Results from this study3

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In the domestic cat hypothalamus, immunoreactive kisspeptin was localized in the periventricular and infundibular nuclei.

    In plain wordsIn domestic cats, the body's own kisspeptin was found in two regions of the hypothalamus.

    Summary
    Using an anti-Kp10 antibody, we found the immunoreactive kisspeptin to be localized in the periventricular and infundibular nuclei of the cat hypothalamus.

    This result measures the body's own Kisspeptin-10. Nobody was given the peptide. It is not evidence about taking it.

Studies that did not test the peptide alone2

In this study, Kisspeptin-10 was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Kisspeptin-10.

    Feline Kiss1 cDNA has an open reading frame of 450 base pairs that encodes a precursor protein of 149 amino acids.

    In plain wordsIn cats and related felines, the kisspeptin gene codes for a precursor protein of 149 amino acids.

    Summary
    Nucleotide sequencing revealed that domestic cat Kiss1 cDNA is of 711 base pairs and caracal Kiss1 cDNA is of 792 base pairs, both having an open reading frame of 450 base pairs, encoding a precursor protein Kiss1 of 149 amino acids.

    In this study, Kisspeptin-10 was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Kisspeptin-10.

    The core sequence of feline kisspeptin Kp10 was identical in all species analyzed and is highly conserved in other vertebrates.

    In plain wordsThe core Kp10 sequence is the same in all cat-family species tested and is highly conserved in other vertebrates.

    Summary
    The core sequence of the feline kisspeptin Kp10 was found to be identical in all species analyzed here and is highly conserved in other vertebrate species.

    In this study, Kisspeptin-10 was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Kisspeptin-10.
