The metabolic alterations of both host and tumor cells are predominantly caused by changes in the glucose metabolism of tumors, higher energy expenditures, decreases in ATP levels and increases in lactic acid production (<a class="elsevierStyleCrossRefs" href="#bib1">1,2</a>).</p><p id="para20" class="elsevierStylePara elsevierViewall">Cellular amino acid contents appear to be essential for tumor growth. Theuer (<a class="elsevierStyleCrossRef" href="#bib3">3</a>) observed that the restriction of tryptophan, threonine, leucine, methionine, phenylalanine, valine and isoleucine contributed to the control of tumor growth in rats. However, host weight was affected by tryptophan, threonine, leucine and methionine restriction. The restriction of phenylalanine and tyrosine also reduced weight, causing a loss of fat and lean body mass and an increase in white cells and neutrophils (<a class="elsevierStyleCrossRef" href="#bib4">4</a>).</p><p id="para30" class="elsevierStylePara elsevierViewall">Although it has been postulated that tumors utilize more amino acids than normal cells, few studies have compared the proportions of amino acids in tumor cells and paired normal tissues. Thus, the objective of the present study was to compare the amino acid content in malignant and adjacent normal tissues from the same patient.</p></span><span id="cesec20" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle20">METHODS</span><p id="para40" class="elsevierStylePara elsevierViewall">The study protocol was approved by the Ethics Committee of the University Hospital of the School of Medicine of Ribeirão Preto, and a signed informed consent form was obtained from all of the study participants. Patients diagnosed with squamous cell carcinoma of the larynx and oral cavity undergoing tumor resection surgery were enrolled in the study. Data collection occurred from August 2006 to July 2007 at the University Hospital, Ribeirão Preto, São Paulo, Brazil.</p><p id="para50" class="elsevierStylePara elsevierViewall">Samples were obtained immediately after tumor removal. Macroscopic tumor samples were collected as far as possible from the necrosis area, and normal samples were collected as far as possible from the neoplastic area. Sample collection was not performed in patients with macroscopically reduced resections. After tissue collection, the samples were weighed (BEL Engineering™) and stored at -20°C for amino acid concentration analysis using gas chromatography with a flame ionization detector. These analyses were performed at the Mass Spectrometry Laboratory of the Department of Internal Medicine of the School of Medicine of the University of São Paulo at Ribeirão Preto.</p><p id="para60" class="elsevierStylePara elsevierViewall">Due to the low quantities of sample tissue tested, amino acid extraction was performed in combination with lipid extraction, using the method of Bligh & Dyer (<a class="elsevierStyleCrossRef" href="#bib5">5</a>). In this process, 50 mg of tissue was homogenized for 5 minutes with 1 mL of chloroform-methanol solution (2:1), and distilled water was added to the solution in a volume that corresponded to 20% of the sample volume. The preparation was then once again homogenized for 5 minutes, and the resultant solution was centrifuged at 1000 rpm for 5 minutes to separate the chloroform (lower) and aqueous (upper) phases. Because amino acids are water soluble, the upper phase was used for the free amino acid analysis. This analysis involved chloroformate derivatization (<a class="elsevierStyleCrossRef" href="#bib6">6</a>) and was conducted as described previously (<a class="elsevierStyleCrossRef" href="#bib7">7</a>). Gas chromatography (Shimadzu™ GC–17A) analysis was conducted under the following conditions: injector temperature, 300°C; detector temperature, 320°C; oven temperature, 110°C, increasing to 320°C at 0.5/minute; column pressure, 60 KPa; and a split ratio of 1:20.</p><p id="para70" class="elsevierStylePara elsevierViewall">The statistical analyses were performed using STATISTICA 8.0 (StatSoft, Inc., Tulsa, OK, USA). The Student's t-test was used to compare the mean±SD amino acid concentrations of malignant and normal larynx tissues (<a class="elsevierStyleCrossRef" href="#tbl1">Table 1</a>), malignant and normal oral tissues (<a class="elsevierStyleCrossRef" href="#tbl2">Table 2</a>), malignant larynx and oral tissues (<a class="elsevierStyleCrossRef" href="#tbl3">Table 3</a>), and normal larynx and oral tissues (<a class="elsevierStyleCrossRef" href="#tbl3">Table 3</a>). A post-hoc power analysis was performed to assess the data validity and sample size power.

The average weights of the tumor and normal tissue samples from the remaining 15 patients were 417±323 mg and 304±207 mg, respectively. The surgical margins of six samples were invaded by the tumor. After excluding these samples, we analyzed six samples of larynx lesions and nine samples from the following sites: the tongue, the floor of the mouth and the lip.</p><p id="para100" class="elsevierStylePara elsevierViewall">The larynx squamous cell carcinomas possessed higher concentrations of threonine, valine, serine, aspartate, glutamate and glycine compared with the surrounding normal tissues (<a class="elsevierStyleCrossRef" href="#tbl1">Table 1</a>). By contrast, there were no differences between the malignant and normal oral tissues (<a class="elsevierStyleCrossRef" href="#tbl2">Table 2</a>). The malignant oral tissues had lower concentrations of glycine, valine and isoleucine compared with the malignant larynx tissues.

