Cell growth inhibition by farnesyltransferase inhibitors is mediated by gain of geranylgeranylated RhoB. (1/5837)Recent results have shown that the ability of farnesyltransferase inhibitors (FTIs) to inhibit malignant cell transformation and Ras prenylation can be separated. We proposed previously that farnesylated Rho proteins are important targets for alternation by FTIs, based on studies of RhoB (the FTI-Rho hypothesis). Cells treated with FTIs exhibit a loss of farnesylated RhoB but a gain of geranylgeranylated RhoB (RhoB-GG), which is associated with loss of growth-promoting activity. In this study, we tested whether the gain of RhoB-GG elicited by FTI treatment was sufficient to mediate FTI-induced cell growth inhibition. In support of this hypothesis, when expressed in Ras-transformed cells RhoB-GG induced phenotypic reversion, cell growth inhibition, and activation of the cell cycle kinase inhibitor p21WAF1. RhoB-GG did not affect the phenotype or growth of normal cells. These effects were similar to FTI treatment insofar as they were all induced in transformed cells but not in normal cells. RhoB-GG did not promote anoikis of Ras-transformed cells, implying that this response to FTIs involves loss-of-function effects. Our findings corroborate the FTI-Rho hypothesis and demonstrate that gain-of-function effects on Rho are part of the drug mechanism. Gain of RhoB-GG may explain how FTIs inhibit the growth of human tumor cells that lack Ras mutations. (+info)
Hsp60 is targeted to a cryptic mitochondrion-derived organelle ("crypton") in the microaerophilic protozoan parasite Entamoeba histolytica. (2/5837)Entamoeba histolytica is a microaerophilic protozoan parasite in which neither mitochondria nor mitochondrion-derived organelles have been previously observed. Recently, a segment of an E. histolytica gene was identified that encoded a protein similar to the mitochondrial 60-kDa heat shock protein (Hsp60 or chaperonin 60), which refolds nuclear-encoded proteins after passage through organellar membranes. The possible function and localization of the amebic Hsp60 were explored here. Like Hsp60 of mitochondria, amebic Hsp60 RNA and protein were both strongly induced by incubating parasites at 42 degreesC. 5' and 3' rapid amplifications of cDNA ends were used to obtain the entire E. histolytica hsp60 coding region, which predicted a 536-amino-acid Hsp60. The E. histolytica hsp60 gene protected from heat shock Escherichia coli groEL mutants, demonstrating the chaperonin function of the amebic Hsp60. The E. histolytica Hsp60, which lacked characteristic carboxy-terminal Gly-Met repeats, had a 21-amino-acid amino-terminal, organelle-targeting presequence that was cleaved in vivo. This presequence was necessary to target Hsp60 to one (and occasionally two or three) short, cylindrical organelle(s). In contrast, amebic alcohol dehydrogenase 1 and ferredoxin, which are bacteria-like enzymes, were diffusely distributed throughout the cytosol. We suggest that the Hsp60-associated, mitochondrion-derived organelle identified here be named "crypton," as its structure was previously hidden and its function is still cryptic. (+info)
The biosynthesis of transfer RNA in insects. II. Isolation of transfer RNA precursors from the posterior silk gland of Bombyx mori. (3/5837)The occurrence of precursors to tRNA in the post-polysomal fraction of the posterior silk gland of Bombyx mori was demonstrated by pulse-chase labeling and DNA-RNA hybridization competition experiments. These precursors had molecular sizes ranging from 4S to 5S on polyacrylamide gel electrophoresis. Analysis of the incorporation of the methyl group from [methyl-14C]methionine revealed that a radioactive peak on polyacrylamide gel appeared in the 4.5S region during brief labeling. This suggested that some methylation occurred at the 4.5S precursor step. (+info)
