Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Some infectious agents are associated with non-Hodgkin lymphoma development. Here we have used p53-deficient mice chronically injected with Streptococcus pneumoniae (Spn) with the aim to develop an animal model of infection-associated lymphomagenesis. We show that repeated stimulations with heat-killed Spn significantly enhanced the incidence of peripheral T-cell lymphoma (PTCL) in these mice. Phenotypic studies and gene expression profile analyses indicate that these PTCL arose from chronically stimulated natural killer T (NKT) cells, a T cell lineage that exhibits unique properties. Furthermore, lymphoma development was blocked when these PTCL were transferred to recipients lacking CD1d expression or treated with blocking CD1d mAbs, thus demonstrating that in vivo TCR/CD1d interactions are required for these PTCL survival. In conclusion, we have identified a new entity of peripheral T-cell lymphoma that originates from CD1d-restricted natural killer T (NKT) cells. Our results could refine the classification of PTCL and pave the way for the development of new immunotherapeutic approaches.

Description
Chemokines have been suggested to play a role during development of left ventricular failure, but little is known about their role during right ventricular (RV) remodeling and dysfunction. The first aim of this study was to identify chemokines which are regulated during RV pressure overload. We then hypothesized that these chemokines regulate SLRPs (small leucine-rich proteoglycans)

Description
Inadequate protein intake initiates an accommodative response with adverse changes in skeletal muscle function and structure. mRNA level changes due to short-term inadequate dietary protein might be an early indicator of accommodation. The aims of this study were to assess the effects of dietary protein and the diet-by-age interaction on the skeletal muscle transcript profile. Self-organizing maps were used to determine expression patterns across protein trials.
Publication Title
The skeletal muscle transcript profile reflects accommodative responses to inadequate protein intake in younger and older males.

Description
Ixodes species ticks are competent vectors of tick-borne viruses including tick-borne encephalitis and Powassan encephalitis. Tick saliva has been shown to facilitate and enhance viral infection. This likely occurs by saliva-mediated modulation of host responses into patterns favorable for viral infection and dissemination. Because of the rapid kinetics of tick-borne viral transmission, this modulation must occur as early as tick attachment and initiation of feeding. In this study, the gene expression profile of cutaneous bite-site lesions created by uninfected ticks were analyzed at 1, 3, 6, and 12 hours after Ixodes scapularis nymphal tick attachment to discover host pathways or responses potentially important in tick-borne viral establishment.

Description
In response to limited nitrogen and abundant carbon sources, diploid Saccharomyces cerevisiae strains undergo a filamentous transition in cell growth as part of pseudohyphal differentiation. Use of the disaccharide maltose as the principal carbon source, in contrast to the preferred nutrient monosaccharide glucose, has been shown to induce a hyper-filamentous growth phenotype in a strain deficient for GPA2 which codes for a Galpha protein component that interacts with the glucose-sensing receptor Gpr1p to regulate filamentous growth. In this report, we compare the global transcript and proteomic profiles of wild-type and Gpa2p deficient diploid yeast strains grown on both rich and nitrogen starved maltose media. We find that deletion of GPA2 results in significantly different transcript and protein profiles when switching from rich to nitrogen starvation media. The results are discussed with a focus on the genes associated with carbon utilization, or regulation thereof, and a model for the contribution of carbon sensing/metabolism-based signal transduction to pseudohyphal differentiation is proposed.

Transcript and proteomic analyses of wild-type and gpa2 mutant Saccharomyces cerevisiae strains suggest a role for glycolytic carbon source sensing in pseudohyphal differentiation.

Description
The CMVpp65 protein contains 2 bipartite nuclear localization signals (NLS) at 415-438aa and 537-561aa near the carboxy terminus of CMVpp65 and a phosphate binding site related to kinase activity at lysine-436. A mutation of pp65 having K436N (CMVpp65mII) and further deletion of aa537-561 resulted in a novel protein (pp65mIINLSKO) that is kinase-less and has markedly reduced nuclear localization. The purpose of this report was to study the biologic characterization of this protein and its immunogenicity compared to native pp65.Using RNA microarray analysis, expression of the CMVpp65mIINLSKO had less effect on cell cycle pathways than did the native CMVpp65 and a greater effect on cell surface signalling pathways involving immune activity. It is concluded that the removal of the primary NLS motif from pp65 does not impair its immunogenicity and may actually be advantageous in the design of a vaccine.
