Synthetic 4,5-didehydro geranylgeranoic acid, a potent ligand both for cellular retionoic acid-binding protein and for nuclear retinoid receptors, induced apoptosis in human hepatoma-derived cell line HuH-7 but not in primary hepatocytes, although all-trans or 9-cis retinoic acid did not induce any growth inhibition(Ref. 0081). A synthetic geranylgeranoic acid (GGA) induced apoptotic cell deth in a human hepatoma cell line, HuH-7, but not in mouse primary cultured hepatocytes. Prior to chromatin condensation, GGA induced a dramatic loss of the mitochondrial membrane potential in 1 hour and in a dose dependent manner in HuH-7 cells, but not in the primary hepatocytes. GGA induces apoptosis in hepatoma cells through derangement of mitochondrial function and subsequent activation of the cysteine protease cascade(Ref. 0082).

The effects of dietary proteins on the accumulation of dolichol in kidney, spleen, brain, and heart were studied. There were increases in dolichol contents in rat tissues with age. The contents of kidney and spleen were influenced by the diet(Ref. 0057). Dolichol content in different regions of the rat brain (cerebral cortex, striatum, hippocampus, cerebellum, and brain stem) were analyzed from birth to the age of 2 years. The level of dolichol increased almost 100-fold during the first 10 months of life and continued to increase thereafter(Ref. 0058).

Age-related chnges of dolichyl phosphate content in rat and human tissues (Ref. 0051). Biosynthesis of dolichol from mevalonic acid was measured in non-malignant and malignant cultured human lymphocytes, freshly isolated human mononuclear leucocytes and in cultured human hepatoma cells(Ref. 0069). Formation of dolichol from dehydrodolichol is catalyzed by NADPH-dependent reductase localized in microsomes of rat liver. Dolichol was syntesized from isopentenyl diphosphate and Z,E,E-geranylgeranyl diphosphate. Neither dolichyl diphosphate nor dolichyl phosphate was detected(Ref. 0092). Farnesyl diphosphate is the common intermediate at the branch point for the synthesis of geranylgeranylated proteins as well as cholesterol, ubiquinone, dolichol, and farnesylated proteins(Ref. 0070). Dolichol contents of various organs of mice used as a model for Niemann-Pick's type C disease . Contents in subfractions isolated from the liver of mice used as a model for NPC (mitocondria, lysosomes, microsomes)(Ref. 0071).

The effects of TSH on dolichol-linked sugar pools and oligosaccharyltransferase activity in thyroid cells were investigated. TSH slightly increased the amount of dolichol and acitivated the oligosaccharyltransferase(Ref. 0072). Dehydrodolichol is a common branch point intermediate in the biosynthetic pathways leading to dolichal and dolichol(Ref. 0073). Metabolism of dolichol, dolichoic acid, and nordolichoic acid in MDCK and HepG2 cells were investigated. Dolichoic acid was broken down by alpha-oxidation and also converted to a mixture of polar compounds. No oxidative breakdown of dolichol was found(Ref. 0074). The potential for feedback inhibition by isoprene intermediates in the isoprene biosynthetic pathway was investigated. The relative inhibitory capasity were as follows: GG-PP > F-PP > G-PP > FOH > dol-P. GOH and dolichol were not inhibitors(Ref. 0039). Age-dependent changes in hepatic dolichol content in rats fed either ad libitum, or subjected to restriction of daily food intake or every-other-day feeding ad libitum (antiaging dietary restriction). Both types of antiaging dietary restriction fully prevented the age-associated accumulation of dolichol in the liver and had a much smaller preventive effect in the kidney(Ref. 0075/0076).
The effects of alcohol and glucagon on the biliary excretion of dolichols in rats were investigated. Chronic ethanol treatment decreased both biliary dolichol and beta-hexosaminidase excretion. The absolute amount of dolichol excreted into the bile correlated highly significantly with the absolute amount of biliary beta-hexosaminidase. Biliary dolichols are derived from hepatic lysosomes(Ref. 0077). Modifications in the concentration and distribution of rat liver microsomal dolichol and dolichyl phosphate after acute ethanol adiministration (6 g/kg body weight) were investigated. Between 3 and 24 hr after ethanol administration, the microsomal dolichyl phosphate concentration was significantly lower than in control rats. An earlier and more marked reduction of total dolichol was observed in the Golgi apparatus(Ref. 0059). Pro-oxidant agents lead to a significant decrease of both free dolichol and dolichyl phosphate in isolated rat hepatocytes(Ref. 0059).

