The cholesterol metabolism is essential for cancer cell proliferation. We found the expression of genes involved in the cholesterol biosynthesis pathway up-regulated in the daunorubicin-resistant leukemia cell line CEM/R2, which is a daughter cell line to the leukemia cell line CCRF-CEM (CEM). Cellular 2H2O labelling, mass spectrometry, and isotopomer analysis revealed an increase in lanosterol synthesis...
Assessment of a biological system by means of global and non-targeted metabolite profiling—metabolomics or metabonomics—provides the investigator with molecular information that is close to the phenotype in question in the sense that metabolites are an ultimate product of gene, mRNA, and protein activity. Over the last few years, there has been a rapidly growing number of metabolomics applications...
