摘要:
Provided herein are biologically active single chain relaxin peptides. In particular the present invention relates to single chain relaxin peptides comprising a B chain derived from relaxin-2, the peptide being truncated by one or more amino acid residues at the N-terminus with respect to the sequence of the B chain of native relaxin-2. Typically the single chain relaxin peptides selectively bind to the RXFP1 receptor.

摘要:
The present invention relates generally to the control of body weight of animals including mammals and humans, and more particularly to nucleic acids encoding materials identified herein as modulators of weight. In its broadest aspect, the present invention relates to the elucidation and discovery of nucleotide sequences, and proteins putatively expressed by such nucleotides, that demonstrate the ability to participate in the control of mammalian body weight. The nucleotide sequences in object represent the genes corresponding to the murine and human ob gene, that have been postulated to play a critical role in the regulation of body weight and adiposity. Preliminary data, presented herein, suggests that the polypeptide product of the gene in question functions as a hormone. The present invention further provides nucleic acid molecules for use as molecular probes, or as primers for polymerase chain reaction (PCR) amplification, i.e., synthetic or natural oligonucleotides.

The invention further relates to methods of diagnosing and treating hypophosphatemic and hyperphosphatemic disorders comprising inhibiting or stimulating, respectively, the biological activity of FGF23 in a patient. The invention also relates to methods of treating osteoporosis, dermatomyositis, and coronary artery disease comprising stimulating the biological activity of FGF23 in a patient.
摘要:
Chicken II and salmon GnRH analog decapeptides resistant to degradation by peptidase incorporating D-arginine, D-leucine, D-tBu-Serine, D-Trp or other active D amino acids at position 6 and ethylamide, aza-Gly-amide or other Gly amide at position 10. The analogs demonstrate preferential binding to male and female reproductive system GnRH receptors. Biopotency is greater within the reproductive system than at the pituitary. These non-mammalian GnRH analogs may be used in pharmaceutical preparations, and specifically in various treatment methods as a contraceptive or post-coital contraceptive agent. The non-mammalian GnRH analogs are also provided in pharmaceutical preparations that may be used clinically for maintaining pregnancy when used in very low doses and administered in pulsatile fashion, as well as in preparations for the treatment of male and female reproductive system disorders. The aza-Gly (10) amide non-mammalian analogs are yet other embodiments of the non-mammalian GnRH analogs provided as a part of the invention.
