Insulin-mimetic action of vanadium compounds on osteoblast-like cells in culture
(1997)
Vanadium compounds mimic insulin actions in different cell types. The present study concerns the insulin-like effects of three vanadium(V) derivatives and one vanadium(IV) complex on osteoblast-like (UMR106 and MC3T3E1) ...
A spiking neuron model: Applications and learning
(2002)
This paper presents a biologically inspired, hardware-realisable spiking neuron model, which we call the Temporal Noisy-Leaky Integrator (TNLI). The dynamic applications of the model as well as its applications in Computational ...
Identification of a potent activator of Akt phosphorylation from a novel series of phenolic, picolinic, pyridino, and hydroxamic zinc(II) complexes
(2011)
The discovery of small-molecule modulators of signaling pathways is currently a particularly active area of research. We aimed at developing unprecedented metal-based activators of Akt signaling which can potentially find ...
Profiling early infection responses: Pseudomonas aeruginosa eludes host defenses by suppressing antimocrobial peptide gene expression
(2005)
Insights into the host factors and mechanisms mediating the primary host responses after pathogen presentation remain limited, due in part to the complexity and genetic intractability of host systems. Here, we employ the ...
Groucho mediates a Ci-independent mechanism of hedgehog repression in the anterior wing pouch
(2001)
Groucho (Gro) is the founding member of a family of transcriptional co-repressors that are recruited by a number of different transcription factors. Drosophila has a single gro gene, whose loss of function affects processes ...
Arginine methylation at histone H3R2 controls deposition of H3K4 trimethylation
(2007)
Modifications on histones control important biological processes through their effects on chromatin structure. Methylation at lysine 4 on histone H3 (H3K4) is found at the 5′ end of active genes and contributes to ...
Quantitative analysis of serum neutralization of human immunodeficiency virus type 1 from subtypes A, B, C, D, E, F, and I: Lack of direct correlation between neutralization serotypes and genetic subtypes and evidence for prevalent serum-dependent infectivity enhancement
(1996)
Human immunodeficiency virus type 1 (HIV-1) M group strains have been assigned to date to nine distinct genetic subtypes, designated A through I, according to phylogenetic analyses of nucleotide sequences of their env or ...
Exploiting position effects and the gypsy retrovirus insulator to engineer precisely expressed transgenes
(2008)
A major obstacle to creating precisely expressed transgenes lies in the epigenetic effects of the host chromatin that surrounds them. Here we present a strategy to overcome this problem, employing a Gal4-inducible luciferase ...
Structure-activity relationships of brassinin in preventing the development of carcinogen-induced mammary lesions in organ culture
(1994)
Brassinin, a pkytoalexin, is found in Chinese cabbage. Previously, we showed that brassinin significantly inhibited dimethylbenz(a)anthracene (DMBA)-induced mammary lesions in organ culture. Moreover, it was an effective ...
