Recombinant adenovirus-mediated gene transfer to genitourinary epithelium in vitro and in vivo. (1995)

Transitional cell carcinoma (TCC) of the bladder is associated with characterized lesions in dominant and recessive oncogenes. The understanding of the molecular basis of tumorigenesis in these instances makes possible the application of gene therapy strategies for TCC. In this regard, the ability to directly access the epithelium of the genitourinary (GU) tract via the urethra provides a practical means to implement these various gene therapy approaches. We thus explored vector strategies to accomplish direct in vivo transduction of GU epithelium. Initially, three human (HT 1197, HT 1376, T24) and one mouse (MBT-2) TCC cell lines were transduced using a recombinant adenoviral vector expressing the firefly luciferase reporter gene, rAd-CMV-Luc. In these studies, reporter gene expression was found to be significantly elevated above background for all four cell lines. Of note, the TCC cell lines HT 1197 and HT 1376 showed expression levels comparable with the cervical carcinoma cell line HeLa, a cell line previously shown to be highly susceptible to recombinant adenovirus-mediated gene transduction. An in vitro time course for T24 and MBT-2 using rAd-CMV-Luc showed peak expression 1 day after transduction for the T24 line and 3 days after transduction for the MBT-2 line, with detectable levels of expression persisting for at least 7 days. As a next step, human and mouse primary tissue deriving from the GU epithelium were transduced using rAd-CMV-Luc. In this assay, luciferase expression levels significantly above background were observed in both instances.(ABSTRACT TRUNCATED AT 250 WORDS)

Influence of Intestinal Bacterial Decontamination Using Metronidazole and Ciprofloxacin or Ciprofloxacin Alone on the Development of Acute Graft-Versus-Host Disease After Marrow Transplantation in Patients With Hematologic Malignancies: Final Results and Long-Term Follow-Up of an Open-Label Prospective Randomized Trial (1999)

In a single-center open-label prospective study, a total of 134 marrow transplant recipients with hematologic malignancies were randomly assigned to a bacterial decontamination medication using metronidazole and ciprofloxacin (n = 68) or ciprofloxacin alone (n = 66) during 5 weeks posttransplant. The development of grades II to IV acute graft-versus-host disease (GVHD) was defined as the primary study endpoint. According to the intention-to-treat, 17 patients (25%) randomized to the combined decontamination medication and 33 patients (50%) randomized to ciprofloxacin alone developed grades II to IV GVHD (P <.002). The higher frequency of grades II to IV acute GVHD in patients randomized to ciprofloxacin alone resulted from a more than twofold increased number of patients developing liver or intestinal involvement with acute GVHD compared with patients randomized to the combined decontamination medication (P <.003). The influence of the study medication on grades II to IV acute GVHD was significant only in recipients of transplants from genotypically HLA-identical sibling donors (n = 80), whereas in recipients of transplants from donors other than HLA-identical siblings (n = 54), grades II to IV acute GVHD frequencies between the study arms were not significantly different. The combined decontamination was associated with a significant reduction of culture growth of intestinal anaerobic bacteria during 5 weeks posttransplant (P <. 00001). In addition, the number of cultures with growth of anaerobic bacteria (P <.005) as well as the median concentrations of anaerobic bacteria in the posttransplant period (P <.0001) were higher in patients contracting grades II to IV acute GVHD. Neither chronic GVHD nor overall survival was significantly different between the two study arms. In patients with HLA-identical sibling donors who were treated in early disease stages, the 5-year survival estimate was slightly, but not significant, higher after the combined decontamination medication (60% +/- 11%) compared with ciprofloxacin alone (46% +/- 9%). In conclusion, the present study provides evidence that antimicrobial chemotherapy targeted to intestinal anaerobic bacteria in marrow transplant recipients significantly reduces the severity of acute GVHD and supports the theory that the intestinal anaerobic bacterial microflora plays a role in the pathogenesis of acute GVHD after human marrow transplantation.
Closely Related Mammals Have Distinct Asialoglycoprotein Receptor Carbohydrate Specificities (2004)

