TL;DR

The similarities between the two hormones are discussed, including crossreactivity with strictly specific anti-hGH monoclonal antibodies, which underlie the hypothesis that S. mansonoides has obtained and expresses a human gene for GH.

Abstract

Plerocercoids of the tapeworm, Spirometra mansonoides, produce a factor with characteristics similar to those of mammalian growth hormone (GH). Plerocercoid growth factor (PGF) stimulates growth and mimics other actions of GH but does not possess the anti-insulin/diabetogenic activities intrinsic to mammalian growth hormones. Duplication of activities unique to human GH, chemical and physical similarities, plus crossreactivity with strictly specific anti-hGH monoclonal antibodies, underlie the hypothesis that S. mansonoides has obtained and expresses a human gene for GH. In this article, Kirk Phares discusses the similarities between the two hormones.
