Chromatography has become an indispensable tool for the purification of proteins. Since the regulatory demands on protein purity are expected to become stricter, the need for generating improved resins for chromatographic separations has increased. More advanced scientific investigations of protein structure/function relationships, in particular, have also been a driving force ...

The t(10;11)(p12;q23) translocation and the t(10;11)(p12;q14) translocation, which encode the MLL (mixed lineage leukemia)-AF10 and CALM (clathrin assembly lymphoid myeloid leukemia)-AF10 fusion oncoproteins, respectively, are two recurrent chromosomal rearrangements observed in patients with acute myeloid leukemia and acute lymphoblastic leukemia. Here, we demonstrate that MLL-AF10 and CALM-AF10-mediated transformation is dependent ...

Beneficial effects of prebiotics like inulin and fructo-oligosaccharides (FOS) have been proven in health and nutrition. Yacon (Smallanthus sonchifolius), an Andean crop, contains FOS (50-70 % of its dry weight) and, therefore, is considered a prebiotic. Commercial FOS can up-regulate total secretory IgA (S-IgA) in infant mice, prevent infection with Salmonella ...

Cyclophilins catalyze the reversible peptidyl-prolyl isomerization of their substrates and are present across all kingdoms of life from humans to bacteria. Although numerous biological roles have now been discovered for cyclophilins, their function was initially ascribed to their chaperone-like activity in protein folding where they catalyze the often rate-limiting step ...

Present interferon-based therapy for chronic hepatitis C (CHC) is limited by both efficacy and tolerability. Telaprevir and boceprevir are the first two direct acting antiviral drugs (DAAs) which inhibit HCV replication to be licensed for use, in conjunction with pegylated interferon and ribavirin. Numerous other DAAs are in clinical development, ...
