摘要:
Vectors which establish controlled expression of recombinant GHRH genes within tissues at certain levels. The vector includes a 5′ flanking region which includes necessary sequences for expression of a nucleic acid cassette, a 3′ flanking region including a 3′UTR and/or 3′NCR, and a linker which connects the 5′ flanking region to a nucleic acid sequence. The linker has a position for inserting a nucleic acid cassette. The linker does not contain the coding sequence of a gene that the linker is naturally associated with. The 3′ flanking region is 3′ to the position for inserting the nucleic acid cassette.

The present invention pertains to compositions and methods for plasmid-mediated supplementation. The compositions and methods are useful for treating anemia and other effects that are commonly associated in cancer bearing animals. Overall, the embodiments of the invention can be accomplished by delivering an effective amount of a nucleic acid expression construct that encodes a GHRH or functional biological equivalent thereof into a tissue of an animal and allowing expression of the encoded gene in the animal. For example, when such a nucleic acid sequence is delivered into the specific cells of the animal tissue specific constitutive expression is achieved.

The present invention pertains to a method for decreasing the body fat proportion, increasing lean body mass (“LBM”), increasing bone density, or improving the rate of bone healing, or all, of a subject. Overall, the embodiments of the invention can be accomplished by delivering a heterologous nucleic acid sequence encoding GHRH or functional biological equivalent thereof into the cells of the subject and allowing expression of the encoded gene to occur while the modified cells are within the subject. For instance, when such a nucleic acid sequence is delivered into the specific cells of the subject tissue specific constitutive expression is achieved. Furthermore, external regulation of the GHRH or functional biological equivalent thereof gene can be accomplished by utilizing inducible promoters that are regulated by molecular switch molecules, which are given to the subject. The preferred method to deliver the constitutive or inducible nucleic acid encoding sequences of GHRH or the functional biological equivalents thereof is directly into the cells of the subject by the process of in vivo electroporation. A decrease the body fat proportion and an increase in lean body mass (“LBM”), or both of a subject is achieved by the delivery of GHRH or functional biological equivalent thereof as described herein by into the subject as recombinant proteins. In addition, an increase in bone density and improvement in the rate of bone healing is also achieved.

摘要:
One aspect of the current invention is a method of decreasing an involuntary cull rate in farm animals, wherein the involuntary cull results from infection, disease, morbidity, or mortality. Additionally, milk production, animal welfare, and body condition scores are improved by utilizing methodology that administers the isolated nucleic acid expression construct encoding a GHRH or functional biological equivalent to an animal through a parenteral route of administration. Following a single dose of nucleic acid expression vector, animals are healthier and effects are demonstrated long term without additional administration(s) of the expression construct.
