Steroids and hematopoiesis. III. The response of granulocytic and erythroid colony-forming cells to steroids of different classes. (1/10387)

Selected androgenic and nonandrogenic steroids enhance in vitro granulocytic and erythroid colony formation by mouse marrow cells, but do so by influencing either different target cells or cells in different states of cell cycle. Etiocholanolone, a naturally occurring nonandrogenic testosterone metabolite, permits cells not in active cycle to respond to colony-stimulating factor or erythropoietin. Fluoxymesterone, a synthetic androgen, appears to enhance colony growth by increasing the responsiveness of target cells to tropic stimuli. The majority of cells responding to this androgen are in active DNA synthesis. Direct comparison, however, of etiocholanolone-dependent erythroid or granulocytic colony-forming cells demonstrates nonidentity of the target cells. Thus colony-forming units responding to different classes of steroids are in different states of cell cycle and are physically separable. The enhancement of the in vitro response of colony-forming cells to regulating hormones by steroids such as etiocholanolane suggests a mechanism by which such agents may be therapeutically effective in certain cases of marrow failure in man.

Ambiguity of the thymidine index. (2/10387)

The observed thymidine indices of seven experimental tumor lines are compared as a function of duration of emulsion exposure. The effects of dose level of tritiated thymidine and background threshold are also evaluated. The results indicate that an arbitrary high background threshold discriminates against "lightly" labeled cells at short periods of exposure but that the chosen threshold becomes less critical with longer exposure. The observed thymidine index increases with increasing duration of emulsion exposure but appears to approach a plateau for all tumor systems. The "thymidine index curves" are significantly different for each tumor. There is an inverse relationship between the dose of tritiated thymidine and the duration of exposure required to recognize the same fraction of cells as labeled in a given tumor. Similar experimental conditions do not necessarily guarantee a valid basis for comparison of observed thymidine indices among tumors. (+info)

Energy depletion differently affects membrane transport and intracellular metabolism of riboflavin taken up by isolated rat enterocytes. (3/10387)

Isolated rat enterocytes, both normal and those de-energized with rotenone, were used to study the energy dependence of membrane and intracellular intestinal riboflavin transport in vitro. Membrane and intracellular transport were investigated by using short (3 min) and long (20 min) incubation times, respectively. For both types of cells and incubation times, [3H]-riboflavin uptake presented a saturable component prevailing at physiologic intraluminal concentrations. At 3 min incubation, saturable [3H]-riboflavin transport was apparently an energy-independent process with high affinity and low capacity. Values of the saturable component and its apparent constants, Km and Jmax, did not differ in normal and de-energized enterocytes. At 20 min incubation, saturable [3H]-riboflavin transport was a strictly energy-dependent process in which values of the saturable component were significantly greater in normal than in de-energized enterocytes. Km values did not differ in the two types of cells and were unmodified over 3 min, whereas in normal enterocytes, Jmax at 20 min [6.25 +/- 0.2 pmol/(mg protein. 20 min)] was significantly greater than at 3 min [2.67 +/- 0.33 pmol/(mg protein. 3 min)] and compared with de-energized enterocytes at 20 min [2.54 +/- 0.16 pmol/(mg protein. 20 min)]. Both membrane and intracellular events were inhibited by unlabeled riboflavin and analogs, which are good substrates for flavokinase, thus demonstrating the paramount role of this enzyme in riboflavin intestinal transport.

(S)-(-)-Cotinine, the major brain metabolite of nicotine, stimulates nicotinic receptors to evoke [3H]dopamine release from rat striatal slices in a calcium-dependent manner. (4/10387)

