Transposition is one of the primary mechanisms causing genome instability. This phenomenon is mechanistically related to other DNA rearrangements such as V(D)J recombination and retroviral DNA integration. In the Tn5 system, only one protein, the transposase (Tnp), is required for all of the catalytic steps involved in transposon movement. The complexity involved in moving multiple DNA strands ...

The effect of the potent angiogenesis inhibitor O-(chloroacetyl-carbamoyl)fumagillol (TNP-470), a semisynthetic analogue of fumagillin, on tumor growth and metastasis was studied using rodent tumors. Injection of TNP-470 s.c. inhibited tumor growth in a dose-dependent manner, and the tumor sizes of B16BL6 melanoma, M5076 reticulum cell sarcoma, Lewis lung carcinoma, and Walker 256 carcinoma wer...

The capacity of the trinitrophenyl (TNP) haptenic group, coupled to a series of chemically dissimilar carriers, to cross-stimulate putative T- dependent and T-independent murine B-cell subpepulations was determined by using an in vitro limiting dilution technique to generate primary IgM responses. It was found that TNP-Ficoll and TNP-dextran, two T- independent antigens with little or no polycl...

BACKGROUND Topical negative pressure (TNP), widely used in wound therapy, is known to stimulate wound edge blood flow, granulation tissue formation, angiogenesis, and revascularization. We have previously shown that application of a TNP of -50 mmHg to the myocardium significantly increases microvascular blood flow in the underlying tissue. We have also shown that a myocardial TNP levels between...

In Bošković (2008a) I argue that there is a fundamental structural difference in the traditional Noun Phrase (TNP) of English and article-less languages like SC, which can be captured if DP is not even present in the TNPs in (2) (see also Fukui 1988, Corver 1992, Zlatić 1997, Chierchia 1998, Cheng and Sybesma 1999, Lyons 1999, Willim 2000, Baker 2003, among others for no-DP analyses of at least...

The technique of antigen-driven, 5-bromo-deoxyuridine and light suicide has been adapted to eliminate the precursors of cytotoxic effector cells both for alloantigen and for 2,4,6-trinitrophenyl(TNP)-modified stimulator and target cells. Using this technique, the following observations have been made. Precursors of killer cells specific for alloantigen can be suicided independently of precursor...

Methionine aminopeptidase-2 (MetAP2) is over-expressed in several cancers, including the cholangiocarcinoma (CCA). We reported previously suppressive effects of fumagillin, a MetAP2 inhibitor, on growth of CCA cell lines. In the present study, we evaluated the anti-proliferative and anti-invasive activities of TNP-470, a fumagillin analogue with higher MetAP2 inhibitory activity, on CCA cell li...

The above observations demonstrated induction of immunological tolerance in vitro in primed IgD-, IgG+ B cells. In these studies, addition of trinitrophenylated (TNP) turkey gammaglobulin (TGG) or TNP ovalbumin conjugates suppressed the secondary in vitro response in mice primed with TNP keyhole limpet hemocyanin (TNP-KLH). Suppression was not a reflection of a shift in kinetics of the antibody...

Tn5 transposase (Tnp) overproduction is lethal to Escherichia coli. Tnp overproduction causes cell filamentation, abnormal chromosome segregation, and an increase in anucleated cell formation. There are two simple explanations for the observed phenotype: induction of the SOS response or of the heat shock response. The data presented here show that overproduction of Tnp neither induces an SOS re...

TNP-ATP has become widely recognized as a potent and selective P2X receptor antagonist, and is currently being used to discriminate between subtypes of P2X receptors in a variety of tissues. We have investigated the ability of TNP-ATP to inhibit alpha,beta-methylene ATP (alpha,beta-meATP)-evoked responses in 1321N1 human astrocytoma cells expressing recombinant rat or human P2X(2/3) receptors. ...
