The gene expression profile of 10 primary canine insulinomas was compared with that of their accompanying metastases using microarray analysis and quantitative real time-PCR. Analysis of microarray data revealed 84 genes that were differentially expressed between primary insulinomas and their metastases, along with 243 genes differentially expressed between(More)
OBJECTIVES To describe partial pancreatectomy using a bipolar vessel-sealing device (BVSD) and compare this novel technique to the conventional suture-fracture (SF) method for canine insulinoma. METHODS Pre-, intra- and postoperative data of eight dogs with insulinoma, which underwent resection using the BVSD (LigaSure V), were prospectively collected and(More)
The establishment of reliable prognostic biomarkers for canine insulinoma are warranted to facilitate optimal patient management. Using univariate and multivariate analyses, the present study evaluated the prognostic power of several clinical and histopathological criteria, as well as the Ki67 index, in 26 dogs with insulinoma. On univariate analysis,(More)
The long-term prognosis after surgical resection of canine insulinoma is poor. Signs of hypoglycaemia often recur soon after surgery because tumour tissue has only been resected partially and/or functional (micro-)metastases were present. Using quantitative real-time PCR, the expression of 16 target genes was compared between primary canine insulinomas and(More)
The long-term prognosis after surgical resection of malignant insulinoma (INS) is poor. Novel adjuvant therapies, specifically targeting cancer stem cells (CSCs), are warranted. Therefore, the goal of this study was to characterize and target putative INS CSCs. Using fluorescence-activated cell sorting, human INS cell line CM and pancreatic carcinoid cell(More)
Epithelial cancers are defined by a tumor-specific distribution of chromosomal aneuploidies that are maintained when cells metastasize and are conserved in cell lines derived from primary tumors. Correlations between genomic copy number and gene expression have been observed for different tumors including, colorectal (CRC), breast, and pancreatic cancer.(More)
Human colorectal carcinomas are defined by a nonrandom distribution of genomic imbalances that are characteristic for this disease. Often, these imbalances affect entire chromosomes. Understanding the role of these aneuploidies for carcinogenesis is of utmost importance. Currently, established transgenic mice do not recapitulate the pathognonomic genome(More)
In this study, we generated induced pluripotent stem cells (iPSC) from normal human small airway epithelial cells (SAEC) to investigate epigenetic mechanisms of stemness and pluripotency in lung cancers. We documented key hallmarks of reprogramming in lung iPSC (Lu-iPSC) that coincided with modulation of more than 15,000 genes relative to parental SAEC. Of(More)
Tissue microarray (TMA) technology allows analysis of multiple tumour samples simultaneously on a single slide. The aim of the present study was to develop and assess a TMA containing 32 primary canine insulinomas and 13 insulinoma metastases. The results of histopathological and immunohistochemical analyses of triplicate core biopsies were compared with(More)
