Implementation of back to living well, a community-based program for the tertiary prevention of low back pain: a study protocol.

Background: The current literature supports the effectiveness of exercise, education, and self-management interventions for the long-term management of persistent low back pain. However, there is significant uncertainty about the implementation of interventions related to barriers, facilitators, and patient's preferences. This study will evaluate the Back to Living Well program implementation from a participant and organizational perspective.

BET inhibitors as a therapeutic intervention in gastrointestinal gene signature-positive castration-resistant prostate cancer.

Unlabelled: A subgroup of castration-resistant prostate cancer (CRPC) aberrantly expresses a gastrointestinal (GI) transcriptome governed by two GI-lineage-restricted transcription factors, HNF1A and HNF4G. In this study, we found that expression of GI transcriptome in CRPC correlates with adverse clinical outcomes to androgen receptor signaling inhibitor treatment and shorter overall survival. Bromo- and extra-terminal domain inhibitors (BETi) downregulated HNF1A, HNF4G, and the GI transcriptome in multiple CRPC models, including cell lines, patient-derived organoids, and patient-derived xenografts, while AR and the androgen-dependent transcriptome were largely spared.

Cognitive functional therapy with or without movement sensor biofeedback versus usual care for chronic, disabling low back pain (RESTORE): a randomised, controlled, three-arm, parallel group, phase 3, clinical trial.

Background: Low back pain is the leading cause of years lived with disability globally, but most interventions have only short-lasting, small to moderate effects. Cognitive functional therapy (CFT) is an individualised approach that targets unhelpful pain-related cognitions, emotions, and behaviours that contribute to pain and disability. Movement sensor biofeedback might enhance treatment effects.

Design and Synthesis of LM146, a Potent Inhibitor of PB1 with an Improved Selectivity Profile over SMARCA2.

PB1 is a bromodomain-containing protein hypothesized to act as the nucleosome-recognition subunit of the PBAF complex. Although PB1 is a key component of the PBAF chromatin remodeling complex, its exact role has not been elucidated due to the lack of potent and selective inhibitors. Chemical probes that target specific bromodomains within the complex would constitute highly valuable tools to characterize the function and therapeutic pertinence of PB1 and of each of its bromodomains.

BET Bromodomain Inhibition Blocks an AR-Repressed, E2F1-Activated Treatment-Emergent Neuroendocrine Prostate Cancer Lineage Plasticity Program.

Purpose: Lineage plasticity in prostate cancer-most commonly exemplified by loss of androgen receptor (AR) signaling and a switch from a luminal to alternate differentiation program-is now recognized as a treatment resistance mechanism. Lineage plasticity is a spectrum, but neuroendocrine prostate cancer (NEPC) is the most virulent example. Currently, there are limited treatments for NEPC.

Prevention strategies to reduce future impact of low back pain: a systematic review and meta-analysis.

Objective: To evaluate the evidence from randomised controlled trials (RCTs) on the effectiveness of prevention strategies to reduce future impact of low back pain (LBP), where impact is measured by LBP intensity and associated disability.

Design: Systematic review with meta-analysis.

Data Sources: MEDLINE, Embase, CINAHL, PEDro and The Cochrane (CENTRAL) databases from inception to 22 October 2018.

RESTORE-Cognitive functional therapy with or without movement sensor biofeedback versus usual care for chronic, disabling low back pain: study protocol for a randomised controlled trial.

Introduction: Low back pain (LBP) is the leading cause of disability globally and its costs exceed those of cancer and diabetes combined. Recent evidence suggests that individualised cognitive and movement rehabilitation combined with lifestyle advice (cognitive functional therapy (CFT)) may produce larger and more sustained effects than traditional approaches, and movement sensor biofeedback may enhance outcomes. Therefore, this three-arm randomised controlled trial (RCT) aims to compare the clinical effectiveness and economic efficiency of individualised CFT delivered with or without movement sensor biofeedback, with usual care for patients with chronic, disabling LBP.

RVX-297, a BET Bromodomain Inhibitor, Has Therapeutic Effects in Preclinical Models of Acute Inflammation and Autoimmune Disease.

Bromodomain (BD) and extra-terminal domain containing proteins (BET) are chromatin adapters that bind acetylated histone marks via two tandem BDs, BD1 and BD2, to regulate gene transcription. BET proteins are involved in transcriptional reprogramming in response to inflammatory stimuli. BET BD inhibitors (BETis) that are nonselective for BD1 or BD2 have recognized anti-inflammatory properties in vitro and counter pathology in models of inflammation or autoimmune disease.

A novel BET bromodomain inhibitor, RVX-208, shows reduction of atherosclerosis in hyperlipidemic ApoE deficient mice.