We used the normal tissue that surrounded sampled tumors as internal controls. The comparison of tissues from the same patient eliminates interference from factors such as diet, liver function, weight loss, and tumor site and stage.</p><p id="para120" class="elsevierStylePara elsevierViewall">No differences were detected between oral malignant squamous cell carcinomas and surrounding normal tissues (<a class="elsevierStyleCrossRef" href="#tbl2">Table 2</a>). Although the tissue type was the same for each tumor that was examined (squamous cells), each of these oral cavity lesions was located at a different site of the tongue, the floor of the mouth or the lip. Thus, the results with respect to oral cavity samples may have been affected by the heterogeneity of the samples.</p><p id="para130" class="elsevierStylePara elsevierViewall">Higher concentrations of threonine, valine, serine, aspartate, glutamate and glycine were detected in the malignant larynx tissue samples than in the surrounding normal tissues (<a class="elsevierStyleCrossRef" href="#tbl1">Table 1</a>). According to Hagmüller et al. (<a class="elsevierStyleCrossRef" href="#bib8">8</a>), comparisons of amino acids in tumor and normal tissues should consider that the observed concentrations are indicators of dynamic turnover status. Thus, our results may indicate either that tumor cells have a higher amino acid biosynthesis rate (<a class="elsevierStyleCrossRef" href="#bib1">1</a>) or that tumor cells utilize more amino acids as sources of energy (<a class="elsevierStyleCrossRef" href="#bib8">8</a>). However, given the anaerobic conditions of tumor cells, the oxidation of amino acids in these cells is minimal (<a class="elsevierStyleCrossRef" href="#bib2">2</a>), although it has been well established that all of the areas of a tumor that are highly glycolytic are not necessarily hypoxic (<a class="elsevierStyleCrossRef" href="#bib9">9</a>). The quantification of tricarboxylic acid (TCA) cycle intermediates should better explain these results.</p><p id="para140" class="elsevierStylePara elsevierViewall">A previous <span class="elsevierStyleItalic">in vitro</span> study demonstrated the accumulation of alanine, aspartate and glutamate in malignant cells in the presence of oxygen; under anaerobic conditions, however, a decrease in alanine levels and an increase in glutamine concentrations was observed (<a class="elsevierStyleCrossRef" href="#bib10">10</a>). The present data indicate that, compared with normal tissues, malignant tissues have higher concentrations of glutamate and aspartate but similar alanine concentrations. Although it is believed that tumor cells consume large amounts of glutamine to replenish the TCA cycle (<a class="elsevierStyleCrossRef" href="#bib1">1</a>), an <span class="elsevierStyleItalic">in vitro</span> study in head and neck squamous cell carcinoma cell lines revealed that glutamine is not the main energy source for these cells (<a class="elsevierStyleCrossRef" href="#bib11">11</a>). No interpretations can be drawn from this study with respect to glutaminolysis because glutamine was not quantified due to its coelution with other amino acids.</p><p id="para150" class="elsevierStylePara elsevierViewall">Despite the small sample size of this study, post-hoc power analyses produced values higher than 70% for all of the amino acids that differed significantly between squamous cell carcinomas and normal larynx tissues (threonine, valine, serine, aspartate, glutamate and glycine). Therefore, we recommend that amino acid statuses should be assessed in cancer patients because the nutrition of tumor cells is influenced by the nutrition of their host. In addition, further studies are needed to assess the effects of attempts to control tumor proliferation by limiting the dietary consumption of certain essential amino acids, such as threonine and valine.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:6 [ 0 => array:2 [ "identificador" => "cesec10" "titulo" => "INTRODUCTION" ] 1 => array:2 [ "identificador" => "cesec20" "titulo" => "METHODS" ] 2 => array:2 [ "identificador" => "cesec30" "titulo" => "RESULTS" ] 3 => array:2 [ "identificador" => "cesec40" "titulo" => "DISCUSSION" ] 4 => array:2 [ "identificador" => "xack639511" "titulo" => "ACKNOWLEDGMENTS" ] 5 => array:1 [ "titulo" => "REFERENCES" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "NotaPie" => array:1 [ 0 => array:1 [ "nota" => "<p class="elsevierStyleNotepara" id="cenpara10">No potential conflict of interest was reported.</p> <p class="elsevierStyleNotepara" id="cenpara20">Leme IA and Rosa FT were responsible for tissue sample collection and analysis, data interpretation, and drafting the manuscript.
