      Isolation of inhibin like peptides from human placenta

      More Details Abstract Fulltext PDF

      Two moieties of inhibin could be obtained by chromatography of partially purified preparations of inhibin from human placenta on Sephadex G-100, G-25 and ion exchange chromatography on diethylaminoethyl Sephadex A-50. The higher molecular weight moiety (14,000) designated as HPI-H appears to be similar to inhibin from human seminal plasma. While the lower molecular weight moiety (1500) designated as HPI-L appears to be similar to that of sheep testicular inhibin.

      The preparations from both human term placenta and human seminal plasma inhibited the binding of [125I] human follicle stimulating hormone to rat testicular receptors. This effect of inhibins could be neutralized by antisera raised against corresponding polypeptide. Further these antibodies could neutralize endogenous inhibin resulting in 2 to 3 fold increase in serum follicle stimulating harmone levels, which could then be reversed by exogenous administration of the isolated inhibin preparations.

      Forthcoming Special issue.


    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".


      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.


      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.


      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
