Effects of two organotin(IV)(sulfonato phenyl)porphynates on the MAPKs and on the growth of A375 human melanoma cells
2009
Previously we showed apoptotic induction in A375 human melanoma cells using two complexes of the meso-tetra(4-sulfonatophenyl)porphinate (TPPS), (Bu 2 Sn) 2 TPPS and (Bu 3 Sn) 4 TPPS. To understand how these compounds activate apoptosis in melanoma cells we studied MAPKs and the (Bu 2 Sn) 2 TPPS and (Bu 3 Sn) 4 TPPS cellular uptake. Western blotting experiments showed activated protein kinases ERK 1/2, JNK and p38 in 10 μM (Bu 2 Sn) 2 TPPS- and 1 μM (Bu 3 Sn) 4 TPPS-treated melanoma cells, which suggests that the three MAP kinases are involved in the apoptotic death of A375-treated cells. By taking advantage of the porphyrin fluorescence, we found a fast concentration of (Bu 2 Sn) 2 TPPS an…
Cardiac and hepatic iron and ejection fraction in thalassemia major: Multicentre prospective comparison of combined Deferiprone and Deferoxamine ther…
2013
Background: Due to the limited data available in literature, the aim of this multi-centre study was to prospectively compare in thalassemia major (TM) patients the efficacy of combined deferiprone (DFP) and deferoxamine (DFO) regimen versus either DFP and DFO in monotherapy by cardiovascular magnetic resonance (CMR) over a follow up of 18 months. Methods: Among the first 1135 TM patients in the MIOT (Myocardial Iron Overload in Thalassemia) network, we evaluated those who had received either combined regimen (DFO + DFP, N=51) or DFP (N=39) and DFO (N=74) monotherapies between the two CMR scans. Iron overload was measured by T2* multiecho technique. Biventricular function parameters were qua…
