Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Due to the urgent need of new targeting strategies in PCa, AR interacting proteins should be considered. In this study we aimed to test the effect of a long-term knockdown of NCOA1, an AR coactivator, in PCa progression and metastatogenesis and whether NCOA1 could be used as a possible therapeutic target. To test the consequences of NCOA1 knockdown on proliferation, we performed by 3H thymidine incorporation assays revealing a strong reduction in castration resistant MDA PCa 2b and androgen-dependent LNCaP cells, without affecting AR negative PC3 cells. Furthermore, Boyden chamber assays revealed a strong decrease in migration and invasion upon NCOA1 knockdown. Using a cDNA microarray, we identified protein kinase D1 (PRKD1) as one prominent upregulated gene in MDA PCa 2b, which was not seen in PC3 cells. Knockdown of PRKD1 clearly reverted the reduced migratory potential. Moreover, we found phospholipase A2, group7 (PLA2G7) and eukaryotic translation initiation factor 5A2 (EIF5A2), which might be involved in migration of PC3 cells. Further, we can clearly demonstrate that PRKD1 is negatively regulated by the AR/NCOA1 complex. In addition, immunhistochemical staining revealed a strong increase in NCOA1 expression in matched and unmatched patients samples, respectively between normal prostate and primary tumor. Regarding the PRKD1 staining, no final conclusion can be drawn in terms of a tumor suppressor function. Thus, our findings directly associate NCOA1/AR complex with PRKD1 regulation and further suggest NCOA1 as a potential therapeutic target also due to the effect on PC3 cell migration.

Pseudomonas aeruginosa is a common bacterium in the terminal plumbing system of buildings and it is from this niche that a substantial fraction of infections are acquired. To better understand P. aeruginosa biology in this environment, we examined the transcriptomes in tap water and pond water.

Description
HutchinsonGilford progeria syndrome (HGPS) is a rare genetic disease with widespread phenotypic features resembling premature aging. HGPS was recently shown to be caused by dominant mutations in the LMNA gene, resulting in the in-frame deletion of 50 amino acids near the carboxyl terminus of the encoded lamin A protein. Children with this disease typically succumb to myocardial infarction or stroke caused by severe atherosclerosis at an average age of 13 years. To elucidate further the molecular

Description
The type II Oncostatin M receptor (OSMR) serves as the main binding site for the pleiotropic cytokine OSM. We have previously demonstrated a positive correlation between copy number driven OSMR over-expression and adverse clinical outcome in cervical tumours and have also established enhanced angiogenic, migratory and invasive potential as major consequences of OSMR over-expression using cell-line models of cervical cancer. By analysis of gene expression patterns in cell lines and tumours, this study now systematically defines cohorts of genes that are implicated for the phenotypes observed. Importantly, we have identified 15 OSM induced genes that are involved in at least one of these key functions and are up-regulated in both OSMR over-expressing cell-lines and tumours. These genes can serve as markers of OSM signalling in OSMR over-expressing SCCs and represent suitable targets for functional characterisation.

Overexpression of the oncostatin M receptor in cervical squamous cell carcinoma cells is associated with a pro-angiogenic phenotype and increased cell motility and invasiveness.

RNA sequencing on LNCaP cells was carried out to study how tunicamycin-induced gene expression is affected by knockdown of EIF2AK3 and ATF4. Overall design: Samples from the below setup (treatments protocol) were harvested from four independent experiments. RNA integrity of total RNA samples was assessed by Bioanalyzer. All samples had RIN = 9.7.

Description
Background & Aims: Spasmolytic polypeptide/TFF2-expressing metaplasia (SPEM) is known to emerge following parietal cell loss and during Helicobacter pylori infection, however its role in gastric ulcer repair is unknown. Therefore, we sought to investigate if SPEM plays a role in epithelial regeneration. Methods: Acetic acid ulcers were induced in young (2-3 months) C57BL/6 mice to determine the quality of ulcer repair. Gastric tissue was collected and analyzed to determine the expression of SPEM within the regenerating epithelium. As a comparison to native tissue the expression of SPEM was also identified within cultured gastric mouse-derived organoids. Results: Wound healing in the mice coincided with the emergence of SPEM expressing CD44v within the ulcerated region. The emergence of SPEM was also observed in cultured gastric organoids. Conclusions: These data demonstrate the SPEM may play a role in epithelial regeneration. Conclusions: These data demonstrate the SPEM may play a role in epithelial regeneration. Overall design: 4 samples were used for ulcerated and uninjured tissue. 1 sample was used for intact tissue and organoid-derived RNA. The 'Ulcerated' samples represent C57BL/6 mice with ulcers and the 'Uninjured' samples represent the healthy controls (for "ulcerated" samples). The "Intact stomach tissue" and "Gastric organoids" samples are other types of samples that compared separately. "Gastric organoids" in this comparison are derived from "Intact stomach tissue".

Description
The motor neurons innervating the muscles of facial expression are organized into somatotopic hindbrain clusters termed subnuclei. Each of the medial, intermediate, dorsolateral, and lateral subnuclei gives rise to a specific branch of the facial motor nerve (cranial nerve VII). How subnucleus-specific gene expression could mediate the accurate development of facial nerve projections was not well understood.
