  2. 1. Regulation of Vitamin D 25-hydroxylases : Effects of Vitamin D Metabolites and Pharmaceutical Compounds on the Bioactivation of Vitamin D

    Author : Maria Ellfolk; Kjell Wikvall; Maria Norlin; Olavi Pelkonen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP2D25; vitamin D 25-hydroxylase; transcriptional regulation; vitamin D; CYP2R1; CYP2J2; CYP27A1; phenobarbital; efavirenz; fibroblast; LNCaP; Pharmaceutical biochemistry; Farmaceutisk biokemi;

    Abstract : A 700bp portion of the promoter of CYP2D25, the porcine microsomal vitamin D 25-hydroxylase was isolated and sequenced. The computer analysis of the sequence revealed the existence of a putative VDRE at 220 bp upstream of the transcription start site. READ MORE

    Abstract : The nasal passages are constantly exposed to both air- and bloodborne foreign compounds. In particular, the olfactory mucosa is demonstrated to be susceptible to a variety of drugs and chemicals. READ MORE

  5. 3. Expression of Genes Encoding for Drug Metabolism in the Small Intestine

    Author : Monica Lindell; Hans Lennernäs; Matti Lang; Olavi Pelkonen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; CYPs; UGTs; interindividual variation; small intestine; human; rat; artemisinin; CAR-receptor regulation; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi;

    Abstract : This investigation focused on the mRNA expression of drug metabolising Cytochromes P-450 (CYP) and UDP-glucuronosyltransferases (UGT) and the transport protein P-glycoprotein (Pgp) in the small intestine of humans and rats.The mRNA expression of the investigated genes in the human small intestine (duodenum) varies between individuals giving each one of us personal profile.
