Burkitt lymphoma (BL) has a high mortality rate and its treatment is currently limited to chemotherapy combined with immunotherapy. The long non‑coding RNA antisense non‑coding RNA in the INK4 locus (ANRIL) has been identified as an oncogene that can regulate cell proliferation and apoptosis in multiple types of cancer. However, the function of ANRIL in BL remains unknown. The present study aimed to determine the effect of ANRIL on cell proliferation and apoptosis in BL. Reverse transcription‑quantitative PCR was used to analyze the expression levels of ANRIL in BL cells. The effect of ANRIL knockdown on BL cells was determined using Cell Counting Kit‑8, flow cytometric, western blotting, immunofluorescence staining and Hoechst staining assays. The results revealed that ANRIL silencing inhibited the proliferation and promoted the apoptosis of BL cells. In addition, the expression levels of cyclin D1, E2F transcription factor 1 and Bcl‑2 were downregulated, while the expression levels of cyclin‑dependent kinase inhibitor 1A, Bcl‑2‑associated X protein, cleaved‑caspase‑9/pro‑caspase‑9 and cleaved‑caspase‑3/pro‑caspase‑3 were upregulated. Furthermore, the knockdown of ANRIL activated the TGF‑β1 signaling pathway, as evidenced by the upregulated expression levels of TGF‑β1, phosphorylated (p)‑SMAD2/3/SMAD2/3, p‑SMAD1/SMAD1 and sphingosine‑1‑phosphate receptor 2. Moreover, the protective effect of ANRIL silencing in BL could be inhibited by the TGF‑β receptor type I/II dual inhibitor, LY2109761. In conclusion, the findings of the present study suggested that the knockdown of ANRIL may inhibit cell proliferation and promote cell apoptosis in BL by regulating the TGF‑β1 signaling pathway, which may provide a novel target for the treatment of BL.The incidence of allergic rhinitis (AR) is increasing worldwide. Human nasal epithelial cells (HNECs) are the key cells in the occurrence of AR. Antisense non-coding RNA in the INK4 locus (ANRIL) was discovered to be involved in the progression of AR. However, the mechanism by which ANRIL mediates the progression of AR remains to be determined. The present study aimed to further explore the mechanism by which ANRIL regulates AR. Thereby, HNECs were treated with IL-13 to mimic AR in vitro. The mRNA expression levels of ANRIL, microRNA (miR)-15a-5p, JAK2, mucin 5AC (MUC5AC), granulocyte-macrophage colony-stimulating factor (GM-CSF) and eotaxin-1, and protein expression levels of JAK2, STAT3 and phosphorylated-STAT3 in HNECs were analyzed using reverse transcription-quantitative PCR and western blotting, respectively. ELISAs were used to detect the secretory levels of inflammatory cytokines and mucin in cell supernatants. In addition, a dual luciferase reporter assay was used to confirm the downstream target of e miR-15a-5p/JAK2 axis. selleckchem Thus, ANRIL may serve as a novel target for AR treatment.

To explore the prognostic value of pre-specified comorbidities on treatment outcomes in PsA, and to compare baseline data with cutaneous psoriasis without arthritis and healthy controls (HC).

Patients initiating conventional synthetic/biological disease-modifying antirheumatic drugs were enrolled in this clinical observational cohort study, and data on comorbidities, and clinical and patient-reported outcomes were retrieved at baseline and after 4 months. Pearson's chi-squared tests were performed to investigate the prognostic value of pre-specified comorbidities and achievement of ACR20, DAPSA50 and MDA. Mann-Whitney U tests were used to compare OMERACT PsA Core Outcome Set (COS) measures at baseline and follow-up for the pre-specified comorbidities.

A total of 100 PsA patients were included at baseline. Statistically significantly fewer patients with obesity achieved DAPSA50 compared with patients without obesity (P=0.035), and fewer patients with hypertension (P=0.034) and Charlson Comorbidity Index (CCI) ≥1 (P=0.027), respectively, achieved MDA compared with patients without these comorbidities. Patients with obesity, hypertension, widespread pain, and CCI ≥1 had significantly worse COS measures at follow-up compared with patients without these comorbidities. At baseline, patients with PsA had higher disease burden compared with patients with cutaneous psoriasis and HC, including higher pain (P<0.001) and fatigue (P<0.001) scores, and more widespread pain (P=0.002).

Obesity, hypertension and CCI ≥1 were prognostic factors for poorer treatment outcome rates in PsA. Pain and fatigue were more frequently reported among patients with PsA compared with patients with cutaneous psoriasis and HC.

