Abstract

Mycoplasma contamination is a common problem in cell culture and can alter cellular functions Since cell metabolism is either directly or indirectly involved in every aspect of cell function it is important to detect changes to the cellular metabolome after mycoplasma infection In this study liquid chromatography mass spectrometry LC/MSbased metabolomics was used to investigate the effect of mycoplasma contamination on the cellular metabolism of human pancreatic carcinoma cells PANC1 Multivariate analysis demonstrated that mycoplasma contamination induced significant metabolic changes in PANC1 cells Twentythree metabolites were identified and found to be involved in arginine and purine metabolism and energy supply This study demonstrates that mycoplasma contamination significantly alters cellular metabolite levels confirming the compelling need for routine checking of cell cultures for mycoplasma contamination particularly when used for metabolomics studiesThis work was financially supported by the Natural Science Foundation of China Grants 81522047 81573489 81373470 81320108027 the Natural Science Foundation of Guangdong Province Grant 2015A030313124 and the Guangzhou Health Care Collaborative Innovation Program Grant 201508020250
