The Drosophila Ash1 protein is a trithorax-group (trxG) regulator that antagonizes Polycomb repression at HOX genes. Ash1 di-methylates lysine 36 in histone H3 (H3K36me2) but how this activity is controlled and at which genes it functions is not well understood. We show that Ash1 protein purified from Drosophila exists in a complex with MRG15 and Caf1 that we named AMC. In Drosophila and human AMC, MRG15 binds a conserved FxLP motif near the Ash1 SET domain and stimulates H3K36 di-methylation on nucleosomes...

Nanoparticles create exciting platforms for anticancer immunotherapy and vaccination, though their inherent immunomodulatory properties have remained underexploited. Ammonio methacrylate copolymers (AMC) are well-established excipients in pharmaceutical industry and components of controlled-release oral formulations. Here, we demonstrate that nanoscaling of type A and B AMC (Eudragit® RL and RS) endows these inactive ingredients immunostimulatory properties exploitable for cancer therapy. The particles induce the secretion of various pro-inflammatory cytokines and chemokines from the cells of innate immunity...

BACKGROUND: Acute mechanical circulatory support (aMCS) can be a lifesaving therapy for patients with refractory cardiogenic shock. As device safety and technology improve, so will the ability to extend aMCS to patients at remote hospitals. The Intermountain West is unique because of the large geographical area, making transport of critically ill patients a logistical challenge. METHODS: We reviewed our experience of transporting patients in cardiogenic shock over long distances who had already been placed on aMCS: Impella and extracorporeal membrane oxygenator devices...

Since 2006 the Australian Medical Council (AMC) accreditation standards have required medical schools to comprehensively address issues related to the health of Aboriginal and Torres Strait Islander peoples in Australia, and Māori in New Zealand. This has spanned areas of staff expertise, staff and student recruitment, curriculum and institutional leadership. These Indigenous specific standards have, until now, been absent for specialist medical college accreditation. The AMC revised its accreditation standards for specialist medical colleges in 2015, and for the first time included Indigenous specific standards...

Mutations of cystic fibrosis transmembrane conductance regulator (CFTR) cause cystic fibrosis (CF) with a multitude of clinical manifestations. Some CF patients develop clinically significant anemia, suggesting that CFTR may regulate hematopoiesis. Here, we report that cftr mutant zebrafish model exhibits primitive and definitive hematopoietic defects with impaired Wnt signaling. Cftr is found to interact, via its PDZ-binding domain (PDZBD), with Dishevelled (Dvl), a key component of Wnt signaling required for hematopoietic progenitor specification, thus protecting Dvl from Dapper1 (Dpr1)-induced lysosomal degradation...

While the promise of the Human Genome Project provided significant insights into the structure of the human genome, the complexities of disease at the individual level have made it difficult to utilize -omic information in clinical decision making. Some of the existing constraints have been minimized by technological advancements that have reduced the cost of sequencing to a rate far in excess of Moore's Law (a halving in cost per unit output every 18 months). The reduction in sequencing costs has made it economically feasible to create large data commons capturing the diversity of disease across populations...

Kex2 is the prototype of a large family of eukaryotic subtilisin-related proprotein-processing proteases that cleave at sites containing pairs of basic residues. Here, we studied the effects of KCl on the individual rate constants of association, dissociation, acylation and deacylation and determined the thermodynamic parameters at each step of the Kex2 reaction. Potassium bound Kex2 with KD=20.3mM. The order in which potassium entered the reaction system modified the effect of activation or inhibition, which depended on the size of the substrate...
