      Interaction of [125I]-insulin with intact hepatocytes and its correlation with circulatory insulin level was examined. The hepatocytes from new-born rats bound lowest amount of [125I]-insulin (1.39±0.41 pM/mg cell protein) when circulatory insulin level was high (8±1.5 ΜU/ml). Hepatocytes from 7 day and 21 day old animals demonstrated a more or less similar relationship, Cells from 31 day old animals exhibited maximum insulin binding, activity (5.13±0.18.pM/mg cell protein) against a low serum insulin level (4.25±0.25 ΜU/ ml). Scatchard analysis of insulin binding shows that the affinity is higher in the hepatocytes from new-born animals than in the hepatocytes of 31 day old animals. Higher binding observed in the latter case may be due to a greater number of binding sites. Hepatocytes from one year old rats bound very little insulin (2.50±0.36 pM/mg cell protein) against a high circulatory insulin level (9.25±0.85 ΜU/ml). In view of these results, it appears that the down-regulation hypothesis holds true during ontogeny too.

      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