We recently reported that the rat asialoglycoprotein receptor binds oligosaccharides terminating with sialic acid (Sia) alpha2,6GalNAc. Despite a high percentage of identical amino acids in their sequences, orthologues of the asialoglycoprotein receptor (ASGP-R) in different mammals differ in their specificity for terminal Siaalpha2,6GalNAc. The recombinant subunit 1 of the ASGP-R from the rat (RHL-1 or rat hepatic lectin) and the mouse (MHL-1 or mouse hepatic lectin), which differ at only 12 positions in the amino acid sequence of their carbohydrate recognition domains, binds Siaalpha2,6GalNAcbeta1,4GlcNAcbeta1,2Man-bovine serum albumin and GalNAcbeta1,4GlcNAcbeta1,2Man-bovine serum albumin in ratios of 16:1.0 and 1.0:1.0, respectively. Mutagenesis was used to show that amino acids both in the immediate vicinity of the proposed binding site for terminal GalNAc and on the alpha2 helix that is distant from the binding site contribute to the specificity for terminal Siaalpha2,6GalNAc. Thus, multiple amino acid sequence alterations in two key locations contribute to the difference in specificity observed for the rat and mouse ASGP-Rs. We hypothesize that the altered specificity of ASPG-R orthologues in such evolutionarily closely related species reflects rapidly changing requirements for recognition of endogenous or exogenous oligosaccharides in vivo.

Controlled decoration of carbon nanotubes with nanoparticles (2006)

We present an efficient gas-phase route to decorate both single-walled and multiwalled carbon nanotubes with nanoparticles based on electrostatic force directed assembly. We show that, in addition to an intrinsic nanoparticle size selection, the packing density and the final size distribution of nanoparticles docking on nanotubes can be controlled during the assembly process. Our method enables in situ coating of nanotubes with nanoparticles. Due to the inherent material-independent nature of the electrostatic force, various compositions of such nanoparticle–nanotube structures can be produced using this new technique. These novel structures will enable new opportunities for exploring nanoscience, nanotechnology, and biotechnology.
Cell proliferation on fibrin: modulation by fibrinopeptide cleavage (1995)

Fibrin forms the cohesive network of hemostatic plugs and thrombi, and it also provides the temporary matrix for initial support of healing and revascularization. Because cell proliferation is needed for revascularization after vessel injury, we have characterized structural requirements of fibrin needed to support cell proliferation on fibrin in vitro. Proliferation of cultured human endothelial cells and fibroblasts was measured by 3H-thymidine incorporation on fibrin surfaces varying in structure. Fibrin prepared with thrombin and lacking both fibrinopeptides A and B (desAB fibrin) supported proliferation of both endothelial cells and fibroblasts. In contrast, fibrin prepared with reptilase, which cleaves only fibrinopeptide A, supported significantly less proliferation. Also, fibrin prepared by thrombin treatment of fibrinogen lacking residues beta 1-42 supported only a low level of proliferation. Therefore, fibrinopeptide B cleavage and exposure of beta 15-42 enhanced proliferation of cells on fibrin. Specific proteolytic inhibitors were used to eliminate the potential mitogenic effects of residual fibrin-bound thrombin. Additional controls showed that neither catalytically inactive thrombin nor addition of the thrombin receptor-activating peptide (SFLLRNPNDKYEPF [SFLL]) stimulated proliferation on desA fibrin. The results indicate that cell proliferation on fibrin is enhanced by fibrinopeptide B cleavage and exposure of the amino terminus of the fibrin beta chain. They also show that specific structural features of the temporary fibrin matrix formed at sites of injury may modulate the proliferative response of vascular cells.

Abstract 2403: Targeting 4-1BB in tumors enhances anti-tumor immune responses (2019)

Abstract 4-1BB (CD137) is a co-stimulatory receptor expressed on activated T cells and other immune cells and is associated with enhanced T cell proliferation, survival, and increased cytokine production upon engagement with its ligand (4-1BBL). We have previously shown that addition of agonistic 4-1BB antibody to tumor fragments increased tumor infiltrating lymphocyte (TIL) expansion in human melanoma and pancreatic tumors. Furthermore, agonistic 4-1BB antibody led to increased expression of maturation markers in resident dendritic cells (DCs) present within tumor fragments. While the role of 4-1BB in T cell biology is well described, little is known about 4-1BB signaling in tumor-resident DCs. We hypothesized that 4-1BB agonism in tumor-resident DCs would promote anti-tumor T cell immune responses. To evaluate the role of 4-1BB signaling on dendritic cells, murine bone marrow derived-DCs were cultured with agonistic 4-1BB antibody and loaded with OVA protein. Treatment with agonistic 4-1BB in vitro led to increased OVA-FITC uptake by DCs (32.6% compared to 15.9% in DCs treated with control antibody). DCs treated with agonistic 4-1BB antibody demonstrated increased T cell stimulatory capacity upon co-culture with OVA-specific OT-I and OT-II T cells. We next compared systemic and intralesional (IL) treatment with agonistic 4-1BB antibody. For the systemic model, mice were injected subcutaneously (SC) with B16 melanoma or Panc02 pancreatic tumor cells and treated by intraperitoneal injection of control or anti-4-1BB antibodies. Mice treated systemically with agonistic 4-1BB antibody exhibited a minimal reduction in tumor growth. In contrast, IL injection of agonistic 4-1BB antibody led to dramatic decreases in tumor growth. Next, we wanted to determine whether IL treatment with agonistic 4-1BB antibody would improve DC stimulatory capacity. Mice bearing B16 or Panc02 tumors were treated IL with normal control or anti-4-1BB antibody. After 7 days, tumor-resident CD11b+ DCs exhibited enhanced in vivo antigen uptake. In addition, an increased number of CD8+ T cells was measured within tumors treated with agonistic 4-1BB antibody (28.1% compared to 20% in NrIgG-treated Panc02OVA tumors and 19.45% compared to 7.3% in NrIgG treated B16-OVA tumors; p=0.0059). Together, these studies demonstrate that agonistic 4-1BB can enhance the ability of DCs to stimulate T cells and IL administration of agonistic 4-1BB antibody can significantly reduce tumor growth. This suggests that IL treatment of agonistic 4-1BB may yield greater efficacy than systemic therapy in patients with melanoma or pancreatic cancer.

