since ctx-ldl , added to incubates of normal cells and normal ldl added to ctx fibroblasts suppressed hmg-coa reductase activity and stimulated cholesterol esterification equally , and since 125-i-labeled control ldl was degraded with normal kinetics from the surface of ctx fibroblasts , both ctx-ldl and ctx fibroblasts ldl membrane receptors appear to be biologically normal .
