Abstract
Background Ascorbic acid (AA), or Vitamin C, is most well known as a nutritional supplement with antioxidant properties. Recently, we demonstrated that high concentrations of AA act on PMP22 gene expression and partially correct the Charcot-Marie-Tooth disease phenotype in a mouse model. This is due to the capacity of AA, but not other antioxidants, to down-modulate cAMP intracellular concentration by a competitive inhibition of the adenylate cyclase enzymatic activity. Because of the critical role of cAMP in intracellular signalling, we decided to explore the possibility that ascorbic acid could modulate the expression of other genes. Methods and Findings Using human pangenomic microarrays, we found that AA inhibited the expression of two categories of genes necessary for cell cycle progression, tRNA synthetases and translation initiation factor subunits. In in vitro assays, we demonstrated that AA induced the S-phase arrest of proliferative normal and tumor cells. Highest concentrations of AA leaded to necrotic cell death. However, quiescent cells were not susceptible to AA toxicity, suggesting the blockage of protein synthesis was mainly detrimental in metabolically-active cells. Using animal models, we found that high concentrations of AA inhibited tumor progression in nude mice grafted with HT29 cells (derived from human colon carcinoma). Consistently, expression of tRNA synthetases and ieF2 appeared to be specifically decreased in tumors upon AA treatment. Conclusions AA has an antiproliferative activity, at elevated concentration that could be obtained using IV injection. This activity has been observed in vitro as well in vivo and likely results from the inhibition of expression of genes involved in protein synthesis. Implications for a clinical use in anticancer therapies will be discussed.

Abstract
Subcellular distribution of aminoacyl-tRNA synthetase activities has been studied in normal rabbit liver and under experimental myocardial ischemia (EMI). An increase in the activity of a number of aminoacyl-tRNA synthetases in postmitochondrial and postribosomal supernatants from rabbit liver has been determined 12 hr after EMI. Gel chromatography of the postribosomal supernatant on Sepharose 6B shows that aminoacyl-tRNA synthetase activities are distributed among the fractions with M(r) 1.82 x 10(6), 0.84 x 10(6) (high-M(r) aminoacyl-tRNA synthetase complexes) and 0.12-0.35 x 10(6). In the case of EMI aminoacyl-tRNA synthetase activities are partly redistributed from the 1.82 x 10(6) complex into the 0.84 x 10(6) complex. The catalytic properties of both free and complex leucyl-tRNA synthetases have been compared. KM for all the substrates are the values of the same order in norm and under EMI. A decrease in some aminoacyl-tRNA synthetase activities associated with polyribosomes has been observed 12 hr after EMI. The interaction of aminoacyl-tRNA synthetases with polyribosomes stimulates the catalytic activity of some enzymes and protects them from heat inactivation in vitro. It is assumed that the changes in association of aminoacyl-tRNA synthetases with high-M(r) complexes and compartmentalization of these enzymes on polyribosomes may be related to the alteration of protein biosynthesis under myocardial ischemia.

Abstract
The methodologies described in this chapter allow the reproducible preparation of native high-molecular-weight synthetase complexes of leuRL. These complexes have the ability to preferentially utilize extracellular leucine immediately upon transport and are likely the forms of the enzyme most important in the utilization of leucine for protein synthesis.

Abstract
The tRNA content and aminoacyl-tRNA synthetases of regenerating liver in the phase of rapid growth were compared with those of livers from both intact and sham-operated rats. At 48 h after hepatectomy, the amount of active tRNA (called 'total acceptor capacity') is significantly higher in regenerating liver than in control livers, owing to a general, possibly not uniform, increase in the various tRNA families, which suggests that it may contribute to the increased protein synthesis and to decreased protein degradation as well. The activities of most, but not of all, aminoacyl-tRNA synthetases in cell sap of regenerating liver tend to be greater than normal. Increased activity of histidyl-tRNA synthetase fits in with the possibility that the mechanisms that control the rate of protein degradation through aminoacylation of tRNAHis in cultured cells [Scornik (1983) J. Biol. Chem. 258, 882-886] also operate in the liver and play a role in regeneration. Sedimentation analysis of cell sap in sucrose density gradients shows a shift of prolyl-tRNA synthetase activity toward the high-Mr form in regenerating liver. This change might be related to the positive protein balance and to growth in vivo, since it is also observed in the anaplastic Yoshida ascites hepatoma AH 130.

