(Submitter supplied) Background: In aging and Alzheimer’s disease there are striking changes in CSF composition that may relate to altered choroid plexus function. Studying CP tissue gene expression at the BCSFB provides further insight into epithelial and stromal responses to aging and diseased states. Results: Highly significant differences in gene expression occurred in CP of advanced AD patients vs. normal controls. more...

(Submitter supplied) We profiled genome-wide gene expression in nasal scrapes following grass pollen challenge and Prednisone treatment. It was a randomized, double-blind, placebo-controlled, three-period, cross-over trial to evaluate the effects of single oral doses of 10 mg and 25 mg of prednisone on inflammatory mediators measured in nasal exudates after nasal allergen challenge in susceptible individuals with allergic rhinitis. more...

(Submitter supplied) This is a quality control (QC) substudy of GSE48091. The QC substudy comprises gene-expression profiling of re-extracted tumor RNA for a subset of the tumours in the full study. As background, a population-based cohort study of metastatic breast cancer patients was first designed. Thereafter, a case-control study nested in the corresponding population-based cohort of primary breast cancer patients was designed by selecting distant metastasis-free controls to each case. more...

(Submitter supplied) The purpose of this study was to improve prediction of patients at high-risk for metastatic disease utilizing a nested case-control design that uniquely enables enrichment for relevant phenotypes. We identified all women diagnosed with primary breast cancer from January 1, 1997, to December 31, 2005, in the Stockholm health care region. Patients developing distant metastatic disease (cases) were selected and controls (free from distant disease) were randomly matched by adjuvant therapy, age and calendar period at diagnosis. more...

(Submitter supplied) To determine whether breast cancer molecular subtypes and tumor characteristics with demonstrated significance in a primary tumor setting can also confer clinically relevant information in breast cancer metastases. We assessed previously published gene expression modules of seven biological processes and the intrinsic subtypes (PAM50). The translational aspect of the Swedish randomized TEX trial included 112 patients with at least one biopsy from morphologically confirmed loco-regional or distant breast cancer metastasis diagnosed from December 2002 until June 2007. more...

Blood draws every 4 hours during a 3-day study: 24-hour normal baseline, 38 hours of continuous wakefulness and subsequent recovery sleep, for a total of 19 time-points per subject, with every 2-hr psychomotor vigilance test (PVT) assessment when awake. more...

(Submitter supplied) Approximately 30% of rheumatoid arthritis patients achieve inadequate response to anti-TNF biologics. In this study, we sought to identify a blood gene expression biomarker correlating with 12-week response to infliximab in patients with moderate to severe disease. Response was assessed using dynamic contrast-enhanced MRI imaging of the wrist.

(Submitter supplied) Breast cancer molecular subtypes preferentially metastasize to specific organs and the anatomical location of the metastasis is associated with the length of survival post-recurrence. We used microarrays to provide a detailed characterization of breast cancer site-specific metastases with particular focus on identifying genes predictive of breast cancer liver metastatic proprnsity

(Submitter supplied) In this study, we examined the impact of modulating the TGF-β/PAI-1 axis in CD34+ cells function from diabetic patients and controls. Using gene array studies, we found that diabetics, protected from microvascular complications despite suboptimal glycemic control, had reduced level of TGF- β1 and PAI-1 transcripts in their CD34+ cells compared to age, sex, duration and degree of glycemic control -matched diabetics with microvascular complications. more...

(Submitter supplied) microRNAs are ∼22 nucleotide regulatory RNAs that are processed into duplexes from hairpin structures and incorporated into Argonaute proteins. We find that a nick in the middle of the guide strand of an miRNA sequence allows for seed-based targeting characteristic of miRNA activity. Insertion of an inverted abasic, a dye, or a small gap between the two segments still permits target knockdown. While activity from the seed region of the segmented miRNA is apparent, activity from the 3' half of the guide strand is impaired, suggesting that an intact guide backbone is required for contribution from the 3' half. more...

(Submitter supplied) In addition to silencing intended target genes, transfected siRNAs regulate numerous unintended transcripts through a mechanism in which the equivalent of a microRNA-like seed region in the siRNA recognizes complementary sequences in transcript 3' UTRs. The ability to limit such off-target effects would substantially facilitate accurate interpretation of RNA interference (RNAi) experiments and thus greatly enhance their value. more...
