It can influence both the activity and the

stability of the protein. The glycosylation pattern has been shown to depend on the cell type where the protein is expressed. We examined if differences in the glycosylation of this protein could be detected when it was expressed in the two commonly used mammalian expression systems, HEK and CHO. Differences in the glycosylation were detected. (c) 2007 Elsevier Inc. All rights reserved.”
“Most patients with acute myeloid selleck screening library leukaemia (AML) are older, with many unsuitable for conventional chemotherapy. Low-dose Ara-C (LDAC) is superior to best supportive care but is still inadequate. The combination of arsenic trioxide (ATO) and LDAC showed promise in an unrandomised study. We report a randomised trial of LDAC versus LDAC + ATO. Patients with AML according to WHO criteria Selleck RO4929097 or myelodysplastic syndrome with > 10% blasts, considered as unfit for conventional chemotherapy, were randomised between subcutaneous Ara-C (20mg b.d. for 10 days) and the same LDAC schedule with ATO (0.25 mg/kg) on days 1-5, 9 and 11, for at least four courses every 4 to 6 weeks. Overall 166 patients were entered; the trial was terminated on the advice

of the DMC, as the projected benefit was not observed. Overall 14% of patients achieved complete remission (CR) and 7% CRi. Median survival was 5.5 months and 19 months for responders (CR: not reached; CRi: 14 months; non-responders: 4 months). There were no differences in response or survival between the arms. Grade 3/4 cardiac and liver toxicity, and supportive care requirements were greater in the ATO arm. This randomised comparison demonstrates that adding ATO to LDAC provides no benefit for older patients with AML. Leukemia (2011) 25, 1122-1127; doi:10.1038/leu.2011.59; published online 8 April 2011″
“Parkinson’s Niclosamide disease (PD) is a chronic neurodegenerative disorder characterized by progressive loss of dopaminergic (DA) neurons of the substantia nigra pars compacta

with unknown aetiology. 6-Hydroxydopamine (6-OHDA) treatment of neuronal cells is an established in vivo model for mimicking the effect of oxidative stress found in PD brains. We examined the effects of 6-OHDA treatment on human neuroblastoma cells (SH-SY5Y) and primary mesencephalic cultures. Using a reverse arbitrarily primed polymerase chain reaction (RAP-PCR) approach we generated reproducible genetic fingerprints of differential expression levels in cell cultures treated with 6-OHDA. Of the resulting sequences, 23 showed considerable homology to known human coding sequences. The results of the RAP-PCR were validated by reverse transcription PCR, real-time PCR and, for selected genes, by Western blot analysis and immunofluorescence.
