Glucose Uptake Assay in Leishmania

Glucose uptake assays employed logarithmic phase L. mexicana promastigotes of the Δlmxgt1-3 hexose transporter null mutant strain expressing either PfHT or GLUT1 from an episomal expression vector [17 (link)]. Parasites (1x107) were resuspended in 100 μL phosphate buffered saline, pH 7.4. Prior to uptake, parasites were pre-incubated for 5 min with inhibitor, and uptake was initiated by adding 100 μL of 200 μM [3H] D-glucose diluted to 4.0 μCi/mL. Uptake was terminated, typically after 1 min, by centrifuging the parasites through a layer of dibutyl phthalate, as described [23 (link)]. Control uptake assays employing [3H] hypoxanthine, [3H] uridine, and [3H] L-proline were performed similarly. Analysis of kinetic data was performed using Graph Pad Prism 4.0b software (Graph Pad).

Statistical Analysis of Tumor Growth and Patient Data

Check if the same lab product or an alternative is used in the 5 most similar protocols
All data (means ± standard error of mean [xenografts] or standard deviation [in vitro]) were analysed using Excel or GraphPad Prism 5. For tumour growth analysis, a parametric generalised linear model was performed using GraphPad Prism 4.0b software. For western blot analysis, cell proliferation and qRT-PCR, statistical significance was determined using the Kruskal-Wallis one-way analysis of variance. All in vitro experiments were replicated on at least three occasions. For patient data, the χ2 test was used to determine association between PAT4 expression and categorical clinical variables (Supplementary Table S1). Cox-regression analysis was employed to determine prognostic factors in univariate (Supplementary Table S2) and multivariate survival models (Supplementary Table S3). The log rank (Mantel-Cox) test was used to assess the significance of differences in relapse-free survival between Kaplan-Meier curves. Statistical analyses were performed using SPSS Statistics (Version 21.0).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
