Transforming growth factor β (TGFβ) is a pleiotropic protein secreted from essentially all cell types and primary tissues. While TGFβ’s actions reflect the activity of a number of signaling networks, the primary mediator of TGFβ responses are the Smad proteins. Following receptor activation, these cytoplasmic proteins form hetero-oligomeric complexes that translocate to the nucleus and affect gene transcription. Here, through biological, biochemical, and immunofluorescence approaches, sorting nexin 9 (SNX9) is identified as being required for Smad3-dependent responses. SNX9 interacts with phosphorylated (p) Smad3 independent of Smad2 or Smad4 and promotes more rapid nuclear delivery than that observed independent of ligand. Although SNX9 does not bind nucleoporins Nup153 or Nup214 or some β importins (Imp7 or Impβ), it mediates the association of pSmad3 with Imp8 and the nuclear membrane. This facilitates nuclear translocation of pSmad3 but not SNX9.

Abstract These guidelines are intended for use by infectious disease specialists, orthopedic surgeons, neurosurgeons, radiologists, and other healthcare professionals who care for patients with native vertebral osteomyelitis (NVO). They include evidence and opinion-based recommendations for the diagnosis and management of patients with NVO treated with antimicrobial therapy, with or without surgical intervention.

Abstract Background: Unnecessary intervention and overtreatment of indolent disease are common challenges in clinical management of prostate cancer. Improved tools to distinguish lethal from indolent disease are critical. Methods: We performed a genome-wide survival analysis of cause-specific death in 24,023 prostate cancer patients (3,513 disease-specific deaths) from the PRACTICAL and BPC3 consortia. Top findings were assessed for replication in a Norwegian cohort (CONOR). Results: We observed no significant association between genetic variants and prostate cancer survival. Conclusions: Common genetic variants with large impact on prostate cancer survival were not observed in this study. Impact: Future studies should be designed for identification of rare variants with large effect sizes or common variants with small effect sizes.

PurposeWilson's disease is a rare autosomal recessive genetic disorder that results in accumulation of copper in the liver, brain, cornea and kidney. Therapeutic plasma exchange (TPE) has been used to remove copper and provide a bridge to liver transplantation. We report here the collective experiences through the ASFA apheresis registry on Wilson's disease.MethodsThe ASFA apheresis registry is a multi‐center registry study. Both prospective and retrospective data, with the latter involving data collection back to January 2000 are entered in the registry. The registry includes patient demographics, apheresis procedural information, treatment schedules, and treatment outcomes and complications.ResultsA total of 10 patients (3 males and 7 females) with Wilson's disease treated between 2005 and 2013 were included. Median age of first diagnosis and first TPE were 16 and 17 years, respectively. Via central venous access, these patients underwent a total of 43 TPEs; the median number of TPE procedures per patient was 3.5. All of the TPEs used ACD‐A as anticoagulation, 42/43 TPEs targeted 1–1.25 plasma volumes, and 41/43 TPEs were performed with 100% fluid balance. Post TPE procedures, 9 patients underwent liver transplantation; all 10 patients had at least a 6‐month survival.ConclusionsAll 10 patients with Wilson's disease who underwent TPE had a positive outcome in terms of 6‐month survival. In this first report of the ASFA apheresis registry study, we have demonstrated the value of using this registry to collect apheresis‐related patient outcomes from multiple centers. J. Clin.
