The Rab11-family interacting protein 3 (Rab11-FIP3), also known as Arfophilin and Eferin, is a Rab11 and ADP-ribosylation factor (ARF) binding protein of unknown function. Here, we sought to investigate the subcellular localisation and elucidate the function of Rab11-FIP3 in eukaryotic membrane trafficking. Utilising a polyclonal antibody specific for(More)
Erythrocytes have a defined lifespan in vivo, and the signals that maintain their survival in circulation or trigger their death are unknown. Here, we investigated the control of erythrocyte survival and death in an in vitro culture system where erythrocytes survived for 10 days in serum-free medium in the presence or absence of bovine serum. Death of the(More)
BACKGROUND This small, pilot study evaluated the impact of treatment with a natural multi-mineral supplement from seaweed (Aquamin) on walking distance, pain and joint mobility in subjects with moderate to severe osteoarthritis of the knee. METHODS Subjects (n = 70) with moderate to severe osteoarthritis of the knee were randomized to four double-blinded(More)
Hereditary Hemochromatosis is an iron overload disease most frequently associated with mutations in the HFE gene. While clinical studies of the disease have received extensive attention by various groups, the localisation, trafficking and function of the HFE protein, and its chaperone beta2-microglobulin (beta2M), require further investigation. In this(More)
Yeast Saccharomyces cerevisiae contains two genes, RAS1 and RAS2, which show remarkable homology to mammalian ras genes. To characterize these gene products, we have expressed the RAS2 gene in yeast using an inducible GAL10 promoter. After labeling with [35S]methionine and immunoprecipitating with a monoclonal antibody Y13-259, which reacts with p21 encoded(More)