The co-solvent Cremophor EL limits absorption of orally administered paclitaxel in cancer patients (2001)

The purpose of this study was to investigate the effect of the co-solvents Cremophor EL and polysorbate 80 on the absorption of orally administered paclitaxel. 6 patients received in a randomized setting, one week apart oral paclitaxel 60 mg m(-2) dissolved in polysorbate 80 or Cremophor EL. For 3 patients the amount of Cremophor EL was 5 ml m(-2), for the other three 15 ml m(-2). Prior to paclitaxel administration patients received 15 mg kg(-1) oral cyclosporin A to enhance the oral absorption of the drug. Paclitaxel formulated in polysorbate 80 resulted in a significant increase in the maximal concentration (C(max)) and area under the concentration-time curve (AUC) of paclitaxel in comparison with the Cremophor EL formulations (P = 0.046 for both parameters). When formulated in Cremophor EL 15 ml m(-2), paclitaxel C(max) and AUC values were 0.10 +/- 0.06 microM and 1.29 +/- 0.99 microM h(-1), respectively, whereas these values were 0.31 +/- 0.06 microM and 2.61 +/- 1.54 microM h(-1), respectively, when formulated in polysorbate 80. Faecal data revealed a decrease in excretion of unchanged paclitaxel for the polysorbate 80 formulation compared to the Cremophor EL formulations. The amount of paclitaxel excreted in faeces was significantly correlated with the amount of Cremophor EL excreted in faeces (P = 0.019). When formulated in Cremophor EL 15 ml m(-2), paclitaxel excretion in faeces was 38.8 +/- 13.0% of the administered dose, whereas this value was 18.3 +/-15.5% for the polysorbate 80 formulation. The results show that the co-solvent Cremophor EL is an important factor limiting the absorption of orally administered paclitaxel from the intestinal lumen. They highlight the need for designing a better drug formulation in order to increase the usefulness of the oral route of paclitaxel

Improving plasmid DNA-mediated liver gene transfer by prolonging its retention in the hepatic vasculature (2001)

This is the first demonstration of gene transfer to the liver via systemic administration without using any carrier system or physical force. Also, the technique provides new insights into the mechanism of hepatic gene transfer.
Control of the ppp(A2′p)nA System in HeLa Cells (1982)

HeLa cells have an unusually high level of ppp(A2'p)nA synthetase (n = 2 to greater than or equal to 4) even in the absence of interferon treatment. In accord with this ppp(A2'p)nA and ppp(A2'p)nA-mediated ribosomal RNA cleavage occur naturally in response to encephalomyocarditis virus infection in control as well as in interferon-treated cells. Despite this, in the absence of interferon treatment, encephalomyocarditis virus grows well in these cells. A possible explanation for this paradox is that the ppp(A2'p)nA dependent RNase is lost or inactivated at later times post-infection in control but not in interferon-treated cells. It appears, therefore, to be the prevention by interferon of the virus-mediated inhibition of the ppp(A2'p)n-dependent nuclease rather than the absolute level or induction of the ppp(A2'p)nA synthetase which is crucial for the activity of the ppp(A2'p)nA system in HeLa cells. These results provide evidence for a further level of control in the ppp(A2'p)nA system and show that limited ppp(A2'p)nA-mediated ribosomal RNA cleavage alone is not sufficient to cause an inhibition of virus growth.

