These endophenotypes are rich but not so tractable because of their worsen dimensionality, and substantial correlation, sometimes confusing causation among them. We have tried to overcome the problems inherent to biobank data, using statistical machine-learning and deep-learning technologies.Patients with mantle cell lymphoma (MCL) that fail induction treatment represent a difficult-to-treat population, where no standard therapy exists. We evaluated outcomes in patients with first relapsed-refractory (r/r) MCL after upfront high dose cytarabine including standard regimens. Overall survival (OS-2) and progression-free survival (PFS-2) were estimated from the time of salvage therapy. The previously described threshold of 24 months was used to define patients as early- or late-progressors (POD). Overall, 261 r/r MCL patients were included. Second-line regimens consisted of rituximab-bendamustine (R-B, 21%), R-B and cytarabine (R-BAC, 29%), ibrutinib (19%), and others (31%). The four groups were balanced in terms of clinicopathological features. Adjusting for age and early/late-POD, patients treated with R-BAC had significantly higher complete remission (63%) than comparators. Overall, Ibrutinib and R-BAC were associated with improved median PFS-2 [24 and 25 months, respectively], compared to R-B (13) or others (7). In patients with early-POD (n = 127), ibrutinib was associated with inferior risk of death than comparators (HR 2.41 for R-B, 2.17 for others, 2.78 for R-BAC). In patients with late-POD (n = 134), no significant differences were observed between ibrutinib and bendamustine-based treatments. Ibrutinib was associated with improved outcome in early-POD patients.Blast-phase chronic myeloid leukemia (BP-CML) is associated with additional chromosomal aberrations, RUNX1 mutations being one of the most common. Tyrosine kinase inhibitor therapy has only limited efficacy in BP-CML, and characterization of more defined molecular subtypes is warranted in order to design better treatment modalities for this poor prognosis patient group. Using whole-exome and RNA sequencing we demonstrate that PHF6 and BCORL1 mutations, IKZF1 deletions, and AID/RAG-mediated rearrangements are enriched in RUNX1mut BP-CML leading to typical mutational signature. On transcriptional level interferon and TNF signaling were deregulated in primary RUNX1mut CML cells and stem cell and B-lymphoid factors upregulated giving a rise to distinct phenotype. This was accompanied with the sensitivity of RUNX1mut blasts to CD19-CAR T cells in ex vivo assays. High-throughput drug sensitivity and resistance testing revealed leukemia cells from RUNX1mut patients to be highly responsive for mTOR-, BCL2-, and VEGFR inhibitors and glucocorticoids. These findings were further investigated and confirmed in CRISPR/Cas9-edited homozygous RUNX1-/- and heterozygous RUNX1-/mut BCR-ABL positive cell lines. Overall, our study provides insights into the pathogenic role of RUNX1 mutations and highlights personalized targeted therapy and CAR T-cell immunotherapy as potentially promising strategies for treating RUNX1mut BP-CML patients.Neurotrophins promote neuronal survival and synaptic plasticity via activating the tropomyosin receptor kinases. BDNF and its high-affinity receptor TrkB are reduced in Alzheimer's disease (AD), contributing to progressive cognitive decline. However, how the signaling mediates AD pathologies remains incompletely understood. Here we show that the TrkB receptor binds and phosphorylates APP, reducing amyloid-β production, which are abrogated by δ-secretase cleavage of TrkB in AD. Remarkably, BDNF stimulates TrkB to phosphorylate APP Y687 residue that accumulates APP in the TGN (Trans-Golgi Network) and diminishes its amyloidogenic cleavage. buy Dabrafenib Delta-secretase cleaves TrkB at N365 and N486/489 residues and abolishes its neurotrophic activity, decreasing p-APP Y687 and altering its subcellular trafficking. Notably, both TrkB and APP are robustly cleaved by δ-secretase in AD brains, accompanied by mitigated TrkB signaling and reduced p-Y687. Blockade of TrkB cleavage attenuates AD pathologies in 5xFAD mice, rescuing the learning and memory. Viral expression of TrkB 1-486 fragment in the hippocampus of APP/PS1 mice facilitates amyloid pathology and mitigates cognitive functions. Hence, δ-secretase cleaves TrkB and blunts its phosphorylation of APP, facilitating AD pathogenesis.The Editor-in-Chief and publisher have retracted this article.Radiotherapy (RT) is one of the most frequently used methods for cancer treatment. Despite remarkable advancements in RT techniquesthe treatment of radioresistant tumours (i.e. high-grade gliomas) is not yet satisfactory. Finding novel approaches less damaging for normal tissues is of utmost importance. This would make it possible to increase the dose applied to tumours, resulting in an improvement in the cure rate. Along this line, proton minibeam radiation therapy (pMBRT) is a novel strategy that allows the spatial modulation of the dose, leading to minimal damage to brain structures compared to a high dose (25 Gy in one fraction) of standard proton therapy (PT). The aim of the present study was to evaluate whether pMBRT also preserves important cerebral functions. Comprehensive longitudinal behavioural studies were performed in irradiated (peak dose of 57 Gy in one fraction) and control rats to evaluate the impact of pMBRT on motor function (motor coordination, muscular tonus, and locomotor activity), emotional function (anxiety, fear, motivation, and impulsivity), and cognitive function (learning, memory, temporal processing, and decision making). The evaluations, which were conducted over a period of 10 months, showed no significant motor or emotional dysfunction in pMBRT-irradiated rats compared with control animals. Concerning cognitive functions, similar performance was observed between the groups, although some slight learning delays might be present in some of the tests in the long term after irradiation. This study shows the minimal impact of pMBRT on the normal brain at the functional level.Conflicting results have been reported regarding which of entecavir (ETV) or tenofovir disoproxil fumarate (TDF) is associated with better outcomes. Chronic hepatitis B patients who started ETV or TDF between 2010 and 2015 were analysed. The primary outcomes were hepatocellular carcinoma and death and transplantation. The impact of the treatment on the primary outcomes was analysed using Cox proportional hazards models in the entire and propensity score-matched cohorts. A total of 404 patients (180 and 224 in the ETV and TDF groups, respectively) were analysed. The median duration of follow-up was significantly longer in the ETV group (64.0 vs. 49.1 months; P  less then  0.001). Virological response (79.4% vs. 68.4%; P = 0.018) and sustained virological suppression (59.7% vs. 45.2%; P = 0.005) were significantly higher in the TDF group. TDF was associated with lower hepatocellular carcinoma [hazard ratio (HR) 0.31, 95% confidence interval (95% CI), 0.12‒0.79; P = 0.014]; however, statistical significance was not reached after adjusting sustained virological suppression using propensity score matching (HR 0.