Cotinine, a major peripheral metabolite of nicotine, has recently been shown to be the most abundant metabolite in rat brain after peripheral nicotine administration. However, little attention has been focused on the contribution of cotinine to the pharmacological effects of nicotine exposure in either animals or humans. The present study determined the concentration-response relationship for (S)-(-)-cotinine-evoked 3H overflow from superfused rat striatal slices preloaded with [3H]dopamine ([3H]DA) and whether this response was mediated by nicotinic receptor stimulation. (S)-(-)-Cotinine (1 microM to 3 mM) evoked 3H overflow from [3H]DA-preloaded rat striatal slices in a concentration-dependent manner with an EC50 value of 30 microM, indicating a lower potency than either (S)-(-)-nicotine or the active nicotine metabolite, (S)-(-)-nornicotine. As reported for (S)-(-)-nicotine and (S)-(-)-nornicotine, desensitization to the effect of (S)-(-)-cotinine was observed. The classic nicotinic receptor antagonists mecamylamine and dihydro-beta-erythroidine inhibited the response to (S)-(-)-cotinine (1-100 microM). Additionally, 3H overflow evoked by (S)-(-)-cotinine (10-1000 microM) was inhibited by superfusion with a low calcium buffer. Interestingly, over the same concentration range, (S)-(-)-cotinine did not inhibit [3H]DA uptake into striatal synaptosomes. These results demonstrate that (S)-(-)-cotinine, a constituent of tobacco products and the major metabolite of nicotine, stimulates nicotinic receptors to evoke the release of DA in a calcium-dependent manner from superfused rat striatal slices. Thus, (S)-(-)-cotinine likely contributes to the neuropharmacological effects of nicotine and tobacco use. (+info)

[3H]gemcitabine uptake by nucleoside transporters in a human head and neck squamous carcinoma cell line. (5/10387)

Cellular uptake of many chemotherapeutic nucleoside analogs is dependent on the activity of a family of nucleoside transport proteins located in the cell plasma membrane. In the present study, we examined the role of these transporters in the accumulation of gemcitabine by a human head and neck squamous carcinoma cell line. The uptake of [3H]gemcitibine was compared with that of [3H]uridine and [3H]formycin B in the parent cell line (HN-5a) and in a gemcitabine-resistant variant (GEM-8e). The HN-5a and GEM-8e cells were similar in their transport characteristics and expressed predominantly the es (equilibrative, inhibitor-sensitive) transporter subtype; less than 10% of the influx of [3H]formycin B or [3H]uridine was mediated by the ei (equilibrative inhibitor-resistant) system, and there was no evidence for Na+-dependent nucleoside transporters. [3H]Gemcitabine (10 microM) entered these cells via both the es and ei transporters with an initial rate of uptake similar to that seen with the use of [3H]formycin B or [3H]uridine. In addition, ATP-replete cells accumulated significantly less [3H]gemcitabine than did ATP-depleted cells, which is indicative of an active efflux mechanism for gemcitabine. These results show that gemcitabine is a substrate for both the es and ei nucleoside transporters of HN-5a and GEM-8e cells and that gemcitabine resistance of the GEM-8e cells cannot be attributed to changes in transporter activity. Further studies to define the characteristics of the putative efflux mechanism are clearly warranted because this system has the potential to significantly affect the clinical efficacy of gemcitabine.

Age-related reductions in [3H]WIN 35,428 binding to the dopamine transporter in nigrostriatal and mesolimbic brain regions of the fischer 344 rat. (6/10387)

In the present study, we used the potent cocaine analog [3H]WIN 35, 428 to map and quantify binding to the dopamine transporter (DAT) within the dorsal striatum, nucleus accumbens, substantia nigra, and ventral tegmental area in young (6-month-old), middle-aged (12-month-old), and aged (18- and 24-month-old) Fischer 344 rats. Quantitative autoradiographic analysis of indirect [3H]WIN 35,428 saturation curves revealed two-site binding for all four brain regions in every age group. The percentage of binding to the high- or low-affinity sites did not differ with age or region and was approximately 50%. However, significant age-related decreases in the overall density (Bmax) of [3H]WIN 35,428-binding sites were observed in the striatum, nucleus accumbens, substantia nigra, and ventral tegmental area. The Bmax within all brain regions declined by more than 15% every 6 months, with the Bmax in the aged (24-month-old) group being approximately half that measured in the young adult (6-month-old) group. Competition experiments indicated that nomifensine also exhibited two-site binding to the DAT in Fischer 344 rats. No consistent age-related differences in binding affinities were noted with either [3H]WIN 35,428 or nomifensine. Taken together, these results support the hypothesis that functional DATs within the nigrostriatal and mesolimbic systems are down-regulated with age, without changing their affinity for ligands.

