Abstract
AIMS/HYPOTHESIS In steroid diabetes insulin secretion does not adequately compensate for enhanced hepatic gluconeogenesis and peripheral insulin resistance. Previous studies suggest that activation of the transcription factor forkhead box O1 (FOXO1) contributes to glucocorticoid-induced beta cell death. This study examines the role and regulation of FOXO1 in insulin-secreting cells. METHODS INS-1E cells and mouse islet cells were cultured in the presence of dexamethasone. Signalling pathways were modified pharmacologically or by small interfering (si)RNA-mediated inhibition of protein synthesis. Changes in protein abundance and phosphorylation were analysed by western blotting, and subcellular localisation was assessed using confocal microscopy. Transcript levels were examined by RT-PCR. RESULTS Surprisingly, downregulation of FOXO1 by siRNA did not affect dexamethasone-induced apoptosis or Bim expression, but it prevented the effects of the pan protein kinase B (AKT) inhibitor (Akti-1/2). Indeed, dexamethasone and Akti-1/2 synergistically increased beta cell death and Bim expression. Akti-1/2 triggered dephosphorylation and nuclear translocation of FOXO1. Glucocorticoid-receptor activation stimulated Foxo1 transcription, but FOXO1 phosphorylation was unchanged and the cytosolic concentration of FOXO1 remained high in relation to its nuclear concentration. However, subcellular fractionation revealed a significant increase in both cytosolic and nuclear FOXO1 compared with untreated cells. Dexamethasone diminished Pdx1 mRNA level, an effect which was not reversed by siRNA against Foxo1. Downregulation of AKT isoforms and serum/glucocorticoid-regulated kinase 1 (SGK1) suggests that only sustained suppression of all three AKT isoforms caused dephosphorylation and nuclear accumulation of FOXO1. CONCLUSIONS/INTERPRETATION This study reveals that FOXO1 is not the main mediator of glucocorticoid-receptor-induced beta cell apoptosis, but rather that it escalates beta cell death when AKT activity is inhibited by distinct pathways.

Abstract
The effects of the phototoxic K+- channel blockers 8-methoxypsoralen (8-MOP) and 5-methoxypsoralen (5-MOP) on Ranvier nodes were compared to those of 5,8-diethoxypsoralen (5,8-EOP) by means of the Hodgkin-Huxley formalism. When these test substances were added individually to the bathing solution (8-MOP: 100 micromol/l; 5-MOP: 50 micromol/l; 5,8-EOP: 10 micromol/l) the following completely reversible effects were observed: 1. 8-MOP, caused a nearly potential-independent decrease of the sodium permeability, P'Na, by ca. 17%. 5-MOP and 5,8-EOP merely decreased the maximal value of P'Na, by ca. 12 and 8% respectively, whereas with weak depolarisations P'Na was unchanged. 2. In the tested potential range the potassium permeability, P'K, was caused to decrease by ca. 9% by 8-MOP, ca. 21% by 5-MOP and ca. 19% by 5,8-EOP. 3. The potassium currents acquired a phasic time course previously described for 8-MOP and 5-MOP. They reached a relative maximum and approached a lower steady-state value, kinfinity, with a time constant tauk at V = 120 mV of about 16 ms (8-MOP), 20 ms (5-MOP) and 94 ms (5,8-EOP). To obtain dose-response relations the drug-induced effects on peak P'K and on the steady state value, kinfinity, were measured. The corresponding apparent dissociation constants (in micromol/l) were 66.6 and 80.1 (for 8-MOP), 87.6 and 25.8 (for 5-MOP), and 13.5 and 6.5 (for 5,8-EOP). In view of the similarity of the actions of 5-MOP and 5,8-EOP as well as the fact that 5,8-EOP is not phototoxic, in future 5,8-EOP may well prove to be a particularly suitable K+-channel blocker for the symptomatic therapy of multiple sclerosis and other demyelinating diseases.
