2. 11. Regulation of tissue factor expression in myeloid and monocytic leukaemia cells

   Author : Taavo Tenno; Uppsala universitet; []
   Keywords : Medical sciences; tissue factor; blood coagulation; monocytes; cell differentiation; retinoic acid; vitamin D3; acute promyelocytic leukaemia; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

   Abstract : Tissue factor (TF) is a transmembrane glycoprotein that initiates the blood coagulation cascade and is also involved in cell migration, tumour metastasis and angiogenesis. Pathologic expression of tissue factor by monocytes contributes to several thrombotic complications like acute coronary artery disease and disseminated intravascular coagulation. READ MORE

4. 12. Regulation of morphogen signalling during neural patterning in the Xenopus embryo

   Author : Hooi Min Tan Grahn; Avdelningen för molekylärmedicin och genterapi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Suppressor-of-fused; Gli; β-Catenin; Neural; Xenopus; FGF; Signalling; HtrA1; RDH10; Retinol dehydrogenase; Retinoic acid; Spemann s organizer; Induction; Gradient;

   Abstract : Morphogens such as Hedghog, Wnt, FGF, and retinoic acid are important signals whose concentrations need to be tightly regulated in the vertebrate embryo to ensure body axis development and formation of the central nervous system. We first show that the intracellular cytoplasmic protein XSufu acts as a dual regulator of Hedgehog (Hh) and Wnt signals during neural induction and patterning in the Xenopus embryo. READ MORE

5. 13. Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression

   Author : Katharina Bruzelius; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; milk; Natural science; cancer; prolactin; insulin; hydrocortisone; retinoic acid; MAC-T; northern blot; two-dimensional electrophoresis; bovine mammary gland; selenium; selenoprotein;

   Abstract : Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. READ MORE

6. 14. Studies on Human Endogenous Retroviruses (HERVs) with Special Focus on ERV3

   Author : Ann-Catrin Andersson; Bengt Widegren; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; human endogenous retroviruses; HERV; ERV3; expression; in situ hybridisation; real-time PCR; U-937; retinoic acid.; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   Abstract : Human endogenous retroviruses (HERVs) represent approximately 7% of the human genome. This investigation was focused on one particular HERV, ERV3, with the main purpose of characterising its gene expression patterns and genomic distribution of ERV3-like sequences. READ MORE

7. 15. Proteolytic processing of the Alzheimer APP protein family during neuronal differentiation

   Author : Sofia Holback; Kerstin Iverfeldt; Nigel Hooper; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APP; APLP1; APLP2; differentiation; processing; retinoic acid; secretase; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

   Abstract : Increased amyloid-β (Aβ) load in the brain, neurite degeneration, neuronal loss, and decreased levels of several neurotrophins are among the characteristics of Alzheimer’s disease (AD). Generation of Aβ occurs when the amyloid precursor protein (APP) is proteolytically processed by β- and γ-secretases in the amyloidogenic pathway. READ MORE