Purification and characterization of initiation factor IF-E2 from rabbit reticulocytes. (4/5837)Initiation factor IF-E2 was isolated from rabbit reticulocytes and purified 120-fold to near homogeneity by ammonium sulfate fractionation, column chromatography on DEAE-cellulose and phosphocellulose, and, when suitable, by sucrose density gradient centrifugation. The factor is a complex protein containing three nonidentical polypeptides of molecular weight 57,000, 52,000, and 36,000. It behaves as a complex throughout its purification and during polyacrylamide gel electrophoresis in nondenaturing buffer but its thress components are readily separated by electrophoresis in denaturing buffers. None of its components corresponds to any of the polypeptides of the other initiation factors or to any proteins of ribosomes washed in buffers containing a high salf concentration. A stoichiometric ratio of 1:1:1 was determined for the three polypeptides; based on the assumption of one copy each per complex, the calculated factor molecular weight is 145,000, a value in agreement with the measured value of 160,000. Initiation factor IF-E2 was radioactively labeled in vitro by reductive alkylation or by phosphorylation with a protein kinase also isolated from rabbit reticulocytes. Neither procedure causes a measurable change in the ability of the factor to form a ternary complex with GTP and the initiator methionyl-tRNA. 5'-Guanylyl-methylenediphosphonate may substitute for GTP, but only at relatively high concentrations. The binding of labeled initiation factor IF-E2 and methionyl-tRNA to the 40 S ribosomal subunit was studied by sucrose density gradient centrifugation. Appreciable binding of the factor is seen only when all three components of the ternary complex are included in the reaction mixture. The binding of either the factor or methionyl-tRNA was not stimulated by the addition of globin messenger RNA and initiation factor IF-E3. It was shown that all three polypeptide components of initiation factor IF-E2 are bound to these nascent initiation complexes. (+info)
Endothelial dysfunction by acute hyperhomocyst(e)inaemia: restoration by folic acid. (5/5837)Recent evidence demonstrates that hyperhomocyst(e)inaemia is a novel risk factor for cardiovascular diseases. In patients with chronic hyperhomocyst(e)inaemia, endothelial function is impaired. However, whether hyperhomocyst(e)inaemia per se is a cause or an epiphenomenon of endothelial dysfunction remains unknown. In this study, we examined the effects of methionine-induced acute hyperhomocyst(e)inaemia on human endothelial function. In healthy volunteers we administered methionine (0.1 g/kg body weight, per os), a substrate of homocyst(e)ine, with or without folic acid (20 mg, per os) and examined flow-mediated vasodilatation of the brachial artery by high-resolution ultrasonography as a non-invasive measure of endothelial function. We also measured plasma levels of homocyst(e)ine before and 3, 8 and 24 h after methionine loading. Methionine administration increased plasma levels of homocyst(e)ine by four times the basal level at 8 h (P<0.0001, ANOVA). The plasma levels returned to baseline at 24 h. Flow-mediated vasodilatation was significantly decreased to half of the baseline value at 8 h and returned to baseline at 24 h (P<0.0001, ANOVA), whereas endothelium-independent vasodilatation by glyceryl trinitrate was not affected by the methionine loading. Co-administration of folic acid did not attenuate methionine-induced hyperhomocyst(e)inaemia but completely prevented endothelial dysfunction. Our results suggest that in humans a methionine-rich diet may acutely impair endothelial function, which can be prevented by folic acid supplementation. (+info)
cAMP inhibits translation by inducing Ca2+/calmodulin-independent elongation factor 2 kinase activity in IPC-81 cells. (6/5837)Treatment of IPC-81 cells led to inhibition of protein synthesis, which was accompanied by an increase in the average size of polysomes and a decreased rate of elongation, indicating that it involved inhibition of peptide chain elongation. This inhibition was also associated with increased phosphorylation of elongation factor eEF2 (which inhibits its activity) and enhanced Ca2+/calmodulin-independent activity of eEF2 kinase. Previous work has shown that phosphorylation of eEF2 kinase by cAMP-dependent protein kinase (cAPK) in vitro induces such activator-independent activity, and the present data show that such a mechanism can occur in intact cells to link physiological levels of cAPK activation with inhibition of protein synthesis.

