α-Catulin downregulates E-cadherin and promotes melanoma progression and invasion.

Metastasis is associated with poor prognosis for melanoma responsible for about 90% of skin cancer-related mortality. To metastasize, melanoma cells must escape keratinocyte control, invade across the basement membrane and survive in the dermis by resisting apoptosis before they can intravasate into the circulation. α-Catulin (CTNNAL1) is a cytoplasmic molecule that integrates the crosstalk between nuclear factor-kappa B and Rho signaling pathways, binds to β-catenin and increases the level of both α-catenin and β-catenin and therefore has potential effects on inflammation, apoptosis and cytoskeletal reorganization.

Endothelial cell-based methods for the detection of cyanobacterial anti-inflammatory and wound-healing promoting metabolites.

Acute lung injury is accompanied by an increased endothelial chemokine production and adhesion molecule expression, which may result in an extensive neutrophil infiltration. Moreover, a destruction of the alveolar epithelium and capillary endothelium may result in permeability edema. As such, the search for novel anti-inflammatory substances, able to downregulate these parameters as well as the tissue damage holds therapeutic promise.

Development of cellulose-DNA immunoadsorbent.

The aim of this study was to prepare a DNA immunoadsorbent for the specific, extracorporeal removal of anti-DNA antibodies from the blood of patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Two kinds of cellulose beads were applied as a carrier. Calf thymus DNA was covalently coupled to the carrier using the epichlorohydrin method.

Selective removal of circulating immune complexes from patient plasma.

The principle of a patient-specific immunoadsorber (PsIA) is demonstrated. Studies with model systems (HSA/anti-HSA) on immobilization, stability, and leakage form the basis for the presented fast-performance liquid chromatography (FPLC) and batch experiments, which were conducted using two different protein A adsorbers and autologous and heterologous PsIA systems. Experiments to determine the binding capacity of protein A adsorbers and PsIAs are described.
