Impact of early remission by induction therapy on allogeneic stem cell transplantation for acute myeloid leukemia with an intermediate risk karyotype in first complete remissionHemmati, P.G.; Terwey, T.H.; Na, I.K.; le Coutre, P.; Jehn, C.F.; Vuong, L.G.; Dörken, B.; Arnold, R. (2015)For patients with acute myeloid leukemia (AML) early achievement of remission during induction treatment is an important predictor for long-term outcome irrespective of the type of consolidation therapy employed. Here, we retrospectively examined the prognostic impact of early remission (ER) versus delayed remission (DR) in a cohort of 132 AML patients with an intermediate risk karyotype undergoing allogeneic stem cell transplantation (alloSCT) in first complete remission (CR1). In contrast t...
Phosphatidylinositol 3-Akt-kinase-dependent phosphorylation of p21(Waf1/Cip1) as a novel mechanism of neuroprotection by glucocorticoidsHarms, C.; Albrecht, K.; Harms, U.; Seidel, K.; Hauck, L.; Baldinger, T.; Huebner, D.; Kronenberg, G.; An, J.; Ruscher, K.; Meisel, A.; Dirnagl, U.; von Harsdorf, R.; Endres, M.; Hoertnagl, H. (2007)The role of glucocorticoids in the regulation of apoptosis remains incongruous. Here, we demonstrate that corticosterone protects neurons from apoptosis by a mechanism involving the cyclin-dependent kinase inhibitor p21(Waf1/Cip1). In primary cortical neurons, corticosterone leads to a dose- and Akt-kinase-dependent upregulation with enhanced phosphorylation and cytoplasmic appearance of p21(Waf1/Cip1) at Thr 145. Exposure of neurons to the neurotoxin ethylcholine aziridinium (AF64A) results ...Poulet, J.F.A.; Hedwig, B. (2003)Acoustically communicating animals are able to process external acoustic stimuli despite generating intense sounds during vocalization. We have examined how the crickets' ascending auditory pathway copes with self-generated, intense auditory signals (chirps) during singing (stridulation). We made intracellular recordings from two identified ascending auditory interneurons, ascending neuron 1 (AN1) and ascending neuron 2 (AN2), during pharmacologically elicited sonorous (two-winged), silent (o...Pfiffer, V.; Prigione, A. (2015)Assessing the bioenergetics of human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), provides considerable insight into their mitochondrial functions and cellular properties. This might allow exposing potential energetic defects caused by mitochondrial diseases. However, certain challenges have to be met due to unique growth conditions in highly specialized and costly culture media. Here, we describe a method that facilitates t...Luft, F.C. (2015)Mendelian hypertension is rare; however, Mendelian syndromes have taught us an amazing amount about mechanisms of distal sodium and chloride reabsorption, as well as how systemic hypertension might come about. In this issue of EMBO Molecular Medicine, Schumacher et al (2015) present a mouse model of the Cullin‐3 (CUL3Δ403–459) mutation, which causes a form of pseudohypoaldosteronism type‐2 (PHA‐2). CUL3 is involved in ubiquitination. Surprising is the severity of the hypertension, which may b...
