In addition to the well-known shift of cancer cells to aerobic glycolysis, mutations or changes in the expression of metabolic enzymes have been identified as potential cancer drivers. We provide evidence that low ALDH7A1 expression is a useful prognostic marker of poor clinical outcome for hepatocellular and renal clear cell carcinomas and hypothesize that patients with low ALDH7A1 might benefit from therapeutic approaches addressing PPARα activity.Ī growing body of evidence links changes in metabolism to cancer. Low ALDH7A1 protein levels correlated with poor clinical outcome in hepatocellular and renal clear cell carcinoma patients. Treatment with a PPARα agonist restored normal cellular behavior. ALDH7A1-depletion led to reduced PPAR transcriptional activity. Metabolic profiling showed that endogenous PPARα ligands were reduced in ALDH7A1-depleted cells. Using pathway and gene set enrichment analysis, we establish a correlation between low ALDH7A1 levels, reduced PPAR signaling and reduced patient survival. Analysis of publically available cancer gene expression data revealed that ALDH7A1 mRNA levels were reduced in many human cancers, and that this correlated with poor survival in kidney and liver cancer patients. Depletion of ALDH7A1 led to reduced levels of metabolites identified as ligands for Peroxisome proliferator-activated receptor (PPARα). Resultsĭepletion of ALDH7A1 increased cellular migration and invasiveness in vitro. Immunohistochemistry was used to assess ALDH7A1 expression in tissue samples from cancer patients. A variety of statistical tests used to evaluate these analyses are described in detail in the methods section. Computational pathway and gene set enrichment analysis was used to identify signaling pathways and cellular processes that were correlated with reduced ALDH7A1 expression in cancer. Publically available cancer gene expression data was interrogated to identify a gene-expression signature associated with depletion of ALDH7A1. 1H-NMR metabolite profiling was used to identify metabolic changes in ALDH7A1-depleted cells. The role of the human ortholog was examined using RNA interference in cell-based assays of cell migration and invasion. MethodsĪLDH7A1 was identified as a potential cancer gene using a Drosophila in vivo metastasis model. Here, we explore the mechanism by which metabolic changes dependent on aldehyde dehydrogenase impact cancer development.

These optimised sequences can then be used in the patient cohort.Changes in cellular metabolism are now recognized as potential drivers of cancer development, rather than as secondary consequences of disease. The healthy volunteers will be scanned for no more than one hour per session for a maximum of two sessions in total. On completion of radiotherapy treatment, the participants will continue to be on standard of care follow up protocol with the treating oncologist.Ī small cohort of ten healthy volunteers will also be recruited to the study to develop and select some of the MR sequences only; they will not provide blood or urine samples. In addition, they will be requested to give weekly blood and urine samples during the course of radiotherapy and at first follow up. The study participants will receive the standard of care treatment for their disease condition. All patients undergoing treatment in the MR Linac at the Christie hospital will be considered for enrolment regardless of tumour site being treated. This enables us to take images with high resolution and target the tumours more precisely and also reduce the dose to normal tissues. The MR Linac is a new radiotherapy machine with an on board MR scanner. The overarching hypothesis is that changes in MR imaging and biological parameters from blood, tissue, or urine biomarkers can be measured during radiotherapy and associated with clinical outcome. This is accomplished by studying the MR images taken during each treatment session on the MR Linear accelerator (MR Linac). The MR BIO study aims to understand the changes in the tumour and normal tissues during a course of radiotherapy. Why Should I Register and Submit Results?.
