Basal autophagy is pivotal for Hodgkin and Reed-Sternberg cells' survival and growth revealing a new strategy for Hodgkin lymphoma treatment.

As current classical Hodgkin lymphoma (cHL) treatment strategies have pronounced side-effects, specific inhibition of signaling pathways may offer novel strategies in cHL therapy. Basal autophagy, a regulated catabolic pathway to degrade cell's own components, is in cancer linked with both, tumor suppression or promotion. The finding that basal autophagy enhances tumor cell survival would thus lead to immediately testable strategies for novel therapies.

Hodgkin and Reed-Sternberg cells of classical Hodgkin lymphoma are highly dependent on oxidative phosphorylation.

The metabolic properties of lymphomas derived from germinal center (GC) B cells have important implications for therapeutic strategies. In this study, we have compared metabolic features of Hodgkin-Reed-Sternberg (HRS) cells, the tumor cells of classical Hodgkin's lymphoma (cHL), one of the most frequent (post-)GC-derived B-cell lymphomas, with their normal GC B cell counterparts. We found that the ratio of oxidative to nonoxidative energy conversion was clearly shifted toward oxidative phosphorylation (OXPHOS)-linked ATP synthesis in HRS cells as compared to GC B cells.

COX-2-dependent and potentially cardioprotective effects of negative inotropic substances released after ischemia.

During reperfusion, cardiodepressive factors are released from isolated rat hearts after ischemia. The present study analyzes the mechanisms by which these substances mediate their cardiodepressive effect. After 10 min of global stop-flow ischemia, rat hearts were reperfused and coronary effluent was collected over a period of 30 s.

Immunoadsorption in dilated cardiomyopathy: 6-month results from a randomized study.

Background: Various randomized studies evidenced that immunoadsorption (IA) repeated at monthly intervals induced acute and prolonged hemodynamic benefit in patients with severe heart failure due to dilated cardiomyopathy. Some findings indicate that the use of only one course of IA therapy may also induce prolonged beneficial effects.

Methods: This randomized study included 22 patients suffering from severe heart failure (left ventricular ejection fraction [LVEF] <35%) due to dilated cardiomyopathy.

Effects of immunoadsorption on the nt-BNP and nt-ANP plasma levels of patients suffering from dilated cardiomyopathy.

Immunoadsorption (IA) represents an additional therapeutic approach in patients with severe heart failure due to dilated cardiomyopathy (DCM). nt-BNP and nt-ANP plasma levels are prognostic markers in patients with heart failure. The effect of IA on nt-BNP and nt-ANP plasma levels is unknown.
