Description

DK 173259 B1 i
Den foreliggende opfindelse angår humant papillomavirus type 41-DNA, et diagnostikum indeholdende DNA'et, anvendelsen af DNA'et samt en fremgangsmåde til diagnosticering af HPV 41-infektioner.
t 5 Humane papillomaviruser (HPV) danner en gruppe på ca. 40 forskellige typer (H. zur Hausen og A. Schneider, (1987), The Papillomaviruses, P.M. Howley og N.P. Salzmann, ed.). HPV er fundet i sammenhæng med godartede (vorter, kon-dylomer i genitalområdet) og ondartede (carcinomer i hud og 10 skede) epitheliale neoplasmer. Papillomaviruser kan ikke formeres i kultur. Anvendelsen af humant papillomavirus type 41-DNA (HPV 41-DNA) som diagnostikum samt udvinding af ekspressionsprodukter forudsætter således genteknologiske fremgangsmåder.
15 Det har været formålet med opfindelsen at tilveje bringe sådanne genteknologiske fremgangsmåder.
Til grund for opfindelsen ligger isolering for første gang af HPV 41, en delvis karakterisering af dets genom samt kloning i pUC 19. Herved åbnes mulighed for tidlig 20 diagnose af hudtumorer, der er knyttet til HPV 41.
Opfindelsen angår således HPV41-DNA, som er ejendommeligt ved, at det er en klon med deponeringsnummeret DSM 4175 P eller DSM 4174 P.
Opfindelsen angår også et diagnostikum, som er ejen-25 dommeligt ved, at det indeholder DNA ifølge opfindelsen eller dele deraf.
Opfindelsen angår desuden anvendelsen af DNA ifølge opfindelsen til genteknologisk ekspression af proteiner.
Opfindelsen angår endvidere en fremgangsmåde til 30 diagnosticering af HPV 41-infektioner, hvilken fremgangsmåde er ejendommelig ved, at biopsimateriale eller afskrabet materiale bringes i kontakt med et diagnostikum ifølge opfindelsen, eller at RNA eller DNA, som skal undersøges, hybridiseres med DNA ifølge opfindelsen.
35 Yderligere udførelsesformer for opfindelsen er be skrevet nærmere i det følgende.
2 DK 173259 B1
Kloningen af HPV 41 har muliggjort sammenligning med 40 andre HPV. HPV 7, 8, 10, 17, 27, 29, 30 og 33 er fjernt beslægtede, idet der er påvist kolinearitet af HPV 41 med HPV 8 (fig. 2) og er tilvejebragt fysiske genomkort for 5 restriktionsenzymspaltninger (fig. 1).
Der er dermed åbnet mulighed for at undersøge neopla-sier, især carcinomer i huden, for forekomst af HPV 41.
Eksempler 10 1. Isolering af episomalt HPV 41-DNA.
Biopsier fra vortevæv fra tre forskellige hudarealer hos en 15-årig pige dybfryses umiddelbart efter tilvejebringelsen ved -70eC og opbevares. Deraf isoleres højmolekylært DNA som beskrevet af Gissmann et al. (1982), Int. J. Cancer 15 29, 143-146. Ringformigt lukket dobbeltstrenget DNA udvindes fra det nævnte cellulære DNA ifølge Radioff et al. (1967)
Proc. Nat. Acad. Sci. 57, 1514-1521, idet ca. 10 /*g DNA
centrifugeres i en 50 Ti-rotor (Beckmann Corp.) ved 45.000 o/m i 48 timer i cæsiumchlorid (vægtfylde 1,56 g/ml) med til-20 sætning af 60 0 /ig/ml ethidiumbromid, hvorefter der opsamles fraktioner med en vægtfylde på 1,59-1,60. Alternativt kan episomalt HPV 41-DNA af ikke-spaltet DNA fra det samme biop-simateriale påvises i agarosegeler farvet med ethidiumbromid (1% agarose (Seakem ME) i 40 mM Tris-acetat, 2 mM EDTA (pH-25 værdi 7,8)) og isoleres derfra.
2. Kloning af HPV 41 i plasmid pUC 19.
Som kloningsvektor vælges det kendte plasmid pUC 19 (Yanish-Perron et al. (1985), Gene 33.» 113-119). Cirkulært 30 lukket dobbeltstrenget DNA klones i pUC 19 efter spaltning med BamHI (Maniatis et al. (1982), Molecular Cloning: A
Laboratory Manual; Cold Spring Harbor Laboratory Press, New York) . Rekombinante kloner identificeres ved en β-galacto-sidase-test (Messing et al. (1977), Proc. Nat. Acad. Sci.
3 5 USA 74., 364 2-3646) , og indligerede DNA-stykker analyseres efter DNA-hurtigekstraktion (H.L. Birnboim og Doly. (1979) , 3 DK 173259 B1
Nuel. Acids Res. 7, 1513-1523).
Der fås to rekombinanter, hvoraf den ene, K 10, indeholder en indsats på 6,6 kb, og den anden, K 6, indeholder en indsats på 0,98 kb. Homologien af disse klonede sekvenser , 5 er påvist ved hybridisering med episomalt DNA fra biopsimate- riale.
3. Fysiske genomkort af HPV 41.
HVP 41-DNA fraskilt fra vektoren ved BamHI-spaltning 10 nedbrydes med restriktionsendonukleaserne Accl, Bglll, Xbal,
Smal, EcoRI, PstI og Hindi, og de tilsvarende fysiske genomkort tilvejebringes ved almindeligt kendte metoder. Resultaterne er sammenfattet i fig. l, hvor det singulære Kpnl--spaltningssted tjener til at linearisere HPV 41-molekylet.
15 4. Sammenligning med andre HPV.
DNA af HPV 41-genomet sammenlignes med DNA’er af 40 tilgængelige HPV-typer ved hjælp af DNA/DNA-hybridisering under forskellige stringens (E.M. Southern (1975), J. Mol.
20 Biol. j?8, 503-517). Under betingelser med høj stringens (smeltetemperatur Tm = -20°C) hybridiseres HPV 41-K 10-DNA delvis med HPV 29-DNA. DNA af K 6-klonen hybridiserer kun ved lav stringens (Tm = -40°C) med HPV 3- og 13-DNA.
Kolineariteten med HPV 8 på grundlag af hybridise-25 ringsforsøg er vist i fig. 2.
Med kendskab til HPV 8-DNA-sekvensen (Fuchs et al.
(1986), J. Virol. 58, 626-634) kan den åbne læseramme af HPV 41 afledes, og dermed bliver det muligt at få HPV 41--proteinerne ved almindeligt kendte metoder til subkloning 30 af klonerne K 10 og K 6 med efterfølgende ekspression i prokaryotiske eller eukaryotiske ekspressionssystemer.
Plasmiderne HPV 41, klon K 6 og K 10 er deponeret (i E. coli) den 3. juli 1987 hos Deutsche Sammlung fur Mikroorganismen under numrene DSM 4174P (K 6) og DSM 4175P (K 10) .
