| Project Title: | Effect of long-term exposure to graphene on skin cell metabolism |
| Project Type: | MS HaCaT Cells |
| Project Summary: | Graphene-derived materials are a family of nanomaterials with multiple potential applications in different fields such as biomedicine. It is therefore essential to understand their interaction with cellular barriers such as skin. In this work we evaluated the metabolic changes in human skin cells (HaCaT) exposed to different GRMs for 7 and 30 days. Objectives Endogenous metabolic profiles of control and graphene-treated keratinocytes have been studied using ultra-high performance liquid chromatography – mass spectrometry (UHPLC-MS). Keratinocytes were treated with graphene oxide (GO) from two different suppliers and with few layer graphene (FLG). Samples were collected one week and one month after the start of the treatment. The general aim of the project was to evaluate potential metabolic differences between: 1) Graphene-treated keratinocytes and control keratinocytes at one week; 2) Graphene-treated keratinocytes and control keratinocytes at one month; 3) Control keratinocytes at 1 month and 1 week; 4) Graphene-treated keratinocytes at 1 month and 1 week. Experimental Procedures A successful metabolic profiling experiment relies on the ability to determine changes in an organism’s biofluid or tissue complement of metabolites. Mass spectrometry coupled to ultra-high performance liquid chromatography (UHPLC-MS) is well suited to such analyses due to its high sensitivity, large coverage over different classes of metabolites, high throughput capacity, and wide dynamic range. In this study, one UHPLC-MS based platform was used to analyse endogenous analytes for inclusion in subsequent statistical analysis procedures used to study metabolic differences between the groups of samples. |