Insulin and TSH promote growth in size of PC Cl3 rat thyroid cells, possibly via a pathway different from DNA synthesis: comparison with FRTL-5 cells. (7/5837)In the rat thyroid cell lines PC Cl3, FRTL- 5 and WRT, proliferation is mainly regulated by insulin or IGF, and TSH. However, the mechanism regulating cell mass doubling prior to division is still unknown. Our laboratory has shown that in dog thyroid cells insulin promotes growth in size while TSH in the presence of insulin triggers DNA replication. In the absence of insulin, TSH has no effect on cell growth. In this report we investigated insulin action on both cell mass and DNA synthesis and its modulation by TSH and insulin in PC Cl3 and FRTL-5 cells. In PC Cl3 cells, insulin activated not only DNA synthesis but also protein synthesis and accumulation. Although TSH potentiated the stimulation of DNA synthesis induced by insulin, enhancement of protein synthesis by both agents was additive. All TSH effects were reproduced by forskolin. Similar effects were also obtained in FRTL-5 cells. This suggests that insulin and TSH, via cAMP, modulate both growth in size and DNA replication in these cell lines. Lovastatin, which blocks 3-hydroxy-3-methylglutaryl coenzyme A reductase, decreased the induction of DNA synthesis, but not of protein synthesis induced by insulin or TSH in PC Cl3 cells. In FRTL-5 cells, lovastatin reduced protein and DNA synthesis stimulated by insulin but not TSH-induced protein synthesis. Taking these data together, we propose that insulin and/or TSH both modulate cell mass doubling and DNA synthesis in these cell lines, presumably via different pathways, and that there are at least two pathways which regulate growth in size in FRTL-5 thyroid cells: one triggered by insulin, which is lovastatin sensitive, and the other activated by TSH, which is not sensitive to lovastatin.

Is human thioredoxin monomeric or dimeric? (8/5837)We have examined the molecular weight and rotational correlation time of human thioredoxin by analytical ultracentrifugation and NMR spectroscopy, respectively. Two variants of human thioredoxin were studied, namely human thioredoxin identical in amino acid sequence to the one whose NMR structure we previously determined (C62A, C69A, C73A, M74T) and human thioredoxin (C62A, C69A, C73A, M74) containing the wild-type amino acid methionine at position 74. In both cases, the experimental data indicate that the predominant species is monomeric and we find no evidence for the existence of a well-defined dimeric form as was observed in the recently reported crystal structure (Weichsel et al., 1996) of human thioredoxin and the C73S mutant.

Treatment for homocystinuria typically involves a combination of dietary modifications and nutritional supplements to manage the symptoms and prevent long-term complications. In some cases, medication may also be prescribed to reduce the levels of homocysteine in the blood.
The prognosis for individuals with homocystinuria varies depending on the severity of the condition and the effectiveness of treatment. Some individuals with mild forms of the disorder may experience few or no symptoms, while those with more severe forms may have significant developmental delays and disabilities. With appropriate management, however, many individuals with homocystinuria can lead active and fulfilling lives.
There are several factors that can contribute to hyperhomocysteinemia, including:
1. Genetic mutations: Some individuals may have genetic mutations that affect the enzymes involved in homocysteine metabolism, leading to elevated levels of homocysteine.
2. Vitamin deficiencies: Deficiencies in vitamins B6, B12, and folate can interfere with the metabolism of homocysteine, leading to elevated levels.
3. Kidney disease: The kidneys play a critical role in removing homocysteine from the body. Any damage to the kidneys or impairment in their function can lead to hyperhomocysteinemia.
4. Other medical conditions: Certain medical conditions, such as thyroid disorders and autoimmune diseases, can also contribute to hyperhomocysteinemia.
Elevated levels of homocysteine have been linked to several health problems, including:
1. Cardiovascular disease: High levels of homocysteine have been associated with an increased risk of heart disease and stroke.
2. Blood clots: Homocysteine can interfere with the normal blood clotting process, leading to an increased risk of blood clots and deep vein thrombosis.
3. Bone loss: Elevated levels of homocysteine have been linked to bone loss and an increased risk of osteoporosis.
4. Cognitive decline: Some studies suggest that high levels of homocysteine may be associated with cognitive decline and an increased risk of dementia.
Treatment for hyperhomocysteinemia typically involves addressing any underlying medical conditions, such as kidney disease or thyroid disorders, and making dietary changes to increase the intake of vitamin B6, folate, and other nutrients that help regulate homocysteine levels. In some cases, medications may be prescribed to lower homocysteine levels. Regular monitoring of homocysteine levels can help healthcare providers track the effectiveness of treatment and make any necessary adjustments.
Choline deficiency can cause a range of health problems, including:
1. Fatty liver disease: Choline is important for the transport of fat from the liver to other parts of the body, and a deficiency can lead to fat accumulation in the liver, which can cause fatty liver disease.
2. Brain function problems: Choline is crucial for the synthesis of the neurotransmitter acetylcholine, which is involved in memory, attention, and cognitive function. A deficiency can lead to problems with brain development and function.