The Danish National Committee on Health Research Ethics H-15009080; Data Protection Agency 2012-58-0004; ClinicalTrials.gov NCT02572700.Aldehyde dehydrogenases (ALDHs) catalyze the conversion of various aliphatic and aromatic aldehydes into corresponding carboxylic acids. Traditionally considered as housekeeping enzymes, new biochemical roles are being identified for members of ALDH family. Recent work showed that AldA from the plant pathogen Pseudomonas syringae strain PtoDC3000 (PtoDC3000) functions as an indole-3-acetaldehyde dehydrogenase for the synthesis of indole-3-acetic acid (IAA). IAA produced by AldA allows the pathogen to suppress salicylic acid-mediated defenses in the model plant Arabidopsis thaliana. Here we present a biochemical and structural analysis of the AldA indole-3-acetaldehyde dehydrogenase from PtoDC3000. Site-directed mutants targeting the catalytic residues Cys302 and Glu267 resulted in a loss of enzymatic activity. The X-ray crystal structure of the catalytically inactive AldA C302A mutant in complex with IAA and NAD+ showed the cofactor adopting a conformation that differs from the previously reported structure of AldA. These structures suggest that NAD+ undergoes a conformational change during the AldA reaction mechanism similar to that reported for human ALDH. Site-directed mutagenesis of the IAA binding site indicates that changes in the active site surface reduces AldA activity; however, substitution of Phe169 with a tryptophan altered the substrate selectivity of the mutant to prefer octanal. The present study highlights the inherent biochemical versatility of members of the ALDH enzyme superfamily in P. syringae.

Rheumatoid arthritis (RA) and osteoarthritis (OA) are two major types of joint diseases. The present study aimed to identify hub genes involved in the pathogenesis and further explore the potential treatment targets of RA and OA.

The gene expression profile of GSE12021 was downloaded from Gene Expression Omnibus (GEO). Total 31 samples (12 RA, 10 OA and 9 NC samples) were used. The differentially expressed genes (DEGs) in RA versus NC, OA versus NC and RA versus OA groups were screened using limma package. We also verified the DEGs in GSE55235 and GSE100786. link2 Functional annotation and protein-protein interaction (PPI) network construction of OA- and RA-specific DEGs were performed. Finally, the candidate small molecules as potential drugs to treat RA and OA were predicted in CMap database.

165 up-regulated and 163 down-regulated DEGs between RA and NC samples, 73 up-regulated and 293 down-regulated DEGs between OA and NC samples, 92 up-regulated and 98 down-regulated DEGs between RA and OA samples were identified. Immune response and TNF signaling pathway were significantly enriched pathways for RA- and OA-specific DEGs, respectively. The hub genes were mainly associated with 'Primary immunodeficiency' (RA vs. NC group), 'Ribosome' (OA vs. link3 NC group), and 'Chemokine signaling pathway' (RA vs. OA group). Arecoline and Cefamandole were the most promising small molecule to reverse the RA and OA gene expression.

Our findings suggest new insights into the underlying pathogenesis of RA and OA, which may improve the diagnosis and treatment of these intractable chronic diseases.

Although, for some members of the disability community, the option to engage with telehealth may result in reduced barriers to care, for others, inadequate attention to the design, implementation, and policy dimensions may be detrimental. Addressing such considerations is imperative to mitigate health inequities faced by the disability community.

Several factors are known to impact response to the intensive interdisciplinary pain treatment (IIPT) program described in this study, yet no research has explored the role of perfectionism. This secondary data analysis explored direct and indirect relations between perfectionism and functional disability (primary outcome) and pain severity (secondary outcome) after IIPT, with pain catastrophizing and fear of pain as mediators.

Youth (N = 253) aged 8-21 with chronic pain and associated disability completed pre- and post-IIPT measures of self-oriented perfectionism (SOP), socially prescribed perfectionism (SPP), pain catastrophizing, fear of pain, functional disability, and pain characteristics for routine clinical care and this nonrandomized trial. Eight mediated models were run for the two predictors, two mediators, and two outcomes.

Pretreatment perfectionism (SOP and SPP) led to greater reductions in pain catastrophizing over the course of IIPT, which resulted in lower pain severity (β = -.02 [CI = -0.07, -0.01] for SOP and β = -.02 [CI = -0.06, -0.003] for SPP) and less functional disability (β = -.06 [CI = -0.13, -0.01] for SOP and β = -.06 [CI = -0.14, -0.01] for SPP). Independent of pain catastrophizing, pretreatment SPP was directly associated with more posttreatment functional disability (β = .16 [CI = 0.05, 0.27]). Fear of pain was not a mediator.

Findings suggest perfectionism has the potential to negatively impact IIPT outcomes. However, when perfectionistic youth with chronic pain learn to manage pain-related distress, they benefit. Results highlight the importance of assessing for and treating perfectionism and pain-related distress in youth with chronic pain.

The adoption of research evidence to improve client outcomes may be enhanced using the principles of implementation science. This systematic review aimed to understand the effect of involving consumers to change health professional behaviours and practices. The barriers and enablers to consumer engagement will also be examined.

We searched Medline, CINAHL, Embase, the Cochrane Central Register of Controlled Trials and PDQ-Evidence from 2004 to February 2019. Implementation studies involving consumers in at least one phase (development, intervention or facilitation) of an intervention that aimed to change health professional behaviour to align with evidence-based practice were included. Studies in the areas of paediatrics and primary care were excluded. Two review authors independently screened studies for inclusion, and one author extracted data and conducted quality assessments with review of a second author. Knowledge translation interventions were categorized using the Effective Practice and Organisation of Care taxonomy.
