Project description:Mouse bone marrow-derived macrophages (BMDM) grown in macrophage colony-stimulating factor (CSF-1) have been used widely in studies of macrophage biology and the response to toll-like receptor agonists. We investigated whether similar cells could be derived from the domestic pig. Cultivation of pig bone marrow cells for 5-7 days in presence of rhCSF-1 generated a pure population of BMDM that expressed the usual macrophage markers (CD14, CD16, CD163, CD172a), are potent phagocytic cells and produced tumor necrosis factor (TNF) in response to lipopolysaccharide (LPS). Bone marrow cells could be stored frozen and thawed, providing a renewable resource. We profiled gene expression in pig BMDM from outbred animals (Large-White Landrace F1cross) responding to LPS using Affymetrix microarrays. The temporal cascade of inducible and repressible genes more closely-resembled human than mouse macrophages, and included genes involved in tryptophan metabolism (IDO, KYN), lymphoattractant chemokines (CCL20) and the vitamin D3-converting enzyme Cyp27B1. Conversely, pig BMDM, like human macrophages, did not induce genes involved in arginine metabolism, nor did they produce nitric oxide. The data establish pig BMDM as an alternative tractable model for the study of macrophage transcriptional control.

Project description:This time course analysis is to study the targets and functions of miR-124. MiR-124 was overexpressed and the effect of miR-124 overexpression was compared to negative controls to identify downregulated genes and potential miRNA targets. Keywords: time course

Project description:This phase I trial studies how well an imaging agent called I-124 M5A works in detecting CEA-positive colorectal cancer that has spread to the liver. I-124 M5A is a monoclonal antibody, called M5A, linked to a radioactive substance called I-124. M5A binds to CEA-positive cancer cells and may, through imaging scans, be able to detect liver metastases by picking up signals from I-124.

The data establish pig BMDM as an alternative tractable model for the study of macrophage transcriptional control. RNA for gene expression analysis was collected at time points 0, 2, 7 and 24 hours post LPS stimulation (100ng/ml). Each time point included BMDM from the same three pigs and each cell culture was replicated. The replicate of the pig3_24h was not suitable for RNA analysis. Therefore, a total of 23 microarrays were hybridized.

Project description:Laparoscopic surgery of the distal colon and rectum requires surgery with an appropriate field of view. A commonly used technique to create a clear exposure is the steep Trendelenburg position in which the patient is positioned in an angle of 15 to 40 degrees with the head down using the effect of gravity to retract the small intestine. This method is associated with haemostatic changes caused by the cranial shift of abdominal organs and blood. Recently, a cellulose compressed sponge was developed as intraoperative retractor, with the aim to keep the small intestines aside while the patient remains in a horizontal position. The safety of the sponge is secured with CE marking. The retractor sponge ensures a clear surgical field and potentially prevents haemostatic instability by avoiding Trendelenburg position. A pilot study in the St Antonius Hospital Nieuwegein has shown that use of the sponge might be associated with shorter hospital stay.

Project description:miRNA sponge, a special class of miRNA target, has been emerging as a pivotal player in miRNA mediated regulatory network. Currently, the identified miRNA sponge genes mostly act on sequestering conserved miRNAs (e.g. miR-7, miR-145), however, the existence, potential function and evolutionary process of miRNA sponge genes for species-specific miRNA, especially for human specific miRNA, are largely unknown. In this study, we conducted a systematic analysis including sponge gene identification and subsequent function and evolutionary analyses for an authentic human-specific miRNA, miR-941.
