Cancer specific Mucin-1 glycoforms are expressed on multiple myeloma.

Present therapies cannot cure the large majority of patients with multiple myeloma (MM) and therefore new treatment strategies are imperative. This study analysed the different glycosylation profiles of Mucin-1 (MUC1) on MM and acute myeloid leukaemia (AML) cells using a series of anti-MUC1 antibodies. Seventy-three per cent of the MM patients had plasma cells that expressed the fully glycosylated forms of MUC1.

Keratinocyte growth factor ameliorates acute graft-versus-host disease in a novel nonmyeloablative haploidentical transplantation model.

Allogeneic stem cell transplantations (SCT) are currently being used as a therapy for hematological malignancies, some solid tumors and nonmalignant bone marrow deficiencies. Nevertheless, clinical applicability is limited due to toxicity of conditioning regimens, graft-versus-host disease (GVHD) and the scarcity of HLA-identical family donors. New concepts are based on nonmyeloablative conditioning to reduce toxicity, prevention or amelioration of GVHD and the use of haploidentical donors to increase donor availability.

Mucin-1 is expressed on dendritic cells, both in vitro and in vivo.

Dendritic cells (DCs) are the best professional antigen-presenting cells to stimulate cytotoxic as well as T helper cells and are therefore appropriate candidates for establishing immunotherapy. The concept of our vaccination program is to introduce the tumor-associated antigen mucin-1 (MUC1) into DCs. Analysis of immature and mature DCs--before transducing the antigen MUC1--already demonstrated expression of MUC1 on in vitro monocyte-derived DCs upon maturation.

High expression of the HMG box factor sox-13 in arterial walls during embryonic development.

Members of the Sox gene family of transcription factors are defined by the presence of an 80 amino acid homology domain, the High Mobility Group (HMG) box. Here we report the cloning and initial analysis of murine Sox-13 . The 984 amino acids Sox-13 protein contains a single HMG box, a leucine zipper motif and a glutamine-rich stretch.
