BACKGROUND: Docetaxel is the only FDA-approved first-line treatment for castration-resistant prostate cancer (CRPC) patients. Docetaxel treatment inevitably leads to tumour recurrence after an initial therapeutic response with generation of multinucleated polyploid (MP) cells. Here we investigated role of MP cells in clinical relapse of CRPC. METHODS: Prostate cancer (PC-3) cells were treated with docetaxel (5 nM) for 3 days followed by a washout and samples were collected at close intervals over 35 days post drug washout...

BACKGROUND: Stathmin1 (STMN1) is a cytosolic phosphoprotein that regulates cellular microtubule dynamics and is known to have oncogenic activity. Despite several reports, its roles in gastric cancer (GC) remain unclear owing to a lack of analyses of highly metastatic cases. This study aimed to investigate STMN1 as a prognostic and predictive indicator of response to paclitaxel therapy in patients with GC, including inoperable cases. METHODS: Immunohistochemical analysis of STMN1 was performed on both operable (n=95) and inoperable GC (n=61) samples...

We performed a nested case-control study in a cohort of antihypertensive drug users to assess the association between discontinuation of different antihypertensive agents and the risk of acute myocardial infarction (AMI). Cases and controls were drawn from the Utrecht Cardiovascular Pharmacogenetics database. Patients who were hospitalised for their first AMI were considered cases and controls were not hospitalised for AMI. Antihypertensive users were defined as current users if the index date (date of AMI) fell within the prescribed duration or as discontinuers if this date fell outside the prescribed duration...

Leukemias bearing CRLF2 and JAK2 gene alterations are characterized by aberrant JAK/STAT signaling and poor prognosis. The HDAC inhibitor givinostat/ITF2357 has been shown to exert antineoplastic activity against both systemic juvenile idiopathic arthritis and myeloproliferative neoplasms through inhibition of the JAK/STAT pathway. These findings led us to hypothesize that givinostat might also act against CRLF2-rearranged BCP-ALL, which lack effective therapies. Here, we found that givinostat inhibited proliferation and induced apoptosis of BCP-ALL CRLF2-rearranged cell lines, positive for exon 16 JAK2 mutations...

Sleep-wake disturbances following traumatic brain injury (TBI) are increasingly recognized as a serious consequence following injury and as a barrier to recovery. Injury-induced sleep-wake disturbances can persist for years, often impairing quality of life. Recently, there has been a nearly exponential increase in the number of primary research articles published on the pathophysiology and mechanisms underlying sleep-wake disturbances after TBI, both in animal models and human subjects, including in the pediatric population...

Suppression of undesirable emotions, as well as beliefs about the unacceptability of experiencing and expressing emotions, have both been shown to be related to poorer health-related outcomes in several clinical groups. Potential models through which these variables relate have yet to be tested in those with irritable bowel syndrome (IBS) and are therefore examined in the current article. Online questionnaires were administered to people with IBS (n = 84) to test a mediation model in which beliefs about the unacceptability of emotions are associated with greater emotional suppression, which in turn relates to increased affective distress and consequently poorer quality of life...

BACKGROUND: Computer-delivered cognitive behavioural therapy (cCBT) is an effective alternative to provider-delivered treatment for depression and anxiety, but high attrition poses a significant challenge to its use. Peer support is a feasible approach to improving cCBT engagement, but less is known about its acceptability among Veterans. AIMS: To obtain feedback from Veterans (n = 24) with depression and/or anxiety on their preferences for (a) activities of Veterans Administration Peer Support Specialists (VA PSS) in helping Veterans use Moving Forward, a cCBT-based protocol developed by VA, and (b) methods for delivering support to Veterans using this programme...

REVIEW
M A Soliman, F Aboharb, N Zeltner, L Studer
Neuropsychiatric disorders place an enormous medical burden on patients across all social and economic ranks. The current understanding of the molecular and cellular causes of neuropsychiatric disease remains limited, which leads to a lack of targeted therapies. Human-induced pluripotent stem cell (iPSC) technology offers a novel platform for modeling the genetic contribution to mental disorders and yields access to patient-specific cells for drug discovery and personalized medicine. Here, we review recent progress in using iPSC technology to model and potentially treat neuropsychiatric disorders by focusing on the most prevalent conditions in psychiatry, including depression, anxiety disorders, bipolar disorder and schizophrenia...

Depression is a leading cause of disability worldwide and a major contributor to the burden of suicide. A major limitation of classical antidepressants is that 2-4 weeks of continuous treatment is required to elicit therapeutic effects, prolonging the period of depression, disability and suicide risk. Therefore, the development of fast-onset antidepressants is crucial. Preclinical identification of fast-onset antidepressants requires animal models that can accurately predict the delay to therapeutic onset. Although several well-validated assay models exist that predict antidepressant potential, few thoroughly tested animal models exist that can detect therapeutic onset...

Therapy-related acute promyelocytic leukemia (t-APL) is relatively rare, with limited data on outcome after treatment with arsenic trioxide (ATO) compared to standard intensive chemotherapy (CTX). We evaluated 103 adult t-APL patients undergoing treatment with all-trans retinoic acid (ATRA) alone (n=7) or in combination with ATO (n=24), CTX (n=53), or both (n=19). Complete remissions were achieved after induction therapy in 57% with ATRA, 100% with ATO/ATRA, 78% with CTX/ATRA, and 95% with CTX/ATO/ATRA. Early death rates were 43% for ATRA, 0% for ATO/ATRA, 12% for CTX/ATRA, and 5% for CTX/ATO/ATRA...

Recurrent chromosomal abnormalities and gene mutations detected at the time of diagnosis of acute myeloid leukemia (AML) are associated with particular disease features, treatment response and survival of AML patients, and are used to denote specific disease entities in the World Health Organization classification of myeloid neoplasms and acute leukemia. However, large studies that integrate cytogenetic and comprehensive mutational information are scarce. We created a comprehensive oncoprint of mutations associated with recurrent cytogenetic findings by combining the information on mutational patterns of 80 cancer- and leukemia-associated genes with cytogenetic findings in 1603 adult patients with de novo AML...
