The effects of major storage globulins from soybean on cholesterol homeostasis were investigated in vitro and in vivo systems. The low density lipoprotein (LDL) uptake and degradation was studied both in human skin fibroblasts (HSF) and in a human hepatoma cell line (Hep G2). In Hep G2 cells a dose-dependent increase of both uptake and degradation of 125I-LDL was induced by the 7S globulin, whereas the 11S globulin exerted a lesser effect that was not dose-related. In HSF cells the 11S globulin increased the uptake of 125I-LDL to a greater extent than did 7S globulin; in this cell line, LDL degradation was not stimulated by either of the globulins. Rats fed a casein-cholesterol diet were treated daily with the 11S or 7S globulins for 2 wk. The administration of soybean globulins significantly reduced cholesterolemia (-35 and -34% with 7S and 11S globulins, respectively, vs. controls). Liver membrane preparations from the casein-cholesterol-fed rats showed a nonsignificant increase in the maximal binding of labeled cholesterol-rich lipoprotein fraction (beta-VLDL) to high affinity receptors.
