Tumor necrosis factor (TNF) is a pro-inflammatory cytokine that controls expression of inflammatory genetic networks. Although the nuclear factor-kappaB (NF-kappaB) pathway is crucial for mediating cellular TNF responses, the complete spectrum of NF-kappaB-dependent genes is unknown. In this study, we used a tetracycline-regulated cell line expressing an NF-kappaB inhibitor to systematically identify NF-kappaB-dependent genes. A microarray data set generated from a time course of TNF stimulation in the presence or absence of NF-kappaB signaling was analyzed. We identified 50 unique genes that were regulated by TNF (Pr(F)<0.001) and demonstrated a change in signal intensity of+/-3-fold relative to control. Of these, 28 were NF-kappaB-dependent, encoding proteins involved in diverse cellular activities. Quantitative real-time PCR assays of eight characterized NF-kappaB-dependent genes and five genes not previously known to be NF-kappaB-dependent (Gro-beta and-gamma, IkappaBepsilon, interleukin (IL)-7R, and Naf-1) were used to determine whether they were directly or indirectly NF-kappaB regulated. Expression of constitutively active enhanced green fluorescent.NF-kappaB/Rel A fusion protein transactivated all but IL-6 and IL-7R in the absence of TNF stimulation. Moreover, TNF strongly induced all 12 genes in the absence of new protein synthesis. High probability NF-kappaB sites in novel genes were predicted by binding site analysis and confirmed by electrophoretic mobility shift assay. Chromatin immunoprecipitation assays show the endogenous IkappaBalpha/epsilon, Gro-beta/gamma, and Naf-1 promoters directly bound NF-kappaB/Rel A in TNF-stimulated cells. Together, these studies systematically identify the direct NF-kappaB-dependent gene network downstream of TNF signaling, extending our knowledge of biological processes regulated by this pathway. 相似文献

BackgroundStroke is a leading cause of disability and distress, and often profoundly affects the quality of life of stroke survivors and their carers. With the support of carers, many stroke survivors are returning to live in the community despite the presence of disability and ongoing challenges. The sudden and catastrophic changes caused by stroke affects the mental, emotional and social health of both stroke survivors and carers. The aim of this study is to evaluate a Stroke and Carer Optimal Health Program (SCOHP) that adopts a person-centred approach and engages collaborative therapy to educate, support and improve the psychosocial health of stroke survivors and their carers.MethodsThis study is a prospective randomised controlled trial. It will include a total of 168 stroke survivors and carers randomly allocated into an intervention group (SCOHP) or a control group (usual care). Participants randomised to the intervention group will receive nine (8 + 1 booster) sessions guided by a structured workbook. The primary outcome measures for stroke survivors and carers will be health-related quality of life (AQoL-6D and EQ-5D) and self-efficacy (GSE). Secondary outcome measures will include: anxiety and depression (HADS); coping (Brief COPE); work and social adjustment (WSAS); carer strain (MCSI); carer satisfaction (CASI); and treatment evaluation (TEI-SF and CEQ). Process evaluation and a health economic cost analysis will also be conducted.DiscussionWe believe that this is an innovative intervention that engages the stroke survivor and carer and will be significant in improving the psychosocial health, increasing independence and reducing treatment-related costs in this vulnerable patient-carer dyad. In addition, we expect that the intervention will assist carers and stroke survivors to negotiate the complexity of health services across the trajectory of care and provide practical skills to improve self-management.

People living with severe mental illness (SMI) are one of the most marginalized groups in society. Interventions which aim to improve their social and economic participation are of crucial importance to clinicians, policy‐makers and people with SMI themselves. We conducted a systematic review of the literature on social interventions for people with SMI published since 2016 and collated our findings through narrative synthesis. We found an encouragingly large amount of research in this field, and 72 papers met our inclusion criteria. Over half reported on the effectiveness of interventions delivered at the service level (supported accommodation, education or employment), while the remainder targeted individuals directly (community participation, family interventions, peer‐led/supported interventions, social skills training). We identified good evidence for the Housing First model of supported accommodation, for the Individual Placement and Support model of supported employment, and for family psychoeducation, with the caveat that a range of models are nonetheless required to meet the varied housing, employment and family‐related needs of individuals. Our findings also highlighted the importance of contextual factors and the need to make local adaptations when “importing” interventions from elsewhere. We found that augmentation strategies to enhance the effectiveness of social interventions (particularly supported employment and social skills training) by addressing cognitive impairments did not lead to transferable “real life” skills despite improvements in cognitive function. We also identified an emerging evidence base for peer‐led/supported interventions, recovery colleges and other interventions to support community participation. We concluded that social interventions have considerable benefits but are arguably the most complex in the mental health field, and require multi‐level stakeholder commitment and investment for successful implementation. 相似文献
