    Pharmacogenomika: 80 lamotrigint vagy carbamazepint szedő beteg- súlyos cután gyógyszermellékhatással vagy a nélkül adatait és DNS-ét archiváltuk. A DNS mintákat CYP2D6 és CYP2C19 polymorphismusra Amplichip CYP450 IVD kittel Affymetrix Gene Chip Fluidics Station 450-en és/vagy Affymetrix Drug Metabolizing Enzymes and Transporters (DMET+) rendszerben vizsgáltuk. 4 technikai probléma- prolongált vizsgálat: 1, Az első mérések elavult software-t jeleztek, cseréltük 2. Ez új 7G reading chip rendszert igényelt. A 4 állomásból 3 működik 3, A két Roche teszt-chip lejárt kóddal érkezett 4, Előzetes génvizsgálatokat kezdtük az Affymetrix Genotyping Console software-rel, DMET chipeken, de a releváns eredmények PCR re-tesztelése most zajlik. További vizsgálatok Állati eredetű anabolikus steroidok és fokozott aminosav bevitele volt a kiváltó faktor eosinophil fasciitises testépítő betegünkben,akiben a készítmények alkalmazását követően új, állati eredetű mycoplasma arginini fertőzést igazoltunk. Súlyos gyógyszermellékhatásban szenvedő betegeinket teszteltünk társuló mycoplasma infekciókat PCR-rel és szerológiai módszerekkel. Bevezettük az epicutan gyógyszertesztelést tünetmentes betegeinkben. Atomerőműben szűrtünk bőrdaganatokat- szabadidős UV expozíció hatását igazoltuk- (fényérzékenyítő gyógyszereket nem szedtek). Két magyar összefoglaló tanulmány: 1, Toxicodermákban végzett LTT tesztek eredményéről 2, Erythema multiformében a gyógyszermellékhatásgyakoriságáról. | Pharmacogenomics: data and DNA from 80 patients under lamotrigine or carbamazepine therapy with or without severe cutaneous adverse effects were collected. DNAs were analyzed for CYP2D6 and CYP2C19 polymorphisms by Amplichip CYP450 IVD kit on an Affymetrix Gene Chip Fluidics Station 450 and by Affymetrix Drug Metabolizing Enzymes and Transporters (DMET + Solution) chip. 4 problems - study prolongation. 1, Uncertain data indicated an old software system, the change needed new 7G reading chips in our Affymetrix Station. 2,Still, one out of 4 stations is not working currently 3, Two Roche test chips arrived by expired codes 4, Preliminary genetic studies were also performed by an Affymetrix Genotyping Console software on a DMET chip and relevant genes and polymorphisms are currently under PCR re-testing. Further studies In a patient with eosinophil fasciitis induced by anabolic steroid and aminoacid intake from uncontrolled animal sources we identified a new animal mycoplasma arginini infection. In patients severe drug adverse reactions associated mycoplasma infections were studied by PCR and immunology. We introduced the patch testing for drug sensitivity. In a Hungarian nuclear power plant screened for cutaneous malignancies the role of outdoor UV was identified - without drug induced photosensitivity. Hungarian papers on lymphocyte transformation drug testing and erythema multiforme also related to drug sensitivity were published

    NLS copy number variation governs efficiency of nuclear import: case study on dUTPases

    Nucleocytoplasmic trafficking of large macromolecules requires an active transport machinery. In many cases, this is initiated by binding of the nuclear localization signal (NLS) peptide of cargo proteins to importin-a molecules. Fine orchestration of nucleocytoplasmic trafficking is of particularly high importance for proteins involved in maintenance of genome integrity, such as dUTPases, which are responsible for prevention of uracil incorporation into the genome. In most eukaryotes, dUTPases have two homotrimeric isoforms: one of these contains three NLSs and is present in the cell nucleus, while the other is located in the cytoplasm or the mitochondria. Here we focus on the unusual occurrence of a pseudo-heterotrimeric dUTPase in Drosophila virilis that contains one NLS, and investigate its localization pattern compared to the homotrimeric dUTPase isoforms of Drosophila melanogaster. Although the interaction of individual NLSs with importin-a has been well characterized, the question of how multiple NLSs of oligomeric cargo proteins affect their trafficking has been less frequently addressed in adequate detail. Using the D. virilis dUTPase as a fully relevant physiologically occurring model protein, we show that NLS copy number influences the efficiency of nuclear import in both insect and mammalian cell lines, as well as in D. melanogaster and D. virilis tissues. Biophysical data indicate that NLS copy number determines the stoichiometry of complexation between importin-a and dUTPases. The main conclusion of our study is that, in D. virilis, a single dUTPase isoform efficiently reproduces the cellular dUTPase distribution pattern that requires two isoforms in D. melanogaster
