrix (ECM) and cell membrane receptors. Triflavin, a 7.5 kDa cysteine-rich polypeptide purified from Trimeresurus flavoviridis snake venom, belongs to a family of disintegrins. Integrin α(v)β3 has recently been identified as a marker of angiogenic blood vessels and therefore anti-α(v)β3 mAb may significantly inhibit angiogenesis. Therefore, this study was designed to compare the relative activity of triflavin and anti-α(v)β3 mAb in human umbilical vein endothelial cell (HUVEC) ...
The results of the IMPAACT/PACTG 1020A trial in children and adolescents indicate that, in the absence of ritonavir boosting, atazanavir can achieve protocol-defined PK targets-but only when used at higher doses of atazanavir (on a mg/kg body weight or mg/m2 body surface area basis) than doses currently recommended in adults. In IMPAACT/PACTG 1020A, children aged ,6 to ,13 years required atazanavir dosing of 520 mg/m2 per day of atazanavir capsule formulation to achieve PK targets.8 Unboosted atazanavir at this dose was well tolerated in those aged ,13 years who were able to swallow capsules.11 Doses required for older adolescents were greater than the adult approved dose of 400 mg atazanavir given without ritonavir boosting once daily; adolescents aged ,13 years required atazanavir dosing of 620 mg/m2 per day.8 In this study, the AUCs for the unboosted arms were similar to the ATV/r groups but the maximum plasma concentration (Cmax) was higher and minimum plasma concentration (Cmin) lower for ...

3762 In its normal life cycle, B. pertussis attaches to, and invades ciliated epithelia and macrophages of the human airways, using adhesins specialized for certain oligosaccharides and proteins on these cells. Here we report that B. pertussis uses similar mechanisms for invasion of a variety of human cancer cells in vitro, and exhibits potent, invasion-dependent, cytotoxicity. In a 30′ in vitro invasion assay, B. pertussis invaded human SKmel-23 melanoma cells at 20-30 times the rate for normal human melanocytes and fibroblasts. B. pertussis invasion of SKmel-23 cells was inhibited by preincubation of cancer cells with glycosidase F, the plant lectins LPHA and TGP, human antibodies vs CD15 and CD11b, or the RGD tripeptide sequence-implying that the structural requirements for invasion included β1,6-branched N-glycans, Lewis × antigens, CD11b, and the sequence arg-gly-asp respectivelly. Invasion was also inhibited by preincubation of cancer cells with 3-methyladenine (3-MA), indicating a ...

In this study we focused on the signaling of V antigen-induced innate immunity responses. For the first time we demonstrate that a bacterial nonlipidated protein associated with virulence and derived synthetic oligopeptides are capable to induce IL-10 production via TLR2/CD14 signaling. In contrast to the pseudomonas rPcrV, rLcrV (range of activity: 10-100 nM) transmits signaling via TLR2 in a CD14-dependent manner leading to IL-10 induction which finally causes TNF-α suppression thus probably enabling yersiniae to evade the host innate immune system. Several lines of evidence obtained in vitro both in murine and human cell systems support this conclusion: (a) Only CD14-TLR2-cotransfected HEK 293 cells, but not cells transfected with TLR2 alone responded with NF-κB-dependent ELAM-1 promoter luciferase activity upon rLcrV stimulation. (b) Blocking anti-CD14 monoclonal antibodies, but not nonblocking isotype anti-CD14 antibodies completely abolished TNF-α suppression in LcrV-treated MonoMac-6 ...

Second, Table 3 in the article, outlining the toxicity associated with the regimens, is a gem. This is how we would like adverse events reported. From this table, it is apparent that it is important to keep in mind the small but definite risk of hypertension, dyspnea, and cardiac failure associated with carfilzomib. On the other hand, the risk of neuropathy is definitely lower with this drug compared with bortezomib. Finally, a comparison of overall survival results from other randomized trials in the relapsed setting (outlined well in the discussion section of the article) shows it is extremely difficult to achieve this magnitude of survival benefit, even with trials that lacked an active control equivalent. This reveals the value of carfilzomib as an added option for the treatment of myeloma. Take-Home Points HOW DO THE ENDEAVOR RESULTS change our current practice? With a definitive improvement in overall survival, ENDEAVOR ensconces the safety and efficacy of carfilzomib and provides evidence ...

The endomorphins are a group of endogenous opioid peptides consisting of endomorphin-1 (Tyr-Pro-Trp-Phe-NH2) and endomorphin-2 (Tyr-Pro-Phe-Phe-NH2). They are tetrapeptides with the highest known affinity and selectivity for the μ-opioid receptor. Endomorphin-1 is found in the nucleus of the solitary tract, the periventricular hypothalamus, and the dorsomedial hypothalamus, where it is found within histaminergic neurons and may regulate sedative and arousal behaviors. It is assumed that endomorphins are the cleavage products of a larger precursor, but this polypeptide or protein has not yet been identified. In rats similarly potent dosages of synthetic endomorphin and morphine produced comparable amounts of pain relief. However, the rats receiving morphine had motor skills and breathing that were significantly impaired, while the rats that received endomorphin did not. The morphine rats spent more time in the compartment where they had received morphine, while the endomorphin rats did not. Only ...
