The invention discloses a multi-gene pyramiding breeding method for thoroughbred milk goats. Genome DNA (deoxyribonucleic acid) of a milk goat continuously giving birth to two or more lambs is used as a template, four pairs of primers respectively expand intron 2 and exon 10 of a prolactin receptor gene and an untranslation region (5'UTR) and exon 1 of luteotropin beta calcmeurin 5', the sizes of expanded products are judged by agarose gel electrophoresis, site mutation of the expanded products of the four pairs of primers are screened by DNA sequencing technology, then polyacrylamide gel electrophoresis is used for performing genetic typing and gene frequency analysis for SNPs (single nucleotide polymorphisms) of four sites of the prolactin receptor gene and the luteotropin beta calcmeurin, the relation of polymorphism of a multiple-birth milk goat individual (F1 generation) and the number of born lamps and the relation of different genetype combinations and the number of the born lamps are analyzed, parental generation (F0 generation) is reviewed, filial generation (F2 generation) is tracked, the relation of the genetype combination of an ewe individual and the number of the born lamps is detected, and contribution of different genetypes in terms of prolific trait formation is analyzed.

The subject invention provides materials and methods for producing animals with short hair length. In a preferred embodiment, this is accomplished by altering in the animal the nucleotide sequence that encodes the prolactin receptor (PRLR) protein such that a truncated version of the protein is produced. Advantageously, and surprisingly, the truncated protein produced according to the subject invention retains lactogenic functionality, but causes the animal to have a short-hair coat.

The invention discloses a breeding method of multi-gene pyramiding of fine breed milk goats, which comprises the following steps: using genome DNA of milk goats continuously bearing two or more than two goats as a template; using four pairs of primers for respectively amplifying intrones 2 and exons 10 of prolactin receptor genes, and the 5' non-translational region (5' UTR) and exons 1 of luteotropin beta subunit genes; using agarose gel electrophoresis for carrying out size determination on each amplifying product; adopting the DNA sequencing technology for sieving and checking the site-directed mutation of the amplifying products of the four pairs of the primers; then, using polyacrylamide gel electrophoresis for carrying out gene typing and gene frequency analysis on the SNPs of the four sites of the prolactin receptor genes and the luteotropin beta subunit genes; analyzing the relationship between the goat bearing number and the polymorphism of the high-yield milk goat individuals (generation F1) and the relationship between different gene type combinations and the goat bearing number; tracing to the parent generation (generation F0); tracking filial generation (generation F2); detecting the relationship between the goat bearing number and the gene type combinations of the female goat individuals; and analyzing the contribution of different gene types in the prolific trait formation.

The present invention is directed to neutralizing prolactin receptor antibodies 002-H06 and antigen binding fragments, pharmaceutical compositions containing them and their use in the treatment or prevention of benign disorders and indications mediated by the prolactin receptor such as endometriosis, adenomyosis, non-hormonal female contraception, benign breast disease and mastalgia, lactation inhibition, benign prostate hyperplasia, fibroids, hyper- and normoprolactinemic hair loss, and cotreatment in combined hormone therapy to inhibit mammary epithelial cell proliferation. The antibodies of the invention block prolactin receptor-mediated signaling.

The invention relates to variants of prolactin, which variants have high affinity for the prolactin receptor.

Compositions and methods for delivering an agent to a cell comprising a prolactin receptor are provided. Also provided is a method of inhibiting a breast, ovarian or prostate cancer cell, where the method includes a step of contacting the cell with a complex comprising a prolactin receptor ligand linked to at least one of an RNAi-inducing agent, a polynucleotide sequence encoding a polypeptide, an miRNA, a cytotoxic moiety, a chemotherapeutic moiety, a radioactive moiety or a nanoparticle. Methods of detecting a cancer cell expressing a prolactin receptor are also provided.

The present invention provides compositions and methods for making multimeric proteins to increase stability over their monomer. For example, more stable growth hormone and prolactin receptor agonists are provided.

The invention relates to the raise livestock field, and discloses a method for predicating milk yield of small tailed han sheep by virtue of BMPR(bone morphogenetic protein receptor )-1B or PRLR (prolactin receptor) gene SNP (single nucleotide polymorphism) lotus. The method comprises the following steps: extracting a small tailed han sheep genome DNA (deoxyribonucleic acid); amplifying a sequence of SNP lotus-containing BMPR-IB A746G or a sequence of SNP lotus-containing PRLR gene; judging an E2-C34T mutant gene type of the BMPR-IB A746G or PRLR gene. The method disclosed by the invention can be applied to carrying out feeding and management according to difference of milk secretion control gene types, and can be used for improving the milk secretion amount, guaranteeing that a lamb has enough milk intake, improving the survival rate and reducing the breeding economic loss. The method disclosed by the invention provides a molecular-level technical support for predicating and molecularly selecting the milk yield of small tailed han sheep; by applying the method disclosed by the invention, the survival rate and development rate of the lambs are greatly improved, so that better breeding economic benefits are produced, and therefore, the method has good application prospect.

The present invention concerns methods and tools for determining a specific treatment of a prolactin associated disorder. The treatment is selected based on the expression pattern of growth hormonereceptor (GHR), prolactin receptor (PrlR) and the suppressors SOCS2 and TCS2.

The invention discloses a method for judging lateolabrax japonicus aquatic water. The method specifically comprises the following steps: extracting total RNA (Ribonucleic Acid) from lateolabrax japonicus tissues to be judged, and synthesizing a first cDNA (complementary Deoxyribonucleic Acid) chain; amplifying a prolactin receptor via a PCR (Polymerase Chain Reaction); observing whether a prolactin receptor expression strap exists on the gel electrophoresis picture of a PCR amplification product or not in order to judge whether lateolabrax japonicus under detection is cultured in fresh water or sea water. The method disclosed by the invention is simple and accurate, and can be applied to supervision in the field of aquatic products.
