Altered biochemical responses by rat Sertoli cells and peritubular cells cultured under simulated diabetic conditions

Summary

The purpose of the present study was to determine whether the secretion of androgen-binding protein and lactate by 16-day-old rat Sertoli cells is altered when these cells are cultured in simulated diabetic conditions. Incorporation of 3H-uridine into RNA by peritubular cells cultured in simulated diabetic conditions was also studied. The cells were exposed to various concentrations of glucose, β-hydroxybutyrate, sodium bicarbonate (to alter the pH of the medium), mannitol (to influence the osmolarity of the medium), or a combination of these compounds. All of the metabolic parameters when tested alone or in combination were capable of increasing lactate secretion by Sertoli cells above control values. Basal secretion of androgen-binding protein, however, was not influenced by any individual component or when all components were tested together. FSH-stimulated levels of androgen-binding protein secretion was depressed only when the Sertoli cells were exposed to all the components simultaneously. Incorporation of uridine by peritubular cells was decreased by exposing the cells to butyrate or mannitol, while no effect was observed with glucose treatment. These results indicate that Sertoli cell and peritubular cell function can be directly altered by several specific metabolic parameters associated with diabetes.