Correlation of cytotoxicity with incorporation of ara-C into DNA. (1980)

We have employed cesium sulfate density gradient analysis to monitor the incorporation of 1-beta-D-arabinofuranosylcytosine (ara-C) into L1210 cellular nucleic acid. This methodology permits a distinct separation of RNA and DNA under nondegrading conditions. The results demonstrate specific incorporation of ara-C into DNA with less than 1% of total incorporation into nucleic acid being detectable in RNA. Moreover, we have found a highly significant relationship (p < 0.0001) between the incorporation of ara-C into DNA with the loss of clonogenic survival. This relationship had not been established due to the previous use of alkaline conditions that degrade (ara-C) DNA. Our results suggest that the incorporation of ara-C into DNA is one mechanism responsible for producing lethal cellular events.
Adenovirus Vaccines in the U.S. Military (1995)

Acute respiratory disease (ARD) due to adenoviruses caused significant morbidity in military training populations. Since 1971 ARD has been controlled by the use of live, enteric-coated, adenovirus (ADV) types 4 and 7 vaccines. This immunization program overcame significant problems in vaccine development. Due to a production delay, military training posts stopped ADV vaccine administration in spring 1994. The delivery of ADV vaccine resumed in late February 1995, but another production delay is anticipated. A generation of military medical people have not been exposed to the significant morbidity caused by adenoviruses and are unaware of the effectiveness of the ADV vaccine. ARD morbidity before ADV vaccines, the ADV vaccine development program, and current issues regarding the control of ARD due to adenoviruses in the military are discussed.
Role of Gap Junctions in Cardiac Conduction and Development (2000)

Gap junctions are membrane channels that mediate thecell-to-cell movement of ions and small metabolites.In the heart, gap junctions play an important role in impulse conduction. Studies over the last decade have re-vealed that gap junctions are encoded by a multigene family known as the connexins. There are at least 15 connexin genes in the vertebrate genome.1 Connexins have been referred to by 2 nomenclature systems, either according to the molecular weight of the protein or by its class as determined by protein sequence.1,2 The molecular weight designation will be used here in conformity with the study by Kirchhoff et al3 in this issue of Circulation Research. In the heart, there are 3 major connexin isotypes expressed: connexin (Cx)43 (a1 connexin), Cx45 (a6 connexin), and Cx40 (a5 connexin). Each of these connexins exhibits differ-ent channel properties and is regulated by different gating mechanisms. Cx43 is the only connexin known to be ex-

Orthorhombic LiMnO2 as a High Capacity Cathode for Li‐Ion Cells (1995)

Orthorhombic prepared at temperatures near 100°C was evaluated for suitability as a high‐capacity cathode for Li‐ion cells. test cells showed initial reversible capacities of about 170 mAh/g of . This is much larger than that typically obtained from cells, about 110 mAh/g. The capacity of the cells is divided approximately equally between 3 and 4 V plateaus. The cells exhibit little capacity loss with cycle number when restricted to either the 3 or the 4 V plateau. The capacity loss is most rapid when the cells are cycled over both plateaus. Using cells, we investigated the reasons for the cycling behavior and capacity loss with cycle number. We believe that is an excellent candidate for the cathode of the coming generation of low‐cost, high‐energy Li‐ion cells.
The injurious Effects of the Hooked Epidermal Hairs of French Beans (Phaseolus vulgaris L.) on Aphis craccivora Koch (1953)

The small, hooked epidermal hairs on french beans ( Phaseolus vulgaris ) may have a profoundly detrimental effect on colonies of Aphis craccivora . The hairs are present on the petioles, stems and undersurfaces of the leaves but are absent on the uppersurfaces of the leaves. They are most dense and therefore most injurious to the Aphids on the growing shoots. The Aphids' legs become impaled on the hooks and the results of the subsequent bleeding, starvation and exhaustion are decreased longevity and reproductive rate, high larval mortality, increased time of larval development and decreased size; this last factor is associated with a reduced fecundity. On some varieties of beans the hairs are less dense than on others and on these varieties the action of the hairs in inhibiting predators may be more important than their effect on the Aphids.
Synthesis and Tuberculostatic Activity of 2-(4,5-Disubstituted-[1,2,4] triazol-3-ylsulphanyl)-N-phenyl-acetamides (2007)

The activity of the SH group of the new 4,5-disubstituted 1,2,4-triazol-3-thiole derivatives obtained earlier1 was used in the reactions with 2-chloro-N-phenyl-acetamides. The structures of the products obtained were determined by means of 1H NMR spectroscopy and X-ray diffraction. Tuberculostatic activity of the starting triazolothioles and of their S-substituted derivatives was tested in vitro, and the minimum growth inhibiting concentration values obtained were within 12.5–100 μ g/mL.
