Description
In clinical trials assessing neoadjuvant androgen deprivation therapy plus next-generation androgen receptor axis inhibitors, a subset of patients fail to demonstrate a complete pathologic response following treatment and radical prostatectomy. We performed transcriptome analyses on laser capture microdissected foci of residual tumor from these patients.

Description
Staphylococcus aureus pneumonia causes significant morbidity and mortality. Alpha-hemolysin (Hla), a pore-forming cytotoxin of S. aureus, has been identified through animal models of pneumonia as a critical virulence factor that induces lung injury. In spite of considerable molecular knowledge of how this cytotoxin injures the host, the precise host response to Hla in the context of infection remains poorly understood. We employed whole-genome expression profiling of infected lung to define the host response to wild-type S. aureus compared with an Hla-deficient isogenic mutant in experimental pneumonia. These data provide a complete expression profile at four and at twenty-four hours post-infection, revealing a unique response to the toxin-expressing strain. Gene ontogeny analysis revealed significant differences in the extracellular matrix and cardiomyopathy pathways, both of which govern cellular interactions in the tissue microenvironment. Evaluation of individual transcript responses to Hla-secreting bacteria was notable for upregulation of host cytokine and chemokine genes, including the p19 subunit of interleukin-23. Consistent with this observation, the cellular immune response to infection was characterized by a prominent TH17 response to wild-type staphylococci. These findings define specific host mRNA responses to Hla-producing S. aureus, coupling the pulmonary TH17 response to the presence of this cytotoxin. Expression profiling to define the host response to a single virulence factor proved to be a valuable tool in identifying pathways for further investigation in S. aureus pneumonia. This approach may be broadly applicable to the study of bacterial toxins, defining host pathways that can be targeted to mitigate toxin-induced disease.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Chromatin architectural protein NSBP1/HMGN5 belongs to the family of HMGN proteins which specifically interact with nucleosomes via Nucleosome Binding Domain, unfold chromatin and affect transcription. Mouse NSBP1 is a new and uncharacterized member of HMGN protein family. NSBP1 is a nuclear protein which is localized to euchromatin, binds to linker histone H1 and unfolds chromatin.
Publication Title
The interaction of NSBP1/HMGN5 with nucleosomes in euchromatin counteracts linker histone-mediated chromatin compaction and modulates transcription.

Description
Transcription factor Stat5 is constitutively active in human prostate cancer but not in normal prostate epithelium. Stat5 activation is associated with prostate cancer lesions of high histological grades, and is present in the majority of castration-resistant recurrent human prostate cancers. The molecular mechnisms underlying constitutive activation of Stat5 in primary and recurrent human prostate cancer are currently unclear.
Publication Title
Stat5 promotes metastatic behavior of human prostate cancer cells in vitro and in vivo.
