Molecular Heterogeneity of Luteinizing Hormone-Releasing Hormone

Part of the Biochemical Endocrinology book series (BIOEND)


Following the structural elucidation of luteinizing hormone-releasing hormone (LH-RH) by Schally and associates, it became generally accepted that the decapeptide was a unique molecular form. This belief arose from:
  1. (a)

    A number of studies purporting to have shown non-ribosomal biosynthesis of LH-RH and thereby excluding the possibility of ribosomally biosynthesised prohormonal forms.

  2. (b)

    The assumption that LH-RH was confined to the CNS and thus unlikely to be present in other tissues in a modified form.

  3. (c)

    Immunological and low resolution chromatographic studies demonstrating that LH-RH in the hypothalamus of nonmammalian vertebrates was identical to the mammalian peptide. This conclusion of a lack of interspecific differences in LH-RH structure in vertebrates was supported by the demonstration that synthetic mammalian LH-RH was biologically active in a wide range of mammalian species and in nonmammalian vertebrates (1).