3. Mood disorders: Low choline levels have been linked to an increased risk of depression and anxiety.
4. Insulin resistance: Choline helps regulate glucose metabolism, and a deficiency can lead to insulin resistance, which can increase the risk of developing type 2 diabetes.
5. Skin and eye problems: Choline is important for the health of the skin and eyes, and a deficiency can lead to conditions such as acne, eczema, and dry eye syndrome.
6. Reproductive problems: Choline is important for fertility and fetal development during pregnancy, and a deficiency can increase the risk of miscarriage, birth defects, and preterm labor.
If you suspect that you or your child may have a choline deficiency, it's important to speak with a healthcare provider who can perform tests to determine if low choline levels are causing any health problems. Treatment for choline deficiency typically involves dietary changes and supplementation with choline-rich foods or supplements.
* Dietary deficiency due to a lack of animal products in the diet
* Malabsorption due to gastrointestinal disorders such as Crohn's disease or celiac disease
* Pernicious anemia, an autoimmune condition that affects the absorption of vitamin B12 in the gut.
* Surgical removal of part of the small intestine
* Certain medications such as metformin and proton pump inhibitors
* Fatigue, weakness, and shortness of breath
* Pale skin and mouth sores
* Difficulty walking or balance problems
* Numbness or tingling sensations in the hands and feet
* Memory loss and depression
* Poor appetite and weight loss
* Blood tests to measure vitamin B12 levels and other related markers such as homocysteine
* Physical examination and medical history to identify risk factors or signs of deficiency
* Dietary changes to include more animal products such as meat, fish, eggs, and dairy products.
* Vitamin B12 supplements in the form of tablets, lozenges, or injections.
* Addressing underlying conditions that may be contributing to the deficiency such as gastrointestinal disorders.
* Consuming animal products as part of a balanced diet
* Avoiding medications that can interfere with vitamin B12 absorption.
1. Anemia: Folic acid plays a critical role in the production of red blood cells, so a deficiency can lead to anemia, which can cause fatigue, weakness, and shortness of breath.
2. Birth defects: Folic acid is crucial for fetal development during pregnancy, and a deficiency can increase the risk of birth defects such as spina bifida and cleft palate.
3. Heart disease: Folic acid helps to regulate homocysteine levels in the blood, which are associated with an increased risk of heart disease and stroke.
4. Neurological problems: Folic acid is important for the health of the nervous system, and a deficiency can lead to neurological problems such as cognitive impairment, mood disturbances, and seizures.
5. Poor wound healing: Folic acid is necessary for the production of collagen, which is important for wound healing. A deficiency can lead to slow or poor wound healing.
6. Increased risk of cancer: Some studies suggest that a folic acid deficiency may increase the risk of certain types of cancer, such as colon cancer.
7. Hair loss: Folic acid is important for hair growth, and a deficiency can lead to hair loss.
8. Skin problems: Folic acid is important for skin health, and a deficiency can lead to skin problems such as dry, flaky skin and mouth sores.
9. Mood changes: Folic acid plays a role in the production of neurotransmitters, which are chemicals that regulate mood. A deficiency can lead to mood changes such as depression and anxiety.
10. Fatigue: Folic acid is important for energy metabolism, and a deficiency can lead to fatigue and weakness.
Folic acid deficiency can be caused by a number of factors, including:
1. Poor diet: A diet that is low in folate-rich foods can lead to a deficiency.
2. Malabsorption: Certain medical conditions such as celiac disease and Crohn's disease can lead to malabsorption of folic acid.
3. Pregnancy and lactation: Women who are pregnant or breastfeeding have a higher need for folic acid, and may be at risk for deficiency if they do not consume enough.
4. Alcoholism: Heavy alcohol consumption can interfere with the absorption of folic acid.
5. Certain medications: Some medications, such as antacids and proton pump inhibitors, can interfere with the absorption of folic acid.
To diagnose a folic acid deficiency, a healthcare provider may perform a physical exam, take a medical history, and order blood tests to measure folic acid levels. Treatment for a folic acid deficiency typically involves dietary changes and supplements. Dietary changes may include consuming more folate-rich foods, such as leafy green vegetables, legumes, and whole grains. Supplements may include folic acid tablets or liquid supplements. In severe cases of deficiency, injections of folic acid may be necessary. It is important to seek medical attention if you suspect a folic acid deficiency, as untreated deficiencies can lead to serious health problems.
