Abstract

The hypophysiotropic peptide, growth hormone-releasing factor (GRF), was isolated from human hypothalamic-hypophysial tissues by means of acid extraction, immunoaffinity chromatography, gel filtration, and two steps of reverse-phase high-performance liquid chromatography. Amino acid sequence determination using a gas-phase sequencer and reverse-phase liquid chromatography of the native peptide and its synthetic replicates showed its primary structure to be as follows: H-Tyr-Ala-Asp-Ala-Ile-Phe-Thr-Asn-Ser-Tyr-Arg-Lys-Val-Leu-Gly-Gln -Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Met-Ser-Arg-Gln-Gln-Gly-Glu-Ser -Asn-Gln-Glu-Arg-Gly-Ala-Arg-Ala-Arg-Leu-NH2, which is identical to that of the GRF recently isolated and characterized from a human pancreatic tumor that had caused acromegaly. Human hypothalamic GRF shows major homologies (93%, 89%, and 86%, respectively) when its primary structure is compared to that of the hypothalamic GRF from the porcine, bovine, caprine, and ovine species.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
