Abstract: The complete coding sequences and amino acid sequences for both canine and human 32K alveolar surfactant proteins (ASP) are disclosed; clones for the 10K protein have also been obtained. Methods and vectors for obtaining these proteins in recombinant form are described. The availability of large amounts of these proteins through recombinant techniques permits the use of ASP in suitable pharmaceutical compositions in the treatment of respiratory deficiency syndromes.

Abstract: Described are methods and means for the construction and microbial expression of quasi-synthetic genes arising from the combination of organic synthesis and enzymatic reverse transcription from messenger RNA sequences incomplete from the standpoint of the desired protein product. Preferred products of expression lack bio-inactivating leader sequences common in eukaryotic expression products but problematic with regard to microbial cleavage to yield bioactive material. Illustrative is a preferred embodiment in which a gene coding for human growth hormone (useful in, e.g., treatment of hypopituitary dwarfism) is constructed and expressed.

Abstract: Interferon .gamma. is produced in highly purified form (activity exceeding 10.sup.8 units/ml-day) by CHO cells cotransformed by a first plasmid bearing the genomic human interferon gene under the control of the SV40 early promoter, and a second plasmid bearing a DHFR gene under similar control. Methotrexate selection yielded a clone which was a particularly efficient producer. Production of interferon .gamma. may also be facilitated by a Harvey sarcoma virus enhancer sequence.

Abstract: Hybrid useful proteins are prepared by a novel biological system comprising a prokaryotic host transformed with novel hybrid plasmids' .beta.-glucuronidase (BG) gene DNZ and the desired protein gene DNA. Specifically exemplified are plasmids which comprise BG gene DNA and protein A DNA. E. coli K-12 derivative hosts transformed with plasmid pBG3-2.DELTA.n express >60% of the desired fusion protein having protein A-like biological activity. Other useful proteins can be expressed via the elegant highly efficient expression system of the subject invention.

Abstract: The complete nucleotide sequence of the pertussis toxin gene and the deduced amino acid sequences of the individual subunits have been determined. All five subunits are coded by closely linked cistrons and possibly expressed through a polycistronic mRNA, since a promotor-like structure was found in the 5' flanking region. The order of the cistrons is S1, S2, S3, S4, S5, and S3. All subunits contain signal peptides of variable length. The calculated molecular weights of the mature subunits are 25,024 for S1, 21,924 for S2, 21,873 for S3, 12,058 for S4 and 11,013 for S5. All subunits contain signal peptides of variable length. Subunits S2 and S3 share 70% amino acid homology and 75% nucleotide homology. Subunit S1 contains two regions of eight amino acids homologous to analogous regions in the A subunit of both cholera and E. coli heat labile toxins. Functional domains in relation to the primary structure and the development of a safer, new generation vaccine against whooping cough are presented.

Abstract: Genetic transformation of a zygote and the embryo and mature organism which result therefrom is obtained by placing or inserting exogenous genetic material into the nucleus of the zygote or into any genetic material which ultimately forms at least a part of the nucleus of the zygote. It is preferred that the exogenous genetic material be added to a pronuclei of the zygote and is particularly preferred that it be added to the male pronucleus of the zygote. Thereafter, the zygote is allowed to undergo differentiation and development into the organism. The genotype of the zygote and the organism which results therefrom will include the genotype of the exogenous genetic material and the exogenous genetic material will be phenotypically expressed.The invention can be utilized in a variety of ways including, for example, animal and plant breeding to modify or create new species, it can be used in epigenetics and in the understanding and treatment of genetic diseases.

Abstract: Mammalian genes that encode hormones are cloned and linked to strong promoter DNA sequences. The linked sequences are inserted in plasmids for amplification in prokaryotic cells, and multiple copies of the linked sequences are excised therefrom. Linked sequences are subsequently microinjected into fertilized eggs and the fertilized eggs are implanted into pseudo-pregnent females of the same species. As a result, transgenic animals are born having the linked sequences incorporated into their genomes and expressing the gene-encoded hormone. Because multiple copies of the linked sequences are frequently inserted and because production of the hormone is not limited to certain organs, as is the case with most endogenous hormones, the transgenic animals produce substantial amounts of the hormone. Hormone can be harvested from the living animal (and from its hormone-producing progeny) by extracting fluid, such as blood serum or ascites fluid, on a regular basis.
