The cGMP-dependent protein kinase G-1α (PKG-1α) is a downstream mediator of nitric oxide and natriuretic peptide signaling. Alterations in this pathway play a key role in the pathogenesis and progression of vascular diseases associated with increased vascular tone and thickness, such as pulmonary hypertension. Previous studies have shown that tyrosine… (More)
Prostate cancer (PCa) like other tumors expresses antigens that may serve as target for specific immunotherapy. Special antigen-presenting cells (e. g., dendritic cells) are capable of generating tumor-specific immunity. Cytotoxic T-cells (killer cells) are very effective against antigens and, consequently, against the respective tissue or tumor. Cancer… (More)
The development of pulmonary hypertension (PH) involves the uncontrolled proliferation of pulmonary smooth muscle cells via increased growth factor receptor signaling. However, the role of epidermal growth factor receptor (EGFR) signaling is controversial, as humans with advanced PH exhibit no changes in EGFR protein levels and purpose of the present study… (More)
Rare Epstein-Barr virus (EBV)+ smooth muscle tumours (SMT) manifest typically under immunosuppression. Three major subtypes are known: human immunodeficiency virus-associated (HIV-SMT), after transplantation (PTSMT) or associated with congenital immunodeficiency syndromes (CI-SMT). So far, there are no analyses which compare the clinico-pathological… (More)
Epstein-Barr virus (EBV)-associated post-transplant smooth muscle tumours (PTSMT), are rare complications following organ/stem cell transplantation. Despite the mainly benign behaviour of PTSMT, alternative therapies are needed for those patients with progressive tumours. In tumours not approachable by surgery or reduction of immunosuppression, the… (More)
This report presents current work and results of projects in the uro-oncological field from the Cantonal Hospital of St. Gallen. The first part deals with dendritic cell-based immunotherapy of hormone refractory prostate cancer. In the second part, some recent results of clinical and laboratory work for non-muscle invasive bladder cancer are highlighted.
