Glioblastoma are aggressive astrocytic brain tumours characterized by microvascular proliferation and an abnormal vasculature, giving rise to brain oedema and increased patient morbidity. Here, we have characterized the transcriptome of tumour-associated blood vessels and describe a gene signature clearly associated with pleomorphic, pathologically altered(More)
A poor response to Fas-induced apoptosis is evident in some multiple myeloma (MM) cell lines and primary cells. In this study, we have examined the possibility to increase the sensitivity to Fas-induced apoptosis by pretreatment of MM cells with interferon-gamma (IFN-gamma) or interferon-alpha (IFN-alpha). Both IFN-gamma and IFN-alpha markedly increased the(More)
Somatostatin and its analogs can inhibit growth in several cell types, in part by interfering with insulin-like growth factor-I (IGF-I) signaling. Our previous studies point to the importance of paracrine and autocrine IGF-I in the support of growth and survival of human multiple myeloma (MM) cell lines. In this report, we have investigated the potential(More)
Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma in adults. Although chemotherapy in combination with anti-CD20 antibodies results in a cure rate of 60-70 %, novel treatment approaches are warranted for the remaining patients. The insulin-like growth factor-1 receptor (IGF-1R) and its principal ligands IGF-1 and IGF-2 have been suggested to(More)
Human multiple myeloma (MM) represents a highly aneuploid tumor as shown by cytogenetic studies. This may partly explain the heterogeneity with regard to growth factor requirements demonstrated among MM cells. We have previously reported the expression of insulin-like growth factor I (IGF-I) and IGF-I receptor (IGF-IR) mRNA in some MM cell lines. In this(More)
Aberrant expression of genes regulating apoptosis/survival seems to be essential in the stepwise development of human multiple myeloma (MM). In this paper we have compared the expression of bcl-2 family pro- and anti-apoptotic genes in MM cell lines, primary MM cells and normal plasma cells. The Bcl-2, Mcl-1, Bcl-xL/S, Bcl-w, Bax, Bak, and Bad were shown to(More)
Based on successful induction of donor-specific unresponsiveness by alloantigenic stimulation in several animal models of acute rejection, we hypothesized that similar immune manipulations would also inhibit the evolution of chronic rejection and transplant vasculopathy. To induce immune tolerance, DA rats received a PVG heart allograft and were(More)
Glycosylphosphatidylinositol (GPI) is a glycolipid that tethers more than 150 different proteins to the cell surface. Aberrations in biosynthesis of GPI anchors cause congenital disorders of glycosylation with clinical features including intellectual disability (ID), seizures, and facial dysmorphism. Here, we present two siblings with ID, cerebellar(More)
OBJECTIVE Women with Lynch syndrome (LS) have up to a 60% lifetime risk of endometrial cancer (EC) and up to a 24% risk of ovarian cancer (OC). Gynecological surveillance is recommended, but the benefit and how it should be performed remain unclear. The purpose of this study was to assess diagnostic modalities for gynecological screening of LS patients in(More)
