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 ...
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 ...
Efficacy of garbanzo and soybean flour in suppression of aberrant crypt foci in the colons of CF-1 mice
(2004)
Background: Epidemiological studies have reported a low incidence of colon cancer in countries with high legume consumption. Moreover, experimental studies have found that legumes, such as soybeans and pinto beans, have ...
Neural hyperplasia induced by RNA interference with m4/mα gene activity
(2000)
The E(spl) complex (E(spl)-C) contains three different classes of genes that are downstream of Notch signaling. The bHLH genes mediate the Notch signal by repressing proneural gene activity, for example during the ...
Effects of in Vivo CD8+ T cell depletion on virus replication in rhesus macaques immunized with a live, attenuated simian immunodeficiency virus vaccine
(2000)
The role of CD8+ T lymphocytes in controlling replication of live, attenuated simian immunodeficiency virus (SIV) was investigated as part of a vaccine study to examine the correlates of protection in the SIV/rhesus macaque ...
Near full-length genetic analysis of HIV sequences derived from Cyprus: Evidence of a highly polyphyletic and evolving infection
(2009)
The molecular epidemiology of HIV-1 infection was previously studied in Cyprus but the degree of HIV-1 diversity has remained indefinable. The main objective of the present study is to examine HIV-1 strains isolated from ...
The Polycomb Group Protein SUZ12 regulates histone H3 lysine 9 methylation and HP1α distribution
(2007)
Regulation of histone methylation is critical for proper gene expression and chromosome function. Suppressor of Zeste 12 (SUZ12) is a requisite member of the EED/EZH2 histone methyltransferase complexes, and is required ...
Spatially and temporally regulated α6 integrin cleavage during Xenopus laevis development
(2008)
The α6 integrin is essential for early nervous system development in Xenopus laevis. We have previously reported a uPA cleaved form of integrin α6 (α6p), in invasive human prostate cancer tissue, whose presence correlates ...