Abstract
The size distribution of the 20 aminoacyl-tRNA synthetases from wild-type Chinese hamster ovary (CHO) cells and from the mutant cell line tsH1, containing a temperature-sensitive leucyl-tRNA synthetase, was determined by gel filtration. Nine aminoacyl-tRNA synthetases, specific for arginine, aspartic acid, glutamic acid, glutamine, isoleucine, leucine, lysine, methionine and proline, which coeluted as high-Mr entities (Mr approximately 1.2 X 10(6)), were further co-purified to yield a multienzyme complex, the polypeptide composition of which was identical to that previously determined for the complex from rabbit liver. Immunoprecipitates obtained from crude extracts of wild-type and tsH1 mutant cells, using specific antibodies directed to the lysyl-tRNA or methionyl-tRNA synthetase components of the complex, displayed the same polypeptide compositions as that of the purified complex, thereby establishing the heterotypic nature of this complex. Although the activity of leucyl-tRNA synthetase from the mutant cells, grown at a permissive temperature, was low compared to that from the wild-type, the polypeptide of Mr 129 000, corresponding to this enzyme, was present in similar amounts and occurred exclusively as a component of the high-Mr complex. Finally, we report that attempts to demonstrate phosphorylation of the components of the complex from cultured CHO, HeLa and C3 cells were unsuccessful.

Abstract
We have isolated interspecific somatic cell hybrids between a temperature-sensitive Chinese hamster ovary (CHO) cell methioninyl -tRNA synthetase mutant and human peripheral leukocytes. The hybrids were selected at 39 degrees C which requires the retention and expression of the human gene, MARS , which complements the defective CHO gene. In vitro heat-inactivation experiments on the methioninyl -tRNA synthetase activity in cell-free extracts from heat-resistant hybrids indicate that the human form of this enzyme and, therefore, the human MARS gene is present in hybrid cells. Cytogenetic analysis of three independent temperature-resistant hybrids revealed the presence of a single human chromosome, number 12. Two other independent hybrids examined contained human chromosome 12 as well as a second human chromosome. Electrophoretic analysis of extracts from hybrid cell lines for a human chromosome 12 marker isozyme, LDH-B, showed a pattern of heterotetrameric bands consistent with the presence of the human form of this enzyme in these cells. The correlation between the presence of the human form of methioninyl -tRNA synthetase and human chromosome 12 in temperature-resistant hybrids indicates that the human MARS locus is located on this chromosome.

Abstract
The Chinese hamster ovary (CHO) aminoacyl-tRNA synthetase mutants Gln-2, His-1, and Lys-101 were analyzed for alterations in respective particulate enzyme forms. The mutant Gln-2 showed a preferential loss of the lower molecular weight enzyme form for glutamine. His-1 showed alterations of the enzyme complexes for several other aminoacyl-tRNA activities but only decreased activity for itself. The mutant Lys-101 only showed an altered Lysyl-tRNA synthetase. These results provide evidence for a model of the intracellular role of the aminoacyl-tRNA synthetase complexes wherein the high molecular weight forms utilize amino acids directly from the extracellular pool while the low molecular weight forms utilize intracellular pools.

Abstract
A direct correlation was found to exist between increased thermolability of leucyl-tRNA synthetase and loss of the high-molecular-weight enzyme complexes in the CHO cell mutant tsH1 and its revertants. This was shown to occur apart from a differential thermostability between the complexes themselves and is supported by Michaelis constant determinations.

Abstract
The aminoacyl-tRNA synthetases of the postribosomal supernatant fraction of rat skeletal muscle were characterized by their activity and sedimentation properties. The synthetases of muscle were compared with those of liver in terms of these parameters. Extraction of the synthetases of muscle with a buffer containing 4 mM adenosine triphosphate (ATP) resulted in a 50--100% increase in the activities of glutaminyl-, glutamyl-, isoleucyl-, leucyl-, lysyl-, methionyl-, and prolyl-tRNA synthetases in the postribosomal fraction, over those activities extracted in the absence of ATP. This effect of ATP was specific for those synthetases which sedimented as particulate elements in sucrose gradients, and appeared to be unique to muscle. The individual synthetase activities of muscle, except alanyl-, leucyl-, and valyl-tRNA synthetases, were aprrox. 25% of the corresponding synthetase activities of liver. Sucrose density gradient analysis of the postribosomal fraction of muscle and liver revealed that the sedimentation profiles of the synthetases of the two tissues were similar, with nine synthetase activities sedimenting as large particulate entities at 18 S. The findings suggest that the particulate forms of the synthetases reflect true association of the enzymes with a high molecular weight cellular component common to both tissues.