The biological role of dolichol (review)(Ref. 0043). Content of dolichol and activity of GlcNAc-1-P (UDP-N-acetylglucosamine:dolichyl phosphate N-acetylglucosamine 1-phosphate transferase) in fibroblasts from patients with carbohydrate-deficient-glycoprotein (CDG) syndrome were analyzed. The major defect of CDG syndrome is not found in the synthesys of dolichyl phosphate or GlcNAc-PP-Dol(Ref. 0061). Extraction of microsomes with n-heptane and subsequent reincorporation of dolichol were done in order to investigate the influence of dolichol on microsomal membrane functions. Dolichol affected microsomal membrane fluidity, but did not modify the activities of certain microsome membrane enzymes(Ref. 0062). Dolichol was covalently bound to cellular proteins with size of 5, 10, 27, 75, and >140 kDa(Ref. 0063). HMG-CoA reductase inhibitors induce apoptosis in mouse proximal tubular cells in primary culture. Geranylgeranylpyrophosphate and mevalonate completely reversed the effect of the inhibitors, while farnesylpyrophosphate partially reversed it and dolichol had no effect(Ref. 0064).
Dolichyl, dihydroheptaprenyl, and dihydrodecaprenyl phosphates induced apoptosis in U937 cells, while farnesyl phosphate, geranylgeranyl phosphate, dolichol, dolichal, and dlichoic acid did not induce apoptosis. Apoptosis induced by dihydroprenyl phosphate was mediated by caspase-3-like activation but not by caspase-1-like activation(Ref. 0065).

Role of Dol-P in regulation of protein glycosylation in 2- acetylaminofluorene- induced carcinogenesis in rat liver(Ref. 0050). Effect of Dol-P concentration on the formation of lipid-saccharides and the N-glycosylation of protein by thyroid ER vesicles(Ref. 0095). The microsomal fraction of liver has been found to catalyze glucose transfer from UDPG to a lipid acceptor to be identical to the compound obtained by chemical phosphorylation of Dol (Ref. 0096). The biological role of Dol (review) (Ref. 0043). Metabolic labeling of rat liver slices with mevalonic acid revealed the accumulation of E,E,E-geranylgeranyl (di)phosphate as well as dolichyl (di)phosphate (C85 and C90) and dehydrodolichol (C85 and C90), but no accumulation of Z,E,E-geranylgeranyl (di)phosphate or E,E-farnesyl (di)phosphate was detected(Ref. 0026). Dol-P pathway leading to N-glycosylation of protein(Ref. 0097). Content of dolichol and activity of GlcNAc-1-P (UDP-N-acetylglucosamine:dolichyl phosphate N-acetylglucosamine 1-phosphate transferase) in fibroblasts from patients with carbohydrate- deficient- glycoprotein (CDG) syndrome were analyzed. The major defect of CDG syndrome is not found in the synthesys of Dol-P or GlcNAc-PP-Dol(Ref. 0061).
Dolichyl phosphate is a potent inducer of apoptosis in rat glioma cells. Apoptotic changes were also observed in HL-60 cells, SIRC cells and HeLa cells(Ref. 0098). Exogenous dolichyl phosphate induced apoptosis in the human monoblastic leukemia cell line U937 within 4 hours. Dol-P-induced apoptosis is mediated by mitogen-activated protein kinase (MAP kinase) cascade(Ref. 0099). Treatment of U937 cells with dolichyl phosphate led to an increase in the activity of the ICE family protease CPP32, accompanied with cleavage of pre-CPP32 to generate p17. The modulation of cAMP synthesis due to the stimulation of adenylate cyclase by dolichyl phosphate plays a critical role in CPP32 activation and apoptosis(Ref. 0100). Dolichyl, dihydroheptaprenyl, and dihydrodecaprenyl phosphates induced apoptosis in U937 cells, while farnesyl phosphate, geranylgeranyl phosphate, dolichol, dolichal, and dolichoic acid did not induce apoptosis. Apoptosis induced by dihydroprenyl phosphate was mediated by caspase-3-like activation but not by caspase-1-like activation(Ref. 0065).

Effect of Dol-P concentration on the formation of lipid-saccharides and the N-glycosylation of protein by thyroid ER vesicles(Ref. 0095). The microsomal fraction of liver has been found to catalyze glucose transfer from UDPG to a lipid acceptor to be identical to the compound obtained by chemical phosphorylation of Dol (Ref. 0096). The biological role of dolichol (review) (Ref. 0043). Metabolic labeling of rat liver slices with mevalonic acid revealed the accumulation of E,E,E-geranylgeranyl (di)phosphate as well as dolichyl (di)phosphate (C85 and C90) and dehydrodolichol (C85 and C90), but no accumulation of Z,E,E-geranylgeranyl (di)phosphate or E,E-farnesyl (di)phosphate was detected(Ref. 0026).

The biological role of dolichol (review)(Ref. 0043). Dolichyl phosphate is a potent inducer of apoptosis in rat glioma cells. Apoptotic changes were also observed in HL-60 cells, SIRC cells and HeLa cells(Ref. 0098). Treatment of U937 cells with dolichyl phosphate led to an increase in the activity of the ICE family protease CPP32, accompanied with cleavage of pre-CPP32 to generate p17. The modulation od cAMP synthesis due to the stimulation of adenylate cyclase by dolichyl phosphate plays a critical role in CPP32 activation and apoptosis(Ref. 0100).