Despite the benefit of statins in reducing cardiovascular risk, a sizable proportion of patients still remain at risk. Since HDL reduces CVD risk through a process that involves formation of pre-beta particles that facilitates the removal of cholesterol from the lipid-laden macrophages in the arteries, inducing pre-beta particles, may reduce the risk of CVD. A novel BET bromodomain antagonist, RVX-208, was reported to raise apoA-I and increase preβ-HDL particles in non-human primates and humans.

RVX-208, an inducer of ApoA-I in humans, is a BET bromodomain antagonist.

Increased synthesis of Apolipoprotein A-I (ApoA-I) and HDL is believed to provide a new approach to treating atherosclerosis through the stimulation of reverse cholesterol transport. RVX-208 increases the production of ApoA-I in hepatocytes in vitro, and in vivo in monkeys and humans, which results in increased HDL-C, but the molecular target was not previously reported. Using binding assays and X-ray crystallography, we now show that RVX-208 selectively binds to bromodomains of the BET (Bromodomain and Extra Terminal) family, competing for a site bound by the endogenous ligand, acetylated lysine, and that this accounts for its pharmacological activity.

Ephrin A5 expression promotes invasion and transformation of murine fibroblasts.

Emerging evidence suggests involvement of the ephrin/Eph receptor system in tumourigenesis. Research on this new role has centred on the contribution of Eph receptors. In contrast, we focused on the elucidation of the role of ephrins, specifically ephrin A5.

Integrin-linked kinase activity regulates Rac- and Cdc42-mediated actin cytoskeleton reorganization via alpha-PIX.

Cell spreading and migration are regulated in a Rho family GTPase-dependent manner by growth factors and integrin-mediated cell-extracellular matrix (ECM) interactions. The molecular mechanisms involved in the ECM- and growth factor-mediated activation of these small GTPases remain unclear. In the present study, we demonstrate that integrin-linked kinase (ILK), which is a focal adhesion protein activated by both ECM and growth factors, is required for the activation of Rac and Cdc42 in epithelial cells.

Integration of cell attachment, cytoskeletal localization, and signaling by integrin-linked kinase (ILK), CH-ILKBP, and the tumor suppressor PTEN.

Cell attachment and the assembly of cytoskeletal and signaling complexes downstream of integrins are intimately linked and coordinated. Although many intracellular proteins have been implicated in these processes, a new paradigm is emerging from biochemical and genetic studies that implicates integrin-linked kinase (ILK) and its interacting proteins, such as CH-ILKBP (alpha-parvin), paxillin, and PINCH in coupling integrins to the actin cytoskeleton and signaling complexes. Genetic studies in Drosophila, Caenorhabditis elegans, and mice point to an essential role of ILK as an adaptor protein in mediating integrin-dependent cell attachment and cytoskeletal organization.

Regulation of protein kinase B/Akt-serine 473 phosphorylation by integrin-linked kinase: critical roles for kinase activity and amino acids arginine 211 and serine 343.

Protein kinase B (PKB/Akt) is a regulator of cell survival and apoptosis. To become fully activated, PKB/Akt requires phosphorylation at two sites, threonine 308 and serine 473, in a phosphatidylinositol (PI) 3-kinase-dependent manner. The kinase responsible for phosphorylation of threonine 308 is the PI 3-kinase-dependent kinase-1 (PDK-1), whereas phosphorylation of serine 473 has been suggested to be regulated by PKB/Akt autophosphorylation in a PDK-1-dependent manner.

The integrin-linked kinase (ILK) suppresses anoikis.

Disruption of integrin-extracellular matrix interactions in normal epithelial cells induces apoptosis, a process termed anoikis. Reduced sensitivity to anoikis appears to be an important hallmark of oncogenic transformation, particularly in the process of metastasis. Several pathways have been implicated in the suppression of anoikis, however, the events which take place proximal to the integrin receptors remain unclear.

Inhibition of integrin-linked kinase (ILK) suppresses activation of protein kinase B/Akt and induces cell cycle arrest and apoptosis of PTEN-mutant prostate cancer cells.

PTEN is a tumor suppressor gene located on chromosome 10q23 that encodes a protein and phospholipid phosphatase. Somatic mutations of PTEN are found in a number of human malignancies, and loss of expression, or mutational inactivation of PTEN, leads to the constitutive activation of protein kinase B (PKB)/Akt via enhanced phosphorylation of Thr-308 and Ser-473. We recently have demonstrated that the integrin-linked kinase (ILK) can phosphorylate PKB/Akt on Ser-473 in a phosphoinositide phospholipid-dependent manner.
