  1. 1. New Approaches to Studies of Paracellular Drug Transport in Intestinal Epithelial Cell Monolayers

    Author : Staffan Tavelin; Per Artursson; Staffan Tavelin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; intestinal epithelium; tight junctions; cell culture; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Studies of intestinal drug permeability have traditionally been performed in the colon-derived Caco-2 cell model. However, the permeability of these cell monolayers resembles that of the colon rather than that of the small intestine, which is the major site of drug absorption following oral administration.

  2. 2. Proteomics-informed analysis of drug disposition in the human liver and small intestine

    Author : Christine Wegler; Per Artursson; Pär Matsson; Tommy B Andersson; Manthena Varma; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; protein concentration; drug disposition; drug transport; drug metabolism; human small intestine; human liver; human hepatocytes; human liver microsomes; inter-individual variability; drug clearance; obesity; prediction model; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Orally administered drugs are absorbed in the intestine and generally metabolized in the liver. Therefore, understanding factors determining drug distribution and elimination in these tissues is important. READ MORE

  3. 3. The Hepatobiliary Transport of Rosuvastatin In Vivo

    Author : Ebba Bergman; Hans Lennernäs; Ulf Bondesson; Jack Cook; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rosuvastatin; Biliary excretion; Transport inhibition; Pharmacokinetics; Drug-drug interactions; Hepatobiliary transport; Organic anion transporting polypeptide; OATP; Statins; Gemfibrozil; Cyclosporine; Imatinib; Rifampicin; Canalicular transport; Sinusoidal transport; Hepatic uptake; Hepatic extraction; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

    Abstract : In vivo studies of hepatobiliary disposition are challenging. The hepatobiliary system is complex, as its physiological localization, complex cellular structure with numerous transporters and enzymes, and the interindividual variability in protein expression and biliary flow will all affect the in vivo disposition of a drug under investigation.

  4. 4. Interindividual Variability of Drug Transport Proteins : Focus on Intestinal Pgp (ABCB1) and BCRP (ABCG2)

    Author : Gunilla Englund; Per Artursson; Håkan Melhus; Andreas Kindmark; Joseph W Polli; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; membrane transport proteins; ATP-Binding Cassette Transporters; P-glycoprotein; Breast Cancer Resistance Protein; Interindividual variability; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : The appearance of adverse drug reactions is a common reason for hospitalization in Western countries. Research on underlying biological mechanisms for interindividual variability in drug response aims to better identify patients with exceptional genetic traits, disease conditions or risk of drug-drug interactions and thereby help to prevent adverse drug reactions.

  5. 5. Into the Membrane and Beyond : Improving Membrane Protein Over-Expression in Escherichia coli

    Author : Mirjam Klepsch; Jan-Willem de Gier; Reinhard Grisshammer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; membrane protein over-expression; proteomics; T7 RNA polymerase; peptide transport; strain engineering; Biochemistry; Biokemi; Biophysical chemistry; Biofysikalisk kemi; biokemi; Biochemistry;

    Abstract : Membrane proteins fulfil a wide variety of essential functions in the cell and many are (potential) drug targets. Since their natural abundance is usually very low, most membrane proteins have to be over-expressed for functional and structural studies. READ MORE
