Affymetrix Rat Expression 230A Array (rae230a)
Description
Previous studies have shown that treatment with the somatostatin analogue octreotide LAR causes regression of gastric ECL-cell carcinoids in patients with hypergastrinaemia due to chronic atrophic gastritis, reducing both the number and size of tumours. The main objective of the present study was to examine the molecular mechanisms behind the antiproliferative effect of octreotide in the oxyntic mucosa on a genome wide scale. Female Sprague-Dawley rats were dosed with octreotide LAR and control group were given the LAR vehicle for 21 days. Serum gastrin levels were measured and tissue samples for histology and RNA extraction collected from the oxyntic mucosa. Histomorphological examination showed a significant decrease in the number of gastric glands, cells per gland and length of glands, indicating a negative effect of octreotide on growth of the oxyntic mucosa. Further immunohistochemical studies showed a tendency towards increased apoptosis and decreased proliferation in the group receiving octreotide. Affymetrix GeneChip microarrays were used to detect differentially expressed genes. Many regulated genes could be related to regulation of apoptosis, fewer to proliferation, and the largest group of regulated genes was transcriptional factors several of which may be involved in regulation of growth. Control studies using quantitative real-time RT-PCR showed a high degree of consistency of the microarray results. In conclusion, octreotide exerts a negative effect on growth of the oxyntic mucosa, and extensive gene expression changes relevant to growth regulation can be detected.

Description
Our study demonstrates that neutrophils infiltrate early-stage PTEN-deficient uterine tumors and oppose tumor growth and malignant progression by inducing detachment and ultimately promoting cell death of tumor cells. This RNA-seq study examined the expression profiles of these uterine epithelial tumor cells in the presence versus absence of neutrophil infiltration. Overall design: Tumor cells from 4-week-old tumor-bearing neutrophil-sufficient versus -deficient mice were isolated by fluorescence activated cell sorting, RNA was isolated, and expression profiles were analyzed by deep sequencing.

Description
Patients with systemic lupus erythematosus (SLE) have a markedly increased risk to develop cardiovascular disease, and traditional cardiovascular risk factors fail to account for this increased risk. We used microarray to probe the platelet transcriptome in individuals with SLE and healthy controls, and the gene and protein expression of a subset of differentially expressed genes was further investigated and correlated to platelet activation status. Real-time PCR was used to confirm a type I interferon (IFN) gene signature in patients with SLE, and the IFN-regulated proteins PRKRA, IFITM1 and CD69 (p<0.0001) were found to be up-regulated in platelets from SLE patients as compared to healthy volunteers. Notably, patients with a history of vascular disease had increased expression of type I IFN-regulated proteins as well as more activated platelets as compared with patients without vascular disease. We suggest that interferogenic immune complexes stimulate production of IFN which up-regulates the megakaryocytic type I IFN-regulated genes and proteins. This could affect platelet activation and contribute to development of vascular disease in SLE. In addition, platelets with type I IFN signature could be a novel marker for vascular disease in SLE.
