Steroid withdrawal and reduction of cyclosporine A under mycophenolate mofetil after heart transplantation.

Survival and quality of life after heart transplantation are limited by a significant incidence of cardiovascular complications. Side effects of immunosuppressives contribute unfavorably. Aim of this study was to determine (1) whether withdrawal of corticosteroids and dose reduction of cyclosporine A can be performed safely under immunosuppressive therapy with mycophenolate mofetil and (2) if this is beneficial for renal function and cardiovascular risk reduction.

Sexual and relationship functioning before and after renal transplantation: a descriptive study with patients and partners.

Objective: Many patients experience problems with sexual functioning after renal transplantation (RTx). Research on the sexual functioning of the partners of those patients and the consequences for relationship satisfaction and quality of life is lacking. This study sought to explore changes in sexual and relationship functioning from before to after RTx in patients and their partners.

Customized mycophenolate dosing based on measuring inosine-monophosphate dehydrogenase activity significantly improves patients' outcomes after renal transplantation.

Background: Significant relationships have been reported between the uptake of mycophenolic acid (MPA) and the risk of acute rejection. In a prospective study after renal transplantation, we assessed the value of measuring inosine-monophosphate dehydrogenase (IMPDH) activity as a predictive indicator of an acute rejection episode in the initial postoperative period.

Patients And Methods: Fifty-two patients received 360 mg enteric-coated mycophenolate-sodium two times per day with concomitant tacrolimus/cyclosporine A, providing a total of 122 pharmacodynamic profiles.

Hypoxia inducible BHLHB2 is a novel and independent prognostic marker in pancreatic ductal adenocarcinoma.

Aims: The cyclic adenosine monophosphate-inducible basic helix-loop-helix (bHLH) domain containing class-B2 transcriptional factor BHLHB2 is differentially expressed in a number of human malignancies. In the present study, the expression, regulation, functions and prognostic impact of BHLHB2 in pancreatic cancer were investigated.

Methods: Expression analyses were carried out in tissues of the normal pancreas (n=10) and pancreatic ductal adenocarcinoma (n=77) as well as in eight pancreatic cancer cell lines using quantitative RT-PCR, semiquantitative immunohistochemistry, and immunoblot analyses.

ALCAM is associated with chemoresistance and tumor cell adhesion in pancreatic cancer.

Aims: Cell-cell adhesion is a major factor in integrity of epithelia which is frequently disturbed in cancer leading to local invasion and distant metastasis.

Methods: To define expression and function of activated leukocyte cell adhesion molecule (ALCAM, CD166) in pancreatic cancer and in pancreatic neuroendocrine tumors (PNET), microarray analyses, RT-PCR, immunohistochemistry, RNAi, adhesion, migration, invasion, and chemoresistance assays were used.

Results: We demonstrate that expression of ALCAM is altered and its serum levels are increased in pancreatic ductal adenocarcinoma (PDAC).

Successful evaluation of a new animal model using mice for esophageal adenocarcinoma.

Introduction: For the better understanding of the pathophysiological events occurring in the sequence inflammation-metaplasia-carcinoma in esophageal adenocarcinoma, an animal model would be desirable. In the past, several rat models have been used yielding conflicting results. Some demonstrated a sequence similar to the human situation whereas others failed to initiate true esophageal adenocarcinoma or even Barrett's metaplasia.

Microarray-based response prediction in esophageal adenocarcinoma.

Purpose: In locally advanced (uT(3), N(+)) adenocarcinomas of the esophagus, neoadjuvant chemotherapy improves patient outcome. However, only a subgroup of patients responds. Therefore, in the present study, we evaluated whether the response to neoadjuvant chemotherapy can be predicted by a pretreatment tumor biopsy analysis.

Peritumoral administration of GPI-anchored TIMP-1 inhibits colon carcinoma growth in Rag-2 gamma chain-deficient mice.

Exogenous application of recombinant TIMP-1 protein modified by addition of a glycosylphosphatidylinositol (GPI) anchor allows efficient insertion of the fusion protein into cell membranes. This 'cell surface engineering' leads to changes in the proteolytic environment. TIMP-1-GPI shows enhanced as well as novel in vitro biological activities including suppression of proliferation, reduced migration, and inhibition of invasion of the colon carcinoma cell line SW480.

Kinin receptors in stimulated and characterized decidua tissue-derived cells.

Bradykinin and its kinin B(2) receptor are autocrine and paracrine mediators in foetal membranes and decidua. As a first step we characterized the intracellular morphology of decidual cells. Cultured decidua tissue-derived cells immunolabel for vimentin fibrils, and are considered to be of mesenchymal origin.
