Viral infection causes activation of transcription factors NF-κB and IRF3, which collaborate to induce type I interferons (IFNs) and cellular antiviral response. Here we show that knockdown of the E3 ubiquitin ligases cIAP1 and cIAP2 markedly inhibited virus-triggered activation of IRF3 and NF-κB as well as IFN-β induction. Knockdown of cIAP1 and cIAP2 also inhibited cytoplasmic dsRNA-triggered cellular antiviral response. Endogenous coimmunoprecipitation experiments indicated that viral infection caused recruitment of cIAP1 and cIAP2 to TRAF3, TRAF6, and VISA. Furthermore, we demonstrated that cIAP1- and cIAP2-mediated virus-triggered ubiquitination of TRAF3 and TRAF6. These findings suggest that virus-triggered ubiquitination of TRAF3 and …

BACKGROUND: Antimicrobial lock therapy (ALT) may be considered as adjunctive therapy in the treatment of catheter-related bloodstream infections (CRBSI) when catheter removal is not a favorable option. OBJECTIVE: To evaluate the outcomes associated with ALT as adjunctive treatment of CRBSI. METHODS: This was a 24-month retrospective case series analysis evaluating patients treated for more than 24 hours with ALT. The primary outcome was blood culture sterilization for 30 days posttherapy. The impact of ALT duration and time to initiation on central venous catheter (CVC) salvage were evaluated. Logistic regression modeled the association between ALT and sterilization rates, with a prespecified …

INTRODUCTION: Hospital patients recovering from critical illness on general floors often receive insulin therapy based on protocols designed for patients admitted directly to general floors. The objective of this study is to compare glycemic control and insulin dosing in patients recovering from critical illness and those without prior critical illness. METHODS: Medical record review of blood glucose measurements and insulin dosing in 25 patients under general ward care while transitioning from the intensive care unit (transition group) and 25 patients admitted directly to the floor (direct floor group). RESULTS: Average blood glucose did not differ significantly between groups (transition group …

Longevity in humans is determined by multiple environmental and genetic factors. We have investigated possible associations between longevity and Single Nucleotide Polymorphisms (SNPs) in the p21 (CDKN1A) gene, a stress-inducible senescence-associated cell cycle inhibitor, expression of which upregulates genes implicated in several age-related diseases. By sequencing the promoter and exons of p21 in genomic DNA of ten individuals over 90 years old, we have identified 30 SNPs, many of which had not been previously characterized. A cluster of minor alleles within the -4547/-3489 bp region did not alter the basal activity or p53 responsiveness of the p21 promoter. We then …

BACKGROUND: RNA interference (RNAi) mediated by small interfering RNAs (siRNAs) or short hairpin RNAs (shRNAs) has become a powerful technique for eukaryotic gene knockdown. siRNA GC-content negatively correlates with RNAi efficiency, and it is of interest to have a convincing mechanistic interpretation of this observation. We here examine this issue by considering the secondary structures for both the target messenger RNA (mRNA) and the siRNA guide strand. RESULTS: By analyzing a unique homogeneous data set of 101 shRNAs targeted to 100 endogenous human genes, we find that: 1) target site accessibility is more important than GC-content for efficient RNAi; 2) …

The proliferative lifespan of normal somatic human cells in culture terminates in a permanent growth-arrested state known as replicative senescence. In this study, we show that RNA interference-mediated repression of the genes encoding the small ubiquitin-related modifier (SUMO)-specific proteases, Senp1, Senp2, and Senp7, induced low passage primary human fibroblasts to senesce rapidly. Following Senp1 repression, we observed a global increase in sumoylated proteins and in the number and size of nuclear SUMO-containing promyelocytic leukemia (PML) bodies. SUMO/PML bodies also increased during replicative senescence. p53 transcriptional activity was enhanced towards known p53 target genes following repression of Senp1, and inhibition of …