Redundant systems of phosphatidic acid biosynthesis via acylation of glycerol-3-phosphate or dihydroxyacetone phosphate in the yeast Saccharomyces cerevisiae. (7/10387)

In the yeast Saccharomyces cerevisiae lipid particles harbor two acyltransferases, Gat1p and Slc1p, which catalyze subsequent steps of acylation required for the formation of phosphatidic acid. Both enzymes are also components of the endoplasmic reticulum, but this compartment contains additional acyltransferase(s) involved in the biosynthesis of phosphatidic acid (K. Athenstaedt and G. Daum, J. Bacteriol. 179:7611-7616, 1997). Using the gat1 mutant strain TTA1, we show here that Gat1p present in both subcellular fractions accepts glycerol-3-phosphate and dihydroxyacetone phosphate as a substrate. Similarly, the additional acyltransferase(s) present in the endoplasmic reticulum can acylate both precursors. In contrast, yeast mitochondria harbor an enzyme(s) that significantly prefers dihydroxyacetone phosphate as a substrate for acylation, suggesting that at least one additional independent acyltransferase is present in this organelle. Surprisingly, enzymatic activity of 1-acyldihydroxyacetone phosphate reductase, which is required for the conversion of 1-acyldihydroxyacetone phosphate to 1-acylglycerol-3-phosphate (lysophosphatidic acid), is detectable only in lipid particles and the endoplasmic reticulum and not in mitochondria. In vivo labeling of wild-type cells with [2-3H, U-14C]glycerol revealed that both glycerol-3-phosphate and dihydroxyacetone phosphate can be incorporated as a backbone of glycerolipids. In the gat1 mutant and the 1-acylglycerol-3-phosphate acyltransferase slc1 mutant, the dihydroxyacetone phosphate pathway of phosphatidic acid biosynthesis is slightly preferred as compared to the wild type. Thus, mutations of the major acyltransferases Gat1p and Slc1p lead to an increased contribution of mitochondrial acyltransferase(s) to glycerolipid synthesis due to their substrate preference for dihydroxyacetone phosphate.

Homologous regulation of the alpha2C-adrenoceptor subtype in human hepatocarcinoma, HepG2. (8/10387)

1. Previous studies of the regulation of the alpha2C-adrenoceptor in OK and in transfected cells have led to discrepant conclusions. In the present work, we examined the homologous regulation of the human alpha2C-adrenoceptor in the hepatocarcinoma cell-line, HepG2; a model which expresses this subtype spontaneously. 2. Short-period treatment of the cells with UK14304 provoked neither a diminution of the potency of the alpha2-agonist to inhibit forskolin-induced cyclic AMP-accumulation nor a change in the degree of receptor coupling to G-proteins. 3. Long-period exposure to UK14304 resulted in a large reduction of [3H]MK912 binding sites (55% decrease). The action of UK14304 was dose-dependent (EC50 = 190 +/- 45 nM), rapid (t1/2 = 4.2 h) and reversible. Receptor down-regulation was also observed with clonidine or (-)adrenaline (38 and 36% decrease, respectively) and was blocked by the addition of alpha2-antagonists. 4. Conversely to that observed with alpha2-agonists, treatment of the cells with RX821002 or yohimbine alone, but not with phentolamine, promoted a significant increase of the receptor expression. 5. The observed alterations of receptor density are not the reflection of changes at the alpha2C4 mRNA level. Estimation of the receptor protein turnover and measurement of its half-life demonstrated that down-regulation by alpha2-agonists and up-regulation by alpha2-antagonists, with inverse-agonist efficacy, are respectively the consequence of increased and decreased rate of receptor degradation. 6. In conclusion, our data show that alpha2C-adrenoceptor does not undergo desensitization but is down-regulated in HepG2. The lack of desensitization agrees with previous results obtained in cells transfected with the alpha2C4 gene, but not with observations made in OK cells. Inversely, down-regulation fits with results obtained in OK but not in transfected cells. The reasons for these discrepancies are discussed. Our results also demonstrated that certain alpha2-antagonists behave as inverse agonist on the HepG2 model and thus provide for the first time evidence of inverse efficacy of antagonists on a cellular model expressing physiological level of a wild-type alpha2-adrenoceptor.
