    摘要: Chimeric oligonucleotide of the formula 5′-W—X1—Y—X2—Z-3′, where W represents a 5′-O-alkyl nucleotide, each of X1 and X2 represents a block of seven to twelve phosphodiester-linked 2′-O-alkyl ribonucleotides, Y represents a block of five to twelve phosphorothioate-linked deoxyribonucleotides, and Z represents a blocking group effective to block nuclease activity at the 3′ end of the oligonucleotide, are described. These compounds exhibit high resistance to endo- and exonucleases, high sequence specificity, and the ability to activate RNAse H, as evidenced by efficient and long-lasting suppression of target mRNA. The oligonucleotides are preferably transfected into cells in formulations containing a lipid-peptoid conjugate carrier molecule of the formula L-linker-[N(CH2CH2NH2)CH2(C═O)—N(CH2CH2R)CH2(C═O)—N(CH2CH2R)CH2(C═O)]3—NH2, where L is a lipid moiety, including a steroid, and each group R is independently selected from alkyl, aminoalkyl, and aralkyl.

    摘要: A gene having a DNA sequence complementary to that of the glucoamylase polypeptide mRNA from a fungal species, preferably Aspergillus awamori, is prepared. The mRNA is an approximately 2.2 kilobase poly A RNA obtained from fungal cells grown under conditions of glucoamylase induction. Reverse transcription of the mRNA provides a glucoamylase probe used to identify genomic digest fragments containing glucoamylase gene regions, which are sequenced to locate the introns and exons. The genomic fragments are spliced together to form a gene having a DNA sequence with altered or deleted introns which codes for fungal glucoamylase protein and is capable, when correctly combined with a cleaved DNA expression vector, of expressing a non-native protein having glucoamylase enzyme activity upon transformation of a host organism by the vector. The host is preferably bacteria or yeast. The transformed yeast host may be used to produce ethanol.

    摘要: DNA constructs are prepared which operably link human interferon genes, selective, eukaryotic marker genes, and promoter and expression control sequences for the expression of human interferon in Chinese hamster ovary (CHO) cells or progeny thereof. The human recombinant interferon so produced contains glycans which are a subset of the population of glycans which are contained in the native counterpart, and may be used in therapeutic formulations. The CHO cells yield high levels of human interferon with no detectable amounts of host IFN, either constitutive or inductive.
